Haichuan – “My Story” Sharing Event 【100 Haichuan commemorative thermoses waiting for you】

I started working in June 1998 at Ningxia Darong Cyanamide Chemical Metallurgy Co., Ltd., driven by my dreams! We went to the calcium carbide decomposition Workshop 2; on that day, only the three of us from our class were assigned there, while the other two classmates were sent to the air separation workshop. My daily task is to use a shovel to feed the raw materials (limestone, coal, semi-coke, coking coal, and bituminous coal) into the feeder of the crusher; by the end of the day, my hands are covered in blisters!

There’s no story between Hai Chuan and me, but with a thermos bottle, our story begins

There is no such thing as an April Fool’s Day for safety; on that seemingly ordinary yet playful April Fool’s Day, the sun shone through the sparse clouds, illuminating every corner of the town and adding a touch of uniqueness to this day. And I, as an observer of this story, witnessed a scandal that arose between Li and Wang due to their attempts at being clever; it taught me deeply that safety is by no means a topic that can be taken lightly. Li, a person who likes to be clever on a daily basis, always manages to amuse those around him with various pranks in an inadvertent way. Wang, on the other hand, is the most meticulous and conscientious among us; he approaches his work with great care, and he has almost excessive requirements when it comes to safety. On that April Fool’s Day, the fates of these two people were quietly intertwined because of a casual “joke”. That day, Li had a sudden idea and decided to give Wang a \"surprise\". He secretly replaced the safety lock on an important machine in the workshop with a fake lock that looked similar but had no actual security functions. Li felt secretly pleased, thinking that when Wang would discover it, he would surely show a shocked expression, while Li could laugh heartily on the side, enjoying the pleasure of deceiving others. However, the events took a turn that was far beyond Li’s expectations. That afternoon, Wang carried out the routine equipment inspection, without any suspicion that the safety lock had been replaced. When he tried to start the machine for routine maintenance, without the protection of the safety lock, the machine started up accidentally. Fortunately, Wang reacted quickly and managed to avoid being hurt, but this close call was enough to send shock through everyone in the workshop. The news spread quickly, and management promptly stepped in to investigate. Soon, Li’s pranks were exposed, and he faced severe punishment as well as deep remorse. Seeing Wang’s slightly pale face due to shock, as well as the heightened tension among his colleagues as a result of this incident, Li finally realized that his so-called \"clever tactics\" were actually a complete disregard for the safety of others. Afterward, the company organized a safety education event attended by all employees. As a cautionary example, Li shared his own experiences on stage, expressing deep reflection on safety issues and his remorse. As for Mr. Wang, although he did not directly blame Mr. Li, he emphasized the importance of safety at the meeting, reminding everyone that in any industry, safety comes first and should never be taken lightly. That April Fool’s Day became an unforgettable lesson in the lives of both Li and Wang. It has taught us that safety is not an empty slogan, but a responsibility that each of us must keep in mind at all times and put into practice. From then on, whenever April Fools’ Day arrived, everyone would be more careful in choosing how to celebrate it, because in this town, safety comes before April Fools’ Day at all times.

My story: I have gone further and further down the path of the chemical industry. In November 2011, I entered a chemical company as an intern after graduating from school; my first experience was induction training, during which I had no real understanding of the chemical industry. After the 15-day training, we were assigned to various workshops. “It has a smell, it’s very noisy, but the workshop looks just like what you see on TV...” That was my first impression. A mentor was assigned to me, I got to know my colleagues, and I became familiar with the layout of the factory. Then, I started working in shifts, learning various processes, conducting inspections, and performing operational tasks... At that time, WeChat hadn’t been widely used yet; after work, I would walk around the dormitory area with cash to buy some food and drinks, and then either go to sleep or stay on standby. That’s how three years passed... Since my major was in petrochemical engineering, the company assigned me to the southern plant to learn other manufacturing processes, and another year passed in a blur. Once it’s completed, the new project will be set up, and then I’ll start learning about the new project. The process packages purchased were all in English, and with only a junior college education, my English skills were far from sufficient. I had no choice but to study secretly; once the company found out, it initiated a drive to improve English skills among employees. The preparation for this project took almost two years, during which time I also spent two years learning. The practical experience I gained in previous years was combined with what I learned during those two years. It wasn’t until about five years after 2011 that I finally understood what chemical engineering actually entailed and how the common equipment worked. The new factory started operating, and I went from being a newcomer to a veteran employee; during that time I met my girlfriend, bought a house, got married... It was another few years of working around the clock, and this period caused me to gradually lose touch with my friends and start feeling depressed. After analyzing myself, I realized that through all these years of experience, aside from chemistry, I don’t know anything else; ultimately, I had no choice but to continue developing my career in the field of chemistry. It was from this point that I truly regarded chemical engineering as my career and began to actively improve myself. In 2020, I stepped out of that comfort zone, went to another company, and embarked on a new journey. During that time, I obtained a bachelor’s degree, expanded my experience in the field of chemical engineering, participated in one plant operation to ensure its stable functioning, and trained key personnel at various levels within the plant. Over the course of two full years, I realized how lacking my knowledge was in the field of chemistry, and how inexperienced I was in terms of management. In 2022, I went to a company renowned for its strict management and took on the role of workshop supervisor. From project construction, design, procurement, installation... it is only when the tasks and responsibilities fall on one’s own shoulders that one realizes just how naive all the work done before was, and how superficial the knowledge possessed was. Three years of work on experiments, design, manufacturing processes, instrumentation, and equipment have led to overall improvements, and they have made me gradually more humble and cautious, more careful and thorough... By 2025, I am now someone who attracts the attention of headhunters; I continue to move further along the path in the field of chemistry. I keep striving to learn and improve, expanding my knowledge base, and I increasingly search for and acquire useful information from various sources. I hope that one day, when I look back on myself, I will be able to thank the person who worked hard back then, and thank Haichuan for giving me the opportunity to keep a record of it.

Should it be released all at once or in installments?

I also sent it; the moderator can take a look to see if it’s correct{:9001:}

It’s easy to talk about this topic, but it’s extremely difficult to actually make the decision to implement it – this is a problem that chemical industry professionals often face in their practical work. A bearing failure issue that occurred once with a turbo-type oxygen compressor. At that time, the bearing temperature was within the normal range, and vibration levels increased slightly (no vibration meter was installed on the equipment at that time, so judgments were made based solely on experience). At that time, it seemed necessary to stop and switch to another piece of equipment to continue production. But the other device wasn’t very reliable either (the devices from that time were among the first domestically produced ones; they didn’t work without problems even after a year of continuous use, unlike today’s devices). ), so it is necessary to inform the duty supervisor in a timely manner for approval. At this point, not only was it difficult for the operator to decide to shut down the machine, but the mechanical supervisor was also afraid of taking responsibility if nothing went wrong; thus, the deadlock and shifting of blame continued. However, the person in charge of production on site could no longer bear it and immediately organized an emergency shutdown. . . . . Upon subsequent disassembly, it was found that the remaining thickness of the tungsten layer in the bearing bush was “as thin as a cicada’s wing”. Coincidentally, another identical equipment accident occurred later. The bearings of a turbine air compressor encountered the same problem; it was during the morning shift change, and the management also went to the site to take a look. In the end, it was decided to first contact the units at the back before shutting down the machine,,, haha, but then a terrifying phenomenon occurred: sparks appeared at the seal of the bearing box,,, and the staff on duty had to inform the supervisor before they could carry out an emergency shutdown. Upon disassembly, it was found that the rotor main shaft impeller had worn out excessively and had to be discarded. To determine the appropriate level for an emergency stop, a comprehensive assessment is required, one that takes into account the actual needs of production. But it’s better to take precautions in advance, maintain the equipment properly on a daily basis, and follow the operating procedures strictly in case of similar situations. It is essential to act in a well-founded manner, ensuring that neither the equipment nor personnel are harmed. There are many similar topics; the moderator’s question is very meaningful. Thank you!
