Melting occurred during the heat treatment of the sulfuric acid process cooler

It is possible that the excessive temperature during the heat treatment process caused abnormal reactions among the elements and compounds in the steel, generating a large amount of heat energy, which led to melting and intense burning. Furthermore, it may also be due to improper design or operation of the heat treatment furnace, resulting in inaccurate temperature control and further exacerbating the accident. To this end, it is recommended to carefully examine the design, operation, and maintenance of the equipment before the next heat treatment, paying special attention to the accuracy of temperature control in order to prevent similar incidents from occurring again. .

Is it possible that the furnace has reached an oxygen-rich state?

The reasons for the damage to the cooler and the furnace may include the following aspects: 1. Material issues: The steel materials used in the manufacture of the cooler and furnace may contain impurities, cracks, and other problems, which can lead to melting or burning at high temperatures. 2. Design issues: The improper design of the cooler and furnace leads to problems such as excessive temperatures and high stress, resulting in melting and breaking. 3. Processing issues: During the processing, problems such as improper procedures and insufficient processing precision may occur, leading to excessive internal stress in the steel, which in turn causes melting, cracking, and other phenomena. 4. Heat treatment issues: During the heat treatment process, problems such as loss of control over the equipment, excessive temperatures, and sudden abnormalities can occur, leading to excessive heating and damage of the steel or the formation of thermal cracks, which in turn can result in melting and burning. The above are the reasons that may cause damage to the cooler and the furnace; the specific causes can only be determined through investigation and analysis. To prevent such accidents from occurring again, it is necessary to investigate and analyze the causes of the accidents and take targeted measures, such as improving the quality control of materials and equipment, refining process flows and operating procedures, and strengthening supervision over the heat treatment process. At the same time, it is also possible to strengthen employee safety awareness training, improving their understanding and capabilities regarding equipment operation and accident prevention.
