[Haichuan Chemical Engineering News] Dalian Heavy Industry signs EPC contract for 400,000 tons/year calcium carbide project
Thread Content
Dalian Heavy Industry’s subsidiary, Mechanical and Electrical Equipment Complete Set Co., Ltd., signed a general contract for the construction of a 400,000 tons per year calcium carbide production project. This project plans to construct four 66MVA closed calcium carbide furnaces, with an annual production capacity of 100,000 tons per furnace. It is the largest-scale and highest-capacity closed calcium carbide furnace project that Dalian Heavy Industry has undertaken to date. For the equipment of this project, the electric furnace process parameters will be selected based on the best economic and technical criteria. A completely closed cooling water circulation system will be employed to enhance environmental benefits, combining technological advancement with practicality. The goal is to ensure long-term stable operation of the equipment after the project is put into operation, thereby achieving both safe production and high output levels. At the same time, the project will adopt an intelligent material handling system with automatic tipping and loading of vehicles, along with a centralized control approach, to meet the requirements for efficient production with minimal or no human intervention; this has earned high recognition from customers.

On the evening of September 23, China Salt Chemicals issued a announcement stating that the company plans to invest 392 million yuan to upgrade the 40.5 MVA calcium carbide furnace at the calcium carbide plant owned by its wholly-owned subsidiary, China Salt Jilantai Chlor-Alkali Chemicals Co., Ltd. (hereinafter referred to as “Chlor-Alkali Chemicals”). Zhongyan Chemical Industry stated that this upgrade and renovation are aimed at fulfilling the requirements of national and regional industrial policies, ensuring the company’s production needs and future development, as well as reducing production costs. The announcement states that the chlor-alkali industry uses the calcium carbide method to produce polyvinyl chloride resin and paste resin; the 640,000-ton calcium carbide production facility is equipped with 12 calcium carbide furnaces, each with a capacity of 27.0 MVA. As part of this project, the 8 existing 27.0 MVA calcium carbide furnaces will be demolished, and 8 new 40.5 MVA calcium carbide furnaces will be installed in the existing factory building, along with relevant auxiliary equipment and facilities. The total investment for this project is estimated at 392 million yuan.

On October 23, the turnkey project for manufacturing 900,000 tons of calcium carbide per year, undertaken by Dalian Heavy Industry Machinery & Equipment Co., Ltd., a subsidiary of Dalian Heavy Industry (002204), for Shenhui Calcium Carbide Group Energy Development Co., Ltd. under Shaanxi Investment Group, was officially launched in the Jinjie Industrial Park in Shenmu, Yulin City, Shaanxi Province. The total value of this project exceeds 1.2 billion yuan, making it the largest single contract for a electric arc furnace or similar type of furnace under Dalian Heavy Industry’s portfolio in the past 3 years. It demonstrates that Dalian Heavy Industry remains at the forefront in the field of green and intelligent manufacturing of electric arc furnace equipment, and it holds great significance for driving the development of high-end, intelligent electric arc furnace products in China. It is worth noting that this project involves the supply of a complete set of production line equipment for 10 calcium carbide furnaces, as well as civil engineering work. It represents another significant achievement by Dalian Heavy Industry in adjusting its strategic focus; thanks to its leading technical expertise in the calcium carbide furnace market, extensive experience in general contracting for engineering projects, and strong performance record, it has managed to deliver this result despite the challenges posed by the pandemic. The Shenmu calcium carbide project is a key project in Shaanxi Province, aimed at fulfilling the strategic requirements for the transformation and upgrading of the calcium carbide industry, with the goal of establishing a modern green chemical demonstration park. The project will focus on the construction of smart factories, utilizing intelligent devices such as smart instruments based at the production site, intelligent inspection systems, robotic workers, and intelligent logistics solutions. Automation process control systems such as DCS, SIS, and GDS will be employed to achieve intelligence across the entire process, including electrode control in calcium carbide furnaces, the system for handling the ladles after they come out of the furnace, and ladle transportation. This approach aims to maximize the degree of unattended operation and inspection at the production sites.
