Recently, Hollysys successfully signed the APC control project for the whole process of calcium carbide production of calcium Carbide Company, chlor-alkali Chemical Branch of Ordos Electric Power Metallurgy Group Co., LTD. Power Metallurgical Group has always focused on “industrial operation” and “scientific and technological innovation”, and is committed to building a world-class high-tech clean and recycling industry. With coal, natural gas, silica, limestone and other basic resources and electricity as the energy center, its products cover silicon-based alloy, chlor-alkali chemical industry, polysilicon photovoltaic industry, natural gas chemical industry, fine chemical industry, three waste utilization and other industries. Forming the development mode of orderly link of upstream and downstream products, resource recycling and value-added, the company is in the leading position in the industry in many fields, with annual sales of various products exceeding 10 million tons, which are exported to more than 20 countries and regions such as Japan, Korea, Europe, the United States, the Middle East and Southeast Asia.

Calcium Carbide Company is the pioneer industry of the chemical base built by the group. It is located in Qijing Industrial Park, Ordos City, Inner Mongolia, with advanced sealed calcium carbide furnace. In order to respond to the call of the state, to achieve energy conservation and emission reduction, through a series of technological innovation to achieve sustainable transformation. Among them, the whole process of calcium carbide factory APC is another key project created by calcium carbide Company. The successful implementation of this project will help enterprises achieve cost reduction and efficiency improvement, and it is the first in the industry, which will make a great contribution to the development of the whole industry.

The state will be the electric stone mine furnace included in the “two key one” management scope, at the same time must be in the future high energy consumption devices for energy conservation and consumption reduction, which also put forward higher requirements for the production of calcium carbide. Based on the control status of traditional calcium carbide project, in order to ensure safety and reduce manual operation, the whole process integration technology is applied to calcium carbide production to effectively solve the problem of traditional process.

The project of chlor-alkali chemical calcium carbide project adopts Hollyse APC optimization control technology of the whole process, which can accurately control each process parameter of calcium carbide, ensure the accuracy of process parameters, so as to ensure the safety and reliability of calcium carbide production and operation, and achieve the purpose of saving energy, reducing consumption, reducing cost and increasing efficiency. This project is based on the goal of safe production and high quality development, adhering to the principle of low-carbon, clean and efficient development. As the president unit of the industry association, the carbide Company of Ordos Electric Power Metallurgy Group Co., Ltd. takes the lead in creating the template project of full automatic optimization control of the whole process of calcium carbide.

This project involves the APC optimization control of 20 calcium carbide furnaces, 14 gas kilns, 7 vertical drying kilns and raw material delivery and production units, including a number of optimization control points: calcium carbide furnaces containing batching, batch statistics, electrode lifting, electrode pressure discharge, transformer shift, electrode soft sensing, load lifting, furnace pressure, furnace condition intelligent monitoring and judgment, etc. Gas kiln includes gas pressure regulation, automatic ash discharge, etc. Drying kiln includes kiln temperature regulation, automatic feeding, automatic discharging, etc. Raw material transportation includes automatic feeding, automatic cloth, etc.
