steel making production

In steel-making production, high-temperature operation line is long, equipment and operation types are various, lifting operation and transportation operation are frequent. The main hazard sources include high-temperature radiation, splashing and explosion of molten steel and slag, tempering combustion explosion of oxygen gun, gas poisoning, vehicle injury, lifting injury, machine injury, falling injury, etc. The main accident categories of steelmaking production are: burning and explosion caused by oxygen tempering, molten steel and slag splashing, lifting injury, vehicle injury, machine injury, object strike, falling from height, electric shock and gas poisoning accidents.

Statistics show that the main causes of safety accidents in steelmaking production are: man-made illegal operation and misoperation, poor working environment, equipment defects, unfamiliar operation technology, lack of supervision, inspection and guidance on the operation site, imperfect or lax implementation of safety regulations, unfamiliar operation technology, defects or lack of personal protective measures and supplies.


Rolling production

Steel rolling production is mainly composed of heating, rolling and finishing. In the production process, the process and equipment are complex, the operation is frequent, the working environment temperature is high, and the noise and smoke are large. The main hazard sources are: high temperature heating equipment, high-temperature logistics, high-speed machinery and equipment, gas, oxygen and other flammable and explosive and toxic and harmful gases, toxic and harmful chemical agents, electrical and hydraulic facilities, energy, lifting and transportation equipment, as well as the impact of operation, high temperature, noise and smoke.

According to the comprehensive statistics of the metallurgical industry, the safety accidents in the steel rolling production process are more serious in the whole metallurgical industry, higher than the average level of the whole industry. The main categories of accidents are: mechanical injury, object strike, lifting injury, burning, falling from high places, electric shock and explosion, etc. The main causes of accidents are as follows: illegal operation and misoperation, defects of technical equipment and protective devices, unfamiliarity of safety technology and operation technology, defects of working environment and conditions, and lax implementation of safety rules and regulations.
