Accident Prevention in Ironmaking

1. Gas poisoning accidents in ironworks pose the most serious harm, with many deaths occurring in front of the furnace and during maintenance operations. The main measures to prevent gas poisoning are to improve the integrity of equipment and minimize gas leaks as much as possible;
2. Install gas alarms in areas prone to gas leaks;
3. When carrying out gas operations, gas operators should wear portable gas alarms and assign dedicated personnel to supervise.
4. Burn accidents are also prone to occur in front of the furnace. The main preventive measure is to improve equipment level, and operators should wear protective clothing. Vehicle and machinery accidents are also prone to occur in the raw material yard and in front of the furnace.
5. When the volatile content of bituminous coal exceeds 10%, dust explosion accidents may occur in the preparation and injection system of bituminous coal dust. In order to prevent dust explosions, measures such as controlling the temperature of the coal mill and controlling the oxygen content in the air of the coal mill and powder collector are mainly taken. At present, China mostly adopts the method of injecting mixed coal to reduce the content of volatile matter.
