High temperature and radiation are the main hazards of rolling mills. Not only the surface of the heating furnace and the heated steel itself are heat sources, but also the ground covered with metal plates and mechanical equipment are heat sources, so the indoor and outdoor temperature difference of the rolling mill is very large in summer. Where a lot of heat is released, it is often accompanied by carbon monoxide. The rolling mill produces strong noise during rolling.
preventive measure
1. The fundamental measure to solve the occupational hazards in steel rolling production is to automate the production process and realize automatic operation.
2. The heatstroke prevention and cooling measures in the workshop (hot rolling workshop) are still indispensable. In order to eliminate high temperature and heat radiation, we should first strengthen the organized natural ventilation in the workshop, and set up heat insulation screens and local air supply in the workers' operating places next to the rolling mill to reduce the high temperature and heat radiation emitted by hot steel. Cranes and winch consoles can be equipped with air coolers, which can be cooled by refrigeration and air conditioning.
3, small and medium-sized rolling mills, if can't implement automatic operation, should try to reduce manual operation, improve the degree of mechanization, using positive, negative, vertical enclosure to improve working conditions. Shorten the time affected by high temperature and thermal radiation, and set up a cool and comfortable lounge near the workplace.
4. In order to prevent the influence of noise, you can use anti-noise earplugs or earmuffs. Workers who use radioactive elements for inspection must strengthen the protective measures for operators at work.
Causes of danger of rolling mill
Because most of the iron ore in China is lean, it is necessary to break the lean ore, select high-grade concentrate, and then burn the concentrate powder into artificial rich ore through sintering plant before it can enter the blast furnace for smelting.
The occupational hazards of sintering plant mainly include: high temperature and thermal radiation; The carbon monoxide produced when the tail of sintering machine is cooled by water spray is toxic and harmful; A large amount of dust is produced at the tail of sintering machine; Strong physical labor.
