Occupational Hazard Factors and Preventive Measures in Rolling Mills

Rolling is the use of rolling mill steel rolling steel, billet rolling into a variety of shapes of steel. It can be divided into hot rolling and cold rolling. The production process of both is basically the same.

(I) Occupational hazards

The main hazards are high temperature and radiation.

Not only the surface of the heating furnace and the heated steel itself is a heat source, but also ground and machine equipments, which are paved with metal plates, are all heat sources. Therefore, the indoor and outdoor temperature difference in the rolling mill is large in summer. In places where a lot of heat is released, carbon monoxide is often accompanied. The rolling mill produces strong noise during rolling. If radioactive detection equipment is used for product quality inspection, there is radiation hazard.
(b) Preventive measures

1. The fundamental measure to solve occupational hazards in steel rolling production is to automate the production process and achieve automation.

2. The measures to prevent heatstroke in the workshop (in the hot rolling workshop) are still indispensable. In order to eliminate high temperature and heat radiation, the organization's organized natural ventilation should be strengthened firstly. Heater screens and local air supply should be installed at the workers' location near the rolling mill to reduce the high temperature and heat radiation emitted by the red hot steel. Cranes and rolling mills can install cooling fans and use cooling and air conditioning to cool down.

Small and medium-sized steel rolling mills, if they cannot implement automation, should minimize manual operations and increase the degree of mechanization. Positive, negative and vertical fences should be used to improve working conditions. Shorten the time that is affected by high temperature and heat radiation, and set up a cool and comfortable lounge near the workplace.

To prevent noise, use anti-noise earplugs or earmuffs.

When working with radioactive elements to perform inspections, it is necessary to strengthen protective measures for the operators.
