What should be paid attention to in the forging process

1. The forging process includes: cutting the material to the required size, heating, forging, heat treatment, cleaning and inspection. In small manual forging, all these operations are carried out in a small place by several blacksmiths. Exposure to the same harmful environment and occupational hazards; in large forging workshops, the hazards vary from job to job.
Working conditions Although working conditions vary with different forging forms, they have some common characteristics: moderate-intensity manual labor, dry and hot microclimate environment, noise and vibration, and air pollution by smog.
2. Workers are exposed to high-temperature air and heat radiation at the same time, which causes heat to accumulate in the body. The heat combined with the heat of metabolism will cause heat dissipation disorders and pathological changes. The amount of sweat perspiration for 8 hours of work will vary with the small gas environment, physical exertion and thermal adaptability. Generally, it is between 1.5 and 5 liters, or even higher. In smaller forging workshops or far away from the heat source, the Behja's heat stress index is usually 55 to 95; but in large forging workshops, the working point near the heating furnace or drop hammer may be as high as 150 to 190. Easily cause salt deficiency and heat cramps. In the cold season, exposure to changes in the microclimate environment may promote its adaptability to a certain extent, but rapid and too frequent changes may constitute a health hazard.
Air pollution: The air in the workplace may contain smoke, carbon monoxide, carbon dioxide, sulfur dioxide, or acrolein. Its concentration depends on the type of heating furnace fuel and impurities, as well as combustion efficiency, airflow and ventilation conditions.
Noise and vibration: The forging hammer will inevitably produce low-frequency noise and vibration, but it may also have a certain high-frequency component, and its sound pressure level is between 95 and 115 decibels. Workers exposed to forging vibrations may cause temperament and functional disorders, which will reduce work capacity and affect safety.
