What are the precautions for forging

1. The forging process includes: cutting the material to the required size, heating, forging, heat treatment, cleaning and inspection. In small-scale manual forging, all these operations are carried out in a small space by several forges. They are all exposed to the same hazardous environmental and occupational hazards; in a large forge, the hazards vary from job to job. Working conditions Although working conditions vary by forging form, they share some common characteristics: moderate-intensity manual labor, hot and dry microclimate environment, noise and vibration generation, and air pollution by smog.

2. Workers are exposed to high temperature air and heat radiation at the same time, which leads to the accumulation of heat in the body. The heat plus the heat of metabolism will cause heat dissipation disorders and pathological changes. The amount of perspiration for an 8-hour labor will vary with the small gas environment, physical exertion, and degree of thermal adaptability, generally between 1.5 and 5 liters, or even higher. In smaller forging workshops or far from the heat source, the Berja II heat stress index is usually 55~95; but in large forging workshops, the working point near the heating furnace or drop hammer may be as high as 150~190. May cause salt deficiency and heat cramps. Exposure to changes in the microclimate environment during the cold season may promote adaptation to some extent, but rapid and too frequent changes may pose a health hazard.

3. Noise and vibration: The swaging hammer will inevitably produce low-frequency noise and vibration, but it may also have certain high-frequency components, and its sound pressure level is between 95 and 115 decibels. Exposure of workers to forging vibrations can cause temperamental and functional disorders that reduce work capacity and affect safety.
