Points to pay attention to during the forging process
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 by several forgers with both hands and hands in a narrow area. Exposed to the same harmful environment and occupational hazards; In large forging workshops, the hazards vary depending on the job position.
Although the working conditions vary depending on the forging form, they have certain common characteristics: moderate intensity of physical labor, dry and hot microclimate environment, noise and vibration generation, and air pollution by smoke.
2. Workers are exposed to both high-temperature air and thermal radiation, leading to the accumulation of heat in their bodies. Heat, combined with metabolic heat, can cause heat dissipation disorders and pathological changes. The sweating capacity of 8-hour labor will generally vary between 1.5 to 5 liters or even higher depending on the small gas environment, physical consumption, and thermal adaptability. In smaller forging workshops or far away from the heat source, the Bahr's heat stress index is usually 55 to 95; But in large forging workshops, the working point near the heating furnace or drop hammer machine may be as high as 150-190. Easy to cause salt deficiency and heat spasms. During the cold season, exposure to changes in the microclimate environment may to some extent promote its adaptability, but rapid and excessively frequent changes may pose a health hazard.
Air pollution: The air in the workplace may contain smoke, carbon monoxide, carbon dioxide, sulfur dioxide, or even acrolein, depending on the type and impurities of the heating furnace fuel, 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, with a sound pressure level between 95-115 decibels. Exposure of workers to forging vibration may cause temperament and functional disorders, reduce work ability, and affect safety.
