Considerations for forging
Jan 07, 2017

Forging process should pay attention to where
1. forging process include: cutting the material into the desired size, heating, forging, heat treatment, cleaning and inspection. In a small artificial forging, all from a few forging hand and laid in a small premises. They are exposed to the same harmful environmental and occupational hazards, and in the heavy forging workshop, hazard varies with the job.
Working conditions while working conditions for forging forms vary, but share some common characteristics: moderate-intensity manual labor, dry and hot climate environment, noise and vibration, air contaminated by smoke.
2. workers are exposed to high temperature air and heat radiation, resulting in accumulation of heat in the body, heat combined with metabolic heat may cause heat disorders and pathological changes. 8-hour labor of perspiration with little gas environment, physical exertion, and varies with the degree of thermal adaptation in 1.5~5 litres, or even higher. In a small forge or farther away from the heat source, heat stress index is usually the beihaer 55~95, but in heavy forging workshop, close to the furnace or drop weight machine work point may be as high as 150~190. Salt-prone and heat cramps. In the cold season, exposed to changes in microclimate environment may promote their adaptation to a certain extent, but rapid and frequent change, could pose health hazards.
Air pollution: the site may contain dust in the air, carbon monoxide, carbon dioxide, sulfur dioxide, or containing Acrolein, its concentration depending on the type of furnace fuel and contains impurities, as well as combustion efficiency, airflow and ventilation conditions.
Noise and vibration:-Hammer will produce low frequency noise and vibration, but may also have a high frequency components, the sound pressure level 95~115 decibels. In workers exposed to vibration of forge, temperament and may cause functional disorders, reduced working capacity and safety implications.
