What should be paid attention to in the forging process of heavy forging

What should be paid attention to in the forging process of heavy forging? Shanghai Zhiyuan Flange Forging Co., Ltd. pointed out that: heavy forging refers to large metal is applied pressure, through shaping to achieve its own purpose. This force is typically achieved by the use of a hammer or pressure. The forging process builds fine granular structures and improves the physical properties of the metal. In the practical use of components, a correct design can make the particle flow in the direction of the main pressure.

Heavy forgings should be noted in the forging process, including:



1. The process should be complete:



Heavy forging the materials are cut into required size, heating, forging, heat treatment, cleaning and inspection, although the working conditions for forging form varies, but has some common characteristics, such as moderate physical labor, dry heat microclimate environment, noise and vibration of the air polluted by smoke, so in the large forging workshop, Hazards vary according to the job, so follow the procedure strictly.



2, safety should pay attention to:

Workers are exposed to high temperature air and thermal radiation at the same time, resulting in heat accumulation in the body, heat and metabolic heat, will cause heat dissipation disorders and pathological changes. For 8 HOURS OF WORK, THE SWEAT OUTPUT WILL VARY FROM 1.5 TO 5 LITERS, OR EVEN HIGHER, DEPENDING ON THE SMALL GAS environment, physical exertion, and degree of thermal adaptation. In a small forging shop or far away from the heat source, the Behr heat stress index is usually 55 to 95, but in a large forging shop, the working point near the furnace or drop hammer machine may be as high as 150 to 190. Prone to salt deficiency and heat cramps. During the cold season, exposure to changes in the microclimate environment may promote adaptation to some extent, but rapid and too frequent changes may constitute a health hazard.
