What is forging oxidation? How to prevent oxidation?

When the forgings are heated, the residence time is too long at high temperature, the oxygen in the furnace and the oxygen in the water vapor combine with the iron atoms of the forgings and the phenomenon of oxidation is called oxidation. Fusible formed by iron oxide adhesion on the surface of th... Read More

Why do die forgings fail?

The so-called forging die failure refers to the forging die can not be repaired to restore its use function of damage, that is, caused by the damage or scrap of the commonly said forging die. Because plays a forming die chamber of the function of the forgings, it directly in contact with the hot ... Read More

What is the inspection procedure for forging products?

The inspection procedure of forged products is as follows: ① All forgings should be cleaned before acceptance of finished products. Free forgings may not be cleaned. ② Before the acceptance of finished products, the forgings submitted for inspection and acceptance should be checked against the ac... Read More

What is the difference between hot forging and cold forging?

Hot forging is the forging of metal above the temperature of recrystallization. Increasing the temperature can improve the plasticity of the metal, is conducive to improving the internal quality of the workpiece, so that it is not easy to crack. High temperature can also reduce the metal deformat... Read More

What are the characteristics of special steel?

Compared with ordinary steel, special steel has higher strength and toughness, physical properties, chemical properties, biocompatibility and process performance. But special steel has some different characteristics from ordinary steel. For ordinary steel many people are more understanding, but f... Read More

What is the effect of thick rubbing on forging process?

Friction in forging is the friction between two metals of different composition and properties (alloys), between soft metal (workpiece) and hard metal (die). In the case of no lubrication, is the contact friction of two kinds of metal surface oxide film; Under the lubrication condition, the conta... Read More
