Forging for rotor of industrial steam turbines
1. Smelting 1.1 For the production of forged parts, alkaline electric arc furnace smelting followed by external refining is recommended for steel ingots. Other methods ensuring quality can also be used for smelting. 1.2 Prior to or during the casting of ingots, the steel should unde...Read more -
Normalizing of the forging part
Normalizing is a heat treatment that improves the toughness of steel. After heating the steel components to a temperature of 30-50 ℃ above the Ac3 temperature, hold them for a period of time and air cool them out of the furnace. The main characteristic is that the cooling rate is faster than anne...Read more -
