Energy consumption of raw material shear preheating:
In forging process, for large diameter or alloy steel raw materials, in order to improve the quality of blank section, make blank section flat, small slope, and prevent cracks in the section, raw materials - general need to preheat, such as low alloy structural steel preheating temperature of about 350C, that is, in the blue crisp area of steel material.
Can use river frequency or medium frequency induction heating furnace preheating, can also use gas, natural gas, fuel oil heating furnace preheating. Which way to cut raw materials (shearing, silver cutting) to carry out technical and economic analysis, from the material loss, energy consumption, tool life and productivity of technical and economic comparison. For example, the bad material with coarse ar and K (such as engine crankshaft ring material), if using shear cutting, its preheating energy consumption is large, it is advisable to use high band saw cutting, and the short bad material (such as engine connecting rod bad material), if using saw cutting F material, its material loss is much, it is advisable to use precision shear machine cutting.
U Energy consumption of billet heating:
In the inlay production, in order to improve the metal plasticity, reduce the deformation resistance, so that the billet plastic shape is good, the metal billet is heated correctly and the temperature is accurately measured in time, to improve the quality of general parts; It is of great significance to reduce fuel consumption. Heating of teng material is an important process in warm forging production.
Metal heating requirements, first of all to ensure the temperature and quality of billet heating, and meet the production beat of forging unit, in addition, but also less energy consumption and low cost, and environmental protection.
