铸造铝合金热处理后的质量,不仅与正确选择加热规范有关,而且与冷却时所采用的淬火介质和冷却方式也有很大关系。铸铝件淬火后的开裂和变形往往就是由于淬火介质和冷却方式选择不当所引起的。铸造铝合金常用的淬火介质是热水,一般是用蒸汽或电来加热的,消耗电能较多(如我厂曾使用的1.2立方米淬火水槽用电炉加热,每处理一炉需要消耗360度的电能);
Cast aluminum heat treatment quality, not only with the correct choice of heating specifications, but also with the cooling medium used by the quenching and cooling methods also have a great relationship. After quenched aluminum casting cracking and deformation is often due to quenching medium and cooling caused by improper choice. The commonly used quenching medium for casting aluminum alloy is hot water, which is usually heated by steam or electricity and consumes more energy (for example, 1.2 cubic meters quenching sink used by our factory is heated by an electric furnace and consumes 360 degrees for each furnace Electricity);
