铝合金对淬火工艺要求比较严格,一般的箱式炉或井式炉难以满足,常常造成铸件过烧或强度偏低。通过反复研究,我厂制造了一台底开立式铝合金淬火炉,结构上作了较大改进。用该炉处理铝合金铸件,没有发生过烧现象,其抗拉强度也提高了1～12.5％。实践证明,该炉基本上满足了铝合金对淬火工艺的苛刻要求,具有广阔的应用前景。 Aluminum alloy quenching process more stringent requirements, the general box furnace or pit furnace difficult to meet, often resulting in castings over-burning or low intensity. Through repeated studies, I plant a bottom-open aluminum alloy quenching furnace, made significant structural improvements. With the furnace treatment of aluminum alloy castings, there is no over-burning phenomenon, the tensile strength also increased by 1 ~ 12.5%. Practice has proved that the furnace basically meets the demanding requirements of the aluminum alloy quenching process, has a broad application prospects.
