机械工业部西安电炉研究所于1982年研制成功我国第一台ZCL—75—13型连续式真空淬火炉。该炉主要适用于中、小型精密轴承的批量真空淬火和航空零件、工模具等的热处理。该炉是一台三室卧式炉。加热室内的炉床上有四工位三料筐,即始终保持有三个料筐在加热室中,实现了按一定节拍进一料筐,同时 Xi’an Electric Furnace Research Institute of Ministry of Machinery Industry successfully developed China’s first ZCL-75-13 continuous vacuum quenching furnace in 1982. The furnace is mainly suitable for medium and small precision bearings batch vacuum quenching and aerospace components, tooling and other heat treatment. The stove is a three-chamber horizontal furnace. There are four stations on the hearth in the heating chamber, three baskets, that is, there are always three baskets in the heating chamber to achieve a basket according to a certain tempo, at the same time
