一、感应器快换问题的提出一九七五年,沈阳铸造厂二车间为了配合一条无触点气动微震造型自动生产线的生产,采用了冲天炉——工频电炉双联熔炼的新工艺,建造了两台3T有芯工频感应电炉,用于铁水的升温和保温。当时,这两台炉子的感应器都是不可拆的,感应器和炉体的炉村为一整体,在使用石英砂为炉衬材料、粘结剂为硼酸时,炉子的使用寿命见表1。 First, the sensor quick change proposed In 1975, Shenyang Foundry two workshops in order to meet the production of a non-contact pneumatic microseismic modeling automatic production line, using a cupola - power frequency electric furnace double melting new technology, Two 3T core frequency induction furnaces were built for the heating and insulation of hot metal. At that time, the two furnace sensors are not removable, the furnace sensor and furnace village as a whole, the use of quartz sand lining material, binder for boric acid, the life of the stove in Table 1.
