内热式电极盐浴炉是一种应用很普遍的热处理加热设备。它的热源是电。消耗在电极和盐浴之间的电流都化为热能,一部分被加热工件吸收,一部分传给炉壁,另有很大一部分的热量却从盐面向空间辐射而散失了。电是工业建设的宝贵的动力,我们必须想办法节约。内热式盐浴炉节约用电,主要是减少热量从炉壁向外传导和从盐面向空间幅射。减少炉壁传导可以加大绝热砖和耐火砖的厚度;但这是有一定限度的,炉壁过厚,炉子体积就得增加,显得笨
Internal thermal electrode salt bath furnace is a commonly used heat treatment heating equipment. Its heat source is electricity. The current consumed between the electrode and the salt bath is converted into heat, and part of it is absorbed by the heated workpiece and partly to the furnace wall, while a large part of the heat is dissipated from the salt-facing space. Electricity is a valuable impetus to industrial construction and we must find ways to save. Internal thermal salt bath furnace to save electricity, mainly to reduce heat conduction from the furnace wall and from the salt to the space radiation. Reduce the furnace wall conduction can increase the thickness of insulating bricks and refractory bricks; but this is a certain limit, the furnace wall is too thick, the furnace volume has increased, it seems stupid
