热处理盐浴炉的热量散失,除加热工件和工夹具之外,炉壁的热传导和盐液表面的辐射热损失都很严重,而辐射热损失约占全部热损失的百分之五十。为了减少盐液表面的辐射热损失,我们选用了多种覆盖材料在中温和高温炉中进行了多次反复试验,从中找出了稻草灰这一较理想的覆盖材料,原料既便宜又易得,保温效果又很显著。经反复测定,节电效率达百
In addition to the heating of workpieces and jigs, the thermal conductivity of the furnace wall and radiant heat loss on the surface of the salt solution are both severe, while the radiant heat loss accounts for about 50% of the total heat loss. In order to reduce the radiant heat loss on the surface of the salt solution, we used a variety of coating materials in the medium temperature and high temperature furnace conducted repeated tests, from which the straw ash to find the more ideal covering material, both cheap and easy to get raw materials , Insulation effect is very significant. After repeated determination, energy-saving efficiency of one hundred
