    摘要： Steel product in coil form such as sheet steel is uncoiled, then preheated, continuously transported through a lead bath containing chromium, then cooled, and finally recoiled. When the coiled steel does not have titanium, titanium is included in the bath in order to improve the corrosion resistance of the final product.

    摘要： An electric heating furnace which includes a conductive electric resistance heating element strip mounted within a chamber defined by walls of porous refractory insulating material. Terminal or mounting pins extend through the wall of insulating material and the heating strip are secured thereby. A sleeve of non-porous refractory material surrounds the portion of the pin within the wall of insulating material for electrically insulating the pin from the porous refractory wall material which may have a conductive layer of carbon build up therein under certain heat treating conditions.
