Water cooled melting furnace - having angle iron protrusions on inner jacket giving increased adhesion of refractory

摘要

Melting furnace esp. electric-arc furnace has a furnace wall with one or more cooling water jackets of welded sheet steel above the level of the molten mass. The jacket surface towards the inside has protrusions to aid adhesion of a protective refractory coating, formed on it. Water jacket wall towards the inside of the furnace is =15 mm. thick, and the protrusions are formed by angle iron. The refractory mass initially applied serves as the protective coating. Wall thickness is 20-25 mm., and the protrusions are 20-50 mm. long. They can be made from sections of hollow angle iron, open towards the top.
