Bogiehearth resistance furnace bearing and susceptible to collision parts with high strength refractory brick masonry, and the use of water glass during building the mud, so the strength increase.
Applications: the bogiehearth electric resistance furnace is a batch type furnace, it is used for normalizing, quenching, annealing and other heat treatments of large or medium metal parts.
