The utility model also discloses a heating furnace, which is a thermal equipment for melting pig iron in the casting industry and certain steel smelting plants. The working temperature of the guard is usually 1400 ~1 stone.. C.

Q:How many types of special refractories are there?

Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials

Q:What is the fireproofing requirements of external wall thermal insulation materials?

According to the "building external wall insulation fire barrier zone technical regulations" to be published: it is not less than the level B2. But before the procedure was published, it should be strictly implemented the document, level A is the best, I hope to help you, hope to adopt

Q:Who knows the fire endurance of rock wool color plate?

I'm glad to answer your question and offer you some of my experiences, for reference only. In fire?safety?rules, it can be divided into non-combustible component, hard-combustible component, combustible component according to the combustible degree of building materials. Rock wool board is building board recombinated artificially by fibers processed by coated steels and inorganic minerals like basalt mineral, because steel plate and rock wool which is the main components are non-combustible material, so rock wool board should be considered as non-combustible component. The fire endurance of rock wool board has its own judging criteria. Lose sustaining power, integrity and fire insulation function. Its fire endurance is within 2 hours.
