Lightweight forsterite brick products and function of light forsterite brick
A weak alkaline refractory. It contains 35%~55% magnesium oxide and a considerable amount of magnesium ferrite. The molar ratio of MgO/SiO2 is 0.94~1.33. The main crystalline phase is forsterite 2MgO. SiO 2 (abbreviated as M2Si). The regenerative brick has high refractoriness and load softening temperature, and strong anti-corrosion ability of iron. With peridotite, serpentine, pure peridotite and talc as raw materials, proper amount of sintered magnesia was added and sintered in an oxidizing atmosphere. The firing temperature increases with the increase of magnesia content. It can be used as lining for non-ferrous metal smelting furnace, steel-making open-hearth regenerator and cement rotary kiln.
