RTK fused cast abrasive resistance blocks adopt excellent raw materials: mullite clinker, imported bauxite and zircon sand, etc. They are made through melting and casting in electric arc furnace at high temperature. They are mainly used in the positions that require good abrasive resistance and high temperature resistance. For example: the sliding rail block of pusher type reheating furnace, and steel tapping spout of step-type heating furnace and garbage incinerator lining, etc.Â
According to the different contents of zirconia and crystallographic structure, the products can be divided into three brands: fused cast mullite abrasive resistance block (PRT-FM), fused cast zircon mullite abrasive resistance block (RTK-M), fused cast zircon-corundum abrasive resistance block (RTK-AZ21).

Commodity: Synthetic Cryolite Formula: Na3AlF6 M.W.: 209.95 Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.
