High Hot Strength Brown Alumina F100 - F120 For Monolithic Refractory
Brown Fused Alumina is fused in the electric-arc furnace under the high temperature of above 2250°C with high quality bauxite as raw material and matched by the carbon material and scrap iron .The degree of refractory is more than 1850°C.
In order to meet the demands of the refractory industry, we independently develop and produce RS brown fused alumina. Which is characterized by high purity,good crystal,strong fluidity,low coefficient of linear expansion,good corrosion-resistance and so on. RS Brown fused alumina could not burst,pulverise and craze in using course.
Production process: sorting of the raw materials→electrolytic smelting→crushing→magnetic separation→filter→physical and chemical testing→packing→warehousing

5)Low coefficient of linear expansion
Brown fused alumina melt film precision casting sand is the latest corundum products self- developed by RuiShi Companytomeetemeedemands. Based on the production of the brown fused alumina and with special tehology, it is produced by the careful oganizincd eresearchers. The quality has reached the advanced level of similar foreign products through laboratory tests and productioninpracticeofdozensof casting enterprises. And some performances of it can be adjusted or showcased according to the customers' requirement. Theprecisioncatiosand of RuiShi Brand has high refractorinesss, low thermal expansion cofficient, good thermal stability, strong air permebilit,higitensty,easto shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratioishighaswell.It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminumdiecasting industries, and can be processed in line with the demands of the clients.
