Brown aluminum oxide is made by high quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200C, and made into different grain sizes through crystal, choosing, crashing, magnetic, separating, screening, washing etc. It is characterized by its high hardness, good toughness and sharp shape in particles. Brown Fused Alumina(BFA) is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing Media. Refractory grade BFA is used as a raw material in the manufacture of high Alumina refractory. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.
Refractory mortar consists of refractory powder, binder and admixture. Almost all of the refractory materials can be made for the preparation of refractory mud used in the powder. The refractory clinker powder and the amount of plastic clay as binder and plasticizer made of ordinary refractory mortar, the room temperature strength is low, high temperature molding ceramic combination has a higher strength. With hydraulic, gas or hard thermal setting bonding material as a binding agent, said binding of refractory clay, which produce less than the formation of a certain chemical reaction prior to bonding temperature hardening. The particle size of the refractory mortar varies according to the requirements, and its limit size is generally less than 1mm, some less than 0.5mm or more. Selection of refractory mortar material, should be considered with the masonry refractory products consistent with the material. In addition to the fire-resistant mud in addition to the material, you can also use the coating method or spray method for the protective coating of the lining.
Silicon carbide powder refers to the use of JZFZ equipment for ultrafine crushing grading of micron-grade silicon carbide powder. Silicon carbide powder mainly for the 1200 # and 1500 # mainly due to silicon carbide powder is mainly used for the abrasive industry, so the fine powder grading has special requirements, the powder can not have large particles appear, so for the international and domestic product requirements, the general Production are used JZF grading equipment for high-precision classification. Domestic silicon carbide powder is mainly black silicon carbide powder and green silicon carbide powder. Silicon carbide differential effect Introduction: 1�Glass, The main raw material of various glasses. 2� ceramics and refractories: porcelain embryo and glaze, furnace with high silica bricks, ordinary silicon brick and silicon carbide and other raw materials.
