Brown Aluminum Oxide 16 Grit Suppliers Malaysia

The SC method was developed by Sumitomo Metal Industries, Japan in 1980(brown fused alumina). TKawasaki method. The Kawasaki method was developed by Kawasaki Iron and Steel Company of Japan(aluminum oxide abrasive). The pre-reduction device is a fluidized bed, the final reduction device is a shaft furnace, the working temperature of the pre-reduction furnace is 900 ° C, and the working temperature of the final reduction furnace is 1500-1550 ° C.

The main features of the Kawasaki method are: available powder ore(brown aluminum oxide); productivity is double that of blast furnace, and productivity per unit volume is 2 ~ 10t / m · d; investment is low and equipment cost is 2/3 of blast furnace; it can be used to produce ferroalloy. Problems with the Kawasaki method: A part of low-quality coke is required. SC law (Sumitomo law). Problem with SC method: 25% low quality coke is needed(silicon carbide abrasive). Plasmaselt method (plasma melting method).


he pre-reduction device is a tight furnace, the final reduction device is a melter gasifier, the shaft furnace working temperature is 800 ~ 900 ° C, and the melter gasifier is about 1500(brown aluminium oxide). The simple circle of the SC method intermediate test device is shown in the figure. Problems with the Inred method: simple process, equipment investment, gas power generation, energy conversion loss of about 40%(aluminum oxide grit); flash smelting is not very stable; molten iron contains sulfur and high phosphorus.


CGS method(white alumina). The main features of SC production: non-coking coal available; high production efficiency. The pre-reduction device is a two-stage fluidized bed with a pre-heating fluidized bed and a pre-reduction fluidized bed(green silicon carbide). The final reduction device is a plasma melting vertical Furnace (coke filling type), the working temperature of the pre-reduction device is 700 ~ 800 ℃, and the working temperature of the final reduction device is 1500C.


The Plas-maselt method was developed by Swedish SKF company in the early 1970s(black corundum). Inred method main production characteristics: non-coking coal and lead, zinc, arsenic and other alkali metal elements with high content; low production costs; flash smelting(synthetic corundum). Fast response and high production efficiency: high volatile coal can be used, ore powder, pyrite slag and iron and steel plant dust can be used; besides iron smelting, steel, lead and chrome iron can also be used.


The CGS method is researched by Sumitomo Corporation in Japan(pink corundum). The pre-reduction device is a fluidized bed, the working temperature is 800 ~ 900 ° C, the final reduction device is a converter, and the working temperature is 1500C. CGS production features: can refine stainless steel; can smelt chromium ore and nickel oxide. The larger the scale of production, the more provincial the investment in infrastructure(black silicon carbide). High production efficiency, smelted steel types and good quality.


In 1952, the top-blown oxygen converter steelmaking method came out and soon developed into the world's largest production steelmaking method(emery abrasive). It was first successfully tested by the Swedish Robert and Duner, and then a 30t converter was built in the Austrian Linz Steel Works and the Donawitz Steel Works(120 grit aluminum oxide harbor freight). This converter takes two steels The prefix of the plant name is named LD converter, also called BOF (Basic oxy-gen furnace) or BOP method.
