Mono-crystalline fused alumina
Mono−crystalline fused alumina (also known as SA), is produced by our plant, with bauxite , coal, scrap iron and pyrite as the main raw materials, in the process of smelting in the electric furnace with the temperature of 2050℃, breaking, hydrolysis and manufacturing. Products of various particles are formed naturally, instead of mechanical smashing. Because its particles are formed from single crystal, it has the advantages of good multi prism cutting edge and high hardness and toughness, strong grinding ability, and low grinding heat.It is a kind of high−grade grinding material . It is used to produce the high grade cutting and grinding tools.It is suitable for the material grinding of high hardness, high toughness such as high vanadium high speed steel, austenitic stainless steel, heat−resistant alloy steel, titanium alloy steel, especially for the grinding and processing of dry mill and easily burned workpiece.

Henan Ruishi Investment Group Co., Ltd., formerly known as Yichuan Ruishi Abrasives Co., Ltd., was founded in 1992. The company mainly produces all kinds of abrasives, special refractories and metallurgical materials. After nearly 20 years of rapid development, the company has developed into a stock−holding company with seven wholly−owned subsidiaries, including a bauxite calcination plant, a smelter plant, a sand−making plant, a new energy solar−powered wire cutting plant, a renewable resource company, and an international trading company. The company has the rights for import and export; it is also one of the top−100 export bases in Henan Province. The production base of the group covers an area of 440 mu. It has 350 employees, and a registered capital of 72 million yuan; it is equipped with six domestic first−class large−scale 3600KVA/360KVA high−temperature furnaces, and six automatic Barmac production lines; in order to ensure the stability of raw materials, the company built 4 shaft kilns, to be dedicated to firing first−grade alumina blocks used for smelting, which has an annual production capacity of up to 150,000 tons. The new−type energy−saving composite corundum developed by the company has a production capacity that ranks first in the industry worldwide. The products took the lead in the industry in passing the ISO9001: 2000 Quality Management System certification, which are exported to more than 20 countries and regions, including the United States, Russia, Japan, and Korea. In 2010, the total assets of the Group reached 159.09 million yuan; the sales income was up to 256.33 million yuan, and the taxes amounted to 24.93 million yuan, having created good social and economic benefits and made outstanding contributions to the society.
