Semi-Friable Fused Alumina
Semi−friable fused alumina is a new type of abrasive developed by our plant to meet the demands of the international market. With high quality bauxite as raw material, it is produced in the based of smelting the vice−white fused alumina, adjusting smelting process and ratio of raw materials, melting at the high temperature of above 2100℃ in the electric furnace, and using a special broken treatment technique. Since its hardness and toughness is between white fused alumina and brown fused alumina, it is called semi−friable fused alumina. It is characterized by high temperature resistance, corrosion and erosion resistance, low apparent porosity and stable thermal stability. Its grain is characterized by strong self−sharpening, sharp grinding edges and not easy to burn workpiece. After the grain of semi−friable fused alumina is processed, the relative ability of grinding resistance of semi−friable fused alumina increase, which is particularly applicable for grinding thermosensitive steel and alloy, low hardness, lower non−ferrous metal materials such as aluminum, copper, zinc, plumbum and non−metallic materials such as wood, plastic, and it is widely used for the production of bonded abrasives.

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.
