Fused magnesium aluminum spinel;
Sintered magnesium aluminum spinel.

Magnesium aluminum spinel

Fused magnesium aluminum spinel of Ruishi Brand is produced by mixing the industrial alumina with the purity no less than 98.5% and the caustic−burned magnesia with the purity no less than 96% and an appropriate amount of high purity magnesite , and smelting with high temperature in the electric arc furnaces,and can be processed with different size particle, fine powder and superfine powder. Its grain is well developed with the features of compact texture and uniform structure, which is high−grade raw material for producing high quality refractory products with high intensity, good thermal shock resistance.
Fused magnesium aluminum spinel of Ruishi Brand has the characteristics of high temperature resistance, high density, low water absorption, low thermal expansion coefficient, good thermal stability, and strong corrosion resistance. It is ideal material to cast sliding plate, nozzle bricks, ladle bricks and open hearth furnace bricks, as well as the basic material for ecotone bricks of large cement kilns, medium cement kilns, refractory castable materials and first−class and medium−class kiln furniture. And it is widely used in iron and steel smelting, cement rotary kiln and glass furnace.

Sintered magnesium aluminum spinel is chosed the high−quality bauxite and magnesia as the raw material, through multilevel homogenization process, and sintered more than 1800 treatment. It is characterized by erosion−resistance, abrasion−resistance, strength spalling ability, slag−resistance, stability thermal shock resistance, high temperature−resistance performance and so on. It is the perfect raw material of cement, rotary lime kiln and high temperature resistance using magnesium aluminum bricks, ladle castable refractory material and so on.

Company Information

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.
