Vice-White Fused Alumina

1.RS vice-white fused alumina

RS vice−white fused alumina is a new corundum product used to solve the problems in the process of the traditional vice−white fused alumina replacing the white fused alumina and tabular alumina according to the practical needs of refractory manufacturers and practical experience, which is jointly developed by the company and Luoyang Institute of Refractories. With high−purity alumina bauxite as main raw materials, RS vice−white fused alumina is made by a special technique in electric arc furnaces with high temperature above 2300℃ and  refining with longer time.It is characterized by high temperature resistance, corrosion and erosion resistance, low apparent porosity and stable thermal stability performance.
    It solves such problems as bursting, crazing and pulverising in the process of vice−white fused alumina replacing aluminum−oxygen based corundums such as white fused alumina. RS vice−white fused alumina is the ideal product which can substitute white fused alumina, compact fused alumina and tabular alumina in China .
    RS vice−white fused alumina sand (Barmac plastic) and micropowder (acid washing) produced by RuiShi plant is characterized by without bursting, without pulverising and high bulk density, good flow property etc, which can be widely used to manufacture variety of shaped refractory material products,corundum castable refractory,and other monholithic bulk refractory and caustic−burned corundum refractory products.

2.vice-white fused alumina

vice−white fused alumina is developed on the basis of brown fused alumina smelting. It can substitute compact fused alumina to make tapping launder castable refractory. It can also substitute white fused alumina and tabular alumina to make sliding plate, corundum bricks and abrasion−resistant castable etc, all of which have achieved the same effectiveness compare with using compact fused alumina and white fused alumina.

3.vice-white fused alumina for melt film precision casting

Melt film precision casting sand is the latest corundum products self−developed by RuiShi Company to meet the market demands. Based on the production of the vice−white fused alumina, and with special technology, it is produced by the careful organization of the researchers. The quality has reached the advanced level of similar foreign products through laboratory tests and production in practice of dozens of casting enterprises. And some performances of it can be adjusted or showcased according to the customers’ requirement. The precision casting sand of RuiShi Brand has high refractoriness, low thermal expansion coefficient, good thermal stability, strong air permeability, high intensity, easy to shell, high casting finish. It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratio is high as well. It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminum die casting industries, and can be processed in line with the demands of the clients.

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.
