Product Description

Product introduction

 

Aluminum-magnesium carbon brick is a new variety developed in recent years, based on the aluminum-magnesium brick and magnesium carbon brick, and its production process is mostly like magnesium carbon brick. It is made of Al2O3, MgO and C as the main components, Containing Al2O3 of 60% ~ 69%, Mgo of 7% ~ 14%, C of 5% ~ 12%. Aluminum-magnesium carbon brick(Water glass bonded) use Level one or two bauxite clinker for refractory aggregate, Level one or special high-aluminum powder for refractory powder, and blended 8% to 13% the first and second grade metallurgical magnesia powder. Carbon material use electrode powder, earth-like graphite or flake graphite, the amount of 3% - 8%, use water glass solution (m = 2.4 ~ 3.0) as a binder, after forming treated in 200 ~ 250 ºC low temperature after forming, the brick is finished. The refractoriness of the Water glass combination aluminum - magnesium carbon brick is 1770 ° C, and the 4% load softening temperature is 1320 to 1340 ° C, which is caused by the addition of Na2O. If using high modulus water glass in which the Na2O is less,  load softening temperature increased to 1410 ºC, refractoriness is 1790 ºC. This kind of refractory brick is widely used in the small and medium ladle because of its good performance and low price. The refractory brick is used in the cast steel ladle, and magnesium carbon brick is used in the slag line masonry, its life is 50 to 100 times.

Product feature
1. good resistance to slag erosion
2. good thermal shock resistance
3. low rebirth line expansion.
In order to improve its oxidation resistance, Si powder, Al powder, SiC powder or ferrosilicon powder can be added in the ingredients, use resin as binder, molding in high pressure. It can be used after 200 ~ 300 ºC treatment, without Calcined.

Company Profile

The magnesia-carbon brick produced by gongyi city Zhenhua Furnace Charge Co., Ltd. was issued the production license by the Ministry of Metallurgy in 1995, and one of the standard units designated by the national standard of aluminum, magnesium and carbon. In 1998, it passed the ISO--9002 quality system certification. The company has professional technical team and advanced testing equipment, which can ensure the quality and the needs of the majority of users. In recent years, our company has made good research on steel ladle lining bricks, electric furnace lining bricks and rotary furnace lining bricks, especially for refining ladle bricks outside the furnace. The corundum spinel prefabricated low-carbon magnesia-carbon brick developed jointly with Wuhan Iron and Steel Institute has been used for 250 times in the 300t F refining ladle of No.3 Steelmaking Plant of Wuhan Iron and Steel Co., Ltd., which is an advanced product in China at present. The low-carbon slag line brick won the first prize of scientific progress by the expert judges of Hubei Scientific Research Department in 2012, and the aluminum silicon carbide carbon brick was well evaluated in the 300t iron ladle of Shougang Jingtang Company. In 2000, the aluminum-magnesium-carbon steel package and magnesium-carbon slag brick were exported to Austria, etc. Gongyi city Zhenhua Furnace Charge Co., Ltd. takes "respecting contract, keeping reputation, quality first, customer first" as its tenet, and has been named as "respecting contract and keeping reputation" by gongyi city Industrial and Commercial Bureau for several consecutive years. Dedicated to providing quality services at home and abroad, sincerely hope that customers will visit and negotiate business.
