Product Description
Magnesia-carbon brick is a non-burning refractory material made of high melting point alkaline oxide magnesium oxide (melting point 2800ºC) and high melting point carbon material which is difficult to be infiltrated by slag, adding various non-oxide additives and combining with carbon binder. As a kind of composite refractory, magnesia-carbon brick makes good use of the slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, and compensates the biggest disadvantage of poor spalling resistance of magnesia.
Product feature
Main features: good high temperature resistance, strong slag resistance, good thermal shock resistance and low creep at high temperature.

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.
