Main Product Introduction
1.Low Cement Refractory Castable:
The refractory castable has been widely used in metallurgy ,building material.,petrochemical and other industrics.
The newly developed wearable refractory castable has been brought into use on water cooling module of medium-small sized blast furnace by Fushun Xinfu Iron & Steel Group Co. Ltd etc , which achieved good effect. It can replace burnt high alumina brick and fire brick to reduce the cost
of blast furnace.
2.Bottom Ramming Mass For EAF:
Bottom ramming mass for EAF is made of high- quality MgO-Fe sand and MgO-C sand by reasonable granularity distribution.
It has the characteristics of easy construction and well monolithic lining. It is used for the bottom,slope and other part of high power EAF, ultra high power EAF.
3.Fluxing Agent :
The Chromium fluxing agent produced by our company is used for all kinds of molten steel containers with a good effect of natural flow which can achieve over 99%.Magnesium fluxing agent is used for all kinds of electric furnaces with a natural flow rate over 95%.
