Precast blocks for EAF roof is made by steel fibre reinforced ultra-low cement castables with corundum, spinel and mullite as the main materials, and characterized with high strength, good thermal shock resistance, good erosion resistance and long service life.
Various types of ventilated bricks(ladle Porous plug) such as through-hole type, directional slit type, directional labyrinth type, internal integral type and external split type can be designed and manufactured according to user requirements, and the matching ventilation block locking mechanism can be designed according to user requirements.
Nobaking ramming mass for iron notch is made of corundum, high quality bauxite and silicon carbide, and bonded by resins and tar. Installation can be done by ramming.
Zhengzhou Caihua can supply carbon contained and carbon free repairing mixes. The carbon contained repairing mix is characterized with good flowability, good adhesion and long service life.
Dry rammmg mixes for EAF bottom are made from high quality magnesite and Fe2O3-CaO magnesite, and show the features of excellent resistance against steel penetration, superior erosion resistance, easily-sintering, high bulk density and easy installation.
Fused alumina, magnesium aluminate spinel, fused MgO and graphite are the main raw materials in use for Low carbon corundum-spinel brick. Low carbon corundum-spinel bricks, featured with high strength, better corrosion resistance and thermal shock resistance, are mainly used in the bottom and sidewall for low and ultra-low carbon steel production.
