CH Refractories manufactures different brands ladle nozzle and collector nozzle for various capacity ladle, which can meet different service life requirements.
CH Refractories manufactures different brands ladle nozzle and collector nozzle for various capacity ladle, which can meet different service life requirements.
Ladle nozzle is made from corundum, bauxite, flake graphite, antioxidant and phenolic resin formed on heavy duty presses in harden steel or carbide die by using white fused alumina. To obtain maximum packing density, nozzles are fired at extremely high temperature in order to increase corrosion resistance to metal and slag the fired nozzles are further processed.
Advantages of CH Series ladle nozzle
● excellent thermal shock stability
●Long service life, Free mould charge
●Various brands meet different ladle requirements
●outstanding oxidation resistance and strong erosion resistance.

Mag carbon bricks are made of fused magnesia, high-purity magnesia and graphite, and are formed by high pressure molding and low temperature treatment. Different grades of mag carbon bricks can be selected according to different smelting conditions , service life in heats and smelting steel grades.
The anchor refractory brick is also called hanger brick. The anchor brick is similar to the material of the furnace lining castable, shaped by machine pressing, high temperature fired,has good thermal shock resistance and high strength,and is used on multiple heating furnaces to achieve good performance.
The refractory magnesia chrome refractory brick is a product made of high-purity magnesia and imported chrome concentrate, which is made by adding a small amount of additives and high pressure and high temperature.
