CH refractories can design and produce argon purging and non-purging monoblock stopper as per the conditions of continuous casting processes in steel mills. The head of monoblock stopper can be Al2O3-C , MgO-C, Spinel-C or ZrO2-C based according to the types of steel to cast.
CH refractories can design and produce argon purging and non-purging monoblock stopper as per the conditions of continuous casting processes in steel mills. The head of monoblock stopper can be Al2O3-C , MgO-C, Spinel-C or ZrO2-C based according to the types of steel to cast. The body and slag zone of monoblock stopper are Al203-C based. The monoblock stopper from CH refractories can provide stable control of molten steel casting, good corrosion resistance, desired thermal shock resistance and high tenperature strength. Monoblock stopper can last more than 35 hours used for billet caster and more than 20 hours for slab caster. Monoblock stopper is suitable for almost all steel casting from normal carbon steel, low carbon steel, ultra-low carbon steel, high Mn steel to high O steel.

Zirconium corundum brick is also named AZS brick. It is based on three chemical components of the Al2O3-ZrO2-SiO2 ternary phase diagram and widely used for glass kiln. The glass kiln brick is arranged according to the order of its contents.
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.
Corundum castable refractory is divided into cement-free corundum castable refractory and cement corundum castable refractory. Also there are different kinds of corundum castables refractory made by CH refractories company according to different raw material.
