Refractory Tundish Monoblock Stopper In CCM Continuous Casting Machine
Monoblock Stopper Used In Continuous Casting Machine Monoblock Stopper Factory Supplier
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.
