Pouring box
Minimum Order: 0
Quality/Safety Certification: 0.00
Pouring:heat preservation ,thermal shock resistance ,scour resistance, high strength, mechanical strike resistance
This product made of ZHONGNAI No.5 material is a prefabrication product.
Advantage:
excellent heat preservation ,thermal shock resistance ,resisting scour from aluminium and aluminium alloy fusant, high strength, mechanical strike resistance , standard finished size.
In the processing of round bar and square bar casting, allocated pouring box can stable surface of the fusant and support the lauder make fusant transmitting in the same level reducing the second impurity before casting.
Besides general specification, we offer products according customers' requirement
