Upper and lower nozzles are resin bonded products based on corundum, magnesium aluminate spinel and graphite as main raw materials. Nozzle and well block for ladle have excellent thermal shock resistance, high temperature strength and good corrosion and erosion resistance.
Upper and lower nozzles are resin bonded products based on corundum, magnesium aluminate spinel and graphite as main raw materials. Nozzle and well block for ladle have excellent thermal shock resistance, high temperature strength and good corrosion and erosion resistance. Well blocks of corundum based, corundum-spinel based and corundum-chrome based have excellent high temperature properties, which can ensure longer service life in use together with nozzles as part of slide gate system.

The silica mullite firebrick produced by our company is made from high-grade bauxite clinker and high-quality silicon carbide as the main raw materials and firing at high temperature.
Castables for ladle working layer is made from high purity corundum, magnesium aluminate spinel and fused MgO as main aggregates, superfine powder bonding technology and appropriate additives.
The high-strength alkali-resistant refractory castable has good resistance to alkaline gas and slag, and has a long service life. High strength alkali resistant castable is mainly used for lining of other industrial furnaces such as kiln door cover, decomposition furnace, preheater system and pipeline system.
If you need our products please write down any questions, we will reply as soon as possible.
