Low density of the zirconia nozzle as flow control refractory in the tundish to smelt special steel products
Products Features:
Our low density of the zirconia nozzle inserts as flow controlling of steel liquid and slag refractory in the tundish widely used in the large capacity of tundish in steel plant. It has the better quality quality, longer working life than our normal 5.4g/cm3 one, after embedded in the alumina or corundum quality body, can be used in the sliding system of ladle and tundish directly, do not desired to heat before using. Especially used for smelting the special high grade steel types, such as low carton steel, alloy steel etc.
Production Process
Our low density of the zirconia nozzle insert as flow control refractory is made of the high quality of e-fuzed magnesia and zirconia grain and sand, bonding agent, through the the automatic system mixing, drying, pressing, inspecting, sintering, etc. series system process, then pack into the carton, and wooden box with the desired shipping mark sticked, then deliver to the china mainland and oversea from our factory.
Inspection times in production process
1. After Mixing, inspect the water content of material,
2. After pressing, inspect the size,missing angle, etc. of semi-finished products
3. After sintering, inspect the size, missing angle, cave, etc. of finished products
4. Before packing, inspect the size, missing angle, cave,of the finished prodcuts again.
