Ladle nozzle filling compound is made of high quality imported chrome ore, refined quartz sand and high refractoriness material, with good fluidity, fast flow, proper sintered layer thickness, anti-erosion and infiltration of molten steel. Artesian open casting ladle rate reach to 98%, etc. reducing the labor intensity, reducing oxygen drainage, improve the quality of steel products, to ensure the smooth casting process.

The NFC (Nozzle Filling Compound), including silicon stuffing sand, forsterite stuffing sand, high alumina stuffing sand and chrome stuffing sand, among which chrome stuffing sand has the most favorable effect in application.
Meanwhile our nozzle filling sands have been developed to meet the needs of steel making facilities worldwide. Each blend is carefully designed to enhance the free flow of steel from the ladle regardless of steelmaking practices. This is achieved through custom blending which affords each customer a product specific to their manufacturing needs.
Type of Nozzle Filling Compound:
1.Chromite Nozzle Filling Compound
2.Silica Nozzle Filling Compound
3.Forsterite Nozzle Filling Compound
4.High Aluminum Nozzle Filling Compound
