Qingdao Zhongye High-Temperature Materials Co., Ltd.

Silicon carbide graphite crucibles, composed of silicon carbide and graphite, are characterized by low porosity, high density, and uniform texture. They possess excellent thermal conductivity and chemical corrosion resistance, making them indispensable tools in high-temperature applications. They are widely used for melting and refining metals such as gold, silver, copper, aluminum, lead, zinc, zinc oxide, high-purity aluminum, and other alloys.

he long nozzle, typically a slender cylinder wider at the top and narrower at the bottom, features sheet metal reinforcement and an insulation layer connecting the ladle and tundish. It guides molten steel from the ladle to the tundish, preventing air from entering and causing secondary oxidation and nitrogen buildup, thus protecting the casting process and preventing molten steel splashing.

Submerged entry nozzles (SANs) come in various structural forms, including those with side holes and straight-through types. In continuous casting equipment, they are installed at the bottom of the tundish and inserted below the molten steel surface in the mold, acting as a refractory sleeve to control the flow and injection speed of the molten steel.

The integral stopper rod is formed by isostatic pressing, and its shape and size depend on the capacity of the tundish, the molten steel level, and the shape and orifice size of the tundish. Installed inside the tundish, it controls the molten steel flow, acting as a "valve" for the steel flow during the casting process. Made from high-quality white fused alumina, flake graphite, and other raw materials through scientific formulation and strict processes, it possesses reliable thermal shock stability and excellent resistance to corrosion, erosion, and oxidation.

Stable quality and excellent cold and hot strength, meeting the requirements for handling, installation, and use; Offers various rod head designs, from hemispherical and multi-curvature to conical, for effective and accurate control of high-temperature molten metal flow;
