The Performance of Alumina Corundum Tube
1. Alumina corundum tubes have a high density, greatly reducing the secondary oxidation of molten steel during the pouring process and reducing the entry of inclusions into the casting model.
2. Alumina corundum pipes have high fire resistance (>1680 * C), corrosion resistance, smooth surface of the flow channel after pouring, and no corrosion during the pouring process. Good chemical stability, no chemical reaction with the molten metal (iron or steel) of the casting at high temperatures.
3. The high thermal strength and good thermoplastic properties of alumina corundum tubes can effectively prevent sand flushing and sand inclusion in castings, and reduce sand hole defects in castings.
4. The thermal expansion coefficient of alumina corundum tube is low and has almost no effect on the shrinkage of the casting. Reduced the phenomenon of tensile cracking caused by the pouring system.
5. The surface of alumina corundum tube is delicate and smooth, with low flow resistance and fast flow rate. The present invention can effectively reduce thermal cracks caused by thermal stress in castings due to various resistances caused by the gating system, mold, sand core, and casting structure.
