We have elbows of 90 degree, 30 degree, as well as 45 degree. Besides, we can design for the customized shape of bent pipe to meet a special requirement.
- The high density of the ceramic tube for casting greatly reduces the secondary oxidation of the molten steel in the pouring process, and reduces the inclusion of objects into the casting body.
- The inner surface is smooth with small resistance, so the molten steel has fast speed, which can effectively reduce all kinds of resistance ,such as receive gating system for casting, casting sand core and the casting structure itself, which can also reduces thermal cracking cased by heat stress within the castings.
- This ceramic tube has high refractoriness (>1700 ℃ ), abrasion resistance, convenient to use, can connect to straight pipe, elbow, adapter bonnet, three-branch pipe, five-way pipe and the variable diameter gate with the adhesive tape freely as you want. When you use this ceramic tube in gating system, there is no need to use the coating or painting and runner bricks, so it can reduce your cost.
- The corrosion resistance of Huaguang’s ceramic tube is superior to runner brick greatly. Compare with runner brick, Ceramic tube generates low waste, convenient to clean. It also can improve the utilization rate of the sand, and save time and labor.
- The tube also has good chemical stability, it won’t cause chemical reaction with metal liquid(molten steel or molten iron) under high temperature. After pouring, the surface of the pouring channel is smooth, and the pouring process is free of corrosion.
- The tube has high thermal strength, good thermal plastic. It can effectively prevent sand washing or inclusion, and reduce the defects of the casting sand holes. The thermal expansion coefficient is low, and the shrinkage effect of casting is small, which reduces the cracking phenomenon in the gating system.
HuaGuang’s quality products are widely used in nuclear power, wind power, aviation, aerospace, automotive, military industry, iron and steel, rail transportation, petroleum machinery, machine tools and many other fields, suitable for all kinds of sand casting process.
