Gating system ceramic tube for casting low price

Applicable:

    This type of product is suitable for resin sand, sodium silicate sand, precoated sand and some other formative technology. It is used for casting high manganese steel, alloy steel, stainless steel, carbon steel, high chromium cast iron, ductile iron, grey iron castings, etc.

Main advantages:

1.The high density of the ceramic sprue 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. 

2.Ceramic sprue tube for casting has high refractoriness (>1700 ℃ ), abrasion resistance, convenient to use.

3. The corrosion resistance of the Ceramic sprue tube for casting is superior to runner brick greatly. 

4. The sprue tube has high thermal strength, good thermal plastic. 

       The physical and chemical index:

Refractoriness>1700℃

Al₂O₃content ≥45％

Apparent porosity≦30％

Cold crushing strength.≧30Mpa
