The CQ300 heating insulation riser sleeve has the advantages of light weight, accurate size, low thermal conductivity, high bending strength, high fire resistance, and not easy to absorb moisture. It is widely used in the shrinkage of cast iron and steel castings. This riser sleeve can be equipped with easy to cut pieces, and the residue after casting can be hammered off, further reducing cleaning costs such as cutting and polishing.

efficacy

1. Effectively solve defects such as shrinkage porosity and porosity in castings.

2. Significantly reduce defects such as slag inclusion and porosity in castings.

3. Effectively improving the production rate of casting processes and enhancing economic benefits.

4. Reduce the workload of cleaning and welding repair for the riser sleeve.

characteristic

1. The riser sleeve has high strength and is not easily damaged during design.

2. High heating efficiency, good insulation effect, and long solidification time.

3. The product range is complete and suitable for different casting production line usage conditions.

4. The effective modulus is high, and using a small-sized CQ300 riser sleeve can replace a large sand mold riser sleeve.
