Cast steel cooling stave

1. The metallurgical bonding rate of water pipe and cooling stave wall is greater than 95%

The cast steel cooling stave produced by patented technology with independent intellectual property rights can reliably realize the metallurgical combination between the steel pipe and the cooling stave body. Through special treatment of steel pipes and other special process measures, while ensuring that the steel pipes are not melted through and the inside of the steel pipes are not oxidized, it also ensures that the steel pipes and the cooling stave body have a reliable metallurgical combination, so that the cast steel cooling staves The thermal conductivity is greatly improved, and the service life is greatly extended. Under normal use, the service life can reach more than 15 years.

2. The inner wall of the water pipe is smooth without secondary oxidation

The special process is used for casting, and there is no oxidation on the inner wall of the water pipe. It can be seen from the dissected section of the cooling wall that the inner wall is very smooth.

3. The cooling water pipe has a high ball penetration rate and a small amount of steel pipe wall thickness reduction

The steel pipe simmering bend is made by cold simmering with an electric hydraulic pipe simmering machine. The "U" water pipe cold simmered by the electric hydraulic pipe simmering machine can pass through wooden balls with a diameter of more than 80% of the inner hole of the water pipe, which is higher than the national 76% pass ball standard, and the water flow is large, so that the cooling wall has higher cooling Strength: The wall thickness reduction of the water pipe is less than 15%, which is better than the national standard of less than 18%, and the service life of the water pipe is longer.
