Product Description

Characteristics:
The tuyere made by vacuum casting has high copper purity and good thermal conductivity.
There are scarcely any defects in the casting like gas hole, loose, blowhole.
After optimal designing of the inside structure of the water resistance and good cooling effect.
The nose of tuyere made b forging technology has high property of hot fatigue resistance. The grain in it is compact and the organization is high-density.

Technical parameter:
Chemical Composition: Cu≥99.93%    O≤30ppm    H≤1.0ppm
Electric conductivity: σ≥94%IACS
Pressure test: Test hydraulically at 1.5Mpa for minimum 30 mins. No leakage or sweating permitted.

Influence to the tuyere's service life by oxygen content:
The content of oxygen in the vacuum casting tuyere is 30ppm maximum, while the ordinary casting tuyere is 200ppm minimum. Oxygen existing in the grain boundary.
In the form of CuO can cause the castings to hydrogen embrittle, which we call the surface cracking by naked eye, finally leading the tuyere to early failure.
