The tuyere made by vaccum casting has high copper purity and good thermal conductivity. The tuyere's front part made by forging technology has high property of resisting hot fatigue. The grain in it is compact and the organization is high-density.
Characteristics:
The tuyere made by vacuum casting has high copper purity and good thermal conductivity.
There are scarcely and defects in the castings like gas hole, loose, blowhole.
By optimal designing the inside structure of the water passage, the tuyere has smaller fluid drag and good cooling effect.
The tuyere's front part made by forging technology has high property of resisting hot fatigue. 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:>=94%IACS
Pressure test: Test hydraulically at 1.5MPa for minimum 30mins. No leakage or sweating permitted.
