Simple and adjustable inclined air outlet clamp
The double chamber blast furnace tuyere developed by our factory is a copper piece. The shape is shown in the figure (dotted line), which is composed of two round tables combined at a certain angle. The large end side is required to be machined, and the front end concave ball SR is required to be processed, the surface roughness is R_a1.6, and the inside is a cavity. Because the rear end face and the front end face are inclined by 5 ° ~ 15 °, it is not easy to install during processing, often the clip is not strong, and it is easy to be dangerous, which brings great difficulties to production.
