Rotary submersible tuyere for bucket refining of fusion PP163
The development is intended for the refinement of metal melts in buckets by injecting gas and /or gas - jet streams into the baths, ensuring a rational distribution of gas and solid reagents along the volume of the bath.
Such tuyeres can be equipped with converter and casting shops of metallurgical enterprises of Ukraine and other countries.
The state of readiness of development
A laboratory sample was made, high - temperature experimental and laboratory tests were carried out, the expected characteristics.
Key features, the essence of the development
The principle of uniform distribution of mixing or refining gas and solid powdery reagents on the bucket bath with the intensification of mixing and elimination of stagnant zones has been used. Injection of dispersed magnesium in the melted pig iron to desulfurize with an increase in specific intensity and degree of desulphurisation by 24 and 18% respectively, reducing the consumption of magnesium by dissolution by 30% and the length of treatment by 25% . The submersible multistage livestock instills gas and / or gas - gas jets deep into metal melts in a ladle with a rotational mechanism around the axle, with a speed of rotation from 0 to 200 rpm. The possibility of reducing the "free side" in the ladle to 300 - 350 mm is realized.
