Abstract

Magnesium is conveyed from a feeder by compressed gas into molten cast iron at the rate of 2 - 4.5 g/s-t through a tuyere with an evaporator, immersed into molten cast iron. The tuyere is made in the form of a metal pipe with a flaring-out nozzle which is provided with side holes, serves as an evaporator and is covered with refractory lining, the relation of the tuyere evaporator inside diameter in the section passing through the upper edge of the side holes to the evaporator height from the upper edge of the side holes to the point where the tuyere pipe opens into the evaporator being from 0.3 to 0.8.
