On maximizing oxygen converters lining life

Guniting and residual slag spraying in an oxygen converter, gas-cooled tuyeres of several patterns have been offered. The calculations to reduce oxygen consumption required for lancing, as well as to simplify the tuyere design have been made. Systems of differential and integral equations have been used to calculate such factors and physical actions as powder concentration, duct length and power influence, suspension of matter in gas velocity relation over the area of high temperatures. Experiments have shown that substitution of the gas-cooled tuyere for the water-cooled tuyere converts the tuyere into a heat exchanger making it possible to use the energy formerly lost as a result of dissipative losses. The results of this work can be used to improve existing and new advanced technologies that reduce emissions into the environment
