OF HIGH-ALUMINA SLIDE GATE PLATES

tion of the processes in the iron and steel industry is the production of high quality metal, which to a large degree is determined by the teeming conditions. The appearance of leaks of metal in teeming of steel from ladles with slide gates unavoidably leads to poorer ingot quality in top teeming into molds. In this case it is difficult to overrate the value of reliable operation of the slide gate, the final link in the process of teeming steel from ladles. With observation of the temperature conditions of the metal being teemed and of the method of preparation of the ladles and assembly of the slide gates one of the reasons for breakdowns in the teeming conditions is failure of slide plates.
