Abstract
Increase in taphole length can be achieved if the taphole mud as injec ted stay at around the in-furnace; taphole opening and sinters there. This can only be possible if the coke column and the mud mass make a g ood contact at the in-furnace taphole opening. Theoretical calculation of the penetration depth of the coke column into the hearth showed th at the degree of contact of the coke column with the mud mass may chan ge in normal operation of blast furnace. The degree of the contact can be controlled by controlling the raceway depth of tuyeres above the t aphole concerned.
