Abstract

PURPOSE: The above mentioned formed body, having a high anticorrosive property and spalling resisting property, able to carry out uniform bubbling, containing C powder and binder, composed of a specific composition of refractory material as remainder.
CONSTITUTION: This formed body in contained C powder; 4W50% and binder≤ 20% by weight and moreover, on occasion demands, is contained less than 10% of Si containing substance as Si content, producing SiC reacting with C by heating and the remainder is composed of more than one kind of each matter of alumina, magnesia and spinel. Porous plug foundation brick is obtained by kneading and forming the above forming material and coking is carried out by evaporating the volatile matter from the binder by carrying out reduction calcination of the above brick at a high temeperature. Sintering prevention in use is accelerated by obtained formed body for gas blowing. Also, ground metal fin is able to prevent because wettability against molten steel is small.
