Abstract
The present invention is directed to raw mix flux for the continuous casting of steel wherein the flux composition consists of a mixture of ceramic raw material having the following theoretical analysis based on the composition formed on melting the raw materials: K.sub.2 O: 0 to 5 percent by weight Na.sub.2 O: 20 to 35 percent by weight CaO: 5 to 25 percent by weight MgO: 0 to 1 percent by weight Al.sub.2 O.sub.3 : 3 to 10 percent by weight B.sub.2 O.sub.3 : 15 to 30 percent by weight SiO.sub.2 : 5 to 20 percent by weight F: 10 to 25 percent by weight Fe.sub.2 O.sub.3 : 0 to 1 percent by weight and wherein the percentages of said ingredients total 100 percent by weight.
