Abstract

PURPOSE:To clean a steel and to improve the durability by coating the monolithic refractory consisting of the CaO refractory particle of the main component and the CaO and/or MgO fine powder of <= specified particle diameter. CONSTITUTION:The block for a weir is formed by the MgO tundish weir main body 2 having the surface on which the groove as shown in a figure exists for instance and the coating 1 obtd. by giving and drying the body kneading a CaO monolithic refractory with a proper water amt. on this whole face. And said monolithic refractory is formed by the CaO refractory particle (>=0.1mm particle diameter preferably) composing the main component, i.e., aggregate part and the CaO powder of <=100mu composing a fine powder part, i.e. combination part. This block has a sufficient clean steel effect at its coating layer and some effect at its main body itself, the generation of the crack and breakdown of the main body is hardly caused as well and no peeling off is caused even if a crack is generated.
