A FORMED BODY COMPRISING LOW SULFUR CONTENT, MANUFACTURE METHOD OF THE FORMED BODY ; AND ADDITIVE FOR PROTECTING FURNACE WALL COMPRISING THE FORMED BODY

摘要

PURPOSE: A molded body, a method for manufacturing the same, and a furnace wall protecting additive are provided to separate or eliminate powder, in which the diameter thereof is smaller than 1mm, containing plenty of sulfur components from the composite oxide powder of calcium and magnesium. CONSTITUTION: A molded body includes the composite oxide powder of calcium and magnesium, which is represented by CaO·MgO, and a binder. The sulfur content of the molded boy is 0.050 weight% or less. The diameter of the composite oxide powder is 1mm or more. The binder is one selected from a group including dextrin, molasse, and Pregelatinized starch. The molded boy includes 0.5-30 parts by weight of the binder, based on the 100.0 of the composite oxide powder. The composite oxide powder, in which the diameter thereof is smaller than 1mm, is eliminated.
