SLAG-TREATING AGENT

PURPOSE:To accomplish improvement of the working atmosphere and prevent the production of yellow turbid water, by forming a coarsely crushed glass product which is prepared by formulating raw materials each containing a substance with boron as the active component followed by heating and melting the resultant formulations, then cooling and crushing. CONSTITUTION:The objective slag-treating agent i.e. a coarsely crushed product can be prepared by formulating raw materials having boron as the active component such as alkali metal borates, alkaline earth metal borates, borosilicates, alkali metal borosilicates and alkaline earth metal borosilicates, heating, melting followed by cooling and crushing the resultant mass. This product has such a granular size distribution as to contain >=90wt.% of the granules with the size ranging from 1-50mm, and gives a melting point of
