PREVENTION METHOD OF PULVERIZATION OF CR CONTAINING ALLOY STEEL REFINING SLAG

摘要

PROBLEM TO BE SOLVED: To provide a dense slag efficiently by completely preventing pulverization of Cr containing alloy steel refining slag in melt condition.;SOLUTION: In this prevention method of pulverization of Cr containing alloy steel refining slag, the Cr containing alloy steel refining slag in melt condition is spread on a die made of a metal in a thickness not greater than 25 mm, then after keeping it for a time not shorter than T(s), which is defined by the formula: T=0.25×t² in relation to the thickness t(mm), then it is cooled to solidify and released from the die and cooled.;COPYRIGHT: (C)2005,JPO&NCIPI
