The core part of the slag-stopping dispatching machine is a manipulator which like arms . When it can elongate more than 6m , the manipulator can hold on the slag-stopping plug about 30~45kg at a radiation environment as 1600.C . While the converter titling reach to the engaged angle , follow the converters location . At the appropriate when come out steel , it can insert the slag-stopping bar to the steel-tapping hole . Then it lose up the manipulator , and the slag- stopping plug fixed at the steel-tapping hole which float the interface between molten steel and steel slag , consequently it finished the technological procedure . The slag-stopping dispatching machine set at the back of the converter platform . So our corporation made a careful consideration at the specification of equipments . Just change a little in prototype machines , then it can be applicable to the converter that the level is 30T up to 300T .
