TUBE, EQUIPMENT AND METHOD FOR MEASUREMENT OF FLUIDITY OF MOLTEN METAL

摘要

A pipe, equipment and a method for measurement of fluidity of molten metal are provided to automate the fluidity measuring process by moving up a molten metal crucible so that the measurement pipe is immerged in the molten metal, instead of moving the measurement pipe. A pipe for measurement of fluidity of molten metal comprises a main body(610) of long pipe shape, a mold holder(620) for joining the halves of the main body and fixing them, vacuum grease(630) coated on the surfaces of the halves in order to prevent the inflow of air, and a vacuum coupler(650) installed at the location corresponding to the inlet end of the main body. As vacuum is applied through the other end of the vacuum coupler the molten metal flows in the inlet end of the main body. The main body, the mold holder, the vacuum grease, and the inlet end are made of materials not dissolved at the heating temperature of the molten metal.
