Abstract

PURPOSE: To obtain smooth, uniform surface finish with higher efficiency and less dirt at pressurized dry injection blasting method by adopting air-crushed slags produced in a Bessemer convertor as a grinding material.
CONSTITUTION: Air-curshed convertor slags used for a grinding material are made from slags in a Bessemer convertor produced during steel making process. The slags are spherical with a dismeter ranging from 0.3MM to 2.5MM, and they are blasted to the surface of thick steel plates at a pressure of between 5 and 10kg/cm2 from nozzles having diameters of 4 to 8 MM which are attached to a pressurized injection sand blasting machine. Thus longer life of the nozzles and more uniform surface finish are obtained with less dirt scattering.
