摘要： A grinding method is provided in which abrasive is projected onto a steel product through a nozzle to perform grinding thereon such as in a continuous casting process or in a subsequent process, wherein high-pressure water jet mixed with the abrasive is projected onto the surface of the steel product to grind defects on the surface, etc. thereof. A grinding system for executing this grinding method is also provided, the system including supply sources of high-pressure liquid and abrasive, a nozzle device connected with these supply sources, an abrasive recovery device for recovering the used abrasive as needed and restoring the same to the supply sources, and combined detection systems.

摘要： A continuous caster mold has a water-cooled inner wall of copper or a copper alloy that is thoroughly covered with pieces of ceramics. A continuous casting process, which uses a mold whose inner wall of copper or a copper alloy is lined with ceramics having resistance to wear, heat and thermal shock, heat conductivity and lubricating property, with the thickness of the ceramics lining varied either stepwise or continuously in the casting direction. The molten metal, which progressively solidifies as its heat is extracted, is withdrawn by taking advantage of the solid lubrication provided by the ceramics lining. The thickness of the lining is varied to prevent the formation of air gaps between the surface of the lining and the solidifying shell and cool the steel being cast according to the desired pattern, and/or to start solidification of the molten metal below the molten metal surface level.
