摘要： PURPOSE: To prevent the development of flaw below the surface layer part of the steel slab newly on the surface part, at the time of partially cleaning the remaining flaw after hot-scarfing the whole surface of a steel slab. CONSTITUTION: After hot-scarfing (n4) the whole surface of the steel slab, the tangible flaw is detected (n5), and when the ratio R of the area S1 to clean this detected flaw to the whole area is >= about 30%, again the hot-scarfing is executed to the whole surface. In the case of being less than this value, abrasive water jet as the mixed material of grinding grains and liquid is injected to execute a minite cleaning (n9). After grinding with the abrasive water jet in such a way, the steel slab is rolled (n10) without detecting the remaining flaw.

摘要： PURPOSE:To shorten a time required from inspection to the end of grinding by setting a grinding condition in accordance with the from of a discriminated surface flaw and controlling the grinding when the surface flaw of a metal plate is ground and removed by an abrasive water jet. CONSTITUTION:When surface flaws of a metal plate is ground and removed by using an abrasive water jet for cutting a work piece by naking a polishing material to follow high pressure jet water flow and forcing the polishing material member to collide with the work piece, the surface flaws are classified into crack flaws and pinhole flaws and the surface flaws of the pinhole flaws are further classified into a dispersion type and a concentrated type. The dispersion type pinholes are ground separately by setting depth index according to their sizes. The concentrated type pinholes A are controlled in their grinding by finding an inner area formed by linking respective peripheral tangent lines of a plurality of pinholes and finding a depth from the max. size of diameters. With regard to any crack flaw, grinding is controlled by finding out a predictive depth H according to a depth conversion index from a length L1 of the crack flaw.
