Cleaning of steel plate surface by laser irradiation
专利汇可以提供Cleaning of steel plate surface by laser irradiation专利检索，专利查询，专利分析的服务。并且PURPOSE: To miniaturize cleaning line as well as reduce installation cost and expenditures by removing organics, etc., effectively by the procedure in which a CO
2 laser high-power absorbent is provided on the surface of steel plate and then CO
2 laser is irradiated onto the surface.
CONSTITUTION: In the cleaning of rolling lubricant, etc., adhered to the surface of a cold-rolled steel plate, galvanized thin steel plate, etc., a CO
2 laser high-power absorbent, e.g., a compound with C-O, C-N, and N-O bonds, a compound with P-O-C bond and S-O bond, a C-C-M bond type compound (M is Si, P, Cl, Sn, Al, etc.), a compound with CH
2 =CHR, R-CH=CH
2 (trans type and its conjugated), and CH=CH
2 groups, etc., is beforehand added to organics, e.g., lubricant, etc., on the surface of steel plate, and then CO
2 laser is irradiated onto the surface. Thus, the organics can be evaporated and removed instantaneously and therefore large cleaning space and cleaning agent, as used in the conventional methods, can be made unnecessary.
