Researches On The Key Techniques Of The All-Solid Pulse Cascading YAG Laser Texturing Equipment

Presently, ordinary cold-strip steels could not meet the requirements for cold-stripsteels applied in the areas such as automobile industry and home appliance industry, etc,which is developing so fast. Meanwhile, demands for the surface–textured cold-rolledsheets, referring to the cold-rolled sheets whose surfaces are textured, are growing due totheir great advantages like even surface roughness without scratches and strips and goodshapes.Previous surface texturing technique could not satisfy the manufacturing enterpriseswhose production requirements are high efficiency, high quality and high roughness withlow cost. Under the circumstances, we develop a new all-solid pulse cascading YAG lasertexturing equipment. This texturing equipment is constituted of the laser, a texturingmachine, control system and cooling system. The digital control system is speciallydesigned for the equipment, and could help to accomplish the texturing processing workonly with a button click, which meets the requirements of high accuracy and automation.This thesis introduces the design philosophy of the pulse cascading laser texturingequipment, analyses the advantages of this equipment and discusses the laser texturingtechnology. The idea that the laser and texturing machine should be integrated in the pulsecascading laser texturing equipment is firstly proposed after the researches on the texturedrollers and textured sheets are conducted with our laser texturing equipment. The lasertexturing equipment wins high praise from our customers and fulfills their demands ofproducing cold-rolled sheets with high quality.
