钢材预处理质量的优劣已经对生产工艺和产品质量产生重要影响，它已成为金属工业生产必不可少的工艺过程。针对国内钢材予处理工艺的现状，青岛三锐机械有限公司广泛吸收国外先进技术，发挥自己的技术专长，研制、开发了具有世界先进水平、并适合我国国情的辊道连续钢材预处理生产线系列产品。该系列机采用多台世界上最先进的单园盘曲线叶片高效抛丸器，抛射出的高速密集的弹丸，打击在工件的表面上，使工件表面上的锈蚀层及其污物迅速脱落，获得一定粗糙度的光洁表面，提高了漆膜与材料表面的附着力，提高了材料的抗疲劳强度和抗腐蚀能力。辊道连续钢材预处理生产线，缩小了我国钢材预处理设备与国际先进水平的差距。

它适用于钢板、型钢的表面除锈、涂漆(即前处理)，并可对长形结构件进行抛丸除锈(即后处理)。是船舶、汽车、机车车辆、航空、机械、桥梁、海上石油钻井平台、港口码头设施、集装箱、锅炉、冶金等制造行业的理想装备。

The quality of metal surface treatment influences production technology and manufacture quality. It has been the indispensible process in metal production. Probing to the present situation of metal treatment technology in China, extensily absorbing the foreign advanced technologies and playing itself special skills, Qingdao Foundry Machinery Group Company developed a series of world advanced Continuous Roller Conveyor Type Shot Blasting Machines and Steel Precondition Lines. This series equipment use a number of world most advanced single-disc blast wheels of high efficiency. They project abrasive at high velocity onto workpiece surfaces to quickly remove the rust, scales and dirty on the surfaces. The workpiece after treated will obtain a clean with certain roughness surface so as to increase painting adhesive ability. The fatigue and corrosion ability of it are increased.
