Roll repair

Product description

Roll repair technology
Roll as a key spare parts of the mill consumption in the rolling process is very large, and welding technology is the manufacture and maintenance of machinery manufacturing industry is an important means in recent years has been widely used in the repair of roll. When the roll to the end-of-life limit, after the roll after the welding repair with low cost, long life, and use of effective features.
The roll repair before and after contrast

 

The company introduced assimilate the advanced welding repair materials and technology, innovation and a set of equipment and technology for own requirements. Large-scale cold rolling mill and supporting roller surfacing technology development and production.
After several years of accumulation and innovation, the company has successfully repaired the different materials including gray iron, ductile iron, carbon steel, alloy steel, alloy forged steel, high carbon semi-steel rolls, and initially formed a complete set of , distinctive features from the diagnosis, repair, process control, material selection, process design, failure analysis systems theory and procedures.
Roll Failure Analysis

  The Company on the basis of the research and development of a variety of materials roll repair technology, and constantly open up new areas of the market, and successfully main piston hydraulic press, the master cylinder, grease grinding roller, glass conveying roller, synthetic fabrics embossing rollers, cement plantspecial products of the milling roller gear shaft repair. Increased by 5 times the performance and life of conveying rollers, the technology has reached world advanced level.
Advanced equipment, ensuring a reliable product quality

 Wait for the delivery roll

 Roll mill key spare parts consumed in large quantities in the rolling process. Roll directly affects the quality of the work efficiency of the mill, the quality and yield of the rolled product, the roll consumption. China's annual output of steel has more than 7 million tons, consumption roll value of 200 billion yuan. Surfacing restoration of the old roll to roll life has become an important measure of rolling enterprises to reduce costs and improve efficiency, but also in line with our energy saving, clean production, the basic national policy of recycling economy.
Surfacing Machinery Manufacturing IDM important manufacturing and maintenance means widely used in the repair of rolls. When the roll to the end-of-life limit, welding repair welding repair roll with low cost, long life, and use of effective features to promote the recycling economy achieved remarkable success by rolling enterprises generally welcome.
