1,high-pressure grinding wheel for steel plant

 

The products are used for operations ranging from defects-removing grinding of steel blooms / slabs, ingots and sheets all the way to partial / full oxidized 

surface grinding and conditioning of products in steel industry. Their features of heavy duties, 

high removal ratios, and high cutting efficiencies lead to less operator intensities, better environmental

 conditions, and improved after-ground surface qualities of the workpieces.

 2,Heavy Duty Steel Bloom / Slab Hot Conditioning Wheels

 The products are adopted in online grinding of blooms / slabs during hot rolling at relatively high 

working temperatures. The wheels are specifically developed for state-of-the-

art technology of hot grindings of steel blooms / slabs. Compared with cold grinding wheels this 

technology takes advantage of thermal energy of workpieces, leads to higher productivities, gets

 rid of surface cracking on workpieces, and obtains improved surface polish.
