The annual production capacity is 9,000 tons.

(2) Our Wirl & Bar Mill Roll factory specially produces and supplies work rolls and back-up roll for bar mill, wire mill, small/mediate-sized section mill, narrow and medium-wide strip mill. The annual production capacity is 26,000 tons.

(3) Our Special Roll factory specially produces and supplies rolls and roll rings for seamless tube mills, roll rings and shaft for H-beam and universal  structural mills, rolls for large-sized high frequency straight welding mills (diameter over 508) etc. The annual capacity is 15,000 tons.

(4) Our Equipment Manufacturing factory specially produces and supplies all types of bloom, slab, special section blank for continuous casting machine, coke oven armature, complete sets of coke dry quenching equipment, heat treatment equipment for steel plate surface, cold rolling decoiler, wind power spare parts etc. The annual production capacity is 80,000 tons. 


Technical Supports

The factories of CNBM invested 2.3 billion RMB for large-scale technical innovation during the “Eleventh Five -Year Plan”. Our company has completed equipment and technology upgrade transformation at the end of 2008, which was concentrated on three projects, production line of centrifugal casting rolls for hot strip and plate mill, forged roll for cold/hot strip mill, national class technology center and roll material lab. Through upgrade transformation, the following targets have been achieved:

(1) It becomes the world’s biggest specialized mill roll maker with the largest production scale, the most complete specifications of products and the most extensive coverage of various rolls used on rolling mill. 

(2) The technology of equipments has reached international leading level.

(3) “Mechanization, automation, intellectualization, digitization” of equipments obviously improve the quality control ability.

(4) New types of research instruments improve the R&D capacity of products.
