Yantai ETDZ Dongxing Industrial Co., Ltd is a professional cemented carbide roller manufacturer controlled by Yantai Shougang Dongxing Group Co., Ltd and shared by the staffs.

Yantai ETDZ Dongxing Industrial Co., Ltd now is equipped with the cemented carbide rollers production technology and facilities which are in the highest level in China and adopts international prevailing treatment techniques in production such as cold press molding, vacuum sintering, heat isostatic press (HIP).

Yantai ETDZ Dongxing Industrial Co., Ltd has achieved annual production capacity of tungsten carbide roll-ring of 240 tons in 2008. With constant expansion and reconstruction in recent years, the Company has further increased the types and production capacity of cemented carbide roller, and possessed rich experiences in producing cemented carbide rollers for MORGAN series, ASHLLOW series and DANIELI series plants.

The Company has such professional production equipment as imported grooving grinders, vacuum sintering furnaces, heat isostatic presser (HIP), and NDT testers which is the most advanced post-treatment equipment for cemented carbide roller in the world up to now.

The Company has self-developed the new-type cemented carbide rollers containing such elements as Ni-Cr that greatly improves their wear resistance, impact resistance and corrosion resistance, rivaling foreign products in terms of performance indices. We equip with the first pollution-free full-closed production line in China and reinforce the powder detection and mechanic performance tests.
