Wc-Co and Wc-Co-Ni-Cr High Speed rolling mill Tungsten Carbide Roll Rings finishing mill

Tungsten Carbide Roll Rings high speed wire rod mill morgan mill

1. APPLICATION:

Tungsten carbide roll ring is applied to high-speed wire rod mill or Cold rolling ribbed steel bar mill.

Tungsten carbide roll ring possesses good thermal conduction property.Compared with other materials,it is with higher heat-resistance,wear-resistance and strength.

The hardness reduces less under the condition of high temperature.So,It is invented with the ap-pearance of high speed wire rod mill.

With the development and improvement,it is widely applided in the production of high speed wire,bar and

deformed steel bar.
 

The material for our products,there are two series as Wc-Co and Wc-Co-Ni-Cr,which possess the good comprehensive mechanical properties.The bending strength and impact toughness reach 2800 Nmm2 and (4-6)*106J/㎡ respectively.

The hardness and wear resistance is subject to tunsten carbide (WC), while the toughness and strength depend on the binder (Co-Ni-Cr).

At present,the finishing mill is generally composed of 8-10 stands.Because of the big size of fracture surface of rolled part,the collar on the front stands of finishing mill may resist heavy duty and strong impact.

Thus,the high hardness and good thermal fatigue resistance are the primary factors,which are prior to wear-resistance. While there is low load and impact for the rear stands, we shall pay more attention to the wear-resistance and thermal fatigue resistance of roll rings.

This manual describes the grades and properties of our Tunstan carbide roll rings in details, so that it is helpful for you to make choice & operion, eaily.
