Tungsten Carbide Roll Rings high speed wire rod mill morgan 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.
TR & YGR (Wo+Ni+Cr-binder) , YGH series (Wo-binder)
|TR06||It possesses the highest hardness and best wear-resistance among all the varieties of tungsten carbide toll rings, thus used for the rolling of common wire and hard wire on the last stands of high-speed wire rod finishing mill.|
|TR08||It possesses better wear-resistance and moderate impact-resistance with the hardness second to TR06 among all the varieties, thus used at the last two stands of high-speed wire rod finishing mill .|
|TR10||It possesses the moderate wear-resistance and impact-resistance and good versatility, thus used at the third-fourth stands from the bottom of high-speed wire rod finishing mill or all the stands .|
|TR12||Because of the best versatility, it is used at the front stands of finishing mill and rear stands of common rolling mill.|
|TR14||It is usually used at the first or second of finishing mill, and also applies to the stands of rolling machine with low speed and accuracy and varied technology.|
|YGH20||With high hardness. it is used for the rolling of common wire and hard wire at the last two stands of finishing mill.|
|YGH25||With good wear-resistance and moderate impact-resistance, it is used at the last two stands of finishing mill.|
|YGH30||With moderate wear-resistance and impact-resistance and good versatility, it is used at the last four stands of finishing mill or all the stands.|
