硬質(zhì)合金輥環(huán)廣泛應(yīng)用于高速線材軋機的精軋機架，以及部分高速線材軋機的預(yù)精軋機架和棒材軋機的精軋機架。硬質(zhì)合金軋輥的優(yōu)點是硬度高、耐磨性好，單槽軋鋼量可以達到高速鋼軋輥的兩倍。

The cemented carbide roller ring is widely applied to the finishing mill housing of high-speed wire rod mill, as well as the finishing mill for some high speed wire rod mill and the pre finishing mill and bar mill. The biggest advantage of the hard alloy roll is high hardness and good wear resistance, and the amount of single groove rolled steel can reach two times of the high speed steel roll.

不同類型的軋機以及同類型而使用條件不同的軋機，對所用的軋輥性能要求不盡雷同，如方坯和板坯初軋機軋輥要具有好的扭轉(zhuǎn)和彎曲強度、韌性、咬入性、抗熱裂性和熱沖擊性以及耐磨性；而熱帶精軋機架要求軋輥輥面的高硬度、抗壓痕、耐磨、抗剝落和耐熱裂等性能。軋輥是軋機的重要部件，按照軋機類型可分為領(lǐng)帶軋機軋輥、型鋼輪機扎輥和鋼管軋機軋輥三大類。

Different types of rolling mill and the same type and the use of different conditi on properties of roll mill, requirements for not identical, such as billet and slab mill roll with good torsional and bending strength, toughness, bite, thermal cracking resistance and thermal shock resistance and abrasion resistance; tropical finishing stand requirements the roller surface hardness, wear resistance, spalling resistance, indentation resistance and thermal cracking performance.

通常對粗軋輥以強度、抗熱裂為主要要求；小型20輥軋機的工作軋輥重僅 100克左右，而寬厚板軋機的支承輥重量已超過200噸。選用軋輥時首先根據(jù)軋機對軋輥的基本強度要求，選定安全承載的主體材料（各種級別的鑄鐵、鑄鋼或鍛鋼等）。

Usually, the main requirements for rough rolling roll are strength and thermal cracking. The working roll weight of small 20 high mill is only 100 grams, while the weight of backup roll of wide plate mill has exceeded 200 t. When selecting the roll, first, according to the requirements of the mill's basic strength for the roller, we select the main material for safety loading (various grades of cast iron, cast steel or forged steel, etc.).

既避免機械加工，又無補焊熱應(yīng)力熱影響，修正厚度也不受捆綁，一起產(chǎn)品所具有的耐磨性及金屬材料不具備的退讓性，確保修正部位的接觸協(xié)作。

Not only to avoid mechanical processing, but also to weld hot stress and heat, the correction thickness is not bound, and the wear resistance of a product and the non - concession of metal materials are not available, so as to ensure a hundred percent contact and cooperation of the corrected parts.
