硬質(zhì)合金輥環(huán)廣泛應(yīng)用于高速線材軋機(jī)的精軋機(jī)架，以及部分高速線材軋機(jī)的預(yù)精軋機(jī)架和棒材軋機(jī)的精軋機(jī)架。硬質(zhì)合金軋輥的優(yōu)點(diǎn)是硬度高、耐磨性好，單槽軋鋼量可以達(dá)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.

19世紀(jì)下半葉歐洲煉鋼技術(shù)的進(jìn)步要求軋制更大噸位的鋼錠，無(wú)論是灰鑄鐵或冷硬鑄鐵軋輥的強(qiáng)度均已不能滿足要求。含碳量為0.4%～0.6%普通鑄鋼軋輥相應(yīng)誕生。重型鍛壓設(shè)備的出現(xiàn)更使這種成分的鍛造軋輥的強(qiáng)韌性得到進(jìn)一步提高。

In the second half of the nineteenth Century, the progress of steelmaking technology in Europe requires larger tonnage steel ingots to be rolled. Neither the strength of gray iron or chilled cast iron rolls can meet the requirements. The ordinary cast steel roll with a carbon content of 0.4% to 0.6% is born accordingly. The emergence of heavy forging equipment makes the strength and toughness of the forging roll of this component further improved.

線材軋機(jī)擁有粗軋機(jī)架和與小型型材軋機(jī)類似的中間機(jī)架。與兩線軋制的小型型材軋機(jī)相比，這些軋機(jī)一般被設(shè)計(jì)成可以進(jìn)行高達(dá)4線的同時(shí)軋制的切分軋制。然而，目前的發(fā)展趨勢(shì)是采用單線的高速軋制。

The wire mill has a roughing mill stand and an intermediate rack similar to a small section mill. Compared with the two section rolling mill, these mills are generally designed for rolling up to 4 lines at the same time. However, the current development trend is single line high-speed rolling.

軋機(jī)布置和道次設(shè)計(jì)  

機(jī)架在生產(chǎn)線的位置以及道次設(shè)計(jì)對(duì)軋輥的選擇有很大影響。根據(jù)機(jī)架位置，軋輥的受力方式和性能可以有很大變化。這是因?yàn)閼?yīng)用于粗軋機(jī)架和精軋機(jī)架的軋輥有非常不同的受力方式，從而導(dǎo)致軋輥性能有預(yù)期的改變.

Rolling mill layout and pass design

The of the rack in the production line and the design of the pass have great influence on the choice of the roll. According to the  of the frame, the force and performance of the roller can be greatly changed. This ibecause the rolls used in roughing mill stand and finishing mill stand have very different forces, resulting in expected changes in roll performance.
