硬質(zhì)合金軋輥是在硬質(zhì)合金刀具的基礎(chǔ)上發(fā)展而來(lái)的,硬質(zhì)合金是采用堅(jiān)硬的碳化鎢顆粒硬質(zhì)相與鎳、鈷等黏結(jié)相金屬燒結(jié)而成。硬質(zhì)合金的性能取決于碳化鎢顆粒尺寸的大小和黏結(jié)相金屬含量的多少,當(dāng)黏結(jié)相金屬中含有一定量的鎳和鉻時(shí),不僅會(huì)大大提高軋輥的抗熱疲勞性能。硬質(zhì)合金的性能取決于碳化鎢顆粒尺寸的大小和黏結(jié)相金屬含量的多少,當(dāng)黏結(jié)相金屬中含有一定量的鎳和鉻時(shí),不僅會(huì)大大提高軋輥的抗熱疲勞性能。

Cemented carbide rolls are developed on the basis of cemented carbide tools. Cemented carbide is made of hard tungsten carbide particles and hard phase sintered together with nickel and cobalt bonded phases. The properties of cemented carbide depend on the size of tungsten carbide particle and the content of bonding phase metal. When the amount of nickel and chromium in the bonding phase contains metal, it will not only greatly improve the thermal fatigue resistance of the roller.
軋輥具有粘著力,優(yōu)異的抗壓強(qiáng)度、耐磨性和抗腐蝕性等歸納功用,選用高分子復(fù)合材料在傳動(dòng)部位磨損規(guī)范相對(duì)較小的狀況下可以現(xiàn)場(chǎng)免拆開(kāi)修正。
The roller has super strong adhesive force, excellent compressive strength, wear resistance and corrosion resistance, and so on. The polymer material can be free from dismantling in the condition that the wear standard of the transmission part is relatively small.
冷軋輥在工作過(guò)程中要承受很大的軋制應(yīng)力,加上軋件的焊縫、夾雜、邊裂等問(wèn)題,容易導(dǎo)致瞬間高溫,使工作輥受到強(qiáng)烈熱沖擊,造成裂紋、粘輥、剝落甚至報(bào)廢。同時(shí),不同的軋機(jī)所選擇的軋輥也是不相同的,需要根據(jù)生產(chǎn)要求選擇軋輥。因此,冷軋輥要有抵抗因彎曲應(yīng)力、扭轉(zhuǎn)應(yīng)力、剪切應(yīng)力引起的開(kāi)裂和剝落的能力,同時(shí)也要有高的耐磨性。


Cold roll must bear a lot of rolling stress in the working process, add the weld, inclusion and edge crack of the rolled piece, which can easily lead to instantaneous high temperature, so that the work roll is subjected to strong heat shock, which causes crack, roll, peeling and even scrap. Therefore, the cold roller must resist the ability of cracking and spalling caused by bending stress, torsional stress and shearing stress, and also has high wear resistance.
