不同類型的軋機(jī)以及同類型而使用條件不同的軋機(jī)，對(duì)所用的軋輥性能要求不盡雷同，如方坯和板坯初軋機(jī)軋輥要具有好的扭轉(zhuǎn)和彎曲強(qiáng)度、韌性、咬入性、抗熱裂性和熱沖擊性以及耐磨性；軋輥是軋機(jī)的核心部件，軋輥的使用涉及軋機(jī)使用時(shí)的類型選擇、軋輥的準(zhǔn)備、在軋制過(guò)程中的維修和周期性修整，而這些都全是影響軋機(jī)生產(chǎn)率、產(chǎn)品質(zhì)量和生產(chǎn)經(jīng)濟(jì)性的因素。而熱帶精軋機(jī)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。

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.

弄清軋輥的使用條件以及在同類型軋機(jī)中所用軋輥的失效方式，了解當(dāng)前各種軋輥材質(zhì)的性能和制造工藝，才能較正確地制定該軋機(jī)用輥的技術(shù)條件和選用合適而經(jīng)濟(jì)的軋輥材質(zhì)。

We must know clearly the condition of the roller and the failure way of the roll used in the same type of rolling mill, and understand the performance and manufacturing technology of all kinds of roller material at present, so that we can correctly formulate the technical conditi of the roller and choose the right and economical roller material.

什么是鑄造軋輥，鑄造軋輥主要有哪些種類？

鑄造軋輥是指將冶煉鋼水或熔煉鐵水直接澆注成型這一生產(chǎn)方式制造的軋輥種類。

鑄造軋輥按材質(zhì)又可分為鑄鋼軋輥和鑄鐵軋輥兩類；按制造方法又可分為整體鑄造軋輥和復(fù)合鑄造軋輥兩類。

What are the casting rolls and what are the main types of casting rolls?

The casting roller refers to the type of rolls produced by direct casting of molten steel or molten iron.

The casting roll can be divided into two types: cast steel roll and cast iron roll according to material quality. According to the manufacturing method, it can also be divided into two types: integral casting roll and compound casting roll.

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.
