軋輥產(chǎn)生彈性壓扁時可能軋制的板厚。在一定軋機上軋制一定的產(chǎn)品時，隨著板帶的逐漸變薄，壓下越來越困難。這是因為應(yīng)用于粗軋機架和精軋機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。當板帶薄至某一限度后，不管如何旋緊壓下螺絲或加大液壓壓下的壓力，不管反復(fù)軋制多少道，由于軋輥產(chǎn)生彈性壓扁而不可能再使產(chǎn)品變薄。這一極限厚度稱為可軋厚度。

The smallest plate thickness may be rolled when the roll produces elastic squash. When a certain product is rolled on a certain rolling mill, with the gradual thinning of the strip, it is becoming more and more difficult to press down. When the strip is thin to a certain limit, no matter how to tighten down the screw or increase the pressure of hydraulic pressure, no matter how many rolls are repeatedly rolled, it is  for the product to become thin due to the elastic flattening of the roll. This limit thickness is called the minimum rolling thickness.

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

修正精度高，涂層厚度從幾微米到幾毫米，可對金屬工件呈現(xiàn)磨損、劃傷、、裂紋、破損變形、硬度降低、損害等缺點進行堆積、封孔、補對等修正功用，只須打磨、拋光，也可進行車、銑、 刨、磨等各類機械加工，以及電鍍等后期加工。

The thickness of the coating is high, and the thickness of the coating is from several microns to a few millimeters. It can be worn, scratched, pinholes, cracks, breakage and deformation, hardness reduction, damage and other shortcomings to accumulate, seal, and compensate for the defects, such as grinding, polishing, milling, milling, grinding and other kinds of mechanical processing, as well as electroplating later processing.
