圣霖國際軋輥優(yōu)選商家

軋輥產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品時，隨著板帶的逐漸變薄，壓下越來越困難。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，不管反復軋制多少道，由于軋輥產生彈性壓扁而不可能再使產品變薄。硬質合金軋輥的優(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。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.

（1）堆焊前需先將軋輥輥身表面的疲勞層或缺陷，尤其是裂紋必須徹底清除；  

（2）在堆焊時，為了防止裂紋的產生，必須先加工軋輥輥身預熱，預熱溫度根據軋輥輥及堆焊材料而定。

(1) before welding, the fatigue layer or defect of the roller body surface must be first removed, especially the crack must be thoroughly removed.

(2) in the process of surfacing, in order to prevent cracks, the roller body must be pre heated, and the preheating temperature should be determined according to roll rolls and surfacing materials.

軋機布置和道次設計  

機架在生產線的位置以及道次設計對軋輥的選擇有很大影響。根據機架位置，軋輥的受力方式和性能可以有很大變化。這是因為應用于粗軋機架和精軋機架的軋輥有非常不同的受力方式，從而導致軋輥性能有預期的改變.

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.
