What is cold rolling and hot rolling?

Leave a Comment / News /

Rolling below recrystallization temperature is called cold rolling. Hot-rolled coils are usually used as raw materials for cold rolling. After removing oxide scales by pickling, the products are rolled coils. The cold work hardening caused by continuous cold deformation makes the strength, hardness and toughness index of rolled coils increase, so the stamping performance will deteriorate and can only be used for parts with simple deformation.

Relationship between Daily Working Efficiency of Rolling Mill and Ambient Humidity and Temperature

News /

It has been proved by practice that environmental factors are also included in many factors affecting the daily work efficiency of the rolling mill, mainly the humidity and temperature of the environment. Therefore, in order to improve the working efficiency of the rolling mill, the narrow outlet of the heating furnace has strict requirements on humidity. In the case of no tapping, closing the furnace door can reduce air consumption and heat transfer, and reduce the cost of coal or gas.

Factors Affecting Service Life of Rolling Mill

News /

In the operation and use of rolling mill equipment, the higher the working temperature of the mechanical equipment, the lower the value of load capacity, the shorter the service life of bearing. The relationship between the hardness of bearing material and the service life of bearing, the influence of the hardness of bearing working surface material on the service life of bearing, mainly reflected in the reduction of the rated dynamic load value of bearing.

Brief Introduction of Rolling Mill

News /

According to the professional rolling mill manufacturers, generally speaking, the rolling mill equipment is a kind of equipment that can complete the metal rolling process, that is, the equipment to complete the whole process of rolling production, including the main equipment, auxiliary equipment, lifting transportation equipment and auxiliary equipment. However, in actual production, the rolling mill only refers to the main equipment.

Rolling Mill Adjustment before Rolling

News /

Before the rolling mill is used, the roll shape should be adjusted according to the size of the finished products, the plate type should be controlled, and the rolls should be supported; and the fixed position of the rolls in the rolling mill should be maintained. The work load of the roll bearing is heavy and varies greatly, so the friction coefficient of the bearing is required to be small. After determining the product rolled by the mill, the line speed of the rolling mill can be basically determined. The hardness of the raw materials is measurable. The rolling stock of the rolling mill is determined by changing the plastic deformation size.
