What are the Failures of the Rolling Mill in Slitting Rolling?

In the slitting rolling of the rolling mill process, various bad phenomena often occur because of the misoperation, which directly affects the quality of the whole piece. Therefore, the corresponding preventive measures should be taken before rolling to ensure that the quality of the tied parts produced is the best.

During the whole rolling process, when the fastener leaks out in the high-temperature zone, it is very prone to burr. If it is in contact with the fastener or the temperature rises too fast, there will be the defect of sticking steel. At this time, if the tie piece and its contact, then there will certainly be a very serious situation of sticking steel. Now that the problem of failure has been listed, how should we prevent and solve it?

1. Strengthen the cooling of the discharging tool of the rolling mill so as to avoid sticking steel to the fastener due to high temperature.

2. Reduce the burr of the slitting box in slitting rolling and prevent the leakage of tied parts in the high-temperature area.

3. Periodically check the roll gap of the roll and the value of the roll gap of the slitting wheel, so as to effectively avoid the occurrence of sticking steel.

Factors of Slowness of Cold Rolling Mill

For the manufacturing of rolling mills, no matter what kind of machinery and equipment, the speed of production is very important, so the speed of cold rolling mills is also the same, if there is no speed in the entire production process Then, the production of the product will definitely lag behind, which will have a very serious impact on the enterprise, mainly including economic impact. What factors will directly affect the low speed of the cold rolling mill?


The first is the influence of the material: because there is friction between the rolled material and the work roll in the cold rolling mill, then the speed will also have a corresponding effect, so work in such situations At the time, the amount of lubricating oil will also increase, and it will cause changes in the mode of lubricating oil.


Second, the impact of the cold rolling mill itself: if the cold rolling mill is adjusted faster in mechanical rolling speed, then a larger number of roll necks will appear in the bearing, which will also seriously affect The movement of the roll.

In the process of rolling mill operation, the cooling water will directly cause the screw nut to rust and increase its friction, mainly because the working environment is relatively poor, reducing the service life of the screw nut. Shortening, in order to effectively ensure the transmission accuracy of the screw nut in the reverse direction, and the processing accuracy of the screw nut, the best way is to improve the cooling and lubrication of the rolling mill and add a dust cover to the screw nut. This can achieve the effect of waterproof and breathable.

Continuous Rolling Mill

Continuous Rolling Mill

The main working principle of continuous rolling mill is that when the billet is heated and discharged from the furnace, the oxidized iron sheet is removed by high-pressure water, and then the billet is processed in a four-roll reversible roughing mill. Finally, the intermediate billet which we need and suitable for continuous rolling mill is rolled. In the process of billet opening, the vertical roll can effectively ensure the precise width of the steel plate and the intermediate billet. After shearing, it will directly enter the continuous rolling mill to wait for processing and can be rolled to the specifications required by customers at one time. After rolling, the coiler will take up the coil. In the process of rolling, the roughing and finishing mill needs high-pressure water for secondary dephosphorization.

Introduction of Four-roll Continuous Rolling Mill:

Main Uses: This kind of mill is a one-way and irreversible four-high cold rolling mill. It is mainly used for rolling stainless steel, aluminum, carbon steel, copper and zinc, and other metals.

Main Features and Structures: The main components of this rolling mill are reducer, motor, universal joint shaft, human gearbox, stand, pressing part, electronic control cabinet, and roll system. The roll system uses special bearings for continuous rolling mill. The material of roll is 9Cr2Mo. If it is a large mill bearing base, it will also have a roll changing device.
