Cold rolling mill, the number of rolls is not the same, therefore, there are four-roll cold rolling mill, six-roll cold rolling mill and other unique types. As everyone knows, no matter what kind of cold rolling mill, in the cold rolling mill in such a large category, but the cold rolling mill has a full range of mastery, can not miss all kinds. Therefore, according to this practical provision, the following is the four-roll cold rolling mill to carry out scientific research and understanding, its content below.

Cold rolling mill, the number of rolls is not the same, therefore, there are four-roll cold rolling mill, six-roll cold rolling mill and other unique types. As everyone knows, no matter what kind of cold rolling mill, in the cold rolling mill in such a large category, but the cold rolling mill has a full range of mastery, can not miss all kinds. Therefore, according to this practical provision, the following is the four-roll cold rolling mill to carry out scientific research and understanding, its content below.


1. How to carry out cold and hot rolling on the four-roll cold rolling mill?

Four-roll cold rolling mill is a kind of cold rolling mill, the general practice of cold rolling work, but can use some countermeasures to carry out hot rolling work, two processing processes, saving production and manufacturing costs. Cold rolling is the same as general cold rolling. During hot rolling, only the work rolls on the cold rolling mill are drawn out, which exceeds the requirements of the work and actual operation.


2. Can the four-roller cold rolling mill adjust the cold rolling appearance according to different regulations?

If it is a general four-high cold rolling mill, then this is no way, but if some improvement is done, this can be maintained. The machine is composed of three parts: human body, reduction gearbox and electric motor. Its structure has been improved and upgraded. It is a new four-high cold rolling mill. Its active and driver rollers are cross-type generator sets that regulate cold rolling according to different regulations.


3. Which roll touches the piece in the four-roll cold rolling mill? Is the four-roll foil rolling mill a four-roll cold rolling mill?

The four-roller cold rolling mill has the characteristics of working roller, support point roller, transmission system roller, touch roller and so on. It is a drive roller, not a support point roller. In addition, this basis applies to hot rolling mills. Four-high rolling mill is generally not a reversible rolling mill, four-high cold rolling mill is reversible, so the two rolling mills are not the same, can not be equivalent.


4. Is the cold rolling force of the four-roller cold rolling mill clear based on work experience?

The cold rolling force of the four-high cold rolling mill is a key main parameter and cannot be ignored. The key to clear use value is based on specific conditions and cold rolling regulations. The operation experience of machinery and equipment has only clear practical value and cannot be used as accurate use value.
