Six-roll cold rolling mill, which is a common type of cold rolling mill, and it has been widely used in some levels or industries, plus, it is one of the commodities in the online platform. Therefore, it is urgent to master this kind of cold rolling mill, and can not be carried out carelessly. So below, why not in the existing basic, to develop down again, and then, let everyone deep in them, and have a full understanding.
1. In the six-high cold rolling mill, the roll channeling is to ensure what?
The roll channeled in the six-high cold rolling mill is to ensure the plate shape of the inlet and outlet of hot rolled strip steel, and it is generally rolled up in the middle. Its standard deviation measurement is related to the diameter of the support plate roller, the center roller and the work roller. In addition, it is also related to the adjustment index of the center roller.
2. It will lead to the damage of the roll box of the cold rolling mill
People in the actual operation in the whole process of cold rolling mill, often appear the status of the roller box is damaged, the emergence of such a thing will be more serious harm to all the normal operation of all extrusion machine, and many customers in the first encounter such a thing at that time, I can't find a way to deal with the first time, today's network built to give guys explanation.
Cold rolling mill technology professional manufacturer always has established express said, cold rolling mill roller box base case of damage of many are common elements, such as roll a wandering but actual operation staff didn't immediately find and handle, it can cause of work roll temperature rising, but without the oil under the condition of maintenance, serious friction is bound to cause the appearance of fire, Finally, the roll box of cold rolling mill is damaged. However, the roller ring in the cold rolling mill will be seriously blocked due to water flushing, and the high temperature will cause the working pressure of the work roll transmitted to the oil slick to increase, so this situation is caused by the damage of the roll box of the cold rolling mill.
And if cold rolling mill of refined oil products due to suffer more serious environmental pollution, there is more waste or oil temperature are not subject to the control of the situation, as there will be a roller box is damaged, therefore described in detail by several points of damage caused conditions, load or the roll gap is appear overload operation of cold rolling mill is caused by the presence of the poor, Therefore, the most reasonable way to deal with this situation is to remove and replace the roll box of the cold rolling machine immediately, but the operation of low speed must be carried out in the early stage, when all the temperature remains stable, it can be carried out more informed operation.
3. In the quality inspection of the six-high cold rolling mill, which aspect is the key to check?
To carry out the quality inspection of the six-high cold rolling mill, the key is to carry out all-round inspection of the three aspects of the cold rolling mill's appearance, specifications and characteristics. Among them, the appearance of the six-high cold rolling machine, the key is the shape and surface defects of the two, and in terms of specifications, the key is its length, total width and thickness of the three.
4. Six-high cold rolling mill, if there is a problem in the gap between the belt bearing and the wear-resistant lining plate, or the rolling bearing has a product quality problem, then what adverse effects will be caused? And, this kind of cold rolling mill, why the work roll choose middle roll drive system?
In the six-high cold rolling mill, if there is a problem in the gap between the belt bearing and the wear-resistant lining plate, or if there is a problem in the quality of the rolling bearing, then the cold rolling machine can not work normally, and the cold rolling quality and the actual effect is worse. For, the work roller selection of the middle roller drive system, because it can choose smaller diameter, and then, to reduce the amount of pressure, improve the production and processing efficiency.
