Quality Requirements for Rolling Mills in Industrial Efficient Construction

The distribution of elastic flattening along the length of the roll is asymmetric. If the elongation rate is large at the edges, the appearance hardness of the support roll of the rolling mill is generally around HS45. However, observations by experts might reveal contrasting situations. Thin steel plates are usually marketed as single sheets cut from coils and sheared into definite lengths and widths. The difference depends on the deflection values of the roll due to pressure. To improve the accuracy of the thickness control system, the poor plate shape has a significant impact on the rolling operation. If the elastic deformation characteristics of the working roll are not considered, it can also affect the yield, leading to errors in the results. Studying the factors that affect the actual shape of the roll gap significantly increases the deflection of the working roll itself.

The dimensions of the transmission flat head of the working roll must have a certain "medium thickness." The bearing seat is loaded onto a trolley or crane and placed in a closed or open washing tank. All the rolls on the rolling mill frame undergo preheating. In the finishing stage, changes in rolling speed affect factors such as tension, temperature, and friction coefficient, mainly because there is elastic flattening deformation between the working roll and the support roll. Detection software must make decisions in a very limited time. The two ends of the hollow roll have middle plugs. There are middle holes, grooves for fixing lifting, screw holes, and grooved shaft extensions for discarding the idler rolls before the rolling mill test run. The support roll neck has two shapes: cylindrical and conical. Especially when rolling thinner strip steel, the conditions are different.

In cold-rolled strip steel rolling mills, with the rapid development of the manufacturing industry, when designing the roll type, although there are still technical requirements to reduce the thickness difference of this section. The localization issue of high-speed wire rod rolling mills, whether from the processing capacity, processing equipment, processing experience, or quality management of the manufacturing plant, should be said to have the conditions for domestic manufacturing. In the current situation where the economic conditions and investment environment of enterprises nationwide are relatively tight, the transformation of rolling mills and the introduction of new high-speed wire rod mills from abroad, which consume a considerable amount of foreign exchange, are not realistic. Therefore, the localization issue must be given attention and support by leaders at all levels, and the development of our country's own high-speed wire rod rolling mill technology should be promoted to achieve the localization of high-speed wire rod rolling mill equipment as soon as possible.

(1) The hydraulic lubrication equipment is equipped in the production line of high-speed wire rod rolling mill. The quality of hydraulic lubrication equipment components is poor, especially the oil leakage phenomenon is very serious, and most of them are imported from abroad. Through the joint efforts and research of various equipment manufacturing plants and hydraulic component factories in China, now, except for a small number of instruments, fine filters, and high-power heaters, all components are developed by our country. Especially the development and use of oil seals have further improved the localization of hydraulic lubrication equipment and systems.

(2) The development and application of couplings in the production line of high-speed wire rod rolling mills. Now China can fully manufacture various types of couplings for complete sets of high-speed wire rod mills and Danieli small rolling mills, all of which meet international standards and have been put into use in various domestic high-speed wire rod mills, fully meeting the requirements.

(3) The development of guide and guard devices in the production line of high-speed wire rod rolling mills. In the past, the twisted guide and the high-speed rolling guide were imported components. The use of imported components for the production of rolling mills has obvious effects and also saves a considerable amount of foreign exchange.
