Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling of steel plates, in particular to a steel plate rough rolling mill. Background Art

[0002] Hot rolling mill is a mechanical device used to further perform cold plastic deformation on hot rolled metal sheets. Its main goal is to achieve the required dimensional accuracy, surface quality and mechanical properties of metal sheets by rolling them at room temperature. The hot rolling process is carried out without heating, which can maintain the original grain structure of the metal and improve the strength, hardness and surface smoothness of the metal.

[0003] The existing hot rolling mill lacks a certain limiting mechanism during the rough rolling process of steel plates, which makes the steel plate body easily shift due to the squeezing pressure of the rollers when the steel plate enters the hot rolling assembly for rough rolling, thereby reducing the hot rolling effect of the steel plate that subsequently enters the hot rolling assembly. At the same time, the existing steel plates often need to be coated with hot rolling oil in advance before hot rolling, so that the steel plate body is more lubricated, which increases the possibility of steel plate shifting.

[0024] Through the above structure, the support legs 24 and the support base 5 support the feed seat 2, and the rollers 1 5 and 2 6 in the rolling groove 4 can perform rough rolling on the steel plate fed by the feed groove 10 on the limit seat 3, wherein the specific structure of each component is as follows:

[0025] Combined with Figure 3 and Figure 4 As shown, the transmission assembly includes a transmission gear 13 and a transmission gear 2 14. A transmission groove 15 is provided in the transmission seat 9. The roller 1 5 passes through the transmission seat 9 and one end of the roller 1 5 located in the transmission groove 15 is sleeved with the transmission gear 1 13.
