Abstract

PURPOSE:To achieve sufficiently an effect of lubrication by supplying a lubricant to a rolling material, taken out to the inlet or outlet side while running between rolling passes. CONSTITUTION:In a multipass mill for performing a single stand 3-passes rolling for instance, a rolling material 5 wrapped around inside work rolls 1, 2 is taken out to the outsides respectively by deflector rolls 8, 9. The taken out material 5 is lubricated by supplying a lubricant from lubricant supplying devices 10 at the inlet sides of the 2nd and 3rd passes respectively. In this way, the lubricating effect is exhibited even at the 2nd and 3rd passes where the severe lubrications are required, and an excellent product is obtained.

ここでは１スタンド３バス圧延について説明する。 Here, one-stand three-bus rolling will be explained.

と言う利点がある。As shown in Fig. 1, there is a conventional multi-pass rolling mill which is formed by a pair of inner work rolls 1゜2 and a pair of outer work rolls 3 and 4 placed outside so as to sandwich the inner work rolls. Are known. Note that 6 and 7 are backup rolls. According to some multi-bus rolling mills, one rolling stand can produce 3
Since it is possible to perform rolling for the number of rolling stands, there is an advantage that the entire rolling equipment can be downsized and equipment costs can be reduced.

ないという問題があった。However, in such conventional multi-bus rolling mills,
Since the rolling material was wound around the inner work roll 1.2, there was a problem that sufficient yI slipping could not be performed during steady rolling. Therefore, when the work roll 2.4 is loaded, a lubricant such as crude oil or Bonde (phosphorus 21 coating) is applied to the rolled material 5, but the 'AfIM agent is applied to the original plate of the rolled material 5. Even if it is attached, it becomes thinner in the 2nd and 3rd passes, where lubrication is more severe, resulting in a problem in that the lubrication effect decreases and stable rolling cannot be performed.
