The present invention relates to a cold rolling method using a solid lubricant as rolling oil. In cold rolling, rolling lubricating oil is essential for efficiently rolling products of good quality. Conventional lubricating oil supply means for cold rolling include:
A coolant header was provided on the entry/exit side near the work roll, from which a rolling oil emulsion was injected and supplied to the roll and strip surfaces. However, in the conventional emulsion injection method, the injected oil sometimes scatters and does not adhere effectively to the steel plate surface.
There are disadvantages in that the conditions are not necessarily satisfactory for high-speed rolling, and there are also disadvantages in that the ash and iron in the coolant cause contamination, resulting in poor surface quality and a decrease in yield. An object of the present invention is to provide a rolling method using a solid lubricant that can eliminate the various drawbacks of conventional cold rolling. A feature of the present invention is that it uses a thermosetting lubricant, which has conventionally been used only in pultrusion pipe manufacturing methods, to form a uniform coating of lubricant on the entire surface of the work roll. The main objective is to improve the lubricity, and the lubricant used is, for example, a thermosetting lubricant containing an acrylic resin as a main component, such as Bonderite or Bondaryube. As a lubricant application means, as shown in Fig. 1, lubricant 2 is applied to the entrance side of all stands in the rolling mill.
A container or tank 2 containing 1 is provided, for example, first attached to a dip roll 3 made of steel,
This is then transferred to coating roll 4 made of felt, etc., and then work roll 1 of the rolling mill.
Apply to. A solid lubricant is a substance whose liquid content evaporates and solidifies depending on the temperature, and the moment it is applied to a work roll, it solidifies and forms a film that adheres to the roll surface. As shown in FIG. 2, this coating 22 is formed uniformly over the entire length of the work roll 1, and the film thickness t is preferably in the range of 3 to 10 .mu.m, and most preferably about 5 .mu.m. Note that lubricants will solidify at the same time as they are applied even if no special considerations are taken, but in order to ensure solidification, it is necessary to control the temperature of the work roll and to It is desirable to implement heat curing settings depending on the concentration of the agent. When carrying out the method of the present invention, supply of rolling oil by the conventional method is completely unnecessary, and a sufficient lubrication effect can be obtained only by the method of the present invention. Table 1 shows a comparison of the rolling results obtained by the method of the present invention and the conventional method. The rolled material is 1200mm wide and 2.3mm to 0.4mm thick.
Rolling was performed up to 83%.
