The present invention provides a surface modifier for a rubber composition that can enhance appearance without decreasing ozone resistance of the rubber composition. The surface modifier for a rubber composition of the present invention includes a hydrocarbon-based anti-aging wax for rubber (B) and an appearance-improving agent (C), in which: the content of a linear monovalent primary alcohol is more than 1.5 parts by weight and less than 35 parts by weight per 100 parts by weight of the surface modifier for a rubber composition; per 100 parts by weight of the primary alcohol, the content of a component having 30 to 38 carbon atoms is more than 35 parts by weight; the content of a component having 12 to 26 carbon atoms is less than 25 parts by weight; and the content of a component having 42 to 68 carbon atoms is less than 25 parts by weight.

A cooling apparatus for hot rolling is installed on a downstream side of a finishing mill of a continuous hot rolling mill, and cools a steel sheet rolled by the finishing mill while being conveyed. The cooling apparatus includes first pinch rolls which, during an interval when the steel sheet fed out from a final stand of the finishing mill moves from a position of the final stand to a position where a surface temperature of the steel sheet reaches 850&#xb0; C. or less, pinch the steel sheet while applying tension of 3.9 MPa or greater.

The present invention provides a rolling mill of a plate or a sheet which eliminates rolling trouble due to warping of the rolled material and wavy shaped flatness defects running through the plate or sheet width direction such as 'waviness', 'full waves, and &#x201c;small waves' by providing a pair of a top and bottom work rolls, a pair of electric motors independently driving the pair of rolls, and control means for controlling one electric motor using the roll rotational speed as a control target value and controlling the other electric motor using the rolling torque applied to the rolled material from the work roll driven by that electric motor becoming substantially constant as a control target and using the drive torque as a control amount and a control technique of such a rolling mill of a plate or a sheet.
