Abstract

The invention discloses a rolling oil composition for a double frame reversible rolling mill. The rolling oil composition comprises, by weight, 70-95% of a polyol ester oiliness agent, 0-5% of a polyphosphate extreme pressure antiwear agent, 0.1-10% of a thioether extreme pressure antiwear agent, 0.1-5% of a metal deactivator, 0.1-3% of a free radical inhibitor, 0.1-15% of a fatty alcohol polyether surfactant, and 0.1-20% of a polysorbitol nonionic surfactant. The rolling oil composition, which specially aims at specific technological conditions of the double frame reversible rolling mill, such as characteristics of large reduction rate, much very thin plate production and the like, has good fluid lubrication, boundary lubrication and extreme pressure lubrication performances, has a wide mixed lubrication area window, and provides excellent lubrication performances during low speed rolling and high speed rolling, is suitable for rolling of high strength steels and large deflection requirements, and simultaneously has a good cleaning property.

Description

technical field [0001] The invention belongs to lubricants for metal processing technology, in particular to a rolling oil composition specially used for double-stand reversing rolling mills. Background technique [0002] In recent years, with the increasing demand for steel products, the steel market has increasingly required equipment, especially rolling mills, with higher output capacity and product quality. Most iron and steel producers usually use reversing rolling mills. The single-stand reversing rolling mill has a production capacity of 200-600kt, while the double-stand reversing rolling mill can reach 300-1000kt, and can produce a wide range of various steel products. [0003] But the double rack also has its obvious disadvantages: (1) The yield is low. The theoretical maximum yield of double racks is only about 95%. Because of the reversible rolling, part of the head and tail cannot be rolled, and the yield is not only lower than that of continuous rolling, but a...
