Problems solved by technology
[0003] In the hot rolling process, due to the high temperature of the roll during rolling, the friction coefficient between the high-speed steel roll and the rolled material is also large, and the rolling load will be greatly increased, resulting in slippage after thermal adhesion between the roll and the rolled material phenomenon, and slipping will greatly reduce the speed of the rolling plate. In the current production process, oil lubrication is usually used to properly reduce the friction coefficient and roll temperature, so that the rolling mill can run smoothly. However, due to the uncontrollable amount of oil lubrication, excessive After lubrication, the thickness of the oil film increases, and slippage also occurs

The invention discloses a roller lubricating oil adjusting device and a using method thereof. The roller lubricating oil adjusting device comprises a lower roller, an upper roller and a base; a gap isformed between the lower roller and the upper roller; the lower roller is rotationally arranged on the base; an oil injection pump is arranged on the feeding side of the lower roller; a nozzle is arranged on the oil injection pump; and the oil injection pump is connected with an oil tank and an adjusting device through pipelines. The device can adjust the oil injection amount when the rollers slip, the constancy of the thicknesses of oil films between the rollers and a rolled material is ensured, a rolling mill always keeps normal work, and the device can greatly improve the production efficiency.
Description
technical field [0001] The invention relates to the technical field of rolling mill equipment, in particular to a rolling lubricating oil regulating device and a using method thereof. Background technique [0002] The rolling mill is an industrial machine that presses the rolled material into shape. It uses the gap between the rolls to roll the rolled material into plates of different thicknesses. Among them, there are many types of roll materials according to the material of the rolled material, and the high-speed steel roll It is the most widely used hot rolling roll among them. [0003] In the hot rolling process, due to the high temperature of the roll during rolling, the friction coefficient between the high-speed steel roll and the rolled material is also large, and the rolling load will be greatly increased, resulting in slippage after thermal adhesion between the roll and the rolled material phenomenon, and slipping will greatly reduce the speed of the rolling plate...
