Problems solved by technology

Once the spare configuration of the rolls is insufficient, it will be difficult to schedule and turn over the rolls, and even stop the machine to wait for the rolls
Sometimes the hot rolls are directly ground on the grinding machine without waiting for cooling, resulting in a decrease in the shape quality of the rolled products and an increase in the scrap rate

Embodiment 1

[0028] An oil-bath cooling device for a hot roll to be ground is composed of an oil bath 1, a circulation pump 2, and a guiding inlet and outlet oil pipe 3. The oil bath is rectangular, and the bottom is provided with at least one pair of roller pillows, and the roller pillows are used to place the hot roll to be ground; two holes are opened on the wall of the oil bath to form an oil outlet and an oil inlet, and the openings It is connected with the circulation pump 2 through the guiding oil inlet and outlet pipe 3 . The oil outlet and the oil inlet are located on the same side of the oil bath tank body wall, and a valve 4 is installed outside the oil bath tank to facilitate venting and maintenance.

Embodiment 2

[0030] An oil-bath cooling device for a hot roll to be ground is composed of an oil bath 1, a circulation pump 2, and a guiding inlet and outlet oil pipe 3. The oil bath is rectangular, and the bottom is provided with at least one pair of roller pillows, and the roller pillows are used to place the hot roll to be ground; two holes are opened on the wall of the oil bath to form an oil outlet and an oil inlet, and the openings It is connected with the circulation pump 2 through the guiding oil inlet and outlet pipe 3 . The oil outlet and the oil inlet are set on the adjacent tank wall of the oil bath, and a valve 4 is installed outside the oil bath to facilitate venting and maintenance.

Embodiment 3

[0032] An oil-bath cooling device for a hot roll to be ground is composed of an oil bath 1, a circulation pump 2, and a guiding inlet and outlet oil pipe 3.

Abstract

The invention belongs to the technical field of metallurgical industry equipment, and relates to an oil bath cooling device for hot rolls to be ground and a use method thereof. The cooling device is composed of an oil bath, a circuiting pump and guide oil inlet and outlet pipes. The oil bath is rectangular, and at least one pair of roll bearers are arranged at the bottom of the oil bath and used for placing the hot rolls to be ground; two holes are formed in the body wall of the oil bath and form an oil outlet and an oil inlet, and the holes are connected with the circulating pump through the guide oil inlet and outlet pipes. Oil bath cooling is applied to the hot rolls to be ground for the first time, the hot rolls are naturally cooled to a normal temperature in a shorter time, the roll grinding period is shortened, and the utilization rate of the rolls is increased. By means of the device, the number of the arranged rolls can be effectively decreased, so that the production cost of an enterprise is lowered, and the possible problems that because rolls are insufficient or rolls are ground when hot, the roll shape is poor, rolling is unstable and the strip shape of rolled products is poor can be avoided.

Description

Technical field [0001] The present invention is a technical field of metallurgical industrial equipment, involving the cooling roller cooling device to be ground, especially a cooling device and its usage method for hot rolling roller oil baths. Background technique [0002] In the field of metallurgical industry, rolling rolling rolling and processing various metal plates are widely used through rolling rolls. At present, four rollers and six -roller rolling machines are generally used. The working roller is a device that is directly contacted with rolling parts.The working roller carries higher intensity pressure to maintain auxiliary roller added to the working roller's work area.Their rolling type and surface quality are important factors that affect the quality of the rolling parts. It is very important for ensuring stable rolling and plate flatness, which will especially affect the diarrhea and surface quality of the rolling parts.The grinding roller type and surface qualit...
