Description

Technical Field

[0001] The utility model relates to the technical field of emulsion heating, in particular to an emulsion heating device. Background Art

[0002] Rolling is a processing method that passes metal through the gap between two relatively rotating rollers on a rolling mill, and is rolled and deformed into profiles (such as steel plates, round steel, angle steel, channel steel, etc.). Under certain conditions, the rotating rollers exert pressure on the rolled piece, causing the rolled piece to undergo plastic deformation, and the oil used for this processing method is rolling oil. Rolling oil is usually used for process lubrication of large and medium-sized cold rolling units, mainly emphasizing lubricity, that is, water-free spreading, also known as oil-water separation. The oil and water are separated at the moment when the rollers contact the strip, and a layer of oil film is attached to the surface of the strip to play a lubricating effect, which is generally semi-stable. Since cold processing of steel produces work hardening, which increases the difficulty of processing, the use of rolling oil for process lubrication rolling oil can effectively reduce the roller consumption and mill power consumption, and can roll thinner products. At the same time, since the existing rolling methods are divided into hot rolling and cold rolling, rolling oil can be divided into hot rolling rolling oil and cold rolling rolling oil according to the processing technology.

[0003] The rolling oil used in cold rolling is an emulsion, and the temperature of the emulsion will have different effects on the operation of the rolling mill. If the temperature of the emulsion is too low, the viscosity of the emulsion will increase, reducing the lubrication effect, thereby increasing the friction between the rolled piece and the roller, increasing the energy consumption during the rolling process, and reducing the efficiency of the rolling mill. Low temperature will also cause the water in the emulsion to freeze, affecting the volume and fluidity of the emulsion, and further affecting the uniformity and stability of the rolling mill production. If the temperature of the emulsion is too high, the particle size of the emulsion will increase, affecting stability and increasing oil consumption. When rolling thin-gauge strip steel, excessively high temperatures may make the plate shape difficult to control and increase the rolling force. Therefore, the temperature of the emulsion used for cold rolling is generally controlled between 45°C and 55°C to ensure the rolling effect and the performance of the emulsion.

[0004] There are many methods for heating emulsions, including high-temperature heat transfer oil heating, steam heating, and commonly used steam heating and electric heating. However, when high-temperature heat transfer oil reaches a certain high temperature during use, if it is not cooled in time, the emulsion will be overheated. Therefore, this application proposes a technical solution to solve the above problem. Utility Model Content
