Multifunctional single frame emulsion system of reversible cold rolling mill and emulsion operating method of multifunctional single frame emulsion system

Abstract

The invention relates to a multifunctional single frame emulsion system of a reversible cold rolling mill. The multifunctional single frame emulsion system comprises an emulsion tank, a temperature controller, a jetting device, a rolling mill, a collecting device, a magnetic filter device, a vacuum filter device, and the emulsion tank which are connected in sequence. Rolling oil and industry desalted water are introduced to the emulsion tank. The emulsion tank is characterized in that the rolling oil is diffused and the emulsion is heated in the emulsion tank. Another emulsion dirty box is arranged between the magnetic filter device and the vacuum filter device. The emulsion dirty box is communicated by another path at the same time and receives the overflow liquid from the emulsion tank. The vacuum filter device is connected to a connecting pipeline which is used for connecting the emulsion tank and the temperature controller at the same time. The rolling oil and the industry desalted water can be also introduced to the emulsion dirty box. The difference between the multifunctional single frame emulsion system provided by the invention and a conventional single frame emulsion system is that the invention provides two emulsion tanks capable of operating independently and jointly so as to meet the demands of rapid start, continuous production and production cleanness during production of the single frame rolling mill.

Description

technical field [0001] The invention relates to the field of metallurgy. Specifically, the invention relates to a metallurgical cold rolling mill lubrication system. More specifically, the invention relates to a multifunctional single-stand reversing cold rolling mill emulsion system and an emulsion operation method thereof. Background technique [0002] In the cold rolling process of modern steel strips, emulsions are generally used for cooling and lubricating production. The so-called cold rolling emulsions are rolling oils containing various surfactants that are crushed in water with a certain particle size under the action of agitators. of emulsion. In order to save the consumption of rolling oil, single-stand reversing rolling mills usually use such as figure 1 The emulsion circulation process shown. [0003] The overall process of the emulsion system is as follows: the emulsion tank is equipped with emulsion-the temperature control device accurately controls the temp...

AI Technical Summary

Problems solved by technology

Therefore, the rolling mill is often stopped before the steel type is switched, and the emulsion is reconfigured according to the needs, causing the rolling mill to be unable to run during this period, which significantly affects production efficiency
