Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate and strip finishing, in particular to an automatic water adding device for an emulsion oil tank of a hot rolling unit with high stability. Background Art

[0002] In the existing equipment for finishing aluminum plates and strips, the hot finishing continuous rolling unit cools and washes the strips by spraying emulsion onto the surface of the strips and rollers, and lubricates the rollers at the same time to ensure the surface quality of the rolled products and reduce roller wear. The quality of the emulsion directly determines the surface quality of the finished strips and is an important part of the hot rolling process control. Therefore, how to ensure the quality of the emulsion has become a difficult problem that needs to be solved urgently in improving the finishing process of aluminum plates and strips in hot finishing rolling mills. However, a long-term water addition method can stabilize the emulsion concentration in the emulsion main oil tank. Therefore, it is very important to design a high-stability automatic water adding device for the emulsion oil tank of the hot rolling unit.

[0003] However, most of the existing technical solutions have the following defects: in the continuous production process of hot finishing rolling, the amount of emulsion used is very large. In order to ensure the emulsion consumption of the rolling mill, a large amount of water is often added at one time, which makes it impossible to control the concentration of the emulsion within a stable range, and ultimately causes large fluctuations in the emulsion concentration in the emulsion tank, affecting the emulsion indicators. At the same time, in order to stabilize the emulsion concentration in the emulsion main tank, a slow and long-term water adding method is usually adopted when adding water. However, the conventional water filling mode has a large proportion of human influence factors, which not only fails to stabilize the emulsion concentration, but also causes additional consumption of rolling oil. Therefore, the utility model provides a high-stability automatic water adding device for the emulsion tank of a hot rolling unit to solve the above-mentioned problems. Utility Model Content

In order to ensure the emulsion usage of the rolling mill, a large amount of water is often added at one time, which makes it impossible to control the concentration of the emulsion within a stable range, and finally causes large fluctuations in the emulsion concentration in the emulsion oil tank, affecting the emulsion index. At the same time, in order to stabilize the emulsion concentration in the emulsion main oil tank, a long-term water-adding method is usually adopted when adding water. However, the conventional water-adding mode has the problem of a large proportion of human influence factors, which not only fails to stabilize the emulsion concentration, but also causes the problem of additional consumption of rolling oil.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic water-adding device for an emulsion oil tank of a high-stability hot rolling mill unit, comprising an emulsion main oil tank, a water flow control pipeline is arranged at the left end of the emulsion main oil tank, and a liquid sensor is installed inside the water flow control pipeline, characterized in that: it also comprises a first solenoid valve arranged at the middle end of the water flow control pipeline, and the first solenoid valve is externally connected to a controller body, a bite-in and threading module is arranged at the right end of the controller body, and a tail-swinging end module is arranged at the left end of the controller body;

[0010] Preferably, the tail-swing ending module can act on the controller body, and the controller body can control the water pump body and the first solenoid valve to close.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the high-stability hot rolling mill emulsion oil tank automatic water adding device replenishes the water volatilized in large quantities by the emulsion during rolling by using the electromagnetic valve signal control, thereby stabilizing the concentration of the emulsion. Compared with the traditional technology, it has the function of fully automatic water adding, reduces the labor maintenance cost, and avoids the misoperation caused by human factors. The specific operation is as follows;

[0012] 1. It is equipped with a biting and threading module and a water pump body. The power of the water pump body is transferred to the inside of the water flow control pipe for flow. The first solenoid valve is in an open state, so that the water flows through the liquid sensor into the inside of the emulsion main oil tank, completing the water adding operation, which is convenient for realizing the automatic water adding function of the emulsion oil tank of the hot rolling mill;

[0013] 2. A tail-swinging end module and a first solenoid valve are provided. When the first solenoid valve and the water pump body are closed, the water tank body stops supplying water through the inlet pipe, the source of water in the water flow control pipeline is blocked, and the emulsion main oil tank is stopped from adding water, which is convenient for realizing the control of the emulsion concentration by a long-term water addition method for the emulsion oil tank of the hot rolling unit, stabilizing the emulsion concentration of the emulsion main oil tank and improving product quality;
