Example Embodiment

[0039] The preferred embodiments of the rolling mill emulsion crude oil temperature control method and control device of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] The manufacturer transports the crude oil to the site by tank truck, and uses the unloading pump to suck the crude oil from the tank truck into the crude oil tank through the hose. The crude oil tank plays a role in storage and transit, and is generally stored for one month. The pH value of crude oil is 4.0-7.0, and the density is ρ=0.95kg / L. If the crude oil temperature is too low, it is generally easy to solidify below 30°C. If the crude oil temperature is too high, it will cause bacteria to grow and deteriorate. Therefore, it must Control the crude oil within a certain temperature range.

[0041] See figure 1 According to the temperature control method of the rolling mill emulsion crude oil of the present invention, the following steps are taken:

Abstract

The invention relates to a method for controlling temperature of crude oil for emulsion of a rolling mill and a control device. The method comprises the steps of: arranging a heating device on the outer part of a crude oil tank; adopting a circulation heating pump arranged at the tail of the crude oil tank to transfer crude oil to a heat exchanger for heat exchange; simultaneously adopting a temperature controller on the crude oil tank to control the on and off of the heating device; and transferring crude oil to the top of the crude oil tank for outer circulation heating so as to keep the temperature of crude oil inside the crude oil tank at a preset value. A control device comprises the heating device consisting of the circulation heating pump and the heat exchanger, the temperature controller, a steam control valve, a steam trap and pipelines connecting the components, wherein the circulation heating pump is arranged at the tail of the crude oil tank, the heat exchanger is arranged on the side of the crude oil tank and the temperature controller is arranged on the crude oil tank. The invention has the advantages of good heating effect, equal crude oil temperature, high temperature-control property and precision, simple and convenient operation process, non-steam entering the crude oil and non-impact on crude oil quality.

Description

technical field [0001] The invention relates to the field of cooling and lubricating systems for metallurgical equipment, in particular to a method and a control device for controlling the temperature of crude oil required for mixing emulsions in rolling mills. Background technique [0002] At present, the emulsion is generally used as the cooling and lubricant of the continuous rolling mill. The emulsion is made of crude oil and desalted water. The crude oil is specially prepared by emulsifying and adding trace components provided by professional oil suppliers. Crude oil has strict requirements on temperature. If the temperature is too low, it will solidify and be difficult to transport. If the temperature in crude oil is too high, bacteria will multiply and the crude oil will deteriorate. [0003] The previous temperature control method is to install steam coils in the crude oil tank, so there are the following problems: [0004] 1. Uneven heating; [0005] 2. It is easy...
