Embodiment Construction

[0039] The preferred embodiments of the rolling mill emulsified liquid external circulation heating method and heating device of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] see figure 1 , according to the rolling mill emulsified liquid external circulation heating method of the present invention, take the following steps:

[0041] A. The emulsified liquid flows out from the heat circulation tank and enters the heat exchanger through the circulation pump.

[0042] B. The thermometer collects the actual temperature data of the emulsified liquid in the thermal cycle box and sends it to the control processing unit.

[0043] C. The control processing unit compares the actual temperature data with the value of the preset temperature range, and judges whether the actual temperature data is less than the lower limit value of the preset temperature range, if so, sends an opening command to the steam control valve, and p...

Abstract

The invention relates to a rolling mill emulsifying liquid outer cyclic heating method, including the following steps: emulsifying liquid flows from a heat circulation box and flows into a heat exchanger through a circulation pump; the actual temperature data of the emulsifying liquid in the heat circulation box is acquired by a thermometer and is sent to a control processing unit; and the control processing unit sends order out. The heating device of the invention comprises a heat circulation box, a circulation pump, a heat exchanger, a thermometer, a steam control valve, a steam trap and a control processing unit. The invention has the advantages that heating effect is good, the temperature of the emulsifying liquid in the heat circulation box is even; the temperature controllability is strong, precise is high; systemic operation is stable, operation is simple; production cost is reduced; overhaul and maintenance of the device is convenient; the steam of systemic operation is not easy to enter the emulsifying liquid so as to ensure the quality of the emulsifying liquid not to be affected.

Description

technical field [0001] The invention relates to the field of cooling and lubricating systems for metallurgical equipment, in particular to a heating method and a heating device for external circulation of emulsified liquid in a rolling mill. Background technique [0002] At present, the emulsion is generally used as the cooling and lubricant of the continuous rolling mill to cool the deformation heat generated during the rolling process of the rolling mill, and to lubricate the rolled piece and the roll, so that it can be rolled smoothly and get a better plate surface. quality. The temperature of the emulsion must be strictly controlled within the specified range. Too low temperature is not conducive to the function of additives and other components in the rolling oil and affects lubrication; if the temperature is too high, the particle size of the emulsion is easy to increase, affecting the stability of the emulsion The formation of oil-water separation will affect the qua...
