Microwave heating device for heating cold-rolling pickling process medium

Abstract

The invention provides a microwave heating device for heating a cold-rolling pickling process medium. The device comprises a circulating tank, a circulating pump, a pipeline, the microwave heating device, a three-way valve and a pickling tank, wherein the microwave heating device comprises a microwave heater, a cavity, a heating tube, a temperature sensor, a heat tube inlet and a heating tube outlet. The microwave heating device is arranged between the circulating tank and the pickling tank to ensure that the process medium is heated when passing through the microwave heating device, and the process medium is delivered to the pickling tank to wash a titanium belt when the repeatedly heated process medium is heated to the temperature meeting the production requirement. The device can directly heat the process medium without a heat exchange process, improves the efficiency, realizes zero emission of carbon, and avoids the problems of environmental pollution and energy waste caused by using a boiler.

Description

technical field [0001] The invention relates to a microwave heating device for heating a solution, in particular to a microwave heating device for heating a cold rolling pickling process medium, and belongs to the field of steel and nonferrous metal smelting equipment. Background technique [0002] Pickling is an essential process in the production process of cold rolling of steel and non-ferrous metals. The main function of pickling is to remove the surface scale and pollutants after hot rolling to obtain a clean surface and avoid rolling produce defects. Taking cold-rolled titanium strip pickling as an example, the pickling process is divided into cleaning section, pickling section and rinsing section according to the process sequence, and the cold-rolled titanium strip is cleaned, pickled and rinsed respectively. The process medium in the cleaning section is desalted water, containing a certain concentration of HNO 3 Mixed acid solution with HF, the concentration of the...
