Embodiment Construction

[0020] The present invention will be further described below in conjunction with the embodiments, and the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other used embodiments obtained by persons of ordinary skill in the art without creative efforts all belong to the protection scope of the present invention.

[0021] The processing method of the cold-rolled plate of a kind of freezing equipment of the present invention comprises the following steps:

[0022] Step 1, raw material processing, removing dirt on the stainless steel plate;

[0023] Step 2. At the beginning of rolling, the temperature of the inlet stainless steel plate is kept at 46-50°C. During the cold rolling process, the emulsion is sprayed on the stainless steel plate. The flow rate of the emulsion in the rolling direction is 3000-3200L / min, and the flow rate of the emulsion in the rolling direction is 1500L / ...

Abstract

The invention belongs to the technical field of refrigerating equipment, and discloses a processing method of a cold-rolled sheet of a refrigerating device. The processing method of the cold-rolled sheet of the refrigerating device solves the problem of rough surface and low corrosion resistance of an existing stainless steel cold-rolled sheet. The method comprises the following steps: 1, treatingraw materials, namely, removing pollutants on a stainless steel sheet; 2, keeping the temperature of the stainless steel sheet of an inlet to be 46-50 DEG C during starting rolling; and injecting emulsion to the stainless steel sheet during cold rolling, wherein the flow rate of the emulsion in the rolling direction is 3000-3200L / min, and the flow rate of the emulsion in an outlet in the rollingdirection is 1500-1600L / min; 3, annealing and pickling; 4, grinding and modeling; and 5, passivating under the temperature of 50-55 DEG C through a passivating solution; washing the surface with deionized water; and drying.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a method for processing cold-rolled plates of refrigeration equipment. Background technique [0002] Different refrigeration methods of cold storage equipment use different equipment. At present, vapor compression refrigeration is the most widely used. The main equipment includes compressors (see fluid conveying machinery), condensers, evaporators and throttle valves. Compressors are used to compress and transport refrigerant vapor, among which piston type and centrifugal type are the most widely used. When items are cooled or frozen, a certain amount of heat will be released, and the enclosure structure of the refrigeration device will also transfer a certain amount of heat when it is in use. Therefore, in order to maintain the low temperature conditions in the refrigeration unit, it must be installed. [0003] Most of the refrigeration equipment is...
