Stainless steel rod rust removal device based on ice-solid scraping technology and application method

Abstract

The invention discloses a stainless steel rod rust removal device based on an ice-solid scraping technology and an application method, and belongs to the technical field of rust removal equipment. According to the scheme, due to the fact that water in outer wrapping conical bags is guided outwards through main water guide strips and auxiliary water guide strips, when the water makes contact with the surface of a stainless steel rod, a water film on the outer side of a rusting layer of the stainless steel rod can be urged to gradually form an ice layer by means of the characteristic that nitreis dissolved in water to absorb heat; the outer wrapping conical bags are urged to be extruded with each other by means of the low-temperature form shrinkage change of an outer spiral rust removal ring, and therefore built-in main magnet balls can be extruded outwards as the outflow of the water in the outer wrapping conical bags can be accelerated; and embedded spikes can be urged to drive end embedded balls to be embedded into the water film by means of the repulsive effect of the built-in main magnet balls on the embedded spikes, and therefore release of the water in the outer wrapping conical bags can be accelerated by means of the torsion of the auxiliary water guide strips, and the firmness of connection between scraping conical spikes and the outer spiral rust removal ring can be urged to be improved.

Description

technical field [0001] The invention relates to the technical field of derusting equipment, and more specifically, relates to a stainless steel rod derusting device based on ice-fixed scraping technology and a method for using it. Background technique [0002] Stainless steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, and the steel grades that are resistant to weak corrosive media such as air, steam, and water, or have stainless properties are called stainless steel; Corroded steel is called acid-resistant steel, and stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel according to its organizational state. Wait. In addition, it can be divided into: chromium stainless steel, chromium-nickel stainless steel and chromium manganese nitrogen stainless steel. There is also special stainless steel for pressure vessels "GB245...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when derusting stainless steel rods, acid etching or manual grinding is usually used. However, in the actual processing process, manual grinding is more troublesome, which reduces the work efficiency of technicians, and acid etching is also difficult. Human observation is required at all times, so as to reduce the possibility of excessive acid etching of stainless steel rods and make its surface uneven
