Embodiment Construction

[0017] In order to easily understand the technical means, creative features, goals and effects of the present invention, the present invention will be further described below in conjunction with specific illustrations.

[0018] Such as figure 1 As shown, a mechanical polishing process for the inner wall of a stainless steel storage tank includes the following steps:

[0019] 1) Coarse throwing: Use 60#~100# emery wheels to grind, polish or grind the surface of the workpiece to remove surface burrs, scratches, rust marks, scale, weld reinforcement, welding tumors, Welding slag, etc., just remove the surface oxide layer and expose the metallic luster;

[0020] 2) Fine polishing: Use 80# emery wheel and thousand impellers to further process the surface after rough polishing, remove the scratches left by rough polishing, and produce a smooth to medium bright surface;

[0021] 3) Fine polishing: Use 240#~320# fiber wheel and cloth wheel coated with polishing paste to polish the s...

Abstract

The invention discloses a mechanical polishing process of the inner wall of a stainless steel storage tank. The mechanical polishing process comprises the following steps: (1) rough polishing: adopting a 60#-100# carborundum grinding wheel to grind, polish or mill the surface of a workpiece so as to remove burrs, scratches, rust marks, oxide skin, excess weld metal of a weld bead, weld beading, welding slags and an oxide layer on the surface of the workpiece; (2) fine polishing: adopting a 80# carborundum grinding wheel and a flap wheel to further machine the rough-polished surface so as to remove the scratches left by the rough polishing and generate a smooth and medium shining surface; (3) elaborate polishing: adopting a 240#-320# fiber wheel and a rag wheel coated with polishing paste to polish the surface of the stainless steel storage tank so as to further reduce the surface roughness of stainless steel and realize the purpose of microcosmic smoothness; (4) polishing detection: adopting the center line average value method for detection, transversely moving a roughness detector on the surface of the stainless steel storage tank during detection, and recording the amplitude of variation of peaks and valleys. According to the invention, the mechanical polishing process is simple and reasonable, the production efficiency is high, and the product quality and property are stable.

Description

technical field [0001] The invention relates to the technical field of mechanical polishing, in particular to a mechanical polishing process for the inner wall of a stainless steel storage tank. Background technique [0002] With the development of the chemical industry, stainless steel vertical storage tanks are widely used as storage containers for chemical raw materials and products. Due to the particularity of many chemical raw materials and products, relatively high requirements are put forward for the roughness of the inner wall of the stainless steel storage tank, so the inner wall of the storage tank must be polished. As a surface treatment technology, polishing has been widely used in the inner wall treatment of large containers and pipelines in chemical, pharmaceutical, food and other fields. [0003] Mechanical polishing is to use a polishing wheel to rotate at a high speed on the stainless steel surface, and apply a certain pressure, which will cause the sta...
