AI Technical Summary
Traditional carbon steel mine fans have a short service life in environments with high dust, high temperature, high humidity and corrosiveness, and existing technical measures cannot fundamentally solve their lifespan problem.
The surface of a carbon steel fan is cleaned, polished, ceramicized, polished again, and ion-cured using a multi-component composite ceramic membrane to form a multi-component composite ceramic structure layer with a thickness of 15μm-30μm. This process includes preheating and ion curing treatments at temperatures between 350-600℃ for 120-300 minutes.
It significantly increases the service life of carbon steel fans by 2 to 5 times, reduces production costs, and enhances the grain boundary strengthening, corrosion resistance, and wear resistance of the material.
Abstract
Description
TECHNICAL FIELD
[0001] The application relates to a surface strengthening treatment method, in particular to a multi-element composite ceramic film surface strengthening treatment method for a mine fan. BACKGROUND
[0002] Generally, carbon steel is prone to rust in a humid, acid or alkaline or corrosive gas environment, which long-term influences the appearance and structural strength of equipment, and thus needs regular rust-proof treatment or coating protection, and the long-term maintenance cost is relatively high, and the service life is relatively short. The service life of a traditional carbon steel fan is about one year without protective measures in a harsh environment, and can reach 2-3 years after heat galvanizing and hard chromium plating treatment. The short service life of the fan seriously restricts the production efficiency of the mine, and makes the maintenance cost high.
[0003] In order to solve the problem, the prior art measures are as follows: 1. replacing the material, in a harsh environment, preferentially selecting a carbon steel fan with corrosion-resistant coating treatment, or a fan with a stainless steel material for key components. For an environment with particularly strong corrosion, a glass steel fan or a stainless steel fan is directly selected. 2. Strengthening protective measures, surface treatment: heat galvanizing, plastic spraying or brushing corrosion-resistant paint (such as epoxy resin paint) on the carbon steel fan. Isolated installation: in a corrosive gas environment, the fan is installed in a well-ventilated position, or an isolation cover is additionally installed. Filtering device: in an environment with more dust, a filtering device is additionally installed at the air inlet of the fan to reduce the entry of particulate matter. Although these measures can reduce the factors affecting the service life of the fan to a certain extent, they cannot fundamentally solve the problem of the short service life of the carbon steel fan. SUMMARY
[0004] The application solves the technical problem of providing a multi-element composite ceramic film surface strengthening treatment method capable of prolonging the service life of a carbon steel fan.
[0005] The technical solution adopted by the application to solve the technical problem is as follows: a multi-element composite ceramic film surface strengthening treatment method for a carbon steel fan, comprising the following process steps: A. performing surface cleaning and polishing treatment on the carbon steel fan, and the treatment time is 2-4 min; B. performing surface ceramization treatment on the carbon steel fan obtained in step A, so that a multi-element composite ceramic tissue layer with a thickness of 15-30 mu m is formed on the surface of the carbon steel fan, and the temperature condition of the surface ceramization treatment is 500-600 DEG C, and the treatment time is 120-300 min; C. performing polishing treatment on the carbon steel fan obtained in step B to remove the loose layer on the surface; D. The carbon steel fan obtained in step C is subjected to ion solidification treatment, the temperature condition of the ion solidification treatment is 350-500 DEG C, the treatment time is 10-30 min, the surface of the carbon steel fan is formed with a multi-element composite ceramic organization layer with a thickness of 20-35 mu m, the multi-element composite ceramic organization layer is composed of square and hexagonal crystal system ceramic phases.
[0006] Further, before the surface ceramization treatment of the carbon steel fan in step A, the carbon steel fan is subjected to a preheating treatment process, the preheating treatment process is quenching and tempering treatment.
[0007] The application has the advantages that the carbon steel fan surface layer material grain boundary is strengthened and stabilized, the carbon steel fan hole type surface corrosion resistance and wear resistance are improved, the carbon steel fan surface layer fatigue resistance is improved, the service life of the carbon steel fan can be significantly improved and the production cost is reduced, and the service life of the carbon steel fan can be increased by 2 to 5 times.
