Abstract

The invention relates to a pre-oxidation technology for improving wind power gear gas carburizing efficiency. The pre-oxidation technology includes the following steps that carburizing steel is slicedinto a gear-shaped sample; the sample is subjected to thermal refining; the sample is subjected to ultrasonic cleaning and drying after grinding; the sample is placed in a program control box type electric stove and is subjected to the pre-oxidation treatment; and the sample is placed into a gas carburizing multipurpose stove, and is subjected to carburizing, quenching and tempering treatment. The pre-oxidation technology has the beneficial effects that the pre-oxidation treatment is carried out before the gas carburizing, an oxidation film layer is formed on the sample surface, wettability of the sample surface is increased and the pre-oxidation treatment is beneficial for absorbing activated carbon atoms; the oxidation film is preferentially restored during the process of gas carburizing, through the defect of existing a plurality of holes on the sample surface, permeating of the activated carbon atoms into the base body, and a quick channel is provided for diffusing the carbon atoms; and gas carburizing efficiency is greatly improved, carburizing time is greatly shortened in the condition of reaching the same layer depth of the carburizing and the energy is saved.

Description

technical field

[0001] The invention relates to a pre-oxidation process for improving gas carburizing efficiency of wind power gears. Background technique

[0002] Wind power gears are the key components of wind power generators. Because wind power generators are generally placed in wilderness, field, mountain pass, seaside and other places with high wind energy and no shelter around, the natural environment is harsh, transportation is inconvenient, and repair is very difficult. Wind power gears Once a failure occurs, it will seriously affect the economic benefits of the wind farm, so high requirements are placed on the reliability and working life of the gear.

[0003] At present, in the surface hardening technology of gears at home and abroad, carburizing treatment has always been the preferred process for strengthening wind power gears due to the maturity of the technology and the development of supporting technologies such as temperature control and carbon potential cont...
