A Carburizing and Quenching Process for Ring Parts

Abstract

The invention relates to the field of heat treatment, in particular to an annular component carburizing and quenching technology. The technology comprises the following steps that annular components are thrown into a cleaning pond to be immersed and cleaned, a water-based cleaning agent is added in the cleaning pond, then, clean water is used for flushing the annular components thoroughly, accordingly, surface impurities and oil dirt of the annular components are removed, and the cleaned annular components are classified after being blown dry; the annular components with the high carburizing requirement are placed in material rods in an annular component carburizing furnace; the annular components with the low carburizing requirement are placed on material containing rods, the space in theannular component carburizing furnace can be sufficiently utilized, the carburizing efficiency is improved, the annular component carburizing furnace is subjected to temperature rise, and gas seepageagent methyl alcohol inflation starts after the temperature is increased to the proper temperature. Through changing of the carbon potential and the temperature in a furnace body, the annular component surface carburizing depth and surface hardness are guaranteed, annular component carburizing and quenching are continuously conducted, accordingly, the technology process is shortened, the transferring and heat treatment cost is reduced, and the production efficiency is improved.

Description

technical field

[0001] The invention relates to the field of heat treatment, in particular to a carburizing and quenching process for ring parts. Background technique

[0002] Carburizing and quenching is a common heat treatment process for metal materials. It can make the surface of the carburized workpiece obtain high hardness and improve its wear resistance. Traditional processes mainly include: low temperature tempering, pre-cooling direct quenching, primary heating quenching, carburizing high temperature tempering, secondary quenching cold treatment, induction heating after carburizing and other processes.

[0003] There are also carburizing furnace technical solutions in the prior art. For example, a Chinese patent with application number 201520330610 discloses a carburizing furnace, which includes a main furnace body and a sealing cover arranged on the upper end of the main furnace body. , the driving device arranged at the upper end of the seal, the inner cylinder p...
