Benefits of technology

This patented technology allows for better quality control during production compared to previous methods like conventional heat-treatment techniques used beforehand. It achieves these benefits through an inductive heat treatment (IH) method where high temperatures can be applied at two ends without affecting any other part's properties such as surface roughness or shape accuracy. By controllably adjusting the position of the heat sources within specific ranges, it simplifies the manufacturing process while reducing costly material wastage.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving thermal processing techniques used on highly precise machinery tools such as those made from materials like chrome carbide (GCR). Current processes involve several steps involving different types of heat sources or equipment, which can lead to variations in product's properties due to temperature changes caused by these factors.

Abstract

The invention relates to the technical field of GCr15 heat treatment processes, in particular to a GCr15 heat treatment process. The GCr15 heat treatment process is used for steel parts made of GCr15.The GCr15 heat treatment process comprises the following steps that 100, a steel part is heated to the austenite temperature through induction heating equipment to be subjected to quenching heating treatment; 200, quenching cooling treatment is carried out on the steel part subjected to the quenching heating treatment through induction cooling equipment; 300, tempering heating treatment is carried out on the steel part subjected to the quenching cooling treatment through the induction heating equipment; and 400, natural cooling is carried out on the steel part subjected to the tempering heating treatment. A single induction heating process and a single temperature control cooling process are adopted for the steel part, and multi-section quenching heating and tempering heating treatment are adopted in the treatment process, so that a produced steel part is small in hardness scatter difference, tiny in deformation and small in turning amount, and energy consumption is low while the efficiency is guaranteed.
