Problems solved by technology

[0002] With the development of my country's economy, people's living standards have also increased significantly. With the improvement of living standards, the society has relatively high requirements for metal processing, especially in the processing of forgings. 0Cr23Ni13 stainless steel is used in forging. , this steel has a lot of alloy elements, belongs to austenitic heat-resistant stainless steel, has high deformation resistance, narrow forging temperature range, and poor forging process. When the steel heating temperature exceeds this temperature, the original free ferrite content in the steel will be reduced. It will increase significantly, which will seriously affect the quality of forging. Due to the narrow forging temperature range, the number of heating times during forging will be increased, which will seriously reduce the efficiency of forging production and increase production costs.

Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below.

[0022] A kind of forging process of 0Cr23Ni13 heat-resistant stainless steel, its forging process is:

[0023] Step 1. Forging material selection: 0Cr23Ni13 stainless steel is selected for forging according to process requirements during forging.

[0024] Step 2. Preheating before forging: Now place the forging that needs to be forged in a low-temperature furnace for slow fire preheating. When it reaches 600 ° C, keep the forging for 2 hours. By preheating the forging in advance, the forging steel can be reduced. The stress difference between the inside and outside of the body is used to prevent surface cracks from occurring during forging in a high-temperature furnace, which will affect the quality of the forging.

[0025] Step 3. Forging heating: place the preheated forging in a high-tempe...

Abstract

The invention provides a forging process for 0Cr23Ni13 heat-resistance stainless steel. The forging process comprises the first step of forging selecting, the second step of preheating before forging, the third step of forging heating, the fourth step of forging upsetting forging, the fifth step of circulating forging and the sixth step of water cooling treatment after forging. By adjusting and improving the machining for a forging and widening the forging temperature range, the number of melting-down heating in the forging process is reduced, and the forging efficiency is improved; and by conducting light upsetting forging multiple times, the precision of upsetting is improved, the quality of upsetting is improved, and the production cost is lowered.
