Description

Technical Field

[0001] This utility model relates to the field of anti-oxidation treatment technology, specifically an anti-oxidation treatment device for hot-extruded high-molybdenum alloys. Background Technology

[0002] In the production process of hot-extruded high-molybdenum alloys, anti-oxidation treatment is a critical step to ensure that the material is not oxidized at high temperatures. However, existing anti-oxidation treatment equipment has the following main problems:

[0003] 1. During hot extrusion, the metal surface is easily exposed to oxygen in the air, forming an oxide layer that affects the material's performance and quality. It is also impossible to uniformly control the oxidation of the entire metal surface, leading to severe localized oxidation.

[0004] 2. Traditional heating methods (such as resistance heating) often result in uneven heating, causing large temperature differences in different areas of the metal material, which affects the uniformity and performance of the material.

[0005] 3. Existing devices typically use a fixed pipe diameter design, which cannot be adjusted according to actual needs, thus limiting the flexibility and applicability of the device;

[0006] 4. When the existing equipment sprays anti-oxidation gas (such as argon), the gas distribution is uneven, resulting in poor anti-oxidation effect in some areas. Utility Model Content
