Problems solved by technology

In addition, the production process of producing this kind of steel in foreign countries is complicated and confidential. It took Japan 15 years to develop it successfully, and South Korea tried many times to make it, but all failed. Compared with them, our production equipment is far inferior to them. Therefore, It is another technical key to study what kind of process route to use to produce products with higher precision using our existing equipment with low precision.

Embodiment Construction

[0014] When using this method to produce special-shaped flat steel for air conditioner blades, the following production process is adopted:

[0015] Treated billet → rolled into slab on 250×5 tandem mill and annealed → cold rolled and annealed on 200 mm two-roll cold rolling mill, then first time on 10 ton straight drawer Drawing and annealing → second drawing to finished size on a 10-ton straight bar drawing machine → removing surface contamination → plane and side straightening on a 9-roll cantilever straightening machine, and one by one according to the set length Cutting → check the appearance and dimensions of the finished product → anti-rust, packaging, and storage. Corresponding to the above process, do the following 6 control methods:

[0016] 1. Control of the size of the hot-rolled slab, the unit of size is mm:

[0017] (Thickness T+1~1.5) -0.30 +0.10 ×(width W+1~1.5) -0.40 +0.20 ×r 0.80~1.00

[0018] 2. The control of the drawing amount before the finished pr...

Abstract

A technology for manufacturing the shaped flat steel used for the blade of air conditioner includes such steps as pre-treating square billet, rolling to become flat billet, two-roller cold rolling, 10-ton drawing twice, cleaning surface, straightening, cutting short according to needed length, antirusting and packing.

Description

technical field [0001] The invention relates to a production method of special-shaped flat steel for air conditioner blades. Special-shaped flat steel for blades is widely used in the production of air-conditioning compressor blades. The section of the flat steel is asymmetrical on both sides, and the dimensional tolerance and surface quality are very high. The internal quality requirements are small heat treatment deformation, less retained austenite after heat treatment, good dimensional stability during the service process of the blade, wear resistance and corrosion resistance. Background technique [0002] With the continuous improvement of people's life, the demand for air conditioners that can improve the working environment and living environment is increasing. The key component of the air conditioner is the compressor, and the key part in the compressor is the blade, and its performance should be able to meet the requirements of the medium with strong chemical corr...
