Problems solved by technology

However, there is a phenomenon that the oil dripping method cannot be dripped, and the oil immersion method has the phenomenon that it is impermeable. No matter which method can make the oil film adhered to the surface of the stainless steel strip uniform, so that the surface of the stainless steel strip has less oil film and no oil. Rust resistance is poor
At the same time, since these two methods can only adhere the oil to the surface of the stainless steel strip, and cannot penetrate into the surface of the stainless steel strip, the stainless steel strip treated wit

Abstract

The invention relates to an oilless and antirust production method of a stainless steel band subjected to stress relief annealing. The production method comprises the steps: firstly, upwards rolling a steel band, applying a tension, spraying and re-rolling while the steel band is applied with the tension, downwards rolling, and cleaning so that the antirust processing of the stainless steel band is completed. The stainless steel band which is treated by adopting the production method and subjected to the stress relief annealing is better in antirust capacity of the whole surface, has an antirust function after being cleaned, and is capable of reducing the use cost of a customer; the probability of rusting a product produced by adopting the stainless steel band is lower.

Description

technical field [0001] The invention relates to a production method of a steel strip, in particular to a production method of an oil-free and rust-proof stainless steel strip after stress relief annealing. Background technique [0002] It is known in the production industry of the stainless steel strip that in order to ensure the stable performance of the stainless steel strip and eliminate the internal stress of rolling, it is usually necessary to carry out stress relief annealing to the stainless steel strip during the production process. Stress relief annealing will destroy the passivation film on the surface of the stainless steel strip, thus making the stainless steel strip lose its antirust function. In order to regain the anti-rust function of the stainless steel strip after stress relief annealing, anti-rust treatment is required. [0003] At present, the methods used in the industry for antirust treatment of stainless steel strips after stress relief annealing are ...
