Abstract
The invention relates to a manufacture method for a hard state 304 finish stainless steel belt which includes the following steps: (1) adopting a stainless steel belt as a raw material; (2) rolling and processing; (3) annealing; (4) finish rolling; (5) finishing; (6) checking, packaging and warehousing. The method not only improves the mechanical property of the finally finished product, but also eliminates the internal stress of the stainless steel caused by primary rolling and improves the performance quality of the finally finished product; simultaneously, the manufacture method is simple and easy to operate with the low cost.
Description
Technical field
The invention belongs to the manufacturing method of stainless steel band field, particularly relate to a kind of 304 precise stainless steel strip production methods.
Background technology
The stainless steel band product in use will carry out deep processings such as punching press, clod wash, and the deep process difference is also different to the mechanical property requirements of stainless steel band product.Usually, the stainless steel band product of stretched punch process is hard attitude, and the mechanical property requirements of the hard attitude product of 304 materials is Hv=380 ~ 420.
In the prior art, stainless steel adds directly carry out finish rolling man-hour after first rolling processing, but can produce stress because first rolling back stainless steel is inner, influence the effect of finish rolling, dissimilar steel band Hv requires different prior aries to be difficult to satisfy requirement to the mechanical property of finished product simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of hard attitude 301 precise stainless steel strip production methods to solve the defective that is difficult to guarantee the finished product mechanical property in the prior art.
Technical scheme
The invention provides a kind of hard attitude 304 precise stainless steel strip production methods, may further comprise the steps:
(1) adopting stainless steel band is raw material;
(2) rolling processing;
(3) annealing in process;
(4) finish rolling;
(5) finishing is cleaned, and straightening cuts into the width specifications of customer requirements then;
(6) check, packing warehouse-in.
Annealing temperature is 1050 ℃～1060 ℃ in the described step 3, and 15 minutes～25 minutes, decomposed ammonia protection, cooling fast.
Cold rolling machining deformation rate 42%～45%, three passages in the described step 4 are rolling.
Beneficial effect
The present invention has carried out once annealing after first rolling, not only improved the mechanical property of end product, and has eliminated stainless steel because of the internal stress that breaking down produces, and has improved the performance quality of end product, and production method is simple simultaneously, and cost is low.
