Problems solved by technology

During the preparation process of quenching and tempering process, in order for the finished product to reach HRC43-47 (to ensure that the sole material has a certain strength and toughness), it is necessary to strictly control the quenching hardness and the uniformity of tempering temperature. However, this is very difficult in the actual production process. Difficult to control, there will be problems with sufficient toughness of the finished product (the number of fatigue times exceeds 500,000) but insufficient puncture resistance or sufficient puncture resistance but insufficient toughness, and the stability of product quality is poor
At the same time, the 40Mn cold-rolled steel is not stainless steel, which has poor corrosion resistance and is easy to rust in the wild
Moreover, the fatigue life of the 40Mn cold-rolled steel itself is low, resulting in a low fatigue life of the product

Embodiment 1

[0023] The production method of outdoor sports shoe bottom material of the present invention comprises the steps:

[0024] The first step, material selection

[0025] The 201L1 stainless steel billet of Beihai Chengde Company was selected as the raw material, and it was ready for use.

[0026] The second step, rolling

[0027] Using a rolling mill, the raw material is rolled into a semi-finished steel strip with a thickness of 0.48 mm through two passes of rolling.

[0028] The third step, cleaning

[0029] Pass the rolled semi-finished steel strip through the degreasing and cleaning unit at a speed of 80m / min to remove the rolling oil remaining on the surface of the semi-finished steel strip during rolling.

[0030] The fourth step, a straightening

[0031] The 23-roller tension leveler is used to correct the shape of the cleaned steel strip, and the hardness of the steel strip is controlled at HV400 during the shape correction process.

[0032] The fifth step, stress re...

[0037] The characteristics of the production method of outdoor sports shoe bottom material of the present invention comprise the steps:

[0038] The first step, material selection

[0039] The 201L1 stainless steel billet of Beihai Chengde Company was selected as the raw material, and it was ready for use.

[0040] The second step, rolling

[0041] Using a rolling mill, the raw material is rolled into a semi-finished steel strip with a thickness of 0.52 mm through three passes of rolling.

[0042] The third step, cleaning

[0043] Pass the rolled semi-finished steel strip through the degreasing and cleaning unit at a speed of 100m / min to remove the rolling oil remaining on the surface of the semi-finished steel strip during rolling.

[0044] The fourth step, a straightening

[0045] The 23-roller tension leveler is used to correct the shape of the cleaned steel strip, and the hardness of the steel strip is controlled at HV450 during the shape correction process.

Abstract

The invention relates to a production mode of high-strength high-toughness 200-series stainless steel belts, in particular to a production method for a shoe sole material of outdoor shoes. The shoe sole material of outdoor shoes is prepared by performing rolling, cleaning, primary withdrawal straightening, stress relief annealing and secondary withdrawal straightening on a 201L1 stainless steel blank in sequence. The shoe sole material of outdoor shoes prepared by the method is high in stability, not prone to rusting and long in product fatigue life.

Description

technical field [0001] The invention relates to a production method of a high-strength toughness 200 series stainless steel belt, in particular to a production method of outdoor sports shoe sole materials. Background technique [0002] At present, the sole materials of outdoor sports shoes are all made of 40Mn cold-rolled steel through quenching and tempering process. During the preparation process of quenching and tempering process, in order for the finished product to reach HRC43-47 (to ensure that the sole material has a certain strength and toughness), it is necessary to strictly control the quenching hardness and the uniformity of tempering temperature. However, this is very difficult in the actual production process.
