百度中的带钢简介（Introduction of strip steel in Baidu）

百度中的带钢简介（Introduction of strip steel in Baidu） Cold strip editing The thickness of cold rolled strip and sheet is 0.1 ~ 3mm, and the width is from 100 to 2000mm. The products are made of hot rolled strip or steel plate and rolled in cold rolling mill at room temperature. Catalogue 1 Introduction 2 shape 1. Brief introduction to cold rolled steel strip and cold rolled steel strip The thickness of cold rolled strip and sheet is 0.1 ~ 3mm, and the width is from 100 to 2000mm. The products are made of hot rolled strip or steel plate and rolled in cold rolling mill at room temperature. Cold rolled strip and sheet have the advantages of smooth surface, smooth surface, high dimensional accuracy and good mechanical properties. Most of the products are formed into rolls, and a large part of them are processed into coated steel plates. The roll cold rolled sheet has the advantages of high production efficiency, convenient operation and favorable follow-up processing. Therefore, widely used, it has gradually replaced the same thickness of hot rolled sheet. Only a small number of cold rolled alloy sheets for special purposes are rolled by single plate. The production of cold rolled strip and sheet steel accounts for about 30% of the total output of steel in developed countries. In addition to ordinary carbon steel, there are silicon steel, stainless steel and alloy structural steel, etc.. 2 shape edit edge wave: When the wave length is not less than 200mm, the nominal width of less than 1500mm steel, the wave length of the wave height should be less than 1%, the nominal width of not less than 1500mm of steel, 1.5% wave height should be less than the wave length. When the wave length is less than 200mm, the wave height should be less than 2mm. [1] Sickle bend The bending of the steel plate and the steel band shall be no more than 5mm on any length of 2000mm. When the length of the steel plate is not greater than 2000mm, the bending of the sickle shall be no more than 0.25% of th
