style=\"font-size: 16px;\">1. Cold rolled strips could be very thin, reaching to 0.001mm. This is hard to be achieved by hot rolling.<\/span><\/p><p style=\"color: #333333; font-family: sans-serif, Arial, Verdana,;\"><span style=\"font-size: 16px;\">2. The end products have advanced and widely used mechanical and process properties.<\/span><\/p><p style=\"color: #333333; font-family: sans-serif, Arial, Verdana,;\"><span style=\"font-size: 16px;\">3. Cold rolled strips have highly accurate dimension, little deviation in thickness, good shape, and smooth surface.<\/span><\/p><p style=\"color: #333333; font-family: sans-serif, Arial, Verdana,;\"><span style=\"font-size: 16px;\">4. Low cost while high output.<\/span><\/p><p style=\"color: #333333; font-family: sans-serif, Arial, Verdana,;\"><span style=\"font-size: 16px;\">5. Fast speed of rolling with high productivity.<\/span><\/p><p style=\"color: #333333; font-family: sans-serif, Arial, Verdana,;\"><span style=\"font-size: 18px;\"><strong>Process characteristics of cold-rolled strips:<\/strong><\/span><\/p><p style=\"color: #333333; font-family: sans-serif, Arial, Verdana,;\"><span style=\"font-size: 16px;\">1. When cold rolling is taken, the strips will be harden during processing. Thus, quenching is necessary to soften the strips so as to restore the flexibility for continuous rolling.<br \/>2. Clean the scale on the surfaces of strips before rolling in order to keep the surfaces smooth as well as to reduce abrasion of rollers.<br \/>3. Apply tension rolling to guarantee strips in good shape, to control the deviation in thickness, and to reduce rolling pressure for the benefit of thin strip rolling.<br \/>4. Apply process cooling and lubrication to easily control the temperature of rollers and strips, and to reduce the abrasion between rollers and strips, as well as reduce the rolling pressure, so as to properly control shape of strips and prevent them from roll banding. Cold-rolled strips and steel plates are generally 0.1~3mm thick and 100~2000mm wide, made of hot rolled strips or steel plates by means of cold rolling mill. They are of smooth and clean surface, accurate dimension, and good mechanical properties. Most of the cold-rolled strips and steel plates will be made into coils, or coated with oil painting as colored coated sheets. Coiled cold-rolled steel sheets have high productivity and are easy to use and be processed. The production of cold-rolled strips and steel sheets occupies 30% of total production of steel products in developed industrial countries. In addition to the common carbon steel, steel grades include silicon steel, stainless steel, alloy steel, and etc.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Strip mill lines Strip steel rolling mill line: Strip s &hellip;<\/p>\n<p class=\"read-more\"> <a class=\"\" href=\"http:\/\/www.rollingmill.net\/?page_id=574\"> <span class=\"screen-reader-text\">Strip mill lines<\/span> Read More \u00bb<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":548,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"elementor_header_footer","meta":{"site-sidebar-layout":"no-sidebar","site-content-layout":"page-builder","ast-global-header-display":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"disabled","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","footnotes":""},"class_list":["post-574","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"http:\/\/www.rollingmill.net\/index.php?rest_route=\/wp\/v2\/pages\/574","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/www.rollingmill.net\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"http:\/\/www.rollingmill.net\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"http:\/\/www.rollingmill.net\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.rollingmill.net\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=574"}],"version-history":[{"count":0,"href":"http:\/\/www.rollingmill.net\/index.php?rest_route=\/wp\/v2\/pages\/574\/revisions"}],"up":[{"embeddable":true,"href":"http:\/\/www.rollingmill.net\/index.php?rest_route=\/wp\/v2\/pages\/548"}],"wp:attachment":[{"href":"http:\/\/www.rollingmill.net\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=574"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
