本发明涉及一种高强钢带钢的加工工艺，包括如下步骤：选取牌号为SCM435的热轧卷板；将进行第一次纵剪分条；将第一次纵剪分条的热轧卷板通过退火炉/氨分解炉进行软化退火，制得软化退火卷板；将软化退火卷板进行酸洗，并制得酸洗卷板；将酸洗卷板进行轧制，并制得轧制卷板；将轧制卷板通过退火炉/氨分解炉进行球化退火，制得球化退火卷板；将球化退火卷板进行精轧，并制得精轧卷板；将精轧卷板通过小分条机进行第二次纵剪分条，并制得分条卷板；包装入库、利用打包机对分条卷板进行打包包装。本发明的有益效果是：能够稳定产品质量、提高劳动生产率。 The invention relates to a machining technology for strip steel. The machining technology comprises the following steps that a hot-rolled rolling plate with the mark number of SCM435 is selected; the hot-rolled rolling plate is subjected to first-time longitudinal shearing splitting; the hot-rolled rolling plate obtained after first-time longitudinal shearing splitting is subjected to softening annealing through an annealing furnace/ammonia decomposition furnace, and a softening annealing rolling plate is manufactured; the softening annealing rolling plate is subjected to acid pickling, and an acid pickling rolling plate is manufactured; the acid pickling rolling plate is rolled, and a rolled rolling plate is obtained; the rolled rolling plate is subject
