CN109321830A 一种高塑韧性与高平直度的高碳钢板及其制造方法 无效 - 驳回

一种高塑韧性与高平直度的高碳钢板及其制造方法
摘要：
本发明属于钢铁生产技术领域，尤其涉及一种高塑韧性与高平直度的高碳钢板及其制造方法。本发明所述的一种高塑韧性与高平直度的高碳钢板的制造方法，包括以下步骤：冶炼——精炼——连铸——板坯下线缓冷——热装热送——粗轧——精轧——层流冷却——钢卷缓冷——卷取——横切开平。与现有的高碳钢热轧带钢生产技术不同，本发明采用控轧和控冷工艺来生产，显微组织上形成了细小的稀片层珠光体与退化珠光体搭配分布的显微组织。本发明所述的高塑韧性与高平直度的高碳钢板相比于现有产品，硬度更低，塑韧性更高，平直度更优良。
摘要（英）：

The invention belongs to the technical field of steel production, and particularly relates to a high-carbon steel plate with high plastic toughness and high straightness and a manufacturing method ofthe same. The manufacturing method of the high-carbon steel plate with the high plastic toughness and the high straightness comprises the following steps of smelting, refining, continuous casting, steel slab off-line slow cooling, hot mounting and hot feeding, rough rolling, finish rolling, laminar cooling, steel coil slow cooling, reeling and transverse cutting. Compared with the existing high-carbon steel hot-rolled strip steel production technology, the high-carbon steel plate is prepared by adopting a controlled rolling and controlled cooling process, small thin-sheet-layer pearlites and degraded pearlites distribute on a microscopic structure in a match mode. Compared with an existing product, the high-carbon steel plate with the high plastic toughness and high straightness has the advantages that the hardness is lower, the plastic toughness is higher, and the straightness is better.
