The difference between single rolled steel plate and continuous rolled steel plate

單軋鋼板通常是指中厚板。 中厚板在軋製和精整過程中一直是平板，通常較厚（6mm以上），寬度最快可達4800mm。

連軋鋼板是指熱軋和冷軋鋼板。 連軋鋼板在軋製結束時連續軋製。 在被壓扁後，它們成為連續軋製的鋼板。 由於捲邊和壓扁過程的存在，連軋鋼是連續軋製的。 這些板通常有一些殘餘應力並且通常更薄（小於 25 毫米）（通常為 2100 毫米或更小）。

Hot-rolled steel sheets and strip products are made of slabs (mainly continuous casting billets), which are heated to form strips from roughing mills and finishing mills. The hot steel strip from the last rolling mill of the finishing mill is cooled to a set temperature by laminar flow, rolled into a steel coil by a coiler, and the cooled steel coil is subjected to different finishing operations according to different needs of users. Lines (flat, straight, cross-cut or slit, inspection, weighing, packaging and marking) are processed into steel, flat and slit steel strips. Because hot-rolled steel sheet products have high strength, good toughness, easy processing and good weldability, they are widely used in ship, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries. With the increasing maturity of new technologies such as hot-rolling dimensional accuracy, plate shape and surface quality, and the advent of new products, hot-rolled steel sheets and strip products have become more and more widely used and are becoming more and more powerful in the market. Competitiveness. Generally speaking, hot-rolled steel products have a wide variety of specifications and applications. From general engineering structures to automobiles, bridges, ships, boilers and pressure vessels, they are widely used. For various purposes, the requirements for the material properties, surface quality, size and shape accuracy of the steel sheet are also different. Therefore, it is necessary to understand the varieties, materials, characteristics and uses of the hot-rolled steel sheet products in order to achieve economical efficiency. Reasonable use.
