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

Ib leeg-dov steel ntawv feem ntau yog xa mus rau nruab nrab-tuab daim hlau. Cov phaj tuab tuab tau ua cov phaj tiaj tiaj thaum dov thiab ua tiav, feem ntau yog tuab (6mm lossis ntau dua) thiab qhov dav yog ceev li 4800mm.

Nruam dov cov ntawv hlau xa mus rau cov ntawv kub-dov thiab txias-kuav los tiag steel nplooj ntawv. Nruam-dov cov nplooj ntawv steel yog txuas ntxiv dov thaum kawg ntawm dov. Tom qab flattened, lawv ua nruam dov steel nplooj ntawv. Vim muaj cov txheej txheem curling thiab flattening, nruam dov steel yog txuas ntxiv dov. Cov phaj feem ntau muaj qee qhov kev ntxhov siab thiab feem ntau yog nyias (tsawg dua 25 hli) (feem ntau yog 2100 hli lossis tsawg dua).

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.
