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

Yagona rulonli po’lat plitalar odatda o’rta qalinlikdagi plitalarga ishora qiladi. O’rtacha qalinlikdagi plitalar prokat va pardozlash paytida tekis plitalar bo’lib, odatda qalinroq (6 mm yoki undan ko’p) va kengligi 4800 mm ga etadi.

Uzluksiz haddelenmiş po’lat plitalar issiq va sovuq haddelenmiş po’lat plitalarga tegishli. Uzluksiz prokatlangan po’lat plitalar prokat oxirida doimiy ravishda o’raladi. Yassilangandan so’ng ular uzluksiz haddelenmiş po’lat plitalarga aylanadi. Kıvırma va tekislash jarayonlari mavjudligi tufayli uzluksiz prokat po’lat uzluksiz prokatlanadi. Plitalar odatda biroz qoldiq kuchlanishga ega va odatda ingichka (25 mm dan kam) (odatda 2100 mm yoki undan kam).

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.
