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

 

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

Lembaran baja canai tunggal biasanya mengacu pada pelat dengan ketebalan sedang. Pelat dengan ketebalan sedang telah menjadi pelat datar selama penggulungan dan penyelesaian, biasanya lebih tebal ( 6mm atau lebih) dan lebarnya secepat 4800mm .

 

Lembaran baja canai terus menerus mengacu pada lembaran baja canai panas dan canai dingin. Lembaran baja canai terus menerus digulung terus menerus pada akhir penggulungan. Setelah diratakan, mereka menjadi lembaran baja yang digulung terus menerus. Karena adanya proses pengeritingan dan perataan, baja penggulungan menerus terus menerus digulung. Pelat biasanya memiliki beberapa tegangan sisa dan biasanya lebih tipis (kurang dari 25 mm) (biasanya 2100 mm atau kurang).

 

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.
