Fed by a 90 ton/hr (cold charge) walking hearth reheat furnace, the rolling mill includes a 20 stand continuous mill with two outlets, one for 8 - 32 mm straight reinforcing bar with a slitting scheme and the other for 5,5 - 16 mm wire rod and rebar in coils.
As regards "abnormal" rolling conditions - which are more or less very "normal" for rolling mills - roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll
wide known as the slit rolling technology. This technology as applied to bar mills enables the production of two or more bars from one billet. The slit rolling technology is a combination of spe-cial roll pass design with designated guide Guiding is our business equipment to shape and longitudinally separate the incoming billet into two or more ...
In the continuous bar rolling line of Chongqing Iron and Steel Co., the horizontal and vertical interchangeable rolling mills are adopted for the 16th and 18th stand, so that slitting rolling can be implemented. When rolling 14mm and 16mm ribbed bars, 2-slit rolling is adopted, while 3-slit rolling is used for rolling 12mm Round steel.
First of all, you must design the reinforcement bar rolling for the production of the assured quality product only. The mill will have sequence mix of Roughing, Intermediate and Continuous Mills for quality measurements. Because of this a progressive reduction process, you can produce the bars with uniform size and mechanical properties all ...
Steel - Steel - Billets, bars, and rods: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a three-high mill with box passes, as shown in A in the figure. After a rectangular ...
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...

The continuous casting process for steel is shown in Fig. 1 (second frame) and the close-up of the upper mold region is shown in Fig. 2.In this process, molten steel flows from a ladle, through a tundish into the mold. The tundish holds enough metal to provide a continuous flow to the mold, even during an exchange of ladles, which are supplied periodically from the steelmaking process.
Steel Rolling Mill. Steel Rolling mill is mainly used in steel factory which produce deformed bar, wire rod, channel steel, flat bar or other products.The production line is supposed to use continuous casting billet with size of 150*150*12000mm The allowable tolerance for section dimension of billet should be in accordance with the regulation of YB-2011-83.
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots.Since then, "continuous casting" has evolved to achieve improved yield, quality ...
