The specific embodiment
Describe in detail according to bar controlled rolling and controlled cooling system of the present utility model below in conjunction with accompanying drawing.It will be appreciated by those skilled in the art that specific embodiment described below is only to exemplary illustration of the present utility model, but not for the utility model is carried out to any restriction.
First referring to Fig. 1, steel rolling bar production line generally include heating furnace, roughing, flying shear, in roll, No. two flying shears, finish rolling, No. three flying shears and cold bed.According to the utility model one preferred embodiment, bar controlled rolling and controlled cooling system comprises: the first cooling section 1, and it is arranged between intermediate mill outlet and mm finishing mill unit; Cooling section 4 between machine, be arranged between the finishing mill of mm finishing mill unit, here be pointed out that, all cooling-parts that are arranged between finishing mill are referred to as cooling section between machine, although only show in Fig. 1 therein and be provided with cooling-part between two finishing mills, but it should be understood that cooling-part all can be set between each finishing mill; The second cooling section 3, it is arranged between mm finishing mill unit and No. three flying shears; The 3rd cooling section 4, it is arranged between No. three flying shears and cold bed.
The first cooling section 1, the second cooling section 3 and the 3rd cooling section 4 comprise that respectively cooler, bypass roller-way namely replace roller-way and transverse-moving trolley.
Cooler also can be described as wears hydrophone, it comprises inducer, water-cooled conduit, outlet section, inducer is preferably distributed in the two ends of cooler, water enters water-cooled conduit from two ends, rolled piece directly contacts with water in water-cooled conduit, and carrying out exchange heat, catheter diameter forms the reducing pipe shape of segmentation, thereby realizes fast, evenly cooling.The effect of water exit end is that the water outlet of water-cooled conduit is collected, reduces pressure, discharged.
Bypass roller-way is according to need of production configuration, when not using while wearing water cooling, cooler can be moved apart to rolling line by transverse shifting transverse-moving trolley, uses roller-way that rolled piece is delivered to downstream milling train or cold bed.
Transverse-moving trolley is for switching the online and off-line state of cooler, cooler that simultaneously also can quick-replaceable different size or reveal hydrophone, and the bar of different size generally adopts the cooler of different size, to improve cooling effect and saving water resource.For example, for screw-thread steel bar production, cooler is arranged to five lines to be suitable for cutting technological requirement.
