Description
Technical Field
The utility model belongs to the technical field of steel rolling equipment, concretely relates to prevent device of thin specification high-strength steel flat roll.
Background
With the continuous research on 'replacing cold with heat' on thin strip products in recent years, most thin slab continuous casting and rolling lines (such as FTSR, CSP, ESP and the like) successively develop thin-gauge low-carbon high-strength low-alloy steel products, and the thinnest thin steel can be rolled to 0.7 mm. The low-carbon high-strength low-alloy steel produced by adopting the controlled rolling and controlled cooling process is particularly suitable for general stamping and welding processing due to high strength and good weldability and cold forming performance, and is widely applied to the industries of machinery, automobiles and the like. However, the reduction in the thickness of the strip causes difficulties in coiling after hot rolling, and the problem of the thin gauge strip being rolled flat or even collapsed occurs. The steel coil is difficult to further process due to serious deformation, and cannot be directly uncoiled in subsequent flattening, pickling and cold rolling processes; or unwittingly uncoil, but have to assist additional equipment or increase cutting loss and waste; even the whole roll of the strip steel is damaged and rejected under severe conditions.
For the problem of flat coil in the thin strip hot rolling process, a process optimization or mechanical mode is generally adopted, and the process mainly comprises the steps of changing coiling temperature, coil unloading time and the like; the mechanical mode is through changing the stress state of coil of strip when the coiling, prevents the flat book for the coil of strip provides extra holding power.
CN102335681A discloses a coiling method for preventing flat coiling of hot-rolled strip steel, and discloses a coiling method suitable for steel grades with 0.02-1.0% of C, 0.3-1.5% of Si, 0.5-3.0% of Mn, less than or equal to 1.0% of Cr and the like, which adopts two-stage coiling: in the first stage, strip steel is rolled out of a finishing mill, is cooled by laminar flow and then enters a coiling machine for coiling, wherein the coiling temperature is 500-600 ℃; and in the second stage, the coiled steel coil stays on the coiling machine for 20-60 s. By adopting the method, flat coiling can be effectively avoided, but the brittleness of the high-carbon steel strip is increased due to low-temperature coiling, the steel plate is easy to crack and the like, the strength is high, the subsequent processing is difficult, and in addition, the coiling drum stays for 20-60 s, so that the production efficiency is greatly reduced.
CN206122342U discloses a method for supporting the inner wall of a hot-rolled coil by two arc cushion blocks. The device not only can effectively prevent the hot-rolled coil from having the flat coil defect, but also can not cause any damage to the surface of the steel coil, but the coil temperature of the hot coil is very high, and the danger coefficient of the device is larger during the actual operation.
In conclusion, the process optimization needs to change the existing components, and the production cost and the production efficiency are influenced. The mechanical mode can prevent flat rolls from being generated under the original component system, but the hot roll adding device needs to prevent and control operation risks.
