Title:
HOT-ROLLED STRIP STEEL FULLY-CONTINUOUS PRODUCTION DEVICE AND METHOD FOR FERRITE ROLLING
Document Type and Number:
WIPO Patent Application WO/2021/027908
Kind Code:
A1
Abstract:
Disclosed is a hot-rolled strip steel fully-continuous production device for ferrite rolling, the device sequentially comprising a continuous casting machine (1), a high-pressure water rotating descaling device (2), a four-stand large reduction rough rolling unit (3), a drum shear (4), four thermo detectors (5a, 5b, 5c, 5d) respectively arranged behind the four-stand large reduction rough rolling units, in front of and behind a three- or four-stand finishing rolling unit and in front of down coilers, a multi-functional cold control device (6), the three- or four-stand finishing rolling unit (7), a high-speed flying shear (8), and the down coilers (9a, 9b). The device has a short production line, and a high-pressure water descaling function and an intermediate billet cooling function are integrated into same. The rolling mill arrangement, the four thermo detectors and the short-distance down coilers of the device are used such that the intermediate billet cooling load can be reduced, and accurate temperature control over the process is achieved. Further disclosed is a hot-rolled strip steel fully-continuous production method for ferrite rolling. Based on the method, the energy consumption and the cost are low, the product quality is good, the thickness is small, and the performance requirement of replacing cold with hot can be better met.
