Released on: September 6, 2020 17:47:34
Recently, the world's first fully automatic light rail universal continuous rolling production line with independent intellectual property rights invested and built by Hebei Yongyang Special Steel Group Co., Ltd., the first in China, passed the steel smoothly, and the test run was successful. After the inspection, the product section size and surface quality were all qualified. The performance index of the mill and the fully automatic steel rolling control system were stable, and more than 30 qualified products were continuously produced.
The automatic light rail universal continuous rolling production line innovatively adopts the "2+7" light rail semi continuous rolling process route, realizes the intelligent pre bending, cooling, straightening and online automatic finishing of light rail, and creates a new production process mode of light rail production; At the same time, it is equipped with the first intelligent light rail long cooling bed in China, and has adopted the self-developed intelligent pre bending technology of long light rail, air cooling and water mist cooling double strong cooling technology, intelligent steel tapping technology and other advanced technologies. It has reached the domestic leading level in terms of yield, comprehensive operation rate, power consumption per ton of steel, per capita steel output, quality improvement and environmental protection improvement.
In recent years, Hebei Yongyang Special Steel Group Co., Ltd. has made use of the technology platform of the R&D center and the construction innovation center to strengthen cooperation with the General Institute of Iron and Steel Research, Beijing University of Science and Technology and other scientific research institutes, improve the product R&D capability, and continuously developed high-quality and high added value special steel products such as automobile steel, high-strength fastener steel, bridge steel, oil mining steel, supercritical and ultra supercritical high pressure boiler billets, Strive to build a domestic production base for high-quality rail steel and high-quality special steel.
The successful full-automatic light rail universal continuous rolling production line in this trial run is positioned in the production and application of special section steel products such as light rail, elevator rail, industrial track and mining I-beam. The core technology adopts two BDCD bloom rolling mills and seven UMCD universal rolling mills processed and manufactured by MCC CCID with full independent intellectual property rights in China. The universal mill adopts a high rigidity arch structure and advanced TCS process control system. It integrates automatic gap control (AGC) and hydraulic position control (HPC) for the first time, applies intelligent high-precision universal section mill to the continuous section rolling production line, and realizes the efficient production of high-precision light rail, H-beam, mining section steel and other products. This technology subverts the backward process of the traditional horizontal section steel production line, solves the process defects of the fixed roll gap rolling method of the short stress line universal mill, realizes the adaptive control of pass and micro tension in the production of special section steel, improves the automation and intelligent level of the rolling process, and improves the comprehensive quality and production efficiency of the product.
