吉林十一选五分布走势图 www.orvwgm.com.cn Since May this year, Hebei Iron and Steel steel mill vanadium steel rolling plant in the implementation of equipment, process management process, focusing on strengthening the 1780 mill gap micro-scale control level, by taking the thickness of the arch liner And the adjustment of the stiffness between the rolling mill is less than 30t / mm2, the deviation of the horizontal value is controlled at 0.4mm, the rolling force deviation is stabilized within 40 tons, and this index reaches the industry Leading level.
It is understood that with the increasingly fierce competition in the coil market, thin specifications of the coil has the advantages of use and price advantage has become increasingly prominent, how to reduce the rolling mill in the process of maintaining the stability of the rolling mill, Of the bottleneck, for this phenomenon, steel mill to mention vanadium steel rolling mill selection difficulties, set up a "optimization of rolling mill gap micro-scale control technology" research group, focus on superior forces to focus on breakthroughs. In the process of research, the plant according to the rolling mill stiffness value, level value, rolling force deviation and displacement sensor and other data changes, indirectly derived from the roll center line of the relative cross; by adjusting the thickness of the mill liner and arch window width, The rolling mill gap is controlled by micro-scale, the relative position of the roll in the arch is optimized, the phenomenon of the center line crossing of the roll is solved, the synthetic gap is optimized, the optimum clearance value is explored, and the reversal of the bearing seat in the arch is avoided. System process stability.
With the continuous deepening of the research process, the proportion of steel plate 1780 production line thin coil ratio increased by 13.68%, of which 2.0mm below the very thin product specifications to achieve mass production capacity, equipment accuracy and process technology has been further refined and Innovation.
According to the relevant sources said the plant is the use of imported magnetostrictive displacement sensor to control the accuracy of the current foreign well-known brands are: MTS, Baruofu, De Min Zhe and other products, the company is the German distributor of Germany, welcome Our customers inquiry.
