Description
Technical Field
The invention relates to the field of hot-rolled rod and wire production, in particular to a system for checking rolling force energy and calculating a speed ratio of a corresponding gearbox of a hot continuous rolling rod and wire all-line rolling mill based on a B/S framework.
Background
The hot-rolled bar wire comprises a hot-rolled ribbed steel bar and a wire rod which are most widely used and most demanded for buildings, and also comprises a plurality of bar wires such as a mechanical high-quality steel bar and the like. At present, hundreds of common hot rolled bar, high-speed wire and high-speed bar production enterprises exist in China. With the implementation of the new national standard (GB/T1499.2-2018) of the twisted steel, the common hot rolled bar is developed in the direction of mainly reducing the alloy content, controlling the negative tolerance and improving the yield on the basis of meeting the national standard requirement. The high-speed wire rod has high rolling speed, the final rolling speed can reach more than 100m/s, the high-speed wire rod is suitable for producing small-specification hot-rolled wire rods, and the future development mainly takes the aspects of increasing the hourly output of a rolling mill, combining no torsion/micro tension and improving the size precision, the surface quality and the structure performance of products as bursting directions. The high-speed bar is produced by utilizing the high rolling speed of a high-speed wire rod finishing mill, a quick braking system of a high-speed steel feeding system (comprising a tail brake and a rotary hub arranged behind the tail brake) and an independent steel feeding system, so that the requirement of the market on the small-specification straight bar is met, the trouble and waste caused by using a high wire rod circle are effectively avoided, the yield of small-specification products is improved, the defects of low surface quality and low fault yield caused by splitting rolling are reduced, and the high-speed bar is an important production mode for bar production.
With the vigorous market demand and the continuous improvement of the product quality requirement, domestic and foreign iron and steel enterprises continuously upgrade and reform the existing production line, and invest new production lines at home and foreign places to enlarge the market share and competitiveness, thereby gaining market space in fierce competition. The hot continuous rolling rod and wire rolling line generally comprises a rough rolling unit, a middle rolling unit, a pre-finishing rolling unit, a finishing rolling unit and a reducing unit, and simultaneously relates to the independent transmission of a motor and the centralized transmission of one-driven-two frames and one-driven-multiple frames. In the project design planning, the rolling force energy parameters of the production line rolling mill and the gearbox (including a reduction box and a speed increasing box) are necessarily designed and selected according to the productivity requirement and the product characteristics, and particularly the speed ratio of the gearbox is calculated. Reasonable force energy checking and speed ratio selection are beneficial to fully exerting the capability of the motor, the high-speed stable production of a production line is ensured, and meanwhile, enough space is reserved for the adjustment of the rolling speed. Therefore, when designing a complex production line comprising a plurality of transmission modes and a plurality of product specifications, accurate and efficient force energy checking and gearbox speed ratio calculation are of great importance.
At present, the traditional force energy checking and speed ratio calculation mainly uses a plurality of Excel tables, completes the force energy checking of a production line and determines the final speed ratio through a large amount of correlation and iterative calculation. In the checking process, firstly, known basic data needs to be input into the Excel, and all iterations, association relations and calculation formulas are written according to the calculation mode and rules of the Excel table, so that the force energy calculation of multiple passes of a certain product specification is completed; and after the force energy calculation of each pass of a plurality of product specifications is completed according to the same method, the force energy calculation results of all the products in each rolling pass are subjected to statistical analysis and calculation, and finally, the checking data are obtained through sorting and a checking chart is output by using a drawing tool carried by Excel. In the process, a designer needs to adjust a plurality of parameters at any time to meet the checking requirement, and problems are easy to occur in the middle process of calculation, even the problems are difficult to find due to the large data volume and the complex association relation. Any one calculation error needs to be solved by finding the reason among a large number of Excel tables and a large number of data and iteration association relations in a single Excel table by a designer. The method has the main problems that the calculation process is difficult to share, the calculation result is inconvenient to share, new design projects are often required to be recalculated once again, and the workload of designers is huge, the efficiency is low and the error rate is high. The Excel table calculation method has the more prominent defects especially when a complex production line is designed, such as a rolling line formed by compounding common rods and high-speed wires.
