Exploitation On The Production And Technique Software Of Hot Plate Rolling In Single Roller

The optimizes to the billet design of the the medium slab turn to commence, theanalyze various factor that influence the useful rate exaltation, and put the method that thereasonable billet design; Then anticipate to carry on production according to the differentbillet to give the each reasonable arrangement; And combine the spot experiencephysically of plate, while guarantee the safety of the equipments, with attain high becomeuseful the rate, high size accuracy and high performances, low consume, the rolling steel ofthe quick rhythm produces for the purpose to draw up new rules of deformation; Throughresearch recrystallization in austenite rule of 16MnR to imitate calculation the organizationto the medium plate after rolling and cooling, carrying on the forecast the tiny vieworganization and macroscopic functions of the plate; The calculation of the rolling poweradopts to consider the variety of the recrystallization in austenite the correction function,improve the accuracy forecast of power and energery; The thesis with foundation ofequipments, craft condition of the plate steelworks of HanDan, in studying variouscalculation model and method of foundation, investigated a software of in hot plate rollingand got as follows as a result:1. The billet design of plate according to rolling, it can decrase the non-quality goodsabout 7 percent in "single fix ruler plate", improve the useful rate about 1.25 percent in"mix-rolling plate"and about 0.46 percent in "double fix ruler plate"in the thesis.2.It can get the economic and technic target of production of team every day, arrangeproduction plan in reasonable and examine the production team.3.Design of optimize deformation rule in this research almost including all of thetechnology in medium plate rolling, theory relation practice is it's specialty and high usefulrate and dimension precision and good property and low power and fast production is it'starget in rolling. Practice shows that the rule achieves the intention of "more, quickly, welland save"in plate production. For example, if take specification as 16MnR to arrangeproductin can improve the production efficiency about 15.37 per in the thesis.4. Through the research on recrystallization disciplinarian in 16MnR of medium plate,the results are agreed well with measurement value. It shows that it is feasible wheninvestigative model is used in plate continuous product line. Through the computersimulation and prediction of changed structure field and on property controlled-coolingaustenite show that the resul are basically agreed with the measurement result throughmetallurgical micro-observation. 5. The influence of remnant strain because of not enough austenite recrystallization onrolling load is considered in computing of rolling force in plate, it can obviously improvethe predicting precise. The predicted thickness of work piece is also accorded with themeasurement value using the force result.
