Research And Improvement Of Soft Segments On Dynamic Pressure Calibration System Of Shouqin2#Continuous Casting Machine

With the development of continuous casting technology continues to mature, thequality of continuous casting slab was gradually manufacturers put the first. The internalquality control of continuous casting billet technology--dynamic soft reductiontechnology has become one of the continuous casting machine technology quickly spreadin recent years. At present, generally believe that the light pressure of medium thick slab,slab not only can reduce the effect of thin slab thickness, it is also one of centersegregation and center to reduce osteoporosis means. Dynamic soft reduction techniquecan greatly reduce or eliminate the center segregation and porosity, reduce the internalcracks, but its biggest disadvantage is the relatively high requirements for equipment andcontrol technology, the prerequisite and the dynamic soft reduction equipment maintainaccuracy reliability is prior to use accurate calibration.This paper takes the dynamic Shouqin company2#slab continuous casting machineof soft reduction segments based on the key design segment dynamic soft reduction andprocess, according to the scene production practice summarizes the common fault in thecalibration process of the segment dynamic soft reduction, analyzes the causes of thesefault generated. In order to ensure the reliability of segment dynamic soft reduction, basedon the current use of250mm standard blank online calibration principle, process analysisand summary, the modification scheme was proposed to increase the segment offlinecalibration system, calibration method are given, segment off-line process and significance,and the establishment of the pad as new online calibration block calibration by positioncontrol mode.Renovation of the dynamic soft reduction of continuous casting machine calibrationsystem successfully solves the fault exists in Shouqin company2#slab continuous castingmachine, to ensure the reliability of dynamic soft reduction equipment, to greatly reducethe maintenance time, prolongs the service life of equipment, reduce equipment operatingcosts, ensure the production rhythm which has the significant significance.
