Research On The Automatic Feeders Of Slag Mold

Mold powder is the key material of metallurgy to ensure producing qualifiedcontinuous casting slab. In actual production, whether the physical and chemicalproperties of slag can effectively bring into play is bounded up with the powder.addingoperation. Automatic feeders technology can accurately achieve slag layer thickness anduniformity velocity of powder adding, which is difficult to achieve by manually addition.Therefore, automatic feeders can effectively reduce slab surface defects and improve thepassing rate of the slab. In term of this purpose, I developed a slab mold guide spacetwo-body Automatic feeders to achieve process of powder adding automation, controlled,and precision.The mechanism of mold powder lubrication has been analyzed deeply. It hasprovided proof to design and exploit slab mold automatic feeders by summing up slabmold powder adding standard. According the powder adding request, I design a type ofautomatic feeders, in the same way I built the mathematical model of powder addingtrajectory. The automatic feeders make up with space dual guide rod parallel mechanism.The purpose of horizontal guide mechanism is to make spiral conveying pipe swing on themold. The function of vertical guide mechanism is to achieve displacement compensation.Through combine the two mechanism, lead the locus of spiral conveying pipe toapproximate straight line.The model of trajectory has been optimized by application of genetic optimizationalgorithm and MATLAB genetic algorithm toolbox. The optimization results has showedthat powder has been added track width of the mold surface with the smallestdisplacement error. In order to achieve uniform velocity on the trajectory of powderadding, the mathematics control theory has been established through the analytical method,and graphical method. The key transmission parts of automatic feeders are establishedthrough using of Pro/E and virtual assembly model of automatic feeders is built,connection detection of the assembly model certificated that the structural design ofautomatic is right. The locus and velocity of powder adding has been analyzed dynamically by using simulation module of Pro/E. The results demonstrated that thedesigned automatic feeders can realize approximate straight line locus and uniform addingvelocity.
