The experiment used in crystallization stirrer @ IDEA electric

             In terms of ac induction method,the basic structure of an electromagnetic stirrer is actually a can stimulate the magnetic field sensor, it is similar to electrical machine’s stator, the molten metal is equal to the rotor. The magnetic field creative by inductor act on the molten metal inside the crystallizer, and have relative movement with the molten metal, the molten metal is electric conductor, so, it will produce induced current in it, the current interact with the magnetic field produce by inductor to produce electromagnetic force, which drive metal fluid movement. The way of movement is determined by the magnetic field, at present, the widespread application of magnetic field are rotating magnetic field and traveling wave magnetic field.                       Compared with other mixing way, electromagnetic stirring compatible with the other mixing way’ advantages, and has its own unique characteristic, therefore, electromagnetic stirring has become the common use stirring method.               Effect of stirring               To adopt the advanced technology of electromagnetic stirring, through lots of experiments and industrial production at home and abroad by using electromagnetic stirring main effect achieved:             Reducing slag content;             Reduce the center shrinkage cavity;             Eliminate the macrosegregation;             Increase the equiaxial crystal ratio;             Improve solidification organization, etc.                 Quality assurance commitment                The whole equipment warranty for one year, in the warranty period all equipment failure caused by the product quality, we will unconditionally solutions within 48 hours or sent to the scene to solve. If due to improper use or accident situation of equipment failure, we should solve immediately, but the buyer need to bear the cost.               Supply period              A complete set of equipment supply cycle for 3 months, installation and debugging time for two weeks; imported spare parts supply cycle to be less than three weeks, domestic supply of spare parts for 1 week, my company produced parts supply cycle to be less than 2 weeks.              Technical service commitment               Our company will provide details of the whole equipment use, along with the equipment operation and maintenance instruction manual, main circuit and the principle of high voltage control circuit diagram and wiring diagram, functional block diagram and program flow chart. Our company will be responsible for the whole set of equipment installation and debugging, but the buyer need relevant technical personnel on-site to cooperate, after completion of the installation and debugging, we will cooperate with buyer's technical personnel for the equipment operating and maintenance procedures, and make the buyer's relevant people on-site technical training.
