Series semi-solid electromagnetic stirrer 2016

                    System Over View:             1,The system adopts IPM intelligent power module as the core device, itself has a short circuit, over-current, overheating, under-voltage protection function, in the design of the system add a reliable buffer circuit and other anti-interference circuit.             2,Using industrial-grade single-chip computer as core control, it can be adapted to the harsh industrial field, data collection is accurately, processing speed is fast.             3,Switch, contactor, rectifier, filter, buffer circuits and other electronic devices, all choose the reliable device, in the design choose the larger pressure, flow, coefficient of thermal protection.             4,As far as possible in the structure design and manufacturing to reduce the distributed capacitance and inductance and raise resistance to radiation, induction and coupling interference ability.             5, Parameters and program design strictness, system logic inputs and downtime, can better prevent system damage caused by the error operation and forced outage.                         Basic function:             1,have the input voltage, output current dial indicator, working frequency, working voltage digital indicator.             2,Current and frequency in setting within the scope of work infinitely variable control.             3,System in the mixing state can be changed by adjusting the voltage working current.             4,The system is equipped with continuous and time setting two kinds of working mode, under any mode it have clockwise stirring, anticlockwise stirring and automatic mixing the three kinds of mixing way, any stirring condition the mixing time, stop time, commutation stop time can be within the scope of the parameters set arbitrary.             5,Fault indicator is divided into system outage, mixing stop failure and alarm failure three categories.             A, System outage: including the cooling fan failure, the IPM module failure, rectifier fuse failure, main contactor of failure and the control of the power failure, etc.             B, mixing stop failures: Including: a serious shortage of water, agitator winding serious overheating, the cooling fan stop.             C, Alarm failure: including the shortage of water flow and water pressure, over-current and under-voltage unbalanced three phase current, etc.                 In a word, The semisolid continuous casting technology in high alloy material, difficult deformation, fine crystal homogenizing steel materials and high value-added new materials forming has a unique technical advantages.               System advantages             In order to convenient for laboratory research, in the sensor’s the relationship between semi-solid metal stress and the dendrite. This system adopts the voltage, frequency, stirring time continuously adjustable, made the semi-solid metal liquid loading condition be clear at a glance. Simple operation control interface, the man-machine interface simple and clear, all operations on the control panel can be done immediately.
