The “DAI SYSTEM P7” equipment allows automatic dispensing of the inoculant material into the pouring stream just before it enters the mould. In this way the maximum effect of the inoculation is assured, since fading is avoided and uniformity of treatment is ensured. Pouring stream inoculation enhances the casting quality and reduces process costs.

The equipment is PLC controlled with the possibility of adapting the control program to the Client specific needs. The “screw-type” dosing system permits the use of various types of inoculating materials in a wide range of densities and sizing. The operator can set the quantity delivered directly in gr./sec. Because of the excellent thermal insulation, the dosing unit can be installed close to the pouring unit.
CONTROL UNIT
P7-10s
TECHNICAL CHARAC TERISTICS - Single cable connection between the control unit and dosing unit - Repeatability better than +/- 2 % - Stainless steel case and hopper containing the inoculant, approx. 30 kg standard capacity, with minimum level detection sensor - Display and settings directly in flow rate “gr/sec� format - Easy calibration procedure - Calibration cur ves according to the specific material - Three calibration cur ve can be stored and recalled - Electro pneumatic pressure regulator: the thrust pressure is adjustable by the HMI operator panel (no need adjust on hotbox side) - Interchangeable feed pipe - Clogged pipe checking by ver y reliable and pressure control system - Ethernet inter face with peripheral systems (Standard for Siemens and A&B PLC, optional with other PLC brand) - Continue temperature monitoring and preset alarm. (by using a thermocouple sensor) - Adjustable capacity from 0,1 to 30 gr./sec (exactly range depends on screw type) *Different dosing ranges can be done upon customer request - Optional: Outflow pipe alignment control *, by infra-red sensor (IRD-05 sensor
