Abstract
A crucible device with temperature control design includes a crucible body, an induction coil unit, a nozzle flange body and a melt delivery tube and a temperature control unit. The induction coil unit surrounds the crucible body, provides a heat source during use, and is configured to enable a metal material to melt and produce a melt having a melting skull. The melt delivery tube is communicated via the nozzle flange body to a bottom of the crucible body and is configured to deliver the melt from the crucible body. The temperature control unit includes a microprocessor, a heater and a temperature sensor which are electrically coupled to each other, and are configured to control a curve of the melting skull to drop to a preset position.
Claims10
A crucible device with temperature control design, wherein the crucible device comprises:
- a crucible body;
- an induction coil unit, surrounding the crucible body, providing a heat source during use, and configured to enable a metal material to melt and produce a melt having a melting skull;
- a nozzle flange body and a melt delivery tube, wherein the melt delivery tube is communicated to a bottom of the crucible body via the nozzle flange body, and is configured to deliver the melt from the crucible body;
- and
- a temperature control unit, comprising a microprocessor, a heater, and a temperature sensor that are electrically coupled to each other, wherein:
- the temperature sensor is configured to measure a temperature of a boundary of the nozzle flange body which is close to the melt, the heater is configured to inductively heat the nozzle flange body, and the microprocessor adjusts a power of the heater according to the measured temperature of the boundary of the nozzle flange body, so as to control the temperature of the boundary of the nozzle flange body to reach a predetermined temperature, and to further control a curve of the melting skull to drop to a preset position.
A temperature control method for a crucible device, comprising the following steps of:
- providing a crucible body, a nozzle flange body, and a melt delivery tube, wherein the melt delivery tube is communicated to a bottom of the crucible body via the nozzle flange body;
- inductively heating an active metal material rod inside the crucible body, to produce a melt formed with a melting skull;
- measuring a temperature of a boundary of the nozzle flange body which is close to the melt;
- and
- inductively heating the nozzle flange body according to the measured temperature of the boundary of the nozzle flange body, and controlling the boundary of the nozzle flange body to reach a predetermined temperature, wherein:
- when a temperature of the melting skull of the melt is more than a temperature at which the nozzle flange body reacts with the melt to produce a compound, the predetermined temperature is less than the temperature at which the nozzle flange body reacts with the melt to produce a compound;
- and
- when a temperature of the melting skull of the melt is less than a temperature at which the nozzle flange body reacts with the melt to produce a compound, the predetermined temperature is less than the temperature of the melting skull of the melt.
