Description

The directional solidification furnace is used for the hot liquid silicon solidification and purification.

The working principle is as following: under proper condition, the liquid silicon will flow through the  diversion trench or tundish to a pre-heated crucible for pouring and casting. The heating power supply will generate great amount heat and make the temperature to the directional solidification temperature. The liquid metal flows down from the bottom of the induction furnace at a stable speed, and under the protective gas, the liquid is precisely controlled for crystallized by the lift, thus achieve the goal of purification.

Adopt electron-magnetic induction principal, quicker heating, less burning loss, lower labor strength, better good quality.

The whole system adopts full digital control which can realize power factor calibration, constant power control, temperature control, frequency tracking, zero power start-up, real-time monitor on over-current and over-voltage faults, alarm display etc.

Quick IGBT drive circuit which can significantly improve the wave of the resonance, reduce the time of dead zone and decrease the loss of switch.

Adopt diode whole bridge rectification which has little impact on the resonance of the grid.

Adopt the superior non-polarity thin-film capacitor, the middle frequency coupling transformer is composed of micro-crystalline material which ensure the safe operation, easy match and convenient adjustment, wide scope of loading.

The vacuum induction smelting furnace is made of the column furnace body, furnace lid, temperature detecting mechanism, vacuum system, insulation heating system, furnace discharge chamber, pneumatic control system, cooling water system, working platform, smelting power supply, hydraulic system.

The furnace body adopts double cooling water structure which can effectively cool down the furnace body. There is anti-explosive valve on the body which has the function of explosion protection and decompression.

Competitive advantage

High control precision.

Free adjustment on the speed of crystallization.

Directional solidification heat-resistance furnace adopts special heating power supply which is of 3 phases current balanced.

Low cost on maintenance.

Constant temperature controller which can set 148 heating temperature technology curves.

Furnace chamber adopts vacuum chamber which is of high vacuum and quick air exhaust.
