Polycrystalline graphite protective plate plays a protective role in the polycrystalline ingot furnace. It is a two-layer composite structure, one layer is an isostatic graphite material plate that supports the crucible, and the other layer is a graphite carbon felt material that functions as a thermal insulation board.

Graphite card decomposition components: 1, graphite chuck. 2, graphite card cap. 3. Graphite deck. Graphite card flap application area: polysilicon reduction furnace.

Polycrystalline graphite heater has advanced technology, reliable quality, high temperature resistance, oxidation resistance, and strong corrosion resistance. The product life is continuously provided, the production cost is continuously improved, and the production efficiency of the enterprise is improved.

The polycrystalline graphite bottom plate is located under the crucible in the thermal field structure of the polycrystalline furnace, and is close to the graphite side plate on all sides. There is a directional solidification block under the graphite bottom plate.
