Product Description

Performance   :High density, High hardness, High temperature resistance, High pressure resistance, Corrosion resistance, Good conductivity and stability.
      In the multi-crystal furnace, the graphite heater is the main hot one in the process of polysilicon ingots, its size, position and quality seriously affect the quality of polysilicon.
Polysilicon ingot furnace is mainly used for manufacture of polycrystalline silicon solar photovoltaic industry, synthetic polycrystalline furnace thermal field system is composed of a variety of graphite material device, one of the most core component is the graphite heater, polycrystalline furnace graphite heater is composed of 99.99% graphite casting.
      Polycrystalline furnace thermal field according to the size of the polycrystalline furnace graphite heater, graphite material, size, were selected, and the graphite heater is the main heat source of growth of polycrystalline furnace, so the quality of the graphite heater directly affect the quality of the thermal field polycrystalline. In the production of graphite heater, the supplier has to carry out layers of checks from graphite material to final logistics.
Note: To do well before the use of the inspection work, and after the use of cleaning work, if there is a bad reaction in the multi-crystal furnace should be repaired immediately, so as not to cause greater loss.
We can produce graphite heater, graphite crucible, graphite tray, graphite anode, graphite electrode cover, graphite fasteners, etc.

The following schedule is the main specifications  of our graphite produces.According to your drawings, specifications and physical and chemical indicators, we will customize the products you need.
