Graphite furnace block, I plant the production of high-temperature furnace body with graphite blocks, graphite bricks, can also be customized for the user processing of a variety of graphite plate, graphite grooves and other graphite products. Our factory graphite products with high density, antioxidant, corrosion resistance and so on
Feature of Special Graphite Products
The demand from industry over the years has been for carbon with increasingly tighter and stable properties. we produced the isostatic graphite products tested National Electric Carbon Products Quality Supervision and Inspection Center, the main physical and chemical properties have reached: compressive strength 125MPa, a Shore hardness of 65 degrees, the resistivity 12μΩm. Is the only country capable of producing more than 800mm diameter, particle size less than 18 microns large-sized enterprise isostatic graphite products, make up the domestic market blank large size of graphite products, products by customer applications, good performance, to meet the needs and improve the domestic and other isostatic graphite products share. While being 10μm trial following products, has entered the small-scale production; more high quality isostatic specialty graphite finished rate of 90%, far ahead of the industry's yield of 70%, living first in the country.
The application for this grade is specific to industries and applications like:
(1) Diamond Tool Pressure Sintering
(2) Die Moulds
(3) Continuous Casting Dies for Aluminium, Copper and Brass
(4) Degassing Rods
(5) Crucibles and Sealing Rod
(6) Semi Conductor applications
(7) Solar Technology applications
(8) EDM Applications
Product Advantage
1. Thermal stability: according to the use conditions of hot and cold products, special design is made to ensure the reliability of product quality.
2. Erosion resistance: the uniform and fine matrix design delays the erosion degree of the product.
3. Impact resistance: the product can withstand high thermal shock strength, so any process can be assured.
4. Acid resistance: the addition of special materials can significantly improve the quality of products, show excellent performance in acid resistance index, and greatly extend the service life of products.
5. High thermal conductivity: high content of fixed carbon ensures good thermal conductivity, reduces dissolution time and significantly reduces energy consumption.
6. Control of metal pollution: strict control of material composition ensures that the product does not pollute the metal when dissolved.
7. Quality stability: the manufacturing technology and quality assurance system of high pressure forming can more fully guarantee the quality stability.
