How It Is Used<\/h2>\n <\/hgroup>\n

\n Taking advantage of graphite’s excellent heat resistance and thermal shock resistance, graphite is used in all types of metallurgical components including molds, dies, slip plates, crucibles, boats, funnels, sliding plates, and cooling frames.
\n Representative examples of graphite molds include molds for electroformed bricks used in casting glass and LCD panels. The common method involves machining graphite to create molds and pouring molten glass into them.\n <\/p>\n

\n Electroformed bricks are products cast using graphite molds.
Electroformed bricks are extremely dense and strong compared with conventional refractories. In addition, their stable mineral composition provides excellent corrosion and wear resistance.

In the refining of smelted metals to higher purity, graphite is used for molten metal stirring rotors. Graphite is also used for continuous casting dies because it has high heat resistance and low wettability with molten metals.\nContinuous casting is widely used not only in the steel industry but also in the production of non-ferrous metals such as copper and aluminium. The manufactured products are used in various fields including automotive, shipbuilding, and construction.\n <\/p>\n <\/div>\n<\/section>\n\n\n\n

Excellent Heat Resistance<\/h3>\n <\/div>\n

Our Graphite can be used up to approximately 3,000\u2103 in inert atmospheres and up to about 400\u2103 in oxidizing atmospheres. One of special characteristics of graphite is that mechanical strength increases as the temperature gets higher up until 2,500\u2103 in inert atmospheres.<\/p>\n\n
