Graphite Die for Horizontal Continuous Casting Machine H001

Description:
Graphite components are critical to the process and allow the metal processing to be monitored continuously from the liquid state to the solid state, while forming semi-finished products (wires, bars, tubes, strips, etc. )
The graphite "die" used in this transformation, permits: The shaping of the metal, the heat extraction necessary to transform the metal from liquid to solid state

The technical index:
Content: 99.7%
Ash: ≤ 0.3
Bulk Density(g/cm³ ): 1.85
Compressive strength: 85 MPA
Short hardness: ≥ 50
And we also can make the abnormity of graphite products, which can use for key; Manifold; Spline, ball valves, and so on.

Graphite: The Material With Exceptional Properties:
Unlike most materials, the tensile, compressive and flexural strengths of graphite increase as temperature rises to 2, 700 K, beyond which they fall again, graphite has about double its room temperature strength. The temperature coefficient of electrical resistivity of graphite is negative, unlike that of metals. Graphite has good electrical Conductivity. Near absolute zero, graphite has only a few free electrons and acts as an insulator. As temperature rises, electrical conductivity increases.

The thermal conductivity of graphite is higher than that of many metals and falls with increasing temperature. The thermal conductivity of graphite varies from one graphite grade to another but also with the degree of graphitization.

The coefficient of thermal expansion is in the order of 3 x 10 -6 K-1 and is, therefore, only about one quarter that of iron. It varies from grade to grade and depends on process conditions and the properties of the starting raw materials. Graphite grades differ only slightly in their specific heat
