Graphite crucible has a very wide range of application in the metallurgical industry. It is used for containing various liquid metal, as a manufacturer of metallurgy, we should know how to use graphite crucible, otherwise there will be some problems in the latter part of the production and application. Here we will introduce the matters which we should pay attention to: 1).Although the quality of graphite crucible is very good, not easy to damage, but we should handle it with care . The impact of falling from high altitude or bumps on the quality is not very big, but it will has crevice and even be broken for a long time so go on. We can’t give any remedy once…
Chopped carbon fiber is made up of carbon fiber filament cut through a short cut, its basic properties are mainly determined by the properties of the carbon fiber filament. Carbon fiber is a kind of fibrous carbon material. It is a kind of strength stronger than steel, density higher than aluminum, corrosion resistance stronger than stainless steel, heat resistant higher than steel, and can be as conductive as copper, with a lot of valuable electrical, thermal and mechanical properties of new materials. Carbon fiber is mainly made of carbon fiber reinforced plastics. Carbon fiber has the flexibility of ordinary textiles, and can be processed into fabric, felt, mat, tape, paper and other materials. Traditional use of carbon fiber in addition…
Carbon / carbon composite material are high temperature friction materials of excellent performance, as the brake materials have been successfully applied in aviation industry. But the friction and wear properties of carbon / carbon composite material strongly depends on the experimental conditions and preparation process. Compared with other friction materials, carbon / carbon composite materials with low density, high temperature resistant, high strength, thermal shock resistance, corrosion resistance, good vibration resistance and suitable friction coefficient and friction performance, is a comprehensive performance excellent high temperature friction material. Carbon / carbon composite material have become the preferred materials for aircraft brake discs. In France, for the civil aviation flying Airbus Company the machine brake system has been completely replaced by carbon…
