The scope of application of graphite cold iron blocks

As a conductive substance, graphite cold iron block is used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, rectifier cathodes, graphite gaskets, telephone components, TV picture tube coatings, etc.

Graphite cold iron block as wear-resistant lubrication material: rigid industry often uses graphite as a lubricant, can not use lubricating oil at high speed, high temperature, high pressure, but graphite wear-resistant materials in 200~2000 high folding speed can be used without lubricating oil.

Many configurations that convey spoilage media accept graphite materials to make piston cups, seals and bearings and operate without lubricating oil. Graphite emulsions are also good lubricants for many metal processing (wire drawing and extubation).

Graphite cold iron blocks have good chemical stability. Because graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability, graphite after special treatment is mostly used to manufacture heat exchangers, which are composed of echo tanks, condensers, combustion towers, exhaust fans, coolers, heaters, filters and pumps. Widely used in kerosene chemical industry, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.

Graphite cold iron blocks can be used as materials for casting, sanding, stamping and high-temperature metallurgy. Because graphite has a small coefficient of thermal expansion and can withstand sudden changes in cooling and heating, it can be used as a casting mold for glassware. After obtaining ferrous metal with graphite, the casting size is accurate, the appearance is beautiful, the yield is high, and it can be used without processing or only a small amount of processing, saving a lot of metal.

In powder metallurgy technology, such as cemented carbide production, graphite materials are commonly used to make molds and porcelain boats for sintering. Sensory crystal growth crucibles, area refining vessels, support fixtures, heaters, etc. All of monocrystalline silicon is made of high-purity graphite, and other graphite can also be used for vacuum-smelted graphite heat insulation plates and bases, tubes, rods, plates, grids and other components of high-temperature resistance furnaces.

　　Graphite cold iron manufacturer: Graphite electrode transportation precautions

In recent years, carbon graphite electrodes have been increasingly used in mining systems, diesel systems, railway systems and high-tech industries. One of the carbon graphite electrodes is a conductor that releases electrical energy in the form of an electric arc to heat and melt the charge. Let's talk about the precautions in the transportation of carbon graphite electrodes.

First of all, vehicles transporting carbon-graphite electrodes over long distances must be covered with rainproof tarpaulins to prevent carbon-graphite electrodes from moisture.

Secondly, when lifting or transporting the carbon graphite electrode, pay attention to prevent the carbon graphite electrode from tilting or sliding and causing damage.

Moreover, in order to protect the end and screw of the carbon graphite electrode, the carbon graphite electrode cannot be hung directly with a hook. Finally, when disassembling the joint box, care must be taken to avoid joint collision, resulting in thread fracture and shortening the life of the carbon graphite electrode.
