Resin graphite tube heat exchanger is now more and more used in chemical and steel industries,It’s unique properties make it unique and irreplaceable. The failure forms of the heat exchanger has two kinds: graphite tube breaking, graphite tube blasting. Graphite is a brittle material, when the flange is be connected, it can not be unrestricted use of torque, so the corresponding different graphite materials to use the correct torque, so that the device can be guaranteed. Often a lot of times when the torque is not correct will cause the leakage of equipment and the destruction of graphite materials. The key components of graphite heat exchanger are composed of corrosion resistant graphite. After asphalt mixing, extrusion (or vibration forming), the…
Because of its characteristics of light weight, high resistance to high current and low electrode wear, it is very suitable for the manufacture of precision molds in the automotive industry, and the electrode graphite is one of the development trends of the discharge machining technology. Graphite electrode has the advantages of easy processing, high metal removal rate, small graphite loss, therefore, more and more die plant to abandon the copper electrode and switch to graphite electrode. Also some of the shapes of the electrode made of copper, but graphite is easy molding and copper electrode is heavy, not suitable for processing large electrodes, these factors have accelerated the graphite electrode in the mold manufacturing industry is more and more extensive…
The graphite crucible has good thermal conductivity and high temperature resistance, high temperature in use process, small thermal expansion coefficient. It has a certain anti strain properties. The acid alkali solution, corrosion resistance strong, excellent chemical stability. The graphite crucible, because has more excellent performance, so in casting, metallurgy, machinery, chemical and other industrial sectors, is widely used for smelting alloy tool steel and non-ferrous metal and alloy smelting. And have a good technical and economic effect. The main raw material of graphite crucible is the crystallization of natural graphite, keep the physical and chemical properties of various original natural graphite. Graphite for acid and alkaline solution of stronger corrosion resistance, excellent chemical stability. There are two kinds of domestic…
