What kinds of carburizers can be applied in the foundry industry?
High quality castings: high quality carburizers, such as graphitization carburizers and graphite electrode carburizers, are used to produce ductile iron castings.
nickel smelting
Difference between regenerated electrode and graphite electrode
Regenerated electrode, also known as regenerated graphite carbon rod. The regenerated graphite electrode can be produced by using the processing and cutting debris or waste products of graphite materials as raw materials
Introduction and application of earthy graphite
arthy graphite is also called amorphous graphite, cryptocrystalline graphite or microcrystalline graphite. The crystal diameter of this kind of graphite is generally less than 1 micron
Flue gas desulfurization technology of petroleum coke calcination 2
The principle of ammonia desulfurization is to use ammonia gas to react with sulfur dioxide in petroleum coke to form ammonium sulfate.
Flue gas desulfurization technology of petroleum coke calcination 1
The desulfurization effect is obvious, but the reaction period is long, so it is more suitable for small and medium-sized desulfurization plants.
Identification method of microcrystalline graphite and anthracite
Although the main components of natural microcrystalline graphite and anthracite are carbon elements, there are great differences in crystal structure and physicochemical properties. It can be comprehensively identified by sensory method
What are the reasons for electrode paste leakage
Electrode leakage paste refers to the molten liquid electrode paste in the electrode flowing out from the damaged electrode barrel
Determination of specific resistance of electrode paste during baking
Place the corundum crucible containing the electrode paste sample in the silicon carbide rod electric furnace
Sintering heat source of electrode paste in electrode shell
heat conduction of the electrode itself. The temperature of the electrode tip can reach about 3500 ℃ due to the arc generated, and the heat is conducted from the bottom to the top
Volatile range of electrode paste
The lower the ash content in the electrode paste, the better, but limited to the source of raw materials, it is generally not higher than 5%. If the ash content is too high
