FAQ
Why do the normal eletrodes existe broken situation?
There are several reasons, but two are more important:
a. The power is too high, and the electrode can't suport it;
b. The connection between two parts is not good.
- Q:The difference between graphite electrode and graphite rod
- Graphite rod for non metal products, as carbon arc gouging cutting process in an essential pre welding cutting supplies, is composed of carbon and graphite with appropriate adhesive, through the extrusion, the temperature of 2200 DEG C after baking rotary plating a layer made from copper, high temperature resistance, good electrical conductivity, is not easy fracture, suitable for metal cutting into required shape.
- Q:The reason why graphite is used as electrode
- Graphite has good thermal stabilityThe softening point of copper in 1000 degrees, easily deformed by heat, the melting point of graphite is 3850 + 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade. In comparison, the thermal expansion coefficient of graphite material is only 1/30 of copper material.
- Q:Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?
- Graphite electrode should be relatively pure, composed of graphite.
- Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
- Because will cause a short circuit, the best selection of bag type dust collector, our company is graphite in Linzhou, and before you like, then Xinxiang Keli machinery to help us to design a set of dust removal equipment, and then the operation almost no dust, you can consult the specific
- Q:Why should graphite paper be placed between the heater and the graphite electrode?
- Determine the thickness of the graphite bowl, the thickness of the graphite bowl is generally 3 mm -6 mm, three, determine the diameter of the heater, according to the diameter of the crucible and the thickness of the graphite bowl, calculate the inner diameter of the heater. The gap in the quartz crucible diameter phi = +2 times is +2 times the wall thickness of stone bowl bowl and graphite heater if the graphite bowl wall thickness is a, graphite bowl gap and heater for B (b=5 mm), phi = Phi Phi +2a+2b= within the outer crucible outer crucible +2 (a+b) four, to determine the effective heater the height after practice, the effective length of the quartz crucible heater is high 1.6 to 1.8 times.
- Q:How do graphitized electrodes differentiate between high power and low power?
- In an electrolytic cell, the current from a class called graphite anode plate into the electrolyte electrolysis industry, the anode is made of plate shape, so called graphite anode plate, widely used in electroplating, wastewater treatment, industrial anti-corrosion equipment or special materials.
- Q:Why should the carbon brush for the trolley be made of graphite?
- What you said is the graphite electrode graphite, there may be a high pure graphite graphite conductive rate so high, strong, high density, the graphite is mostly used in motor vehicles, such as generators, and electric tools.
- Q:How about graphite electrode high-temperature oxidation resistant coating?
- The utilization ratio of graphite energy can reach more than 95%. Many kinds of antioxidant paint, it is recommended to directly find their technicians, you can give professional advice, according to the actual situation, the reasonable use of high-temperature oxidation resistant paint.
- Q:Can graphite be used as an electrode for electrolysis of silver in silver nitrate?
- Xiaoyi Liyang said the principle is correct, but can get silver? I think we can solve the problem if we take proper measures to get the silver elements, such as separating the anode and the cathode from the salt water!
- Q:Graphitized coke, graphite, broken, mixed up, how to export?
- Graphite fossil oil coke is the best smelting carburizing agent. In the steel-making industry, to produce good steel, there must be good raw materials, including good carburizing agent, and the graphitization of petroleum coke is the best carburizing agent.
