Good Quality Low Ash Carbon Electrode Paste -Ash4


Electrode paste is used in closed electric smelting furnace as continuous self-baking electrode to produce calcium carbide, ferroalloy and so on. During the furnace operation, electrode paste acts as current conductor.

Product Description

Carbon Electrode Paste is a self-baking electrode used in submerged arc furnaces for delivering power to the charge mix. Electrode Paste is added to the top of the electrode column in either cylindrical or briquette form. As the paste moves down the electrode column the temperature increase causes the paste to melt and subsequently bake forming a block of electrically conductive carbon. Electrode Paste is essentially a mix of Electrically Calcined Anthracite (ECA) or Calcined Petroleum Coke (CPC) with Coal Tar Pitch.


1. Lower ash content;

2. Acurate dosing and stable volatile content;
3. Good electric and thermal conductivity and the sintering speed apropriate to that of consumption of working end;
4. Smelting at lower temperature with certain fluidity and homogeneous composition;
5. High resistance to high temperature, oxidation and thermal shock, low resistivity and high mechanical strength after sintering.

Q:What should we do to reduce carbon emissions in our lives?
The use of public transport, of course, is best to walk long distances, as far as possible the use of roads or railways, aircraft carbon emissions, the largest use of disinfection chopsticks, do not use disposable tableware, handkerchiefs do not use napkins
Q:What is carbon steel, carbon manganese steel?
Compared with other kinds of steel, carbon steel is the earliest, low cost, wide performance range and the largest amount. For nominal pressure PN is less than or equal to 32.0MPa, temperature of -30-425 water, steam, air, hydrogen, ammonia, nitrogen and petroleum products such as medium. Commonly used grades are WC1, WCB, ZG25 and high quality steel 20, 25, 30 and low-alloy structural steel 16Mn
Q:What type of carbon copy sheet can be printed on? How many copies?
Generally 100 pages, such as:One copy of the two couplet is 50 copies.One copy of the triad is 33 copies.One copy of the quadruple is 25 copies.This is a five of the 20.
Q:Why carbon 14 can be used to measure the age of matter?
Then, after the death of the animal's plant, because carbon 14 is a radioactive isotope, still continue to decay, death of plants and thus reduce carbon 14 content in a day. 14 the amount of carbon can be determined by measuring the radioactivity. The half-life of carbon 14 for 5730 years, after 5730 years, the amount of carbon 14 only half. Radiocarbon method is the most commonly used method of archaeology, it can be concluded that the year for up to 50000 years.
Q:What is the composition of carbon in stainless steel?
The quality and performance of steel are determined according to needs, and different elements should be included in different requirements(1) carbon, the higher the carbon content, the higher the hardness, but its plasticity and toughness are worse(2) sulfur is the harmful impurity in steel. The steel with high sulfur content is easy to crack when it is processed by high temperature. It is usually called hot brittleness(3) p; can make the plasticity and toughness of the steel decreased significantly, especially at low temperature is more serious, this phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus must be strictly controlled. But on the other hand, sulfur and phosphorus containing high in low carbon steels, can make the cutting easily broken, is benefit to improve the machinability of the steel is.(4) manganese; can improve the strength of steel, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel, manganese content of high alloy steel (Gao Menggang) has good abrasion resistance and other physical properties.(5) silicon; it can improve the hardness of steel; but the plasticity and toughness decrease; the steel used in the electrician contains a certain amount of silicon, which can improve the soft magnetic properties(6) tungsten can improve the red hardness and heat strength of steel, and can improve the wear resistance of steel
Q:What is carbon coffee fiber?
The carbon coffee fiber uses the coffee residue left after the coffee and is made into crystal by calcining, then ground into nanometer powder and added to the polyester fiber to produce a functional polyester staple, a coffee carbon fiber. Its main functions are bacteriostasis, deodorization, divergence of negative ions and anti ultraviolet rays.
Q:About baking raw carbon problems
This is simple, you get a newspaper ignition, and then find some sticks to make a fire, put some charcoal to burn it, take a fan to fan it, drop a few drops of oil go up, it will burn more prosperous Oh!
Q:How about carbon content of coal ash?
3, burning(1) prepared burning specimen with constant weight in the outer side of the crucible crucible, only a few 10-18ml and drying on the only black ink written into the code, mother Eph furnace, baby 50+-25 degrees Celsius temperature burning 1 hours after cooling, weighing with analytical balance, write down the number of crucible weight again after burning, and then weighed to weight two times constant (weight <=0.0004 grams). Record crucible weight G1.(2) place about 1 grams of dry ash sample in a constant crucible, and accurately weigh (accurate to 0.0001 grams), record (crucible + sample) weight G2. (3) a crucible with soil sample is placed in a crucible cover, heated to 875 degrees Celsius in the Maffei furnace for ignition, keep the temperature of 850+-25 degrees Celsius, after 2 hours, take out, after cooling, cooling to room temperature to put in a drying box. 4 W T'o X7 I3 L) |% "Z (4) weighing burned (crucible + specimen), down under the weight of G3.4. Calculate ash carbon content C (%) = (G2-G3) / (G2-G1) *100 (%)
Q:How about Zonta carbon technology
The factory garbage to death, wages do not rise, but down, quarterly awards fell by more than half, production targets set very high, employees can not reach the goal, not to work overtime. This is a company's way of restricting employees to work overtime. And so on, the target production has been added, so never meet the requirements, overtime do not think. A large piece of employee turnover now
Q:What's the difference between coal and carbon?
Coal has a certain luster, which contains a certain mineral oil, etc., is a relatively tight crystal structure. After baking coal coke, coal tar removal became less organized a lot of voids in carbon, most of which are carbon elements. Carbon produced by coal; also called coke. In addition, wood charcoal is also called charcoal.Coal and carbon can all be used as fuel. Most coal burns with smoke and may smell. Carbon burning generally does not have too much smoke, but also less odor.Carbon gap structure makes carbon have good adsorption, so carbon is often used as adsorbent material, used for adsorption of water, odor and so on.
