Product Description:

Recarburizer Application:


- Lower the impurities in the cast iron, 

- Choose the right recarburizer can lower the casting cost. 

- Recarburizer is essential auxiliary additives for production of high quality steel .

- Also it can can be used as additive for produce other product like brake pad used as friction materials; 

- High quality recarburizer is after graphitizing process,under high temperature,the arrangement of carbon atoms in microstructure of graphite.

so call it graphitization ,graphitizing can lower the impurities in recarburizer, increase the carbon content, lower the sulfer content. 

 

Product categories:

 

At present China have 3 Type Recarburizer:

- Graphite powder ,the dust power of graphite electrode

- Calcined Petroleum Coke part of domestic steel factory use it as recarburizer.

- Graphitized Petroleum Coke ,as recarburizer used for steel casting

Q:I bought a grill myself and went to barbecue with my friends the day after tomorrow, but I can't ignite the carbon. What should I do?
Is it barbecue in the field? If so, there are many ways to ignite carbon in the wild.The simplest, affordable way is to pile up the fire, and then use the charcoal on it, charcoal will be used after burning.At home, it is placed directly on the gas range, ignited.Charcoal direct ignition is not convenient, it is best to use other things as medium ignition.Be careful when you're in the barbecue. Watch out for the fire.
Q:What does carbon burning mean?
Put the burning carbon under the iron plate and make a copy of it on the iron plate, that is, carbon burning!
Q:Material characteristics of carbon fiber
Carbon fiber is a kind of new material with excellent mechanical properties due to its two characteristics: carbon material, high tensile strength and soft fiber workability. The tensile strength of carbon fiber is about 2 to 7GPa, and the tensile modulus is about 200 to 700GPa. The density is about 1.5 to 2 grams per cubic centimeter, which is mainly determined by the temperature of the carbonization process except for the structure of the precursor. Generally treated by high temperature 3000 degrees graphitization, the density can reach 2 grams per cubic mile. Coupled with its weight is very light, it is lighter than aluminum, less than 1/4 of steel, than the strength of iron is 20 times. The coefficient of thermal expansion of carbon fiber is different from that of other fibers, and it has anisotropic characteristics. The specific heat capacity of carbon fiber is generally 7.12. The thermal conductivity decreases with increasing temperature and is negative (0.72 to 0.90) parallel to the fiber direction, while the direction perpendicular to the fiber is positive (32 to 22). The specific resistance of carbon fibers is related to the type of fiber. At 25 degrees centigrade, the high modulus is 775, and the high strength carbon fiber is 1500 per centimeter.
Q:Is the hardness or softness of the steel with higher carbon content?
Carbon is the major element in determining the properties of steel, because changes in carbon content lead directly to changes in crystal structure.
Q:What are the carbon monoxide collection methods?
It can only be collected by drainage. Carbon monoxide is not soluble in water. Because carbon monoxide is poisonous and the density is very close to the air, it can not be collected by exhaust air
Q:Why use carbon batteries for alarm clocks?
You said carbon battery is called alkaline battery his standard voltage is 1.5V the charging the battery is generally 1.2V. to this problem is not a reward.
Q:The importance of carbon in life
The carbon containing compounds exist in hundreds of thousands, divided into inorganic and organic compounds in two categories, known as carbon containing inorganic substances in daily life and industrial and agricultural production is the raw material of carbon calcium carbonate as food additive sodium, sodium bicarbonate, calcium carbonate and lime material acetylene gas (acetylene), chemical fertilizer ammonium bicarbonate, chemical gases such as carbon dioxide.
Q:What do you mean by carbon fiber for 1K, 3K, 6K and 12K?
Upstairs copy so much, people watching tired not tired.1K, 3K, 6K, 12K refers to the carbon fiber yarn containing the number of filaments, K is unit (thousand), 1K is 1000 followed, 3K is 3000, and so on, and so on!
Q:What's the difference between lead and carbon?
The difference is that one of the similarities is that the appearance is black. However, the lead section is metallic luster. Carbon density is very small, about 2G per cubic centimeter, lead density is great, the density is more than 10g per cubic centimeter. Carbon is a nonmetal that can be converted into diamond. Lead is a kind of metal. Carbon is a chemically stable substance at normal temperature. Without poison, activated carbon can be used as a gas mask. Lead is a heavy metal that is harmful to humans. The chemical properties are more lively and can be used as lead batteries. The melting point of lead is very low, only a few Baidu, and the melting point of carbon can reach more than 3000 degrees. Edison made the filament out of carbon. You know that?.
Q:What is the burning point of carbon?
Generally speaking, the ignition point of charcoal is relatively low, about 300 degrees, and the coal is higher, at 600 - 700 degrees!
