After years of research and development. Qingdao Duratight focus to supply customers carbon additive/Graphite Petroleum Coke(GPC) with high carbon, low sulfur, low nitrogen, less harmful impurities and other excellent characteristics, the product is a new type of material for improving the process and quality of Molten Iron and steel in smelting industry. It has become an optimum carbon additive in smelting production of major smelters in recent years. Duratight Brand GPC can promote the graphite nucleation ability in molten iron, increase the quantity of nodular graphite cast iron, improve the structure of gray iron, and raise the grade of cast iron.
In 2003, the company developed a new process to overcome the shortage of raw material supply, reaching a monthly supply of 4500 tons, as a result of sufficient volume, supply stability, as many trading companies and steel plant designated suppliers.
DOMESTIC CUSTOMER SCALE: 11 Steel Plant users, 68 foundries, 47 brake plants.
FOREIGN CUSTOMER SCALE: Foreign Sales performance is good, customers in Japan, South Korea, India, the United States, Thailand, Vietnam, Malaysia, Russia, Ukraine, France and 22 other countries, and the use of manufacturers continue to increase, applications continue to expand.
Specific indicators are as follows:
Fixed Carbon (minimum)
Ash Content (highest)
Volatile matter (maximum)
Particle size (90%)
Nitrogen content (maximum)
By using the Duratight Brand Carbon Additive,the amount of scrap steel can be increased greatly, and the amount of pig iron can be reduced or no pig iron can be used. The carburant is characterized by good absorption of carbon in molten iron and no return of slag. The production cost of castings can be greatly reduced by using the carburant.
1. USAGE: used for special steel making and ductile iron casting.
2. Product features: High fixed carbon content, low sulfur content, stable carburizing effect, high carbon absorption rate.
3. SCOPE OF APPLICATION: It is used for carbonizing cast steel and cast iron in various electric furnaces.
4. GRANULARITY: Commonly used granularity: 0.2-1mm 1-5mm, 1-3mm, 3-5mm, 3-8mm, 5-10mm or according to the special requirements of users.
5. How to use:
1) .The use of more than 5 tons of electric furnace, a single stable raw material, we recommend the method of decentralized addition. According to the requirement of carbon content, the carbon additive and the metal charge are added into the middle and lower part of the electric furnace together with each batch. Carbon Additive in the melting do not slag, or easy to wrap in waste slag, affect carbon absorption. 2) . Using about 3 tons medium frequency induction furnace, the raw material is single and stable, we recommend the method of centralized adding. When a small amount of molten iron is melted or left in the furnace, the carbon additive should be added to the surface of the molten iron once, and the metal charge should be added immediately, and the carbon additive should be pressed into the molten iron to make the carburizing agent in full contact with the molten iron. 3) . Using small medium frequency electric furnace, raw material clip has pig iron and other high carbon material, we recommend carbon additive fine adjustment. After Molten steel/molten iron, the carbon content can be adjusted and added to the surface of the steel/molten iron. The product can be dissolved and absorbed by Eddy current or manual stirring of the steel/molten iron during melting in an electric furnace.
6. Compared with the traditional pig iron:
1) this product is non-metal, melting point is about 1200-1300 degrees, no residue in use, high utilization. 2) the product is easy to produce and use, the consumption is much lower than pig iron, and the production cost of the enterprise is saved. 3) the phosphorus and sulfur content of this product is much lower than pig iron, and its performance is stable.
