Product Description:

Specification of Calcined Petroleum Coke:

Calcined Petroleum Coke comes from delayed coke which extracted from oil refinery. Although Calcined Petroleum Coke contains a little bit higher level of sulfur and nitrogen than pitch coke, the price advantage still makes it widely used during steel-making and founding as a kind of carbon additive/carburant


petroleum coke price is lower than graphite pet coke. It is widely used by most foundry plants.



Our product has follwing advantages:

The morphology, chemistry and crystallinity of recarburizer have a major impact on the overall casting cost. The combined application and cost benefits, enable foundries to manufacture castings in a highly cost effective manner.



- Recarburiser consumption
- Power consumption
- Inoculant consumption
- MgFeSi consumption
- Furnace refractory wear
- Scrap rate
- Tap to tap time
- Slag inclusions risk
- Chill



- Casting microstructure
- Productivity
- Process consistency


Carbon Recovery:
Compared with calcined petroleum coke, acetylene coke and

graphite electrode scrap, our yields the highest carbon

recovery and fastest dissolution time

Q:Material characteristics of carbon fiber
This allows carbon fibers to have the highest specific strength and specific modulus in all high-performance fibers. Compared with the metal materials such as titanium, steel and aluminium, carbon fiber has the characteristics of high strength, high modulus, low density and low coefficient of linear expansion. It can be called the "king of new materials". In addition to carbon fiber with general characteristics of carbon material, its appearance has obvious anisotropy and soft, can be processed into a variety of fabrics, and the proportion of small, along the fiber axis show a very high strength carbon fiber reinforced epoxy resin composites, the strength and modulus of composite indicator in the existing structural materials is the highest. The tensile strength of carbon fiber resin composite materials are generally in more than 3500 MPa, is 7 to 9 times that of steel, the tensile modulus of 230 to 430G were also higher than that of steel; therefore the specific strength of CFRP material intensity and density can be achieved above 2000 MPa, the specific strength of A3 steel is only 59 MPa.
Q:How do you use carbon fourteen to measure the age?
One is obvious a small amount of sample, only 1 ~ 5 mg samples can be, such as a piece of fabric, bone chips, toner trace of ancient ceramics in the surface or pores can be measured; while the conventional carbon - 14 dating rules 1 to 5 grams of samples differ by 3 orders of magnitude. The two is high sensitivity. The sensitivity of 10-15 to 10-16 isotope ratio measurement; while the conventional carbon - 14 dating rules with a difference of 5 to 7 orders of magnitude. Three is a short measurement time, measurement of modern carbon to reach 1% accuracy, only 10 to 20 minutes; while the conventional carbon - 14 dating is 12 ~ 20 hours. It is due to carbon - 14 accelerator mass spectrometry dating method has the advantage, since its inception, has been paid attention to by archaeologists, paleontologists and geologists, and is widely used. It can be said that within 50000 years of cultural relics on the determination of samples, carbon - 14 accelerator mass spectrometry dating method is determined the accuracy of a maximum of 1. carbon. 14 is a radioactive isotope of carbon, was found in 1940. It is produced by cosmic rays collide with a nitrogen atom in the air, which has a half-life of about 5730 years, as the decay of beta decay, 14 atoms into carbon nitrogen atoms.
Q:What's a carbon cloth to do as a fish pole?
This is difficult, usually with a lathe like tool, by heating in the brush, layer by layer roll up, and finally cut off paint, baking
Q:How to extinguish the charcoal fire?
Charcoal air on the line, but also can use water, but there will be a lot of gases
Q:What's the use of carbon 60?
Used to strengthen metals; used as a new catalyst for storage of gases
Q:What is the cost of carbon emissions?
Q:The outer and inner carbon carbon ribbonA recent study of ribbon,
In fact, to teach you a simple way to distinguish between internal and external carbon, carbon, label paper dip ribbon, with black on the outside of the outer side is carbon, carbon is in inside, no performance difference, now generally used is the most carbon, such as the machine is to use carbon is better, because the wound is not the same, sometimes loose.SATO machine with carbon is better, and the CITIZEN printer inside and outside carbon can be used, in addition to machine limitations, not what the difference is too big, the quality of internal and external carbon ribbon is the same.
Q:What is the effect of carbon equivalent on welding?
The carbon equivalent of less than 0.4%, good weldability; in 0.4~0.6%, poor weldability, welding preheating and other measures to prevent cracks; more than 0.6 words, when welding needs higher temperature and strict technical measures! PS: carbon equivalent =C+Mn/6+ (Ni+Cu) /15+ (Cr+Mo+V) /5, Q235 carbon content in 0.14%~0.22% between, widely used by the company seems to be Q235B, carbon content between 0.12~0.20%
Q:Are carbon fibers flammable?
Carbon fiber has the characteristics of light quality, high strength and not easy to burn. More and more widely used
Q:Is graphite carbon?
They are arranged in eight planes. The net shape is the diamond, which is arranged in a regular hexagon and a layer, and then graphite is formedDiamond and graphite are carbon elements
