Product Description:

Specifications:

The chemical composition is pure: high carbon, low sulfur, tiny nitrogen, slightly less harmful impurity.

The carburant has excellent features of high carbon, low sulfur, low nitrogen and little impurity. This product is used in casting, can significantly increase the amount of scrap steel, reduce the pig iron dosage or do not use pig iron. At present most recarburizer are suitable for electric furnace smelting, also have a few special recarburizer with fast absorption rate is used in cupola furnace.

Q:How to identify a laptop shell is carbon fiber
Carbon fiber, as its name suggests, is made from carbon fiber, so there are several characteristics. First, if it is not colored, you can see the obvious fiber. Second is black carbon color. And it's a lot more than ABS.
Q:Iron and steel are different in terms of carbon content
. An iron carbon alloy with a carbon content of less than 2% is a steel, and a carbon content of more than 2% is called iron. Steel is widely used because of its toughness, elasticity and rigidity. Life is exposed to steel, but people call different. For stainless steel, whether or not the magnet is sucked on or not, as long as the quality standards are met, it is stainless steel. Therefore, from the perspective of metallurgy said, no rust said. The main element of stainless steel corrosion resistance is chromium. If the content of chromium is above 10.5%, the steel will not rust. When smelting, the alloy elements added are different, so there is a difference between the magnet and the suction.
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 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 is the difference between gold resistance and carbon resistance?
Metal film resistance, high precision, overload capacity, high temperature coefficient, but the price is also higher. Commonly used in some demanding or more accurate circuit, such as instrumentation, precision power supply. Carbon film resistors have high cost performance and low cost, but they have larger errors. A large number of applications in civil electrical products. Such as television, air conditioning, stereo and so on.
Q:How do carbon and oxygen double bonds?
Such as esterification can be generated, as well as aldehydes oxidized into ketones, can produce carbonyl
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: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 are the basic structures of iron carbon alloys?
The symbol is A. The stable austenite has a temperature of 727 DEG C, when the solubility of carbon is 0.77%, the strength, hardness and plasticity of austenite are very good, which is the organization required for high temperature forging or rolling of most steels.Cementite: a metallic compound of iron and carbon with a carbon content of 6.69%. The formula Fe3C is expressed in symbolic Cm. High hardness, poor plasticity, hard and brittle, the number of cementite increases, strength and hardness increase, while plasticity decreases.
Q:Carbon Roast Lamb Leg practice formula
Step 1: the leg with a knife cut, and then put into the seasoning pickled, according to the guests taste add salt, pepper, fennel, pepper and so on, this time can not add cumin. These ingredients should be fully blended and then applied to the surface of the meat. Then sealed with a sealed instrument to allow the meat to be fully salted and flavored, preferably 3 hours.
