Product Description:

1.Structure of Calcined Petroleum Coke Description

Calcined Petroleum Coke is made from raw petroleum coke,which is calcined in furnace at a high temperature(1200-1300℃).CPC/Calcined Petroleum Coke is widely used in steelmaking,castings manufacture and other metallurgical industry as a kind of recarburizer because of its high fixed carbon content,low sulfur content and high absorb rate.Besides,it is also a best kind of raw materials for producing artifical graphite(GPC/Graphitized Petroleum Coke) under the graphitizing temperature(2800℃).

2.Main Features of the Calcined Petroleum Coke

High-purity graphitized petroleum coke is made from high quality petroleum coke under a temperature of 2,500-3,500°C. As a high-purity carbon material, it has characteristics of high fixed carbon content, low sulfur, low ash, low porosity etc.It can be used as carbon raiser (Recarburizer) to produce high quality steel,cast iron and alloy.It can also be used in plastic and rubber as an additive.

Q:What is the carbon content of 45# steel?
The main component of 45# steel is Fe (Tie Yuansu), and contains the following elements:C:0.42~0.50%Si:0.17~0.37%Mn:0.50~0.80%P: = 0.035%S: = 0.035%Cr: = 0.25%Ni: = 0.25%Cu: = 0.25%Density 7.85g/cm3, elastic modulus 210GPa, Poisson's ratio 0.269.
Q:What is the thickness of carbon fiber heating?
The hair line is 4-5mm, and here is the 2CM thermal insulation board. It's only 2.4,2.5 of the total. You can go to Ji'nan emperor long carbon fiber to see, they have a full product and reliable quality.Please accept the answer and support me.
Q:What is the difference between carbon fiber and carbon crystal? Five
South Korea has a long history of electric heating, there is no domestic manufacturers have such technology! "Carbon crystal" is in the past two years, the domestic suddenly came out, it is estimated that dozens of homes!
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:How many points can Yongan change for 1 carbon coins?
Yongan APP one hundred carbon points, change a carbon coin
Q:What is sintered carbon?
Sintered carbon is generally used as a filter element, and also of good quality, but very few, most of which are of poor quality.Sintering is the process in which powder or powder compacts are heated to a temperature below the melting point of the basic component and then cooled to room temperature at a certain rate and speed. The result of sintering is bonding between the powder particles, increasing the strength of the sintered body, and changing the aggregate of the powder particles into agglomerates of grain to obtain the desired physical or mechanical properties of the product or material.The sintering process refers to the processing program and the sintering process system selected according to the characteristics of the feedstock. It has a direct and important influence on the production and quality of sinter production.
Q:What are the 3K, 12K, UD, etc. in the appearance requirements of the carbon fiber bicycle? What's the difference?
3K has 220 grams and 240 grams a square meter, we do carbon fiber automotive supplies, that is, the higher the number of 3K K, the width of each bundle of carbon fiber filaments, each bundle has hundreds of silk composition
Q:What is the effect of carbon equivalent on welding?
The greater the carbon equivalent, the greater the tendency to harden the welding material, and the cold crack is likely to occur in the welding area.Carbon equivalent is related to hardening and cold crack tendency due to welding heat:When the carbon equivalent is large, the martensite structure which is easy to harden in the welding heat affected zone is sensitive to crack and hydrogen quenching. Hardening causes more lattice defects. In the condition of stress and thermal imbalance in the weld, the lattice defect is called the crack source, which increases the tendency of cold crack in the weld.
Q:60T carbon fiber is equivalent to T hundreds of carbon fibers
One, 60T carbon fiber and T hundreds of carbon fiber does not have any corresponding, 60T belongs to M series (high modulus carbon fiber). Only 30T corresponds to T800.
Q:Why does the carbon content of steel increase and the mechanical properties change?
Steel is an alloy of iron and carbon in 0.04%-2.3% between carbon content. In order to ensure its toughness and plasticity, the main elements in addition to iron, carbon and carbon content is generally not more than 1.7%. steel, and silicon, manganese, sulfur and phosphorus. Classification method of steel variety, there are seven kinds of main methods:1, according to quality classification(1) ordinary steel (P = 0.045%, S = 0.050%)(2) high quality steel (P, S = 0.035%)(3) high quality steel (P = 0.035%, S = 0.030%)2. Classification by purpose(1) building and engineering steel: A. ordinary carbon structural steel; B. low-alloy structural steel; C. reinforced steel(2) structural steelSteel manufacturing machinery: A. (a) quenched and tempered steel; surface hardening (b) steel structure: including carburizing steel, surface hardened steel, with infiltration of ammonia (c) free cutting steel; steel structure; (d) cold forming steel: steel, cold stamping.B. spring steelC. bearing steel(3) tool steel: A. carbon tool steel; B. alloy tool steel; C. high speed tool steel(4) special performance steel: A. stainless acid resistant steel, B. heat-resistant steel, including oxidation resistant steel, hot strong steel, air valve steel, C. electric heating alloy steel, D. wear-resistant steel, e. low temperature steel, F. electrical steel(5) professional steel - such as bridge steel, shipbuilding steel, boiler steel, steel for pressure vessel, steel for agricultural machinery, etc.
