Carbon raiser is a type of material that is added to molten steel to increase its carbon content. It is also known as carbon additive or recarburizer. It is used in iron and steelmaking and casting. It has good characteristics of anti-oxidation, high density and low resistivity.
It is made from high quality petroleum coke which is calcined in DC electric calciner to remove the moisture and volatile matter. The final product has the characteristics of low sulfur and ash content.
The global market for calcined petroleum coke is growing due to growth in the steel industry and rising iron & aluminum smelting production. In addition, increased demand for carbon anodes in the aluminum sector is expected to drive the market. However, volatile crude oil prices and refining economics are major challenges for the calcination industry.
The calcining process transforms the raw petroleum coke into a solid form that can be stored and handled in a safe way. It can be used as a fuel in refinery boilers to produce steam and electricity. This reduces energy costs, and can be a viable alternative to coal.
The calcined coke has a lower coefficient of thermal expansion, so it can be safely transported and stored in high-temperature environments. It is also a low-ash, low-sulfur material that does not generate significant amounts of toxic fumes. It is also available in a variety of sizes and forms, and can be used for many different applications.
Calcined anthracite is a highly refined form of coal that can be used as a carbon raiser for the production of graphite electrodes and ramming paste. It has low ash, low resistivity, and low sulphur content, which makes it an ideal choice for carbon electrode paste and cathode blocks.
The global calcined anthracite market is expected to grow rapidly in the near future due to rising demand from the steel manufacturing industries. However, fluctuating raw material prices and availability of substitutes are likely to hinder the growth of the market in the long run.
The calcined anthracite carbon raiser market can be segmented on the basis of application and geography. The global market is dominated by the iron and steel industry, which accounts for more than half of the total revenue. The other key end-use industries include aluminum, pulp and paper, and power generation. The calcined anthracite can be produced by gas calcination or electrically calcined anthracite (ECA). Some of the major players in the calcined anthracite marketplace are Shanxi Hongqiqu New Material Co Ltd, RHEINFELDEN CARBON GMBH, Ningxia Hengtai Carbons Co Ltd, Zhengzhou Xinhua Raw Materials Technology Co Ltd, Evergreen Industry Co Ltd, Guizhou Dazhong No.7 Grinding Wheel Co Ltd, and Gansu Yuanda New Resources Co. Ltd.
Graphitized petroleum coke is a carbon product that is used for metallurgical applications. It is manufactured through destructive distillation of various blends of bituminous coal in a kiln. It has a high fixed carbon content and is available in a variety of sizes, from 30-micron powders to 20-centimeter lumps. It can be used for a variety of carbon products, including sealing and lubricating materials, electricity brushes, compound brakes, and more.
The combustion of petroleum coke was investigated using a porous media thermo-effect cell (PMTEC). Different catalysts were tested, and the kinetic data were analyzed with Kissinger-Akahira-Sunose and Ozawa-Flynn-Wall methods.
Graphitized petroleum coke is widely used in metallurgy and foundry as a recarburizer to improve the carbon content of steel-melting and casting. It can lower the smelting cost and use less scrap iron than ordinary coke. It has low ash and sulfur content, low volatiles, and a high carbon recovery. It is also environmentally friendly and has low nitrogen and oxygen levels.
A carbon raiser is a type of material used to increase the carbon content in iron or steel. It is also used to improve the hardness and strength of the metal. It can be made from calcined petroleum coke, graphitized petroleum coke (GPC), anthracite coal or other materials. It is a crucial component in the iron and steel industry, and can be used in various applications, such as casting, forging and steelmaking.
It is important to select the right charge carbon for a particular application. A high-quality charge carbon has low levels of nitrogen, oxygen and hydrogen. This can reduce scrap rates, as well as lower the amount of unwanted compounds in the final product.
Several graphite samples with different microstructures were prepared from anthracite coal using industrial silicon powders as catalysts. X-ray diffraction and temperature programmed oxidation were used to assess the structural evolution of these materials with treatment temperature. The results show that the microstructure of a coal-based graphite depends on both the initial anthracite size and the presence of mineral matter.
