Product Description

For more information, please visit our website.

Calcined anthracite carburetant has follwing advantages:
(1). High carbon : High purity 98.5-99.5%
(2). Low sulphur : 0.01% ~ 0.05%. Low sulphur and stable distribution can effectively reduce the adverse effect of sulphur in spheroidizing and pregnant process to the alloy, and it saves the cost.
(3). Low nitrogen : nitrogen content 50 PPM ~ 300 PPM(0.005%-0.03%)
(4). High carbon recovery: 92- 98%.
(5). Fast absorption speed: it's easily dissolve in the molten iron.
(6). High graphite crystal nucleus and high graphitization degree: it can reduce the iron liquid contraction tendency and improve the mechanical properties of casting.
(7). It may increase the dosage of scrap steel and reduce the demand of pig-iron or even without adding pig iron. It may well effectively avoid the heredity of pig iron to affect the casting.
(8). Cost-effective: reduce GPC, power and Inoculant consumption, which will save production cost
(9). Stable carburetion, good absorption rate and distinct temperature-lifting effect: There is no return slag. It can effectively protect and lengthen the furnace life and reduce the consumption of the furnace lining.

What is a Carbon Raiser?

Carbon raiser is an efficient carbon additive material widely used in steel and casting, improving their hardness, strength, and wear resistance. Carbon raisers appear as black granules with sizes of 0.2–2mm, 1–3mm, and 5–8mm. Their chemical composition mainly consists of fixed carbon (F.C), sulfur (S), and nitrogen (N). The primary raw materials for producing carbon raisers include petroleum coke, anthracite, and graphite powder, which are extensively used to manufacture different types of carbon raisers to meet various application needs. XLS Metals has developed high-efficiency carbon raiser products based on user requirements, featuring high F.C content, high absorption rates, and high purity.

Applications of Carbon Raiser

Steel making: By using carbon raisers during steelmaking, the carbon content in steel can be effectively adjusted, improving the steel’s hardness, toughness, and wear resistance.

Casting: Carbon raisers used in casting have the advantages of low sulfur and low nitrogen. They effectively promote the formation of graphite nuclei, improving the graphite distribution and significantly enhancing the quality and yield of castings.

Metallurgy: Carbon raisers adjust the carbon content in alloys, improving various performance aspects, thereby serving the role of carbon enhancement and replenishment.

Classifications of Carbon Raiser

Based on different raw materials, carbon raisers can be categorized into calcined coal carbon raisers, graphite carbon raisers, and petroleum coke carbon raisers. Depending on production processes, they can also be divided into graphite carbon raisers and calcined coal carbon raisers. Combining production processes and raw materials, the main types include graphitized petroleum coke carbon raisers (GPC), calcined anthracite carbon raisers (CAC), and calcined petroleum coke carbon raisers (CPC).

Carbon Raisers for Different Fields

Carbon Raiser for Steel: To reduce steel production costs, carbon raisers for steel usually focus on calcined coal carbon raisers. By calcining anthracite at °C, impurities are effectively reduced, resulting in high carbon content, low costs, and good carbon raising effects. Calcined coal carbon raisers are widely used in various steel production processes, enhancing strength, improving plasticity, and increasing weldability.

Carbon Raiser for Casting: Since sulfur (S), phosphorus §, and nitrogen (N) severely affect casting quality, carbon raisers for casting are often required to have low sulfur, low nitrogen, and low phosphorus characteristics. Graphitized petroleum coke carbon raisers and graphitized carbon raisers are the primary types used in casting, featuring high thermal insulation, high purity, and low harmful elements, widely applied in the production of ductile iron and gray cast iron. They effectively reduce the tendency for white iron defects and enhance the fluidity of molten iron during the casting process, preventing nozzle blockage and improving the plasticity and wear resistance of castings.

Sustainability

As market demands for steel performance diversify, carbon raisers are widely used in the smelting processes of different steel grades and cast iron, effectively improving the mechanical properties of steel and cast iron. With the increasing environmental protection requirements in various countries, carbon raisers have prompted companies to seek greener production methods, becoming a promising eco-friendly furnace material.
