Product Name 　　　　 Carburant 　　 Product Characteristics 　　　　 High content of fixed carbon, low sulfur content, stable carburetion effect and high absorptivity of carbon. 　　 Scope of Application 　　　　Applied to the carburetion of various electro-smelting cast steel and cast iron. 　 Granularity 　　　　 common granularity: 0-10mm, or supplied upon users’ special requirement 　 Method of Application 　　　　1) Adjusting carbon content while blending, and adding it to the place below the middle part of the electric furnace along with metal furnace charge when melting down liquid steel (iron) in accordance with the requirement of carbon content; absorptivity of carbon could reach 90%-95%; during strong carburant melting, residue shall not appear, otherwise, it is easy to be wrapped in the non-waste residue and influence the absorption of carbon thereby; 　　　　2) after the liquid steel (iron) melting, adjusting carbon content, which may be added on the surface of liquid steel (iron); while melting down through electric furnace, atirring stirring or manual stirring of liquid steel (iron) makes the carbon dissolved and absorbed, and the absorptivity of carbon is approximately 85%. Specification and Indicators are as follows:： 　 　　　　 Category Grade Chemical Indicators Fixed Carbon（%） Total Sulfur（%） Ash Content（%） Ash Content（%） Volatile Content（%） Water Content（%） Carburant Extra Grade ≤3.6 ≤0.9 ≤0.2 ≥95 ≤0.2 Grade I ≤5.0 ≤1.2 ≤0.6 ≥93 ≤0.3 Grade II ≤6.0 ≤1.2 ≤0.6 ≥92 ≤0.3 Grade III ≤7.0 ≤1.5 ≤0.6 ≥90 ≤0.3 Carburant Extra Grade ≤3.5 ≤0.5 ≤0.3 ≥96 ≤0.1 (Electric Calcined) Grade I ≤3.5 ≤0.6 ≤0.6 ≥95 ≤0.15 Grade II ≤4.0 ≤1.0 ≤1.0 ≥94/93 ≤0.2 Grade III ≤7.0 ≤1.0 ≤1.0 ≥90/1/2 ≤0.3 II. Recarburizer for Forged Steel: Selection of high-quality Taixi smoke-free washery coal is made to calcine in calciner under 800—1200℃. It is an ideal raw material for steel making.
