Calcium Carbide Smelting Furnace<\/h1>\n
<\/div>\n

High-Yield Calcium Carbide Production by HANI Metallurgy<\/p>\n<\/div>\n

<\/p>\n

\n

The Foundation of the Acetylene Chemical Industry<\/h2>\n

The Calcium Carbide Smelting Furnace<\/strong> is an essential unit for the chemical and metallurgical industries, primarily used to produce calcium carbide (CaC2). As a specialized Calcium Carbide Furnace<\/strong>, it employs the high-temperature reaction between lime (CaO) and carbonaceous materials like coke or anthracite. At HANI<\/strong>, we have optimized the CaC2 smelting<\/strong> process to achieve maximum yield and energy efficiency. Our SAF for calcium carbide<\/strong> is engineered with a fully enclosed design, allowing for the collection and utilization of high-energy furnace gas. This technology provides a stable, large-scale production platform for the manufacturing of acetylene gas, PVC, and calcium cyanamide.<\/p>\n

A HANI Calcium Carbide Smelting Furnace<\/strong> is built for continuous, high-power operation. The Calcium Carbide Furnace<\/strong> utilizes the submerged arc principle, where the electrodes are buried deep in the charge, generating temperatures up to 2200\u00b0C. Our CaC2 smelting<\/strong> units are equipped with advanced Soderberg self-baking electrode systems and high-precision hydraulic control. By integrating intelligent power management and automated tapping machines, HANI\u2019s SAF for calcium carbide<\/strong> ensures the highest level of operational safety and production stability, meeting the needs of modern industrial chemical bases.<\/p>\n<\/div>\n

Chemical Basis of Calcium Carbide Production<\/h2>\n

The production of calcium carbide in a Calcium Carbide Smelting Furnace<\/strong> is a highly endothermic reaction that occurs in the Calcium Carbide Furnace<\/strong> hearth. The core CaC2 smelting<\/strong> reaction between lime and carbon (coke) requires intense electrical energy to overcome the high reaction enthalpy. HANI’s SAF for calcium carbide<\/strong> optimizes the heat balance by utilizing the radiant heat from the arc effectively within the material layer.<\/p>\n

Primary Reaction Mechanism:<\/p>\n

CaO + 3C \u2192 CaC2<\/sub> + CO \u2212 465.7 kJ\/mol<\/p>\n<\/div>\n

Scientific facts show that the quality of calcium carbide from a Calcium Carbide Smelting Furnace<\/strong> is determined by the purity of the lime and the carbon content of the coke. HANI’s CaC2 smelting<\/strong> process incorporates a high-temperature gas cleaning system to capture the CO gas, which can be used to pre-calcine lime, creating a circular energy economy in the SAF for calcium carbide<\/strong> plant. Our furnaces also use specialized water-cooled linings to resist the corrosive liquid carbide at 2000\u00b0C+.<\/p>\n<\/div>\n
