Calcined Petroleum Coke is a form of petroleum coke that has undergone high- temperature treatment to remove moisture, volatile organic compounds, and impurities. This process, known as calcination, results in a product with high carbon purity and improved physical and chemical properties. Advantage 1.High Carbon Content: Calcined petroleum coke typically has a high carbon content ranging from 98% to 99.5%. This high carbon content ensures excellent performance in carbon-related applications, such as anode production and steelmaking; 2. Low Ash and Sulfur Content: The calcination process reduces the ash and sulfur content in petroleum coke, making it suitable for applications that require low impurity levels. Low sulfur content is particularly important in steelmaking, as it helps minimize environmental emissions and improve product quality; 3.Consistent Quality: Manufacturers carefully control the calcination process to ensure consistent quality of the final product. This consistency allows users to rely on the properties of calcined petroleum coke for their specific applications.

Calcium Carbide Stones are a primary and unprocessed bulk form of Calcium Carbide, typically ranging in size from 15mm to 25mm. They are produced directly in an electric arc furnace at extreme temperatures (~2,200°C) from a mixture of lime and coke. This lump form is the foundational product from which other forms like granules or powder are derived, and it is primarily used in large-scale industrial applications such as acetylene generation for gas welding/cutting and as a desulfurizing agent in steelmaking. Wanding provides this high-quality, industrial-grade product to meet robust industrial demands. Shape: white crystals, black lumps, purple or gray cross-section for industrial products Available particle size: 1-4mm, 4-7mm, 7-15mm, 15-25mm, 25-50mm, 50-80mm, 80- 120mm. Gas production: 210L/KG, 230L/KG, 260L/KG, 295L/KG, depending on the size of the particles.  Physicochemical Properties: The solid of the ore is brown or black solid, the pure product is white crystal (containing CaC2 is purple). Density 2.22g/cm3, melting point 2300℃ (with CaC2 content), immediately react violently with water to generate acetylene and release heat, calcium carbide content of different melting point will also change.

Calcium Carbide 7-15mm is widely used in various industrial processes, including nitrogen fixation in cyanamide production and sulfur removal in the steelmaking industry. This chemical compound appears as a gray to black solid and exhibits high reactivity with water. Calcium Carbide is widely used in various industrial processes, including nitrogen fixation in cyanamide production and sulfur removal in the steelmaking industry. This chemical compound appears as a gray to black solid and exhibits high reactivity with water. With a density of approximately 2.22 g/cm³ and a molecular formula of CaC₂, it plays a crucial role in the production of acetylene, which is essential for oxyacetylene welding. In ladle treatment facilities, Calcium carbide 7-15 mm for acetylene production acts as an efficient deoxidizer and serves as a fuel to enhance the scrap ratio to liquid iron in steelmaking processes. The use of Calcium Carbide for Welding 7-15 mm (1) Acetylene from calcium carbide with water can synthesize many organic compounds. For example: synthetic rubber, artificial resin, acetone, ketene, carbon black, etc; At the same time, acetylene oxygen flame is widely used for metal welding and cutting. (2) When heating powdered calcium carbide with nitrogen, the reaction generates calcium cyanamide, which is called lime nitrogen. The cyanide melt generated by the reaction of heated lime nitrogen with table salt is used in gold mining and non-ferrous metal industries. (3) Calcium carbide itself can be used as a desulfurizer in the steel industry.

Calcium carbide granules are a key processed form of Calcium Carbide (CaC₂). Industrially produced in an electric arc furnace at ~2,200 °C, they are essential for generating acetylene, steelmaking, and more. Our industrial-grade product meets strict standards (GB209-2006) and is verified by international inspections (SGS/CIQ/BV). Wanding supplies this reliable, high-quality product for global industrial needs. Calcium Carbide Granule Applications Acetylene Gas Production: Generates a portable and on-demand fuel source for metal cutting/welding and chemical synthesis. Steelmaking (Desulfurizer): Efficiently removes sulfur impurities from molten iron/steel to improve product quality. Calcium Cyanamide Production: Serves as a key precursor for nitrogen fertilizers and various industrial chemicals. Other Industrial Uses: Assists in wastewater treatment (phosphate removal) and acts as a powerful desiccant.
