The use of high-quality graphitized petroleum coke recarburizers can bring enterprises comprehensive economic benefits in multiple aspects, including reducing production costs, improving product quality, optimizing production efficiency, and enhancing environmental protection benefits. The specific analysis is as follows:
I. Reducing Production Costs and Improving Material Utilization
Reducing Pig Iron Consumption: High-quality graphitized petroleum coke recarburizers, characterized by high fixed carbon content (usually ≥98%) and low impurities, can effectively replace the carbon source in pig iron. According to industry data, using this recarburizer can reduce pig iron consumption by 20%-40%, lowering the cost per ton of castings by approximately 300-500 yuan. For example, a foundry enterprise saved over one million yuan in annual pig iron procurement costs by optimizing the recarburizer ratio.
Enhancing Absorption Rate: Graphitization treatment enables carbon atoms to form an ordered layered structure, increasing the absorption rate from 60% of ordinary recarburizers to 90%-95%. This means that less recarburizer is required to achieve the target carbon content, further reducing material costs. For instance, in electric arc furnace steelmaking, adding 0.1%-0.3% of graphitized recarburizer can adjust the carbon content in molten steel while shortening the smelting time by 15-20 minutes and reducing energy consumption.
II. Improving Product Quality and Enhancing Market Competitiveness
Enhancing Casting Performance: The graphite microcrystals in high-quality graphitized petroleum coke recarburizers can serve as crystallization nuclei, promoting uniform growth of graphite flakes in cast iron. In gray cast iron, this can increase tensile strength by 15%-25%; in ductile iron, it can improve nodularity by 10%-20%. For example, after switching to this recarburizer, a manufacturer of automotive engine cylinder blocks reduced the casting defect rate from 15% to 3%, significantly improving product yield.
Meeting High-End Demands: The low sulfur (≤0.05%) and low nitrogen (≤400ppm) characteristics make graphitized petroleum coke recarburizers essential materials for producing high-end automotive castings, wind power equipment, and other critical components. Using this recarburizer can prevent casting defects such as cracks and porosity caused by sulfur and nitrogen impurities, enhancing product value.
III. Optimizing Production Efficiency and Shortening Production Cycles
Increasing Smelting Speed: During steelmaking, high-quality graphitized petroleum coke recarburizers can rapidly dissolve and uniformly distribute, reducing smelting time. For example, a steel mill shortened its electric arc furnace smelting cycle by 15%-20% after using this recarburizer, increasing annual steel output by over 10,000 tons.
Stabilizing Production Processes: The high purity and low impurities of the recarburizer prevent oxidation and degradation at high temperatures, reducing production fluctuations. For instance, in continuous casting, using this recarburizer can maintain stable carbon content in molten iron, avoiding casting quality issues caused by carbon content fluctuations.
IV. Enhancing Environmental Protection Benefits and Meeting Sustainable Development Requirements
Reducing Pollution Emissions: The low sulfur and low nitrogen characteristics of graphitized petroleum coke recarburizers significantly reduce emissions of sulfur dioxide and nitrogen oxides during combustion. For example, after using this recarburizer, a foundry reduced its flue gas desulfurization costs by 40% and cut annual sulfur dioxide emissions by dozens of tons.
Promoting Resource Recycling: During the production of graphitized petroleum coke recarburizers, waste heat can be recovered for power generation, saving 300 kWh of electricity per ton of product. Additionally, tail gas can be supplied to other industrial sectors (such as ceramic plants) as fuel, achieving efficient resource utilization. For example, through a circular economy model, an eco-industrial park reduced carbon emissions by 1.2 tons per ton of recarburizer produced.
