Reagent Injection System for Desulfurization Reactors

Product Specifications

Technical details and manufacturing context for Reagent Injection System

Definition

The Reagent Injection System is a critical component of the Molten Metal Desulfurization Reactor responsible for accurately metering and introducing chemical reagents (typically calcium-based compounds or other desulfurizing agents) into the molten metal bath. It ensures controlled reagent delivery to facilitate efficient sulfur removal through chemical reactions, maintaining optimal process conditions for steel quality improvement. The system is engineered for the basic metal manufacturing industry, specifically for desulfurization processes in steelmaking. It operates by pneumatically or mechanically conveying powdered or granular reagents from storage hoppers through injection lances or nozzles into the molten metal. The system uses controlled pressure and flow rates to ensure uniform dispersion of reagents throughout the metal bath, maximizing contact surface area for efficient desulfurization reactions. Key parameters include an injection pressure of 1.0–1.6 bar, reagent capacity of 500–2000 kg, injection lance diameter of 50–100 mm, flow rate of 5–20 L/min, injection accuracy of ±1%, operating temperature of 0–60 °C, power supply of 380–480 V AC (IEC 60038), power consumption of 5–15 kW, ingress protection of IP54–IP65 (IEC 60529), material grade 316L (ASTM A240), weight of 800–1500 kg, and dimensions of 2000×1500×1800 mm. The system is typically skid-mounted for ease of integration. Materials used include stainless steel (316L/310S), refractory-lined steel, and high-temperature ceramics. These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier. The system is designed for use in desulfurization reactors, and its performance depends on proper selection of reagents, operating conditions, and maintenance. Verification of model-specific values and standards is essential before procurement or installation.

Working Principle

The system operates by pneumatically or mechanically conveying powdered or granular reagents from storage hoppers through injection lances or nozzles into the molten metal. It uses controlled pressure and flow rates to ensure uniform dispersion of reagents throughout the metal bath, maximizing contact surface area for efficient desulfurization reactions. The injection pressure is typically maintained between 1.0 and 1.6 bar, and the flow rate is adjustable between 5 and 20 L/min to control the reagent addition rate. The system ensures consistent desulfurization with an injection accuracy of ±1%. The injection lance diameter ranges from 50 to 100 mm, allowing for adequate penetration and dispersion. The system is designed to operate within a temperature range of 0–60 °C for the control cabinet and pumps, and it requires a three-phase power supply of 380–480 V AC at 50/60 Hz. The power consumption depends on pump and heating requirements, typically between 5 and 15 kW. The system is protected against dust and water jets with an ingress protection rating of IP54–IP65. The materials used, such as stainless steel 316L, are corrosion-resistant for the molten metal environment.
