Xiangye Coal Lance (Steel Mill Pulverized Coal Lance) Ф34×4 Technical Analysis
1. Product Specifications and Structure
Model and Dimensions: Heat-resistant seamless steel pipe with outer diameter 34mm and wall thickness 4mm, suitable for blast furnace coal injection systems, length is customizable (common size is 1700mm).
Material: Made of 2520 heat-resistant steel (e.g., SUS310S), treated for wear resistance, with high-temperature oxidation resistance and resistance to pulverized coal erosion.
Connection Method: Straight insertion or oblique insertion design, with insertion angle usually ranging from 12° to 14°, to avoid direct blowing of pulverized coal flow onto the tuyere.
2. Core Functions and Advantages
Coal Injection Performance: Stably transports pulverized coal to the blast furnace tuyere, supporting large injection volume (e.g., 300kg per ton of iron), reducing ironmaking costs.
Durability: Short heat-affected zone, not easy to deform, long service life and repairable, reducing the frequency of blast furnace shutdowns for maintenance.
3. Application Scenarios
Suitable Systems: Specifically used for blast furnace coal injection in steel mills, needs to be matched with equipment such as pulverized coal distributors and ball valves.
Operation Requirements: Insertion depth and angle need to be precisely controlled to avoid pulverized coal flow eroding the straight blowing pipe or tuyere.
4. Manufacturer and Selection Suggestions
Manufacturer: Xiangye Environmental Protection Equipment Co., Ltd., provides customized services (e.g., dual-tube design for oxygen-coal lances).
Selection Key Points: Insertion method (straight insertion/oblique insertion) should be selected according to pulverized coal particle size, injection pressure and tuyere structure.
If technical parameters or installation guidelines are needed, you can contact the manufacturer to obtain detailed documents.
