Xiangye Coal Injection Lance (Blast Furnace Pulverized Coal Lance) Ф34×4 Technical Analysis
1. Product Specifications and Structure
Model and Dimensions: Heat-resistant seamless steel pipe with an outer diameter of 34mm and wall thickness of 4mm, compatible with blast furnace coal injection systems, customizable length (commonly 1700mm).

Material: Made of 2520 heat-resistant steel (e.g., SUS310S), treated for wear resistance, high-temperature oxidation resistance, and resistance to pulverized coal erosion.
Connection Method: Straight or inclined insertion design, with an insertion angle typically between 12° and 14°, to avoid direct impact of coal flow on the tuyere.

2. Core Functions and Advantages
Coal Injection Performance: Stable delivery of pulverized coal to the blast furnace tuyere, supporting high injection rates (e.g., 300kg/ton of iron), reducing ironmaking costs.
Durability: Short heated section, resistant to deformation, long service life and repairable, reducing blast furnace downtime frequency.

3. Application Scenarios
Compatible Systems: Specifically designed for blast furnace coal injection in steel plants, requires supporting equipment such as pulverized coal distributors and ball valves.
Operational Requirements: Precise control of insertion depth and angle to avoid erosion of the blowpipe or tuyere by coal flow.
4. Manufacturer and Selection Recommendations
Manufacturer: Xiangye Environmental Protection Equipment Co., Ltd., offering customized services (e.g., dual-tube design for oxygen-coal lances).
Selection Points: Choose insertion method (straight/inclined) based on coal particle size, injection pressure, and tuyere structure.
