  • Commodity name: Tunnel Kiln for Metal Powder Sintering: High-Density Output, Uniform Structure, Energy Efficiency

Category:

Description

Tunnel kilns are pivotal in metal powder sintering, delivering high-density outputs through controlled heating. They ensure uniform microstructures across parts and boost energy efficiency via optimized heat circulation, merging precision with cost-effectiveness for industrial metal processing.

1. High-Density Output
Precise temperature and pressure regulation during sintering promotes strong particle bonding, resulting in dense, low-porosity metal components. This enhances mechanical strength, critical for load-bearing industrial parts.
2. Uniform Structure
Consistent heat distribution along the tunnel ensures even sintering. Each part develops identical grain structures, reducing performance variations and ensuring reliability in batch production.
3. Energy Efficiency
Heat recovery systems reuse waste heat from cooling zones, cutting fuel needs. Efficient burner controls minimize energy loss, lowering operational costs while supporting sustainable manufacturing.
4. Scalable Continuous Production
Uninterrupted workflow enables high-volume output. The tunnel design accommodates varied part sizes, making it adaptable to diverse industrial demands without compromising sintering quality.

FAQ

FAQ

What is the difference between a tunnel kiln and a traditional kiln?


FAQ
Tunnel kiln: Automated continuous production, suitable for large-scale, standardized brick and tile manufacturing, low energy consumption but high investment. - Rotary kiln: Intermittent production, high flexibility, suitable for small batches or special brick types, but high energy consumption and labor intensity.
FAQ

What are the fuel options for tunnel kilns?


FAQ
Common fuels include coal (requires supporting desulfurization facilities), natural gas, biomass pellets, gas generator gas, etc. The specific choice depends on local energy policies and costs.
FAQ

What is the construction cycle and investment cost of a tunnel kiln?


FAQ
The construction cycle of a standard tunnel kiln (80-150 meters long) is usually 3-6 months, with an investment of about 2-8 million yuan (large differences depending on the scale). - In long-term operation, the energy-saving advantage can quickly recover costs.
FAQ

How can tunnel kilns achieve environmental protection standards?


FAQ
Install desulfurization and dust removal equipment (such as wet electrostatic precipitator, SCR denitrification). Use low-sulfur fuel or clean energy. Optimize the combustion process to reduce the generation of nitrogen oxides.
FAQ

Which is more suitable for brick and tile production, shuttle kiln or tunnel kiln?


FAQ
Shuttle kiln: suitable for small batches, high value-added products, high flexibility, but low single output. Tunnel kiln: suitable for continuous large-scale production, lower energy consumption, but high investment cost and difficult process adjustment.
