Tunnel Kilns. A tunnel kiln should be used when you're producing a constant, high-volume production line. The variable cycle time of tunnel kilns makes them ideal for integration into a continuous and/or automated production line. Tunnel kilns are low maintenance and require less manual labour to operate, freeing up employees.
With reduction temperature increasing, the metallization ratio of produced sponge iron is proportionally increasing, and the outer diameter of the sponge iron ring is gradually decreasing.
