AI Technical Summary

Benefits of technology

This technology described in this patents allows for efficient use of energy during processing operations without requiring multiple stages or expensive equipment like an oven-fired electric arc furnace (EAF). By utilizing both heating/cooling cycles alone instead of just one, these methods are more effective at achieving desired results compared to traditional techniques that require several different types of tools.

Problems solved by technology

This patented technical problem addressed in this patents relates to disposal of worn out rollers due to their difficulty being shredded down during recovery processes. Existing methods involve burning them away at great expenses and causing environmental concerns. Blending new material instead of discarding old ones improves efficiency while reducing costs compared to traditional ways like dumping them on landfill sites.

Embodiment Construction

[0017] see figure 1 , the figure shows the appearance of an overall structure of an embodiment of the heating device for crushing large steel pieces proposed by the present invention. The device has a substantially rectangular combustion furnace 1 in appearance, and a wing fan 14 is arranged on the vertical surface along the longitudinal direction of the combustion furnace 1 . The upper part of the combustion furnace 1 is a closed surface 13 with a chimney 12, and a fire grate 11 is installed in its inner cavity and below the wing fan 14, and a blower is installed on one side of the bottom of the fire grate 11 (not given in the accompanying drawings) . In order to prevent the heat energy in the combustion furnace 1 from spreading outwards as much as possible, an insulating layer made of refractory material is provided on the inner periphery of the combustion furnace 1 and the inner side of the wing fan 14 .

[0018] The lower edge of the wing leaf 14 is equipped with a transver
