AI Technical Summary
The existing cement kiln wear-resistant layer has a large number of rake nails welded together, and the welds are prone to loosening, resulting in insufficient firmness and affecting the service life of the wear-resistant layer.
The structure adopts a swallow-shaped composite low thermal conductivity ramming material layer, including swallow-shaped rake nails and connecting components. The fixing frame of the swallow-shaped rake nails is designed as a planar structure to fit the wall, increasing the welding area. The wave-shaped support frame increases the contact area, and the tightness is adjusted by the connecting components to enhance the structural stability.
It improves welding strength and overall connection strength, enhances the stability of the wear-resistant layer, extends the service life of the wear-resistant layer, reduces heat transfer, and improves the practicality of the wear-resistant layer in cement kilns.
