At least one set of material pressing mechanisms is arranged on each side of the supporting frames to compact the sintering material on the sintering trolley. By adjusting the material pressing position of the material pressing mechanisms, a density difference can be formed between the compacted part and the un-compacted part, and the shrinkage rate of the compacted part after sintering can be reduced. By adjusting the material pressing angle of the material pressing mechanisms, the resistance of the sintering material passing through the material pressing mechanisms during the pressing process can be reduced, and the surface shape of the sintered material after pressing can be changed. By adjusting the material pressing height of the material pressing mechanisms, the height of the sintering material in the sintering trolley can be adapted, and the pressure of the sintering material exerted by the material pressing mechanisms can be adjusted. By adjusting the material pressing position, the material pressing angle and the material pressing height of the material pressing mechanisms, a better compacting effect can be achieved, so that the influence of the edge effect on the sintering material can be reduced.

Description

TECHNICAL FIELD

[0001] The present application relates to high-temperature sintering equipment technical field, and particularly relates to a sintering material pressing device. BACKGROUND

[0002] In recent years, with the increasing proportion of imported ore, sintering of rich ore powder has become a widely used sintering technology, and high-proportion rich ore powder sintering has also promoted the further development of thick material layer sintering. Before sintering, the mixture containing rich ore powder is uniformly arranged on the sintering trolley through the distributor. However, at the edge of the sintering trolley, due to the loose material and large void ratio, the material shrinks and separates from the trolley deck during the sintering process to form an edge joint, causing the edge resistance to be small during the sintering process, the airflow to be short-circuited, the wind speed to be significantly increased, and the edge effect to be formed, thereby affecting the sintering quality.

[0003] Currently, there are mainly three methods to suppress the edge effect:

[0004] (1) thickening the edge material and the edge material, and increasing the edge material density;

[0005] (2) increasing the edge ignition point temperature;

[0006] (3) improving the deck structure.

[0007] The second method has high energy consumption and is not easy to control, so it is difficult to implement. The third method can alleviate the edge effect to some extent, but there is still a gap between the material surface and the trolley baffle, and the effect of suppressing the edge effect is limited.

Each pressing mechanism 3 is installed on the support frame 2 at one end and abuts against the sintering material on the sintering trolley 1 at the other end. The support frame 2 is used to support the pressing mechanism 3. At least one group of pressing mechanisms 3 is arranged on each of the left and right sides of the support frame 2 to compact the sintering material on the sintering trolley 1. By adjusting the pressing position of the pressing mechanism 3, a density difference can be formed between the compacted part and the un-compacted part, and the density of the sintering material in the compacted part can be increased, and the shrinkage rate of the compacted part after sintering can be reduced. The device can also be applied to sintering trolleys 1 of different widths, thereby improving the applicability of the device. By adjusting the pressing angle of the pressing mechanism 3, the resistance of the sintering material passing through the pressing mechanism during pressing can be reduced, and the surface shape of the sintered material after pressing can be changed. By adjusting the pressing height of the pressing mechanism 3, the height of the sintering material in the sintering trolley 1 can be adapted, and the pressure of the pressing mechanism 3 on the sintering material can be adjusted. By adjusting the pressing position, pressing angle and pressing height of the pressing mechanism 3, a better compaction effect can be achieved, thereby reducing the influence of the edge effect on the sintering material.

[0038] In the embodiment, two groups of material pressing mechanisms 3 are arranged on the support frame 2, and are respectively arranged above the upper sides of the two side walls of the sintering trolley 1, so as to compact the sintering material at the edges of the sintering trolley, and increase the density of the sintering material at the edges, thereby reducing the shrinkage of the sintering material at the edges and reducing the edge effect in the sintering process.
