[0045] The second aspect of the present invention relates to a method for preparing the high-temperature abrasion-resistant pusher plate of a garbage incinerator as described in the first aspect of the present invention, which includes:

[0046] Step B, in the closed liquid forging die (conventional) on the hydraulic press, alternately lay Al-Fe on the upper surface 11 and the lower surface 12 of the pusher plate 1 from inside to outside 3 o 4 Mixed powder 21 and Ti-C mixed powder 22, the layer next to the pusher plate and the lower surface is Al-Fe 3 o 4 Mixed powder 21, the outermost layer is Ti-C mixed powder 22, see figure 2 ;

[0047] Step C, alternately laying Al-Fe 3 o 4 The mixed powder 21 and the Ti-C mixed powder 22 are pressed together to form Al-Fe alloys laid alternately from the inside to the outside on the upper surface 11 and the lower surface 12 of the pusher plate 1. 3 o 4 Powder blank 31 and Ti-C powder blank 32, the layer next to the pusher plate an...

Embodiment 1

[0077] (1) Prepare Ti+C=TiC self-propagating powder material and 8Al+3Fe respectively according to the principle of self-propagating reaction 3 o 4 = 4 Al 2 o 3 +9Fe self-spreading powder material (powder particle size is 200-300 mesh), mix the respective spreading powder materials evenly to obtain Al-Fe 3 o 4 Mixed powder and Ti-C mixed powder;

[0078] (2) The upper surface 11 and the lower surface 12 of the pushing plate 1 in the closed liquid forging die on the hydraulic press (see figure 1 ) into Al-Fe in turn 3 o 4 The mixed powder 21 and the Ti-C mixed powder 22 are laid repeatedly and alternately in 8 layers. The order of the mixed powder layers laid alternately on the upper surface 11 and the lower surface 12 of the pushing plate 1 from the inside to the outside is: Al-Fe 3 o 4 Mixed powder 21 / Ti-C mixed powder 22 / Al-Fe 3 o 4 Mixed powder 21 / Ti-C mixed powder 22 / Al-Fe 3 o 4 Mixed powder 21 / Ti-C mixed powder 22 / Al-Fe 3 o 4Mixed powder 21 / Ti-C mixed powder...

Embodiment 2

[0085] The difference between step (2) of this embodiment and embodiment 1 is that 6 layers are alternately laid repeatedly, and the order of the mixed powder layers laid alternately from the inside to the outside on the upper surface 11 and lower surface 12 of the pushing plate 1 is: Al-Fe 3 o 4 Mixed powder 21 / Ti-C mixed powder 22 / Al-Fe 3 o 4 Mixed powder 21 / Ti-C mixed powder 22 / Al-Fe 3 o 4 Mixed powder 21 / Ti-C mixed powder 22;

[0086] The difference between step (3) of this embodiment and embodiment 1 is that the order of the mixed powder layers laid alternately from the inside to the outside on the upper surface 11 and the lower surface 12 of the pusher plate 1 is: Al-Fe 3 o 4 Powder blank 31 / Ti-C powder blank 32 / Al-Fe 3 o 4 Powder blank 31 / Ti-C powder blank 32 / Al-Fe 3 o 4 Powder blank 31 / Ti-C powder blank 32;

[0087] The difference between step (4) of this embodiment and embodiment 1 is that the TiC / Fe-Al that constitutes the high-temperature abrasion-resistan...

Abstract

The invention belongs to the technical field of surface engineering and relates to a high-temperature corrosion-resistant push plate of a garbage incinerator. The push plate comprises a push plate matrix, and TiC / Fe-Al2O3 high density ceramic-based composite material coatings cladded to the upper and lower surfaces of the push plate. The TiC / Fe-Al2O3 high density ceramic-based composite material coating is formed by cladding a Fe-Al2O3 ceramic-based composite material layer and a TiC metal ceramic layer as coating materials to the upper and lower surfaces of the push plate layer by layer alternately successively. The push plate has excellent high-temperature corrosion resistance, can meet severe service conditions in the garbage incinerator and is long in service life. The invention further relates to a preparation method of the high-temperature corrosion-resistant push plate of the garbage incinerator. The method is simple in process and low in cost and can manufacture the high-temperature corrosion-resistant push plate quickly at one time. The method has the advantages of being energy-saving, quick, efficient and the like.

Description

technical field [0001] The invention belongs to the technical field of surface engineering, and relates to a high-temperature and abrasion-resistant pushing plate for a garbage incinerator and a preparation method thereof. Background technique [0002] The pusher plate of the garbage incinerator transports burning garbage under the conditions of high temperature, corrosive gas and friction and wear in the furnace. The surface in contact with the garbage is severely abrasive, and the other side is more severely corroded. The short service life affects the long-term stable service of the incinerator. It is urgent to improve the manufacturing technology and increase the service period. Contents of the invention [0003] One of the objectives of the present invention is to overcome the above-mentioned disadvantages and provide a high-temperature and abrasive-resistant push plate for a garbage incinerator. Abrasive performance, can meet the harsh service conditions in waste in...
