Description
Technical field
The present invention relates to a kind of material scraping plate, especially relate to a kind of material scraping plate for sintering machine, belong to the design and manufacturing technology field of metallurgical production equipment auxiliary equipment.
Background technology
At present, be improve the wearability of scraping plate for sintering machine, the domestic practice is all generally that on working face, built-up welding one deck antifriction alloy realizes with general steel plate or steel-casting for matrix.And when build-up wear-resistant alloy, no matter overlay cladding thickness has and how thickly all adopts disposable built-up welding to complete.The shortcoming of this method is that overlay cladding easily occurs penetrating crack, and when being in use subject to the extruding of material impacting and disintegrating machine, overlay cladding very easily peels off the block that comes off, thus affects material scraping plate using function and service life.And every maintenance down changes once described material scraping plate, all can produce sintering deposit and cause huge economic loss, what be unfavorable for that sintering deposit produces normally carries out.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of long service life, is not easy the material scraping plate for sintering machine occurring that wearing layer comes off in using.
: for the material scraping plate of sintering machine, comprise steel baseplate be coated with the abrasion-proof structure that one deck contains grid ribs in the working face side of described steel baseplate for solving the problems of the technologies described above adopted technical scheme.
Further, described abrasion-proof structure also comprises wearing layer, and described netted muscle is made up of grid frame, described wearing layer and be fusion syndeton between described grid frame and described steel baseplate.
The preferred embodiment of such scheme is, described fusion syndeton is welding connection structure.
Further, described grid frame is made up of the more than one piece steel purlin of the working face side being welded on described steel baseplate, and each described steel purlin is the working face side of the described steel baseplate of latticed layout.
The preferred embodiment of such scheme is, in each the steel purlin forming described grid frame, each the steel purlin be positioned at is longitudinally staggeredly arranged in the vertical.
Further, described wearing layer comprises transition zone and wearable overlay, described transition zone and described wearable overlay interlaced arrangement on the thickness direction of described material scraping plate; Between described transition zone and described wearable overlay, and be fusion syndeton between described wearable overlay and described steel baseplate.
Further, described wearable overlay is formed by the built-up welding of alloy wlding, and described transition zone is formed by the built-up welding of carbon steel wlding.
Further, the thickness of described wearable overlay is greater than the thickness of described transition zone.
Further, outermost one deck of described wearing layer is wearable overlay.
The invention has the beneficial effects as follows: by being coated with the cancellated abrasion-proof structure of one deck in the working face side of described steel baseplate, and in use procedure by this layer of cancellated abrasion-proof structure work.Like this, because the working face bearing friction is made up of cancellated wearing layer, thus make the working face of described material scraping plate, can not occur that because of the extruding of material impacting and disintegrating machine wearing layer peels off the situation of the block that comes off in real work, reach the object effectively extending described material scraping plate long service life.
Accompanying drawing explanation
Fig. 1 is the front view of the present invention for the material scraping plate of sintering machine;
Fig. 2 is the A-A sectional view of Fig. 1.
Be labeled as in figure: steel baseplate 1, abrasion-proof structure 2, grid frame 3, wearing layer 4, steel purlin 5, transition zone 6, wearable overlay 7.
Detailed description of the invention
Be a kind of long service life provided by the invention as shown in Figure 1 and Figure 2, in using, be not easy the material scraping plate for sintering machine occurring that wearing layer comes off.Described material scraping plate comprises steel baseplate 1, is coated with the abrasion-proof structure 2 that one deck contains grid ribs in the working face side of described steel baseplate 1.Be coated with above by the working face side at described steel baseplate 1 abrasion-proof structure 2 that one deck contains grid ribs, and work at the abrasion-proof structure 2 that use procedure contains grid ribs by this.Like this, because described abrasion-proof structure 2 has cancellated dowel, thus make described abrasion-proof structure 2 when covering the working face side of described steel baseplate 1, be not easy to occur penetrating crack, and the abrasion-proof structure 2 that the working face bearing friction contains grid ribs by this is just formed, and then make the working face of described material scraping plate, can not occur that because of the extruding of material impacting and disintegrating machine abrasion-proof structure 2 peels off the situation of the block that comes off in real work, reach the object effectively extending described material scraping plate long service life.
In above-mentioned embodiment, conveniently described abrasion-proof structure 2 covers described steel baseplate 1, be beneficial to the making of postorder, further can improve again the anti-crack ability of this abrasion-proof structure 2 simultaneously, described abrasion-proof structure 2 also comprises wearing layer 4, described netted muscle is made up of grid frame 3, described wearing layer 4 and between described grid frame 3 and described steel baseplate 1 for fuse syndeton; Described grid frame 3 is made up of the more than one piece steel purlin 5 of the working face side being welded on described steel baseplate 1, the described working face side of each steel purlin 5 in the described steel baseplate 1 of latticed layout; In each the steel purlin 5 forming described grid frame 3, each the steel purlin 5 be positioned at is longitudinally staggeredly arranged in the vertical.Like this, adopt steel purlin 5 to be also staggeredly arranged in the vertical by each the steel purlin 5 be positioned at longitudinally, the anti-crack ability of described grid ribs can be improved to greatest extent, and then the anti-crack ability of wearing layer 4 described in improving.
Use for reference in prior art, fusion syndeton is generally the feature of welding connection structure, and in order to reduce production cost, wearing layer 4 of the present invention also adopts built-up welding mode.In weld deposit process, the normal penetrating crack occurred in prior art is there is in order to avoid wearing layer 4 to greatest extent, described wearing layer 4 comprises transition zone 6 and wearable overlay 7, described transition zone 6 and described wearable overlay 7 interlaced arrangement on the thickness direction of described material scraping plate; Between described transition zone 6 and described wearable overlay 7, and be fusion syndeton between described wearable overlay 7 and described steel baseplate 1; Described wearable overlay 7 is formed by the built-up welding of alloy wlding, and described transition zone 6 is formed by the built-up welding of carbon steel wlding.Like this, because the cracking resistance of carbon steel is more much better than the cracking resistance of steel alloy, thus the transition zone 6 of carbon steel wlding built-up welding is played improve wearing layer 4 to resist the ability of penetrating crack, reach the phenomenon avoiding wearing layer 4 to occur penetrating crack to greatest extent in weld deposit process.
Meanwhile, in order to not reduce described wearing layer 4 abrasion-resistance, the thickness of described wearable overlay 7 is arranged more much bigger than the thickness of described transition zone 6; And outermost one deck of described wearing layer 4 is set to wearable overlay 7.
