Abstract
The invention discloses a composite embedding electric bucket tooth and a manufacturing method thereof. A first metal ceramic tooth rod is embedded in the front part of a high-manganese steel or alloy steel tooth base; and second metal ceramic tooth rods are respectively embedded in two sides of the front part of the high-manganese steel or alloy steel tooth base and in grooves. A mold is manufactured according to a up-down parting mode; the manufactured mold is embedded in a sand mold; a molding cavity is formed; a prepared ceramic body is fixed on the surface of the sand mold; after the ceramic body is firmly fixed without generating the loosening or falling condition, the casting is prepared through box closing; after high-manganese steel or alloy steel is discharged from a furnace, the high-manganese steel or alloy steel is poured in a bucket tooth molding cavity for casting after standing by 2-4 minutes, and the casting temperature is controlled within 1350-1380 DEG C; when the temperature in the molding cavity is lower than 200 DEG C after the casting is finished, a box is opened; attached sand is removed from a casting after box opening, and gates and risers are removed; a cleaned bucket tooth is put in a heating furnace for insulation by 3-5 hours under the condition of 1050-1080 DEG C; and after the insulation time is reached, the casting is discharged from the furnace for water toughening treatment.
Description
Technical field
The present invention relates to a kind of compound castingin electric bucket tooth and preparation method thereof, belong to wear-resisting electric bucket tooth technical field.
Background technology
Power shovel and hydraulic shovel bucket tooth, in mining process, directly contact with ground, Ore, are subject to the extruding of Ore, wash away, and wear and tear very serious.Meanwhile, also suffer from huge shock loading, belong to the easily worn part of power shovel.In large medium-size mine at home, more than 8 cubic metres power shovels, the hydraulic shovel be on active service at present have more than 1000, because not reaching requirement the service life of bucket tooth, year, economic loss was at about 20,000,000 yuan.Simultaneously as change bucket tooth frequently, cause shutdown, stop production and bring bigger indirect loss.
In order to improve the wearability of bucket tooth, current Chinese scholars is by studying, substantially take three kinds of methods, first all antifriction alloy steel being to adopt hard high-strength, such as containing molybdenum, titanium, chromium, nickel steel alloy, this kind of method makes bucket tooth cost high, and the bucket tooth life-span does not significantly improve；The second is at bucket tooth tip build-up wear-resistant layer, and mainly containing titanium carbide Hardmetal materials, but this kind of method makes the finite thickness of wearing layer, and the easy fragmentation of overlay cladding and peeling, do not receive obvious effect yet.Another kind is most advanced to bucket tooth for rich chromium cast iron block castingin, and this method is expected the high rigidity advantage utilizing rich chromium cast iron, but actually used in there is a problem, rich chromium cast iron belongs to two kinds of different materials of physical property from potassium steel, and heat treatment mode is different.These two kinds of materials are placed into and can not organically combine together, can only play a kind of material advantage and weaken another kind of material advantage so that product can not normally use, it is easy to occur that insert comes off problem.
Additionally somebody using hard alloy as rack, potassium steel is as tooth base, hard alloy rack is embedded in the excavator bucket teeth that the front end of potassium steel tooth base makes, this kind of bucket tooth lightweight structure is simple, except crown steel matrix is thicker arrange hard alloy except, all the other positions are relatively thin because of skin, it is impossible to imbedding hard alloy.Although so the adhesion of hard alloy and potassium steel increases, but owing to whole bucket tooth only has the front portion of tooth to inlay rack, the both sides of bucket tooth are all also potassium steel, the abrasion resistance of potassium steel than hard alloy inferior a lot, before ceramic metal rack is but without abrasion, potassium steel tooth base polishes already, have impact on the performance of hard alloy effect, thus failing to play the purpose in the service life of intended prolongation bucket tooth.
Summary of the invention
The invention aims to solve above-mentioned prior art Problems existing, one is that the steel bonded carbide (wear-proof metal ceramic body) adopting hard high-strength is as wear-resisting main material；Two is that wear-proof metal ceramic body is integrated with potassium steel and the organic metallurgical binding of steel alloy by the mode of compound castingin；Three is arrange wear-proof metal ceramic at the place foremost of bucket tooth and two upper and lower side places of bucket tooth.By the electric bucket tooth that this kind of method is manufactured, compared with common potassium steel material, reach to extend the purpose of bucket tooth 2--3 times of effect in service life.
It is an object of the invention to be achieved through the following technical solutions:
A kind of compound castingin electric bucket tooth, including the first ceramic metal rack, the second ceramic metal rack and potassium steel or alloy steel-tooth base, the centre position of described potassium steel or alloy steel-tooth base front portion is provided with groove, the front portion of described potassium steel or alloy steel-tooth base is inlaid with the first ceramic metal rack, is all inlaid with the second ceramic metal rack in the front part sides of described potassium steel or alloy steel-tooth base and groove.
A kind of compound castingin electric bucket tooth, including the first ceramic metal rack, the second ceramic metal rack and potassium steel or alloy steel-tooth base, the front portion of described potassium steel or alloy steel-tooth base is inlaid with the first ceramic metal rack, and the front part sides of described potassium steel or alloy steel-tooth base is all inlaid with the second ceramic metal rack.
The manufacture method of compound castingin electric bucket tooth of the present invention,
Step one, on the front end of potassium steel or alloy steel-tooth base and two sides, arrange the first ceramic metal rack and the second ceramic metal rack；
Step 2, in order to ceramic body is imbedded in bucket tooth, make mould according to the mode of upper and lower typing；
Step 3, the mould embedment sand mold that will make, make die cavity, ready ceramic body be fixed to mould surface.
Step 4, confirmation ceramic body are fixed, and after not havinging the situation of dropping that gets loose, mould assembling prepares casting；
After step 5, potassium steel or steel alloy are come out of the stove, standing and within 2～4 minutes, pour bucket tooth die cavity into and cast, cast temperature controls at 1350～1380 DEG C；
Step 6, cast after can open sandbox when type cavity temperature is lower than 200 DEG C；
Step 7, unpack after foundry goods remove scab, remove cast gate rising head；
Step 8, the trolley sawtooth casting cleaned out being loaded heating furnace, be incubated under 1050～1080 DEG C of conditions, temperature retention time was at 3～5 hours；
After step 9, temperature retention time arrive, foundry goods is come out of the stove and is carried out water-tenacity treatment；
Foundry goods after step 10, water-tenacity treatment is polished cleaning further, and mopping is finished product.
The electric bucket tooth of the present invention, high strength and high hardness ceramic metal rack and potassium steel bucket tooth base material by being distributed to position, bucket tooth tip and both side surface are constituted, and are arranged in the ceramic metal on end face through high temperature casting and potassium steel matrix metallurgical binding, fuse into one.Composite casting Tooth structure includes being distributed in that bucket tooth is most advanced and the cermet body of bucket tooth both side surface and potassium steel or alloy steel matrix.The layout of cermet body takes interlaced arrangement mode, not only improves the wearability of bucket tooth but also save the consumption of high-abrasive material so that cermet body and base material are combined closely, and the service life of electric bucket tooth improves two to three times.
