Abstract
The invention relates to a wear-resisting casting and a production process thereof. The wear-resisting casting comprises a hammer head and a hammer handle. The hammer handle is a high-toughness hammer handle, and the hammer head is a high-wear-resistance hammer head. The hammer head and the hammer handle are recombined into a whole through a melting layer between the hammer head and the hammer handle. The no-medium three-dimensional composite casting process with two kinds of liquid is adopted, one material of high toughness and one material of high hardness are recombined into a whole through the melting layer between the two materials, and therefore the composite strength is high, the composite area is 100%, the casting has the high toughness and the high wear-resistance, and the defects that an existing casting is single in material and can not have the high toughness and the high wear-resistance at the same time can be overcome effectively.
Description
Technical field
The present invention relates to a kind of product casting field, relate in particular to a kind of wear resistance castings and production technology thereof.
Background technology
Prior art has been reported to adopt has medium bimetallic casting process to manufacture composite wear-resistant casting parts, this type of composite wear-resistant casting parts has guaranteed the good abrasion resistance of wear-resisting part, also there is the advantage that overall flexibility is strong, but the wear resistance castings combined strength bination that this technique is manufactured is not high, compound area only has 80%, thereby its product in use remains larger potential safety hazard, so it only can be for the wear-resistant foundry goods under inactive state, liner plate for example, and wear-resistant foundry goods in motion for example tup can not be suitable for.
Summary of the invention
The object of the invention is to provide a kind of can meet obdurability simultaneously, high-wearing feature requires and the large composite wear-resistant casting parts of compound area, and another object is to provide its manufacture method.
Technical scheme of the present invention is: a kind of wear resistance castings, comprise tup and hammer handle, described hammer handle is obdurability hammer handle, described tup is high wear-resistant tup, described tup and hammer handle by between the two dissolve layer compound as a whole.
Described hammer handle tow sides are provided with circular hole.
Described obdurability hammer handle is that carbon steel or low-alloy steel casting form, and hardness is HRC30.
The wear-resistant tup of described height is that cast steel with high chromium casting forms, and hardness is HRC60-64.
A production technology for wear resistance castings, concrete production stage is as follows:
1) first adopt three-dimensional sandbox planar design, and the material of obdurability material and two kinds of different performances of high hardness material is carried out to twin furnace smelting, smelt into molten metal;
2) then without under ambient condition, the high wear-resistant material metal liquid of first casting, cast temperature 1400-1500 ℃, then the obdurability material metal liquid of casting, cast temperature 1450-1550 ℃, casting time 1-8 minute, after shaping, knockout processing is carried out in insulation;
3) finally foundry goods is heat-treated with the later stage and cleared up.
Described obdurability material metal liquid is carbon steel liquation, and the percentage of described carbon steel ingredient is: C0.3-0.5%, Si0.5-0.8%, Mn0.6-0.9%, P≤0.08%, S≤0.05%, Mo0.2-0.5%, Al0.1-0.5%, rare earth 0.15-0.5%.
The wear-resistant material metal liquid of described height is cast steel with high chromium liquation, and the percentage of described cast steel with high chromium ingredient is: C2.3-2.8%, Si0.6-0.9%, Mn0.5-0.8%, P≤0.07%, S≤0.05%, Mo0.3-1.2%, Al0.1-0.5%, rare earth 0.15-0.5%.
The invention has the advantages that: adopt non-medium double-liquid three-dimensional composite casting technique, the material of two kinds of obdurabilities and high rigidity different performance by centre dissolve layer compound as a whole, combined strength bination jail, compound area reaches 100%, make the existing high tenacity of product have again strong wearability, effectively solved existing product material single, both deficiencies that can not have concurrently of obdurability, strong wearability.Except the wear resistance castings for inactive state, be also effectively applicable to the wear resistance castings of motion state: such as tup, bar etc., makes wear resistance castings have qualitative leap.This technique is applicable to the manufacture of the wear-resisting spare part product in the field crushing and grinding equipments such as cement, electric power, mine.This technique product technical parameter: the hardness of toughness material should be in HRC30 left and right, and the assembling position that is generally used in workpiece enters hammer handle; High hardness material hardness reaches HRC60-64, is used in the working position of workpiece, as tup.
The specific embodiment
With 100kg bar, be fabricated to example, the present invention illustrated better:
Comprise tup and hammer handle, described hammer handle is obdurability hammer handle, described tup is high wear-resistant tup, described tup and hammer handle by between the two dissolve layer compound as a whole, described hammer handle tow sides are provided with circular hole, and described obdurability hammer handle is that carbon steel casting forms, and hardness is HRC30, the wear-resistant tup of described height is that cast steel with high chromium casting forms, and hardness is HRC60-64.
Concrete production stage is as follows:
1) first adopt three-dimensional sandbox planar design, and the material of carbon steel and two kinds of different performances of cast steel with high chromium is carried out to twin furnace smelting, smelt into molten metal;
2) then without under ambient condition, the cast steel with high chromium molten metal of first casting, 1500 ℃ of cast temperatures, then the carbon steel molten metal of casting, 1550 ℃ of cast temperatures, casting time 8 minutes, after shaping, knockout processing is carried out in insulation;
3) finally foundry goods is heat-treated with the later stage and cleared up.
The percentage of described carbon steel ingredient is: C0.3-0.5%, Si0.5-0.8%, Mn0.6-0.9%, P≤0.08%, S≤0.05%, Mo0.2-0.5%, Al0.1-0.5%, rare earth 0.15-0.5%.
The percentage of described cast steel with high chromium ingredient is: C2.3-2.8%, Si0.6-0.9%, Mn0.5-0.8%, P≤0.07%, S≤0.05%, Mo0.3-1.2%, Al0.1-0.5%, rare earth 0.15-0.5%.
The above, be only preferred embodiment of the present invention, and any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
