Abstract
The utility model adopts the fusion casting technique to integrally fuse and cast a ductile carbon steel flat hammer body casting together with highly wear-resistant alloy materials. Therefore, the flat hammer has the advantages of ductility and high wear resistance, overcomes the shortage that traditional high manganese steel or high chromium cast iron is integrally cast into a flat hammer which is easy to wear and damage, and has wide market prospect.
Description
Technical field
The utility model belongs to mine, building materials disintegrating apparatus accessory.
Background technology
The outer mine of state Inner, building materials impact breaker breaking ores all adopt potassium steel or rich chromium cast iron to cast whole bar at present, in use all exist not wear-resisting and beat disconnected Now to resemble, and particularly large-scale mine has restricted enterprise's production because of bar is not wear-resisting.
The utility model content
The purpose of this utility model is exactly to cast the not wear-resisting and cracky problem that whole bar exists at above-mentioned potassium steel that has adopted or rich chromium cast iron, design a kind of wear-resistant bar of founding impact breaker of new structure, replace the whole bar that adopts potassium steel, the casting of high ferrochrome.Thereby reach the desirable wear-resisting purpose of breaking ores bar.
Basic design of the present utility model is that the employing casting technology is toughness material carbon steel an one with high wear-resistant alloy material founding.In such scheme, the good carbon steel of impact flexibility performance as toughness district material, high wear-resistant alloy material as wear-resistant district material, under 1800-2000 ℃ liquation condition, realize liquid-solidly becoming whole bar, promptly obtain not only flexible but also the product of high-wearing feature is arranged in conjunction with founding.
Aforesaid high-wearing feature alloy material can be made up of high chromium tungsten or high-chromium material, also can be made up of other wear resistant alloy material.
Description of drawings
Fig. 1 represents the structure chart of the wear-resistant bar of founding impact breaker
Fig. 2 is the wear-resistant bar sectional drawing of founding impact breaker
Fig. 3 represents the wear-resistant bar process schematic representation of founding impact breaker
1-toughness material ZG230-450 foundry goods in the above legend, 2-high-wearing feature alloy material, 3-water mold, 4-founding molten bath.
The specific embodiment
Further specify below in conjunction with accompanying drawing:
The toughness material ZG230-450 (1) and the high chromium tungsten material 26CrW (2) of casting are assemblied in the water mold (3).Distribution forms (1800-2000 ℃) high temperature molten bath (4) then.High chromium tungsten material 26CrW:(2) is heated from molten, under the high temperature action of (1800-2000 ℃), the fusing infiltration of toughness material ZG230-450 (1) foundry goods top layer, fuse with high chromium tungsten material (2), form liquid-solid joint portion, thereby two kinds of material fusion one are formed the wear-resistant bar of founding impact breaker.
The toughness material ZG230-450 (1) and the high-chromium material Cr15Mo3 (2) of casting are assemblied in the water mold (3).Distribution forms (1800-2000 ℃) high temperature molten bath (4) then.High-chromium material Cr15Mo3 (2) is heated from molten, under the high temperature action of (1800-2000 ℃), the fusing infiltration of toughness material ZG230-450 (1) foundry goods top layer, fuse with high-chromium material (2), form liquid-solid joint portion, thereby two kinds of material fusion one are formed the wear-resistant bar of founding impact breaker.
The wear-resistant bar of the utility model founding impact breaker 1 district is toughness material spare (ZG230-450), and 2 districts are high chromium tungsten material (26Crw).
The mechanical performance table of comparisons 1
| Material | Tensile strength | Surrender | Rate elongation | Section is stretched | Impact (j) | | Remarks | |
| 1 district's carbon steel | 450 | 230 | 20 | 32 | ||||
| 2 district 26Crw | ?11-16 | HRC65 | Compound height is wear-resistant | |||||
| Rich chromium cast iron | ?3-5 | HRC50 | Disconnected easily | |||||
| Potassium steel | ?18 | HRC18 | HB229 is easy to wear |
Comparative illustration 1: the wear-resistant bar contrast of founding impact breaker high-manganese steel plate hammer wearability surpasses more than three times.
Comparative illustration 2: whole rich chromium cast iron is disconnected easily, and the wear-resistant bar of founding impact breaker can normal wear.
Economic benefit
The impact breaker installation of the outer mine of state Inner is used, and can bring into play the advantage of the wear-resistant bar material of founding impact breaker, has high impact toughness that high wear-resistant characteristic is arranged again.
One 1210 type impact breaker installation was changed once (every is overlapped four) in 30 days with potassium steel, and single-piece weighs 275 kilograms, and platform overlaps heavy 1100 kilograms, and annual one 1210 type impact breaker installation 12 times consumes 13200 kilograms of bars.
Economic benefit table 2
1210 type impact breakers
| Material | Annual change (inferior) | Material consumption (ton) | Unit price (unit/ton) | The amount of money (unit) | Remarks |
| High-manganese steel plate hammer | Change 12 | 13.2 | 12000 | 158400 | |
| The wear-resistant bar of founding | |
3.3 | 22000 | 72600 | Save 85800 yuan |
One the 1210 annual bar expense that can be bargh's saving 54% of type impact breaker installation contrast.Save and change accessory number of times 9 times, reduced working strength of workers, improved production efficiency and economic benefit.
State Inner mine, building materials have multiple impact breaker, year wear-resistant accessory of demand to estimate, and only year demand wear-resistant accessory in market, Hunan is pressed high manganese steel material and calculated 7200. ten thousand yuan in coin more than 6000 tons.If impact breaker all can be used the wear-resistant bar of founding impact breaker, by 50% saving, but only 6000 tons of mines of the wear-resistant accessory of market, Hunan year demand, building materials enterprise are saved 3,600 ten thousand yuan of RMB.
