Abstract
The invention discloses a kind of pelletizing template tungsten-bast alloy, be made up of by weight percentage following composition: Cr? 0.1 ~ 1.5%, Ni? 3 ~ 9%, Co? 10 ~ 20%, Mo? 0.1 ~ 1.5%, C≤6%, W surplus; This tungsten-bast alloy has the advantages such as density is high, hardness is high, wear resistance is good, erosion resistance is strong, the good and cold and hot conversion of high thermal resistance is indeformable.
Description
Technical field
The present invention relates to alloy field, specifically provide a kind of pelletizing template tungsten-bast alloy.
Background technology
Pelletizing template is in the crucial that manufactures parts of high-temperature hot melt being carried out to granulation underwater, by template surface alloy and ceramic cutter high speed shear, realizes granulation.Therefore, the alloy making pelletizing template must have higher density, hardness, wear resistance, erosion resistance, high thermal resistance and the indeformable property of cold and hot conversion etc.At present, the external titanium carbide that uses makes pelletizing template, but there is hardness, intensity is low; The problems such as high-temperature soldering performance, wear resisting property difference, and the pelletizing template alloy of domestic use does not reach the job requirement of pelletizing template yet.
Therefore, research and develop a kind of alloy being applicable to pelletizing template, become people's problem demanding prompt solution.
Summary of the invention
Given this, the object of the invention is at least solve and make that the density that pelletizing template alloy exists is low, low, easy generations of difference of hardness, wear resistance is corroded and the problem such as distortion in the past.
Concrete technical scheme provided by the invention is: a kind of pelletizing template tungsten-bast alloy, is characterized in that, is made up of by weight percentage following composition: Cr0.1 ~ 1.5%, Ni3 ~ 9%, Co10 ~ 20%, Mo0.1 ~ 1.5%, C≤6%, W surplus.
Preferably, be made up of by weight percentage following composition: Cr0.2 ~ 1.0%, Ni5 ~ 7%, Co13 ~ 15%, Mo0.2 ~ 1.0%, C≤4.68%, W surplus.
Further preferably, be made up of by weight percentage following composition: Cr1.8%, Ni6%, Co14%, Mo0.8%, C2%, W surplus.
Further preferably, described composition C is diamond powder.
The making processes that pelletizing template tungsten-bast alloy provided by the invention carries out pelletizing template is: by above-mentioned moiety powder uniform stirring, and---cast is stirred, and---stripping forming---suppresses---vacuum high-temperature sintering---double-side rough grinding, again through series of programs such as mechanical workouts, final obtained pelletizing template finished product.
Pelletizing template tungsten-bast alloy provided by the invention, has the advantages such as density is high, hardness is high, wear resistance is good, erosion resistance is strong, the good and cold and hot conversion of high thermal resistance is indeformable.
Embodiment
Below with specific embodiment, the present invention is further expalined, but is not limited to the present invention.
Be used for making pelletizing template alloy to solve in the past, low, easy generations of density low, difference of hardness, wear resistance existed is corroded and the problem such as distortion, the invention provides a kind of pelletizing template tungsten-bast alloy, this tungsten-bast alloy is made up of by weight percentage following composition, Cr0.1 ~ 1.5%, Ni3 ~ 9%, Co10 ~ 20%, Mo0.1 ~ 1.5%, C≤6%, W surplus.
Wherein, this tungsten-bast alloy is when C element content is lower, add Cr element and can improve intensity and hardness, and hardening capacity is good, hard and wear-resisting, and Ni element has high strength, high tenacity, coordinates with chromium, has stainless, heat-resisting feature of not easily getting rusty, W, Mo element not only can put forward heavy alloyed high-temperature behavior simultaneously, prevent from heat treatment process, occurring overheated phenomenon, but also heat treated hardening capacity can be improved, reduce temper brittleness, make structure of steel fine and close, ensure intensity and the toughness of material.
Preferred moiety proportioning is by weight percentage: Cr0.2 ~ 1.0%, Ni5 ~ 7%, Co13 ~ 15%, Mo0.2 ~ 1.0%, C≤4.68%, W surplus; Highly preferredly be: Cr1.8%, Ni6%, Co14%, Mo0.8%, C2%, W surplus.
Wherein, when composition C selects diamond powder, the hardness of this tungsten-bast alloy and wear resistance all can be significantly improved, because we found through experiments, when Mo, W and a small amount of diamond powder carry out mixed smelting, diamond powder can increase substantially hardness and the wear resistance of Mo and W, and the performance of alloy is significantly improved.
Embodiment:
According to each moiety powder proportionally uniform stirring in the following example,---cast is stirred, and---stripping forming---suppresses---vacuum high-temperature sintering---double-side rough grinding, again through series of programs such as mechanical workouts, final obtained pelletizing template finished product, concrete proportioning is in table 1.
Table 1
Wherein, what in embodiment 1,2,4,5, C selected is common simple substance carbon, and what select in embodiment 3,6 is diamond powder.
The pelletizing template made according to above-described embodiment proportioning is carried out performance test, and concrete test chart, in table 2.
