Description
Technical field：
The present invention relates to a kind of reinforcement process of grinder hammerhead, more particularly to a kind of reinforcement process of potassium steel tup.
Background technology：
Domestic grinder hammerhead is most of at present uses potassium steel material, and not enough, service life is very short for its wearability.It is broken
The tup of lime stone typically can be used 60 1 90d, under some specific conditions, use less than 7d.Simultaneously because tup is in work
In suffered impulsive force and less, make the drawing hardening effect of potassium steel tup not notable, its antiscour wear resistance is poor.Gao Meng
Steel will could produce the cementation zone of high rigidity in the case of big impulsive force, and not wear-resisting in the case that impulsive force is small；
Also medium managese steel tup, more durable in the case where impulsive force is less big because it has hardness and toughness higher, and is magnetic；
Rich chromium cast iron tup has excellent wearability, but toughness is poor, and brittle fracture easily occurs.Alloy-layer in Double-metal composite hammer
Hardness is high and flexible, long service life, but manufacturing process are complicated, high cost.Therefore the hardness of tup is improved, its can be improved resistance to
Mill property, so as to mitigate brinelling;The toughness for improving material helps the generation and extension for suppressing crackle, is conducive to mitigation to wash away mill
Damage.
The content of the invention：
It is an object of the invention to provide a kind of process is simple, the hardness of potassium steel tup and the potassium steel tup of wearability can be improved
Reinforcement process.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of reinforcement process of potassium steel tup, comprises the following steps：
1）It is configured to high-strength abrasion-proof powder material：Chromium powder and graphite powder are pressed 1：2 ratio is well mixed, and is configured to high intensity
Abrasion-resistant powder materials for later use；
2）Cladding wearing layer：The surface of potassium steel tup is heated up to bulk material fusing point, then one layer is uniformly sprayed on surface
High-strength abrasion-proof powder material, makes the wear-resisting powder material of floor height intensity of Surface coating one of potassium steel tup, permanent 60-120 minutes, makes height
Chromium powder in the wear-resisting powder material of intensity chemically reacts at high temperature with graphite powder；
3）Forging tup：By the potassium steel tup for being coated with wearing layer in step 2, potassium steel tup is applied using metal forming machinery
Plus-pressure, is forged；
4）Cooling tup：By the potassium steel tup after forging, it is cooled to normal temperature and gets product.
The step 2）-4）Carry out under vacuum conditions.
The beneficial effects of the present invention are：Process is simple of the invention, low cost of manufacture can improve potassium steel tup
Hardness and wearability, extend the service life of potassium steel tup.
Specific embodiment
Embodiment 1
1）It is configured to high-strength abrasion-proof powder material：Chromium powder and graphite powder are pressed 1：2 ratio is well mixed, and is configured to high intensity
Abrasion-resistant powder materials for later use.
2）Cladding wearing layer：The surface of potassium steel tup is heated up to bulk material fusing point, is then uniformly sprayed on surface
The one wear-resisting powder material of floor height intensity, makes the wear-resisting powder material of floor height intensity of Surface coating one of potassium steel tup, permanent 80 minutes.It is high-strength
The chromium powder spent in wear-resisting powder material chemically reacts at high temperature with graphite powder, and part chromium produces chromium carbide with graphite reaction,
Make tup that there is high impact-resistance, high-wearing feature and highly corrosion resistant ability；Part graphite is transformed into diamond lattic structure
Carbon atom, improves tup hardness；Responseless chromium is mixed into lattice potassium steel high with potassium steel, tup is had high impact-resistant
Ability, high-wearing feature and highly corrosion resistant ability.
3）Forging tup：By the potassium steel tup for being coated with wearing layer in step 2, potassium steel is hammered into shape using metal forming machinery
Head applies pressure, is forged.Wearing layer can be made finer and close with what potassium steel tup surface was combined, optimize microstructure knot
Structure, further increases the intensity of potassium steel tup.
4）Cooling tup：By the potassium steel tup after forging, it is cooled to normal temperature and gets product.
The step 2）-4）Carry out under vacuum conditions, prevent chromium to be oxidized with graphite.
Bigger than the potassium steel tup hardness without working process through the potassium steel tup obtained by the present invention, wearability is more
By force, service life is longer.In broken lime stone, the potassium steel tup without working process typically can be used 60 1 90d, through this
The obtained potassium steel tup of invention typically can be used 200 1 300d in broken lime stone.
General principle of the invention, principal character and advantages of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited to the above embodiments, simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.
