S2, hardening media prepare：By mass percentage, 40%~50% and horse blood 50%~60% of water intaking, are filled Divide mixing for standby use；
S3, quenching：The earthing is wrapped up the blade of cutter blank, the blade of cutter blank is exposed, is then put into the cutter blank pre- It is warming up in 100 DEG C~120 DEG C of firing equipment, then, the firing equipment is with 4 DEG C per minute~5 DEG C of programming rate liter To 1100 DEG C~1150 DEG C, constant temperature is cooled down temperature during the hardening media is put into after 3~5 hours.
Preferably, the horse blood described in S1 and S2 is the blood of warm blood horse.
Preferably, the firing equipment is well formula glowing furnace.
Preferably, the earthing in S1, by mass percentage, by the clay 20%, borax 25%, iron powder 20%th, carbon dust 25% and horse blood 10% are sufficiently mixed composition.
Preferably, the earthing in S1, by mass percentage, by the clay 25%, borax 20%, iron powder 20%th, carbon dust 20% and horse blood 15% are sufficiently mixed composition.
Preferably, the earthing in S1, by mass percentage, by the clay 25%, borax 25%, iron powder 20%th, carbon dust 20% and horse blood 10% are sufficiently mixed composition.
Preferably, the hardening media in S2, it is by mass percentage, fully mixed by the water 50% and horse blood 50% It is combined into.
Preferably, in S3, before the cutter blank is put into the firing equipment, the firing equipment is warming up to 110 DEG C in advance.
Preferably, in S3, after the cutter blank is put into the firing equipment, the firing equipment is with 4 DEG C per minute of intensification Speed is warming up to 1130 DEG C.
Preferably, in S3, after the cutter blank is put into the firing equipment, and the perseverance after the completion of firing equipment intensification The warm time is 4 hours.
The beneficial effects of the invention are as follows：Present invention processing is simple and easy to apply, using the molysite and trace meter that are enriched in horse blood Element (blood of warm blood horse is containing molysite and minor metallic element compared with horn of plenty), by itself and the clay, borax, iron powder and carbon dust Precentagewise is blended together as earthing, carries out S3 treatment, the blade cooling that quickening that can be appropriate is wrapped up by the earthing, Also possesses hardness higher while ensureing that blade can possess stronger toughness, plasticity is high；And pressed in the hardening media Percentage is mixed into horse blood, using the molysite and minor metallic element that are enriched in horse blood, can also accelerate blade cooling, obtains blade Hardness higher is obtained, broken first ability is strengthened, and because blade hardness and toughness are high, can greatly extend Tang's knife entirety Service life.
