After following test method have studied removal of impurities and forge the influence of number of times and speed to hot composite cutter performance.
（1）Influence of the removal of impurities to polymerizing power and surface property
On the premise of raw material are certain, the impurity removed in steel is more, and the performance for being molded later is better, and this is many institutes
Known.And in steel, there are most impurity is exactly organic impurities, metal impurities and absorption oxygen and steam, tradition
Removing method of the physics impurity elimination processing mode for impurity than more conservative, it is difficult to thoroughly remove steel in impurity, it is impossible to reach
To technological requirement, frequently result in processability and do not reach technological requirement.
Steel are processed with sodium hydroxide solution at normal temperatures first, organic impurities therein is removed；Then perchloric acid is boiled to go
Except the organic impurities such as graphite or metal mineralizer；Finally boil removing metal and its oxidation in a heated condition with hydrochloric acid
Thing, and neutrality is washed to distillation, the hot environment being used in combination in intermediate frequency furnace heats 1400-1600 DEG C, maintains temperature 2-4h,
Dirt, absorption oxygen and the steam on its surface etc. are removed while melting, makes steel grain surface very clean.
（2）Forge influence of the number of times to hot composite cutter performance（As shown in Figure 1）
Influence of the number of times forged after heat treatment to the hardness and toughness of steel is very big, it can be seen that initial strip
Under part, hardness is than relatively low, and toughness is stronger, but with the increase of number of times is forged, hardness is gradually reduced after a high level is reached,
Finally tend towards stability, and toughness starts to tend towards stability just, with the increase toughness dramatic decrease for forging number of times, this be due to
The distance between the increase for beaing number of times, steel particle and free path all in reduction, and with the reduction of distance and free path,
Density is gradually increasing, and causes hardness gradually to become strong, degraded toughness, and fragility becomes strong, and increases with the constantly upper of number of times is forged, crisp
Property be continuously increased, cause the hardness of steel also to decline therewith, but the scope for declining is certain, finally because spacing is permanent
Fixed, hardness and toughness all tend towards stability.
（3）Forge influence of the speed to hot composite cutter performance（As shown in Figure 2）
It can be seen that as the increase for forging speed, hardness are gradually reduced after a high level is reached, finally tending to flat
Slow, and toughness is then always slowly rising, this is the distance between steel particle and freely due to the increase for beaing speed
Journey, due to forging the quickening of speed, generates the overlapping crystal of a large amount of high intensity all in reduction during this, and with forging
The amount for beating speed increase generation crystal also increases, and this overlapping crystal plays booster action to the toughness of steel, causes hardness
Gradually become strong, toughness improves, and increases with the constantly upper of speed is forged, and toughness is continuously increased.
Based on above-mentioned, it is an advantage of the current invention that the present invention is with steel as base stock, removal of impurities is strictly gone by pre-processing removal of impurities
Matter, can greatly improve the polymerizing power of steel, prevent outer surface from occurring being stained vestige and sintering bubble, forge split it is horizontal etc.,
High intensity is carried out after slow annealing shaping forges shaping, polishing grinding after quantitative cutting, and preparing can be big with hardness, and toughness is strong
Cutter, and simple production process, production efficiency greatly improved, and repeatability is strong, convenient production process operation, into
This lower accuracy is high, environmental protection and energy saving, with excellent physical property
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Any modification, equivalent and improvement for being made within principle etc., should be included within the scope of the present invention.
