Abstract
The present invention provides a kind of quenching technical of 45# round steel crawler belt axis pin of size in ￠ 36 to ￠ 45, is related to a kind of metallurgical steel quenching technology field.The present invention comprises the following steps：First, the applicable inductor mid-frequency induction hardening of track pin；Then, 200 DEG C of lonneals in electrical kiln.The present invention need to only quench and tempering is fully achieved that former quenching technical requirement performance is constant, and surface HRC reaches 45 50, and workpiece centre hardness HB reaches 240 270, using for many years from occurring without axis pin phenomenon of rupture.
Description
Technical field
The present invention relates to a kind of metallurgical steel quenching technology field, more particularly to a kind of size ￠'s 36 to ￠ 45
The quenching technical of 45# round steel crawler belt axis pins.
Background technology
The quenched tempering of original production process, Q-tempering process are more, of high cost.
The content of the invention
Shortcoming present in regarding to the issue above, the present invention provide a kind of 45# round steel of size in ￠ 36 to ￠ 45
The quenching technical of crawler belt axis pin, makes that its quenching technical process is few, cost is low, and quenching property is reliable and stable, and new process is quenched over 5 years
Track pin axle fracture phenomenon never occurred for the workpiece of fire, and good economic benefit is brought for quenching.
To solve the above-mentioned problems, the present invention provides a kind of quenching for 45# round steel crawler belt axis pin of size in ￠ 36 to ￠ 45
Ignition technique, wherein, comprise the following steps：
S10, first, track pin is with being applicable in inductor mid-frequency induction hardening；
S20, then, 200 DEG C of lonneals in electrical kiln.
Preferably, by mid-frequency induction hardening and electrical kiln lonneal twice technique, workpiece core hardness is made to reach 240-
270HB, case hardness reach 45-50HRC.
Compared with prior art, the present invention has the following advantages：
The quenching technical process of our company is few, cost is low, and quenching property is reliable and stable, the workpiece that new process quenches over 5 years
Never track pin axle fracture phenomenon occurred, good economic benefit is brought for quenching.
