Conclusions
-
1.
Band saws of steel V2F can be heat treated by means of flame hardening and combined heating (high-frequency induction and gas burner).
-
2.
Under optimal conditions the heat treatment ensures hardening of the teeth to HRC 62-65 to a distance of 0.5–0.8 mm from the tip of the teeth, the hardness of the valleys not exceeding HRC 45.
-
3.
The productivity of hardening with combined heating is five to six times that of standard flame hardening.
-
4.
The durability of band saws in cutting ferrous metals is 6–12 h (or 0.6–2.0 m2 of sawed material), which is three to five times the durability of saws made of steel U10A.
