Product Name: IF hardening furnace

Typical Application:

Applicable to IF hardening of 45#,40Cr, 42CrMo, 65Mn. Current applications include IF hardening for round bar, piston rod, grinding rod, sucker rod, anchor bolt,blade, steel wire.

If induction hardening

IF hardening technique (limited to certain high strength alloy steels) that reduces the residual internal stresses and distortion resulting from non-uniform transformation and thermal shock typical of conventional oil quenching.

Advantages of IF hardening furnace

● High reliability:Adopt famous brand components of IGBT power supply which reduce fault rate and make sure the equipment can run reliably.
●  Safe and reliable. There are reliable protection covers for the mechanical rotating parts,which is durable and very safe for operators. Automatic protections for water temperature, water pressure,phase shortage, overcurrent and undervoltage.
●  Easy installation & commission and simple operation.
●  Transmission mechanism frame has sufficient strength and rigidity for ease of installation of equipment
●  Feeding and discharging table is using high quality steel welded firmly, which can withstand a certain impact load.

High automation of IF hardening furnace

●  If hardening furnace feeding system: roller table + power press roller, each shaft driven by independent motor reducer, independent frequency converter control; flexible design of speed difference output, sectional control of operating speed.
●  Roller electrical isolation: Aiming at the problem of spark between workpiece and roller, we designed a strong and durable electrical isolation system for roller, which completely solved the problem of lightening damage of workpiece.
●  The industrial computer system: Real-time display of the working parameters, workpiece parameters memory, storage. printing, fault display, alarm and so on.
●  Formula Management Function: Powerful Formula Management System. After selecting the parameters of steel grade to be produced, relevant parameters can be automatically invoked without manual recording, consulting and inputting the parameters required for various workpieces.
● Full computer control is implemented. All the process parameters are stored in PLC. The operator can start the steel bar quenching furnace by adjusting the corresponding process parameters.
