IOB engineers and builds heat treatment furnaces type walking beam furnace in various executions.

For the treatment of special billets, square, round or cylindrical.

The charging of the parts will be done using a roller conveyor which is arranged inside the furnace or using a loading table in front of the furnace by which the movable hearth moves like a fork into the loading table and hence transports the parts into the furnace.

The charging can be done in a single row or mutiple rows depending of the length of the parts.

The basic walking beam system consists out of a lifting and drive frame which work independent from each other. During the lift movement the lift frame will be lifted or lowered by means of rollers and an increasing slope beam. The movement forward and backward will be executed by the drive frame with rollers. The advantage of this system compared to the system with the eccentric drive is the variable pitch distance of the walking beam system.

The sealing between the stationary and movement hearth is done using a water sealing unit.

The to the movement hearth connected sealing swords submerse in each position of the lifting frame into the water and hence seal off the furnace area

According to the material charged the construction and the amounts of stationary and movement hearths are determined .

The heating equipment with its burner amount and central recuperator system is adjusted to the respective furnace capacity

The measuring and control plant controls the temperature requirements and also the material sequence through the furnace.

Unloading of the billets at the furnace end will be done trough a respective chute inside the furnace onto the roller conveyor for further transport to the press.
