Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a sensor and a control system. The control system can be configured to execute a heating process and determine a stage of the heating process based on sensor data from the sensor.

The present disclosure discloses a reflow oven, comprising a heating zone, a cooling zone, a barrier and exhaust zone, a gas exhaust passage, a gas exhaust power device, and a detection device. The heating zone comprises a heating zone inlet and a heating zone outlet. The cooling zone comprises a cooling zone inlet and a cooling zone outlet. The barrier and exhaust zone is located between the heating zone outlet and the cooling zone inlet. An inlet of the gas exhaust passage is communicated with the barrier and exhaust zone. The gas exhaust power device is disposed on the gas exhaust passage. The detection device is disposed on the gas exhaust passage and used for detecting parameters of gas in the gas exhaust passage, wherein the parameters of the gas reflect a blockage condition of the gas exhaust power device. The reflow oven according to the present disclosure can ensure that the gas containing soldering flux is sufficiently drawn out from the barrier and exhaust zone, thereby ensuring the production quality of a circuit board and improving the qualified rate of the circuit board.

The invention relates to a device for the hot-dip galvanizing of components, comprising a galvanizing tank for holding the zinc melt in a tank interior formed by a wall of the galvanizing tank, according to the invention a monitoring apparatus being provided for monitoring the wall thickness of the wall of the galvanizing tank during the galvanizing operation. The invention further relates to a corresponding method for hot-dip galvanizing.

The functional condition of an induction crucible furnace is checked by first establishing a set-point parameter corresponding to an optimum functional condition of the induction crucible furnace and characterizing the vibratory behavior of same. Then, during normal operation of the furnace, an actual-value parameter of the vibratory behavior is determined. These two parameters are then compared and, if a magnitude of a difference therebetween exceeds a threshold, an alarm is generated.
