摘要:
An induction heating device for a metal strip, the induction heating device including: an induction coil that is provided on one strip thickness direction side or on both strip thickness direction sides of a metal strip that travels along its length direction, and that induces an induction current in the metal strip when a primary current is passed through the induction coil, the induction current configuring a closed loop as viewed from the strip thickness direction of the metal strip; plural magnetic cores that face the metal strip in the strip thickness direction and that are disposed at a specific position separated from the metal strip by a specific distance so as to concentrate magnetic flux generated by the induction coil; and a moving mechanism that is coupled to the magnetic cores, and that moves the magnetic cores so as to increase or decrease a disposed number of the magnetic cores at the specific position disposed side-by-side along a strip width direction of the metal strip.
摘要:
The invention relates to a device for the controlled filling of a tap opening, which is provided in a metallurgical furnace, with a trickle-proof, fire-resistant mass, comprising a filling pipe having a lower opening (11) and an upper opening (10), a container for the filling mass, and a closing device, wherein the upper opening (10) is connected to the container by means of the closing device, which is interposed therebetween, in such a way that the the connection can be opened and closed by means of the closing device under control by means of a control device such that filling mass falls through the filling pipe as a result of the closing device being opened, wherein the filling pipe is designed as a telescopic pipe.

The multi-chamber heat treatment device includes a temperature sensor (31) attached to an object to be treated (X), a signal transmission unit (30) which transmits a detected signal from the temperature sensor to the outside of a heating chamber and a cooling chamber, and a temperature measuring unit (40) which is arranged outside the heating chamber and the cooling chamber to measure the temperature of the object from the detected signal of the temperature sensor transmitted from the signal transmission unit (30).
摘要:
There are provided a method for heat treatment, a heat treatment apparatus, and a heat treatment system capable of efficiently controlling heat treatment such as a bright treatment with high precision and without causing oxidation and decarbonization. Computation of ”G 0 (standard formation Gibbs energy) is performed by referring to sensor information from respective sensors, and an Ellingham diagram, a control range, and a status of the heat treatment furnace in operation expressed with ”G 0 are displayed on a display device 531, while a flow rate of hydrocarbon gas is controlled by a control unit 534 so that ”G 0 is within the control range.
