The method for heating a metal component to a target temperature, in which the component has a preliminary coating and is passed through a furnace that has at least four zones, which can be respectively adjusted to an individual zone temperature, wherein the component is passed successively through at least an initial heating zone, a plateau zone, a peak heating zone and an end zone and wherein the initial heating zone is adjusted to an initial heating temperature, the plateau zone is adjusted to a plateau temperature, the peak heating zone is adjusted to a peak temperature and the end zone is adjusted to the target temperature, the plateau temperature being chosen such that the temperature of the component in the plateau zone lies in a band around a melting temperature of the preliminary coating which is characterized in that the peak temperature lies by at least 100 K above the target temperature.

A system and method is disclosed for monitoring graphite electrodes for use in an electric arc furnace includes receiving an electrode identifiers from a radio frequency identification (RFID) tag reader configured to interrogate RFID tags in the vicinity of an electric arc furnace (EAF), wherein the RFID tags are attached to electrodes. The electrode identifier is associated with EAF data collected from the EAF and the association is stored in a memory. The association is used for generating current and past operating parameters of the electric arc furnace for specific electrodes. Data for each specific electrode used in the EAF can also be collected for determining performance parameters for specific electrodes.

A multi-pane door assembly for an oven appliance includes a door having first and second door panes. The first door pane is secured to the second door pane at a hinge point and is rotatable with respect to the second door pane between open and closed positions. As such, the door panes define a space therebetween when the first door pane is in the closed position. The door assembly also includes an engagement device for securing the door panes together, a locking mechanism for locking the engagement device, and a controller communicatively coupled to the actuating device. The locking mechanism includes, at least, a locking member and an actuating device. Thus, the controller is configured to receive one or more safety conditions relating to the oven appliance and select whether to engage or disengage the actuating device based on whether the safety condition(s) correspond to the predetermined safety condition(s).

A process control device is connected to the temperature sensing device and to the power control device for controlling the power control device. The process control device comprises a current control device with which, in particular in the absence of a measuring signal of the temperature detection device, the power control device can be controlled.

The present invention describes an improved process for the commercial scale production of high-quality catalyst materials. These improved processes allow for production of catalysts that have very consistent batch to batch property and performance variations. In addition these improved processes allow for minimal production losses (by dramatically reducing the production of fines or small materials as part of the production process). The improved process involves multiple steps and uses calcining ovens that allow for precisely control temperature increases where the catalyst is homogenously heated. The calcining gas is released into a separate heating chamber, which contains the recirculation fan and the heat source. Catalysts that may be produced using this improved process include but are not limited to catlaysts that promote CO hydrogenation, reforming catalysts, Fischer Tropsch Catalysts, Greyrock GreyCat™ catalysts, catalysts that homologate methanol, catalysts that promote hydrogenation of carbon compounds, and other catalysts used in industry.

In an example implementation, a method of operating a sintering furnace includes receiving information about a green object load to be sintered in a sintering furnace, determining a sintering profile based on the information, and performing a sintering process according to the sintering profile. During the sintering process, a sensor reading that indicates a degree of densification of a green object in the load is accessed from a densification sensor. The method includes initiating a cool down phase of the sintering process if the sensor reading has reached a target sensor reading.
