Disclosed is an apparatus and methods for sintering particulate to make a workpiece.

Disclosed is a continuous processing line for processing a non-magnetic metal strip 1 and specifically to an induction heating apparatus 14 and method intended for heating the non-magnetic metal strip travelling through the continuous processing line, including a coating section 20, the apparatus being installed downstream from the coating section in the direction of travel of the strip, the apparatus making it possible to raise the temperature of the strip across the entire width thereof to the level required to obtain the sought development of the coating thereof, the heating apparatus including at least one cross-flow inductor 15.

An induction heating method includes a step of supplying a ring-shaped member to a predetermined section serving as a heating target section using an induction coil, and a step of moving the ring-shaped member along a reference axis so as to pass through the predetermined section. The moving step includes controlling contact between the ring-shaped member and a different member by a contact control portion.

A method of heating direct reduced iron between a direct reduced iron source and processing equipment for the direct reduced iron, comprises providing a conduit heater assembly between the direct reduced iron source and the processing equipment, wherein the conduit heater assembly receives a flow of the direct reduced iron from the direct reduced iron source and heats the direct reduced iron as the direct reduced iron flows through the conduit heater assembly and to the processing equipment.

Systems and processes for external combustion air preheating for providing preheated combustion air to a furnace. The furnace systems convective heating section includes multiple heating coils for waste heat recovery. The heating coils may be used for preheating a feed (feed preheat coils), heating a boiler feed water, superheating steam, or heating or superheating a feed stream prior to the feed being fed to the radiant coil. The waste heat in the combustion gas is also used to heat a heat transfer fluid, which may be used to pre-heat combustion air or for other purposes within the plant.

Induction furnace, method for operating, control program, and control device for an inducation furnace for heating planar rolled stock material made of metal. The rolled stock passes through the induction furnace in a longitudinal direction and extends transversely thereto from a first to a second rolled stock edge. The induction furnace has a plurality of module pairs which, viewed in the longitudinal direction, follow one another sequentially and each have a first and a second induction module. The induction modules, as viewed in the transverse direction, are positioned at a respective initial position, so that the first induction modules are arranged offset towards the first rolled stock edge and the second induction modules are arranged offset towards the second rolled stock edge. Induction modules are supplied with electrical power via respective power supply devices. A respective electrical target variable is defined for each induction module.
