The present invention relates to a device for carrying component parts to be temperature-controlled, in particular coiled metal strips or metal wires, in a temperature-control device. The carrier device has a base body and a carrier element, to which a component part is attachable, wherein the carrier element is detachably attached to the base body. The base body has a transport coupling, which is configured such that the transport coupling is detachably fixable to a handling system for handling the device.

A heating furnace for heating an annular component, includes a furnace body, a heat medium driving component, a support part, a guide component, and a hollow cylinder. Part of the heat medium is ejected to the outer circumferential surface of the annular component through the guide part, and part of the heat medium flows through the inner channel of the hollow cylinder, and be ejected to the inner circumferential surface of the bearing via the second heat medium channel arranged on the hollow cylinder to heat the inner circumferential surface of the bearing. In this way, the hollow cylinder plays a role of distributing the gas to some extent, and as the upper end of the hollow cylinder is a sealed structure, the flowing gas is all converted into effective heat exchange gas flow and restricted to a heat exchange space on the bearing surface.

The invention relates to a method for heating a furnace, wherein the furnace comprises an inner chamber and a outer chamber. A process gas is introduced into the inner chamber. A fuel is combusted with an oxidant to produce combustion gases in a combustion chamber. The combustion gases are passed through the outer chamber, and recirculated to the combustion chamber. The process gas is pre-heated by indirect heat exchange with the combustion gases.
