Auxiliary-heating uniform-heating high-temperature-heating-furnace inner cavity for induction heating of metal sheet band

Abstract

The invention relates to an auxiliary-heating uniform-heating high-temperature-heating-furnace inner cavity for induction heating of a metal sheet band. The auxiliary-heating uniform-heating high-temperature-heating-furnace inner cavity for induction heating of the metal sheet band comprises a strip-shaped upper silicon carbide beam group, a strip-shaped lower silicon carbide beam group and two refractory side plates. The upper silicon carbide beam group and the lower silicon carbide beam group are vertically spaced and are parallel. The two refractory side plates are arranged on the two sides of the upper silicon carbide beam group and the lower silicon carbide beam group in a sealed manner correspondingly. The upper silicon carbide beam group, the lower silicon carbide beam group and the two refractory side plates define the uniform heating inner cavity. The auxiliary-heating uniform-heating high-temperature-heating-furnace inner cavity for induction heating of the metal sheet band has the advantages the structure is simple, use is convenient, the atmosphere temperature of an electromagnetic induction heating furnace can be rapidly homogenized through the upper silicon carbide beam group and the lower silicon carbide beam group, an electromagnetic induction heating system can more accurately control the temperature, the metal sheet band is evenly heated when passing through the uniform-heating inner cavity, the metal sheet band is protected against a buckling phenomenon, and the product quality is improved.

Description

technical field [0001] The invention relates to a continuous annealing technology for thin metal strips, in particular to an inner cavity of a high-temperature heating furnace for auxiliary heat soaking and induction heating of thin metal strips. Background technique [0002] At present, the continuous annealing of thin metal strips is mostly carried out in high-temperature heating furnaces. In existing high-temperature heating furnaces, when the inner cavity is heated, the heat distribution is uneven, which leads to the phenomenon of buckling when the thin metal strips pass through the inner cavity for annealing. , leading to possible defects in the quality of the metal sheet, especially when using an induction heating furnace for high-temperature annealing, due to the electromagnetic induction technology involved, the requirements for product quality are relatively high. If the temperature in the atmosphere furnace is uneven, it is easy to cause the metal sheet The phenome...
