摘要： Provided is a far-infrared radiation multi-stage type heating furnace for steel sheets for hot stamping, the furnace including far-infrared radiation heaters having flexibility that are prevented from deflecting even during heating at temperatures ranging from the Ac3 transformation temperature to 950° C. The far-infrared radiation multi-stage type heating furnace includes: multiple-staged heating units that accommodate steel sheets for hot stamping, each heating unit formed by thermal insulation materials disposed around the periphery; and far-infrared radiation heaters positioned above and below the heating units. A far-infrared radiation heater (14-1) is received by a plurality of first metal strips (26) so as to be disposed approximately horizontally. The plurality of first metal strips (26) are disposed so that their strong axis direction approximately corresponds to the direction of gravity and supported by support pieces (27) so as to be expandable and contractible in a longitudinal direction by thermal expansion or thermal contraction. The support pieces (27) are disposed outside the thermal insulation materials in the heating units and a ceiling unit.

摘要： An object of the present invention is to stably support steel sheets for hot stamping accommodated in a far-infrared radiation multi-stage type heating furnace over a long period of time using steel sheet support members having a small projected area and inhibited from thermally deforming. The far-infrared radiation multi-stage type heating furnace of the present invention includes: heating units and a ceiling unit arranged in a vertical direction with multiple stages to accommodate steel sheets for hot stamping that are aluminum-coated steel sheets or zinc-coated steel sheets; and far-infrared radiation heaters disposed within the heating units and the ceiling unit to heat the steel sheets for hot stamping to a temperature ranging from the Ac3 transformation temperature to 950° C. Steel sheet support members are mounted to the heating units to support the steel sheets for hot stamping by point contact or line contact with the steel sheets for hot stamping. The steel sheet support members are supported so as to be expandable and contractible in a longitudinal direction by thermal expansion or thermal contraction.

摘要： The present invention provides a far-infrared radiation heating furnace for steel sheets for hot stamping configured to inhibit thermal deformation of the furnace body and furnace body parts. A far-infrared radiation heating furnace (10) includes heating units (13-1) to (13-6), a ceiling unit (19), and a furnace body frame (12) made of steel, the heating units including: blocks made of a thermal insulation material, the blocks being disposed around horizontal planes of spaces for accommodating the steel sheets for hot stamping; and far-infrared radiation heaters positioned above and below the steel sheets for hot stamping to heat the steel sheets for hot stamping, the furnace body frame being disposed around the heating units and the ceiling unit. The furnace body frame includes spacers (17-1) to (17-7) that space the heating units and the ceiling unit apart from the furnace body frame and support them.
