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 Ac.sub.3 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.

The present disclosure related to an electric grill's housing, controller, and a mounting bracket which mounts the controller to the housing. The mounting bracket is generally hollow and forms a thermal barrier between the controller and the housing, wherein the thermal barrier protects the controller from heat generated in the housing. As a result, the controller does not require insulation and may include lower temperature rated components. Moreover, the mounting bracket may have metallic tabs which interface with spring elements on the controller, thereby fastening the controller to the bracket. These spring elements and metallic tabs may be in electric communication with the housing, thereby allowing the controller to act as an electric ground with respect to the housing.

A heater assembly includes a heating member, a mounting member that mounts the heating member to a wall of an external component, and an insulator disposed between the heating member and the wall. The insulator electrically insulates the heating member from the wall and blocks a ground path from the heating member to the wall of the external component.

The present application provides a fixing apparatus for a furnace wire of a furnace body heater, which is formed by assembling a plurality of fixing units. A structure of each of the fixing units includes: a front end structure and a tail end structure connected together. The front end structure is provided with a first recess and a second recess. The tail end structure is provided with a third recess and a fourth protrusion block. Two adjacent ones of the fixing units form a first splice structure, in the first splice structure, the fourth protrusion block of the fixing unit at the top is snap fitted in the third recess of the fixing unit at the bottom to achieve fixation. An opening of a first recess of the fixing unit at the bottom and an opening of a second recess of the fixing unit at the top are butt-jointed together.

Systems, devices, and methods for continuously cooling a rotary shaft seal of a pressure vessel (e.g., of a furnace) are provided. A continuous flow of gas into the pressure vessel can be utilized to continuously cool the rotary shaft seal as the gas enters the pressure vessel. The rotary shaft can have a turbine wheel attached to it. The turbine wheel, when powered, can mechanically increase the natural convective gas flow inside a baffle tube of the furnace, effectively lengthening the usable, working homogenous zone of the furnace making overpressure heat treatment (OPHT) possible for longer canted cosine theta (CCT) magnets and Race Track coils.
