Embodiment Construction
[0019] like figure 1 As shown in the figure, the trolley-type resistance furnace includes a trolley 1 and a furnace body 2. The furnace lining of the furnace body 2 is made of all-aluminosilicate refractory fiber 1260 needle-punched blanket (Shanghai Morgan, American technology) with excellent thermal insulation performance. After special construction, it is combined into a full fiber lining. The temperature resistance grade of refractory fiber is less than or equal to 1350℃. The inner surface of the fiber is artificially polished, and the surface is smooth to improve its heat radiation efficiency.
[0020] The furnace lining adopts a full-fiber refractory module structure, which is very convenient for maintenance. If it is damaged due to mechanical collision, it can be used as long as it is repaired locally. This kind of furnace lining also has the characteristics of easy installation and short construction time. The full-fiber furnace lining is hung on the steel frame, wh...

Abstract
The invention discloses a bogie-hearth resistance furnace. The bogie-hearth resistance furnace comprises a bogie and a furnace body. The bogie comprises a frame and a wheel device. The frame is composed of cross beams and longitudinal beams, wherein the cross beams and the longitudinal beams are connected through joist steel. The wheel device is located on the lower sides of the longitudinal beams. A thermal-insulating layer is arranged on the upper end faces of the cross beams. A load-bearing fire-proof layer is further laid on the thermal-insulating layer. The load-bearing fire-proof layer is made from high-alumina bricks. Electric heating elements are distributed below the load-bearing fire-proof layer. When the bogie-hearth resistance furnace works, electric heating elements on the furnace body and the electric heating elements below the load-bearing fire-proof layer are switched on at the same time, and therefore temperature balance of all angles, including the bottom, of a processed workpiece can be guaranteed. By the adoption of the technical scheme, the bogie-hearth resistance furnace is a novel bogie-hearth resistance furnace which is high in product percent of pass, good in usage effect, and convenient to operate.
Description
technical field [0001] The invention relates to the field of industrial furnace preparation, in particular to a trolley-type resistance furnace capable of maintaining uniform temperature of heated workpieces in the furnace. Background technique [0002] Industrial furnace is mainly composed of furnace body (including furnace lining), heating device, hot air circulation device, trolley, trolley transmission device, furnace door, heat dissipation device, sealing device, temperature control and recording system, power system and other main parts. The furnace lining in the furnace body is mostly made of all-aluminum silicate refractory fiber cotton with excellent thermal insulation properties. [0003] The trolley is one of the important parts of the industrial furnace, which undertakes the functions of heating and transferring the workpiece. The trolley type resistance furnace is a national standard energy-saving periodic operation furnace. It has an ultra-energy-saving struct...
