Problems solved by technology

The traditional trolley includes a loading platform and several layers of insulation bricks are laid on the loading platform. These insulation bricks support the product on the one hand and protect the loading platform on the other. This structural design makes the trolley too heavy and the bricks used can Absorb a lot of heat, causing part of the heat generated by the resistance furnace to be absorbed by the insulation bricks, but this part of meaningless heat consumes a lot of electric energy and increases the production cost

Embodiment 1

[0015] like Figure 1~2 The resistance furnace energy-saving trolley shown includes a bearing platform 1, on which a layer of No. 1 insulation brick 2 is laid, and the No. 1 insulation brick 2 is laid to form a rectangle; No. 2 thermal insulation brick 3 and thermal insulation asbestos 4, the No. 2 thermal insulation brick 3 is laid into a shape with several cavities in the middle, and the cavity is filled with thermal insulation asbestos 4, No. 2 thermal insulation brick 3 and thermal insulation asbestos 4 are laid in the shape It is also rectangular; the area of ​​the rectangle formed by the No. 1 thermal insulation brick 2 is larger than the rectangle formed by the No. 2 thermal insulation brick 3 and thermal insulation asbestos 4, and the rectangle formed by the No. The rectangular projection formed by the insulation brick 2 is covered by the rectangle formed by the No. 1 insulation brick 2 .

Abstract

The invention discloses an energy-saving type trolley for a resistance furnace. The energy-saving type trolley comprises a bearing table, and is characterized in that a layer of thermal insulation bricks I are paved on the bearing table; thermal insulation bricks II and thermal-insulation asbestos are paved above the thermal insulation bricks I; the thermal insulation bricks II are into a shape with a plurality of cavities in middle; and thermal-insulation asbestos are filled in the cavities. Compared with the prior art, the energy-saving type trolley has the advantages that a bearing region on the bearing table of the trolley is still built by the thermal insulation bricks, and the non-bearing region is filled with thermal insulation asbestos, so that bearing requirements are met, energy-saving and consumption-reducing effect is achieved, and therefore, energy can be expected to be saved by 20% or more.

Description

technical field [0001] The invention relates to the technical field of roll heat treatment, in particular to an energy-saving resistance furnace trolley. Background technique [0002] The resistance furnace is an industrial furnace that uses electric current to heat the electric heating element or heating medium in the furnace, thereby heating the workpiece or material. It is a heating furnace that uses electric current to generate heat through resistive materials. Resistance furnaces are used in the machinery industry for heating before metal forging, metal heat treatment, brazing, powder metallurgy sintering, glass ceramics firing and annealing, melting of low melting point metals, drying of sand molds and paint films, etc. [0003] When the medium and large resistance furnace is working, the product to be heated is placed on the trolley outside the resistance furnace, and then the trolley is pushed into the resistance furnace for heating. The traditional trolley include...
