Problems solved by technology

The biggest disadvantage of this solution is that the heat insulation steel plate in the innermost layer not only increases the weight of the trolley, but also makes its working conditions worse because it cannot dissipate heat outward, and its own temperature will accumulate and rise, eventually causing the heat insulation plate Deformation, cracking or even desulfurization, making its thermal insulation protection effect invalid
Therefore, this technical solution cannot be adopted in actual production

Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] Such as figure 1 As shown, the sintering machine trolley of the present invention includes a trolley body 1 and trolley baffles 2 arranged on both sides of the trolley body, and the inner surface of the trolley baffle 2 is coated with heat-insulating Coating 3, the surface of the heat-insulating coating 3 is coated with a wear-resistant and anti-corrosion coating 4 .

[0016] The thermal insulation coating 3 and the wear-resistant and anti-corrosion coating 4 are sprayed by plasma spraying. The spraying of the thermal insulation coating 3 and the wear-resistant and anti-corrosion coating 4 can be carried out in a thermal spraying workshop. The implementation process is carried out according to the thermal spraying processing flow and technical requirements. The inner surface (inner wall) of the trolley baffle 2 needs to be pre-treated b...

Abstract

The invention discloses a sintering pallet. The sintering pallet comprises a pallet body and pallet baffles arranged on two sides of the pallet body, wherein the inner surfaces of the pallet baffles are coated with thermal insulation coatings, and the surfaces of the thermal insulation coatings are coated with wear-resistant anti-corrosive coatings. According to the sintering pallet, the thermal dissipation of the trolley can be reduced, the energy is saved, and meanwhile the sintering yield is improved.

Description

technical field [0001] The invention relates to a sintering machine trolley, in particular to a sintering machine trolley with heat insulation function. Background technique [0002] At present, most iron ore sintering adopts the belt-type ventilation sintering process, and the sintering machine trolley is its main operation unit. The mixture composed of iron ore raw materials, fuel, flux and other auxiliary materials completes the high-temperature sintering process in the sintering machine trolley. Modern large-scale sintering machines have large scale and long production lines, and the trolleys are not only huge in size but also numerous in number (nearly 200 knots). In addition, the production organization mode of the belt sintering process is a continuous production mode, and the sintering trolleys are always in continuous periodic cycle operation during production, and it is difficult to carry out effective heat insulation treatment for them. The trolleys are all expo...
