Abstract
The utility model discloses a thermal isolation casing for conveying glowing steel ingot which is a rectangular solid made of steel plates. The thermal isolation casing comprises an upper casing, a lower box, and a base. The utility model is suitable for mold released glowing steel ingot after the loading steel plants cast the steel. One layer of the heat insulation material is stoke on the inner wall of the steel plate of the thermal isolation shell body. The inner surface of the heat insulation material is provided with one layer of steel plate to serve as a heat screen. Long directed two sides of the lower box are provided with rake slag holes along the long direction. The upper surface of the base is covered with blocky serpentines.
Description
The utility model is the stay-warm case that is used to transport red-hot steel ingot.
Steel mill waters the red-hot steel ingot of the demoulding behind the steel and is transported to the rough rolling mill and packs in the process of soaking pit, and heat loses in a large number, and the heat time heating time of causing steel ingot to pack into behind the soaking pit is long, influences the burning output of steel of soaking pit, and fuel consumption is big, and the steel ingot amount of oxidation loss is big.
For the temperature of the steel ingot that improves the soaking pit of packing into, the steel ingot steel ingot stay-warm case of packing into after casting, the demoulding is transported to rough rolling mill's soaking pit of packing into, can improve the temperature that steel ingot is gone into soaking pit significantly, improve the production capacity of soaking pit, reduce the steel ingot scaling loss, reduce and burn the steel unit consumption.
Stay-warm case of the present utility model is a cuboid, is skeleton with shaped steel, is welded into by steel plate, and stay-warm case is made up of last cover, nowel and base.On the cover body inner surface of steel plate, adhere to one deck by heat-barrier material (as asbestos, mineral wool, refractory fibre etc.) heat insulation layer of Xing Chenging, the inner surface of heat insulation layer is that a layer thickness is the insulation board of being made by metallic plate of 1-20mm, the suspension ring that hang on cover usefulness are together established in last cover outer surface of cupular part center, one side of nowel length direction is provided with three rake cinder holes along its length equably near base position, the another side is provided with four rake cinder holes equably, nowel is connected with bolt with base, build with refractory brick and insulating brick on the bottom surface of base, the refractory brick upper berth is with the serpentine of bulk.
36 substances of steel mill one heat steel liquid casting are erectly to pack into immediately after 8.2 tons the steel ingot demoulding in the stay-warm case, steel ingot carries out soaking, surface temperature begins to rise, steel ingot is transported to the soaking pit shove charge, and shorten its heat time heating time at soaking pit, improves soaking pit production capacity 50%, reduce the scaling loss of steel ingot in stove more than 0.5%, reduce soaking furnace steel-smelting unit consumption 60%, thereby reduced the production cost of rough rolling mill's steel billet, and improved the recovery rate of rough rolling mill's steel billet.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
The steel ingot stay-warm case is a cuboid, and cover body is welded into by steel plate, and by last cover 1, nowel 2 and base 3 are formed.All glue with refractory fibre 8 as heat insulation layer cover body steel plate inboard, heat insulation layer thickness is 150-300mm, the refractory fibre inwall all serves as a contrast with steel plate 6 as insulation board, the thickness of steel plate is 1-20mm, the weldering of cover body steel plate outer surface is a skeleton with shaped steel 5, the suspension ring 4 that hang on cover usefulness are together established in last cover top center position, the height of nowel 2 is lower than the height of the steel ingot on the serpentine of upright placement nowel bottom, near base position three rake cinder holes 7 are set equably along its length in following box body length direction one side, the another side is provided with four rake cinder holes along its length equably, but the rake cinder hole seals with the rake slag door 11 of switch, building with thickness on the bottom surface steel plate of base 3 is refractory brick and the insulating brick of 150-300mm, and refractory brick upper berth thickness is the block serpentine about 200mm.

Claims (3)
1, a kind of stay-warm case that is used to transport red-hot steel ingot is applicable to and loads the red-hot steel ingot that steel mill waters the demoulding behind the steel.Technical characterictic of the present utility model is that stay-warm case is the cuboid of a steel plate system, is made up of last cover, nowel and base.Cover body steel plate inwall is sticking with heat-barrier material, form a heat insulation layer, there is the layer of metal plate on the heat insulation layer surface as insulation board, the nowel height is a little less than the height that uprightly is placed on the steel ingot at the bottom of the case in it, a side of its length direction is provided with three rake cinder holes along its length equably near base position, and the another side is provided with four rake cinder holes.
2, steel ingot stay-warm case according to claim 1 is characterized in that described insulation board is a steel plate, and thickness is 1-20mm.
3, steel ingot stay-warm case according to claim 1 is characterized in that the serpentine of the even shakedown of upper surface of described base with bulk.
