Abstract
The utility model discloses a torpedo hot metal mixer car, and belongs to the technical field of steel smelting processing. The utility model is composed of a tank body, a running gear, etc., wherein, the side lower part of the tank body is provided with a taphole, a furnace liner of the taphole is made of refractory material, and a shell body of the taphole is provided with a special shield device. The utility model avoids iron melt loss by the splash of lots of iron melt, improves job conditions, reduces environmental pollution, relieves complete set complex transmission and a control device to make the tank body rotated, and lowers the manufacturing cost of the torpedo hot metal mixer car. The utility model is especially suitable for producing cast iron in steel industries.
Description
The utility model belongs to the smelting processing technique field of iron and steel, particularly molten iron is transported to a kind of torpedo hot metal mixer car of making steel and molten iron being transported to the pig machine ingot bar.
Torpedo hot metal mixer car is the visual plant that transports molten iron to steel-making and molten iron is transported to the pig machine ingot bar.Because torpedo hot metal mixer car molten iron area of dissipation is little, reduced the temperature drop of molten iron greatly, general opened type hot-metal bottle temperature drop is 50～150 ℃/h, the torpedo hot metal mixer car temperature drop is 10～20 ℃/h only; And adopt torpedo hot metal mixer car can save the mixed iron blast of steel-making, and reduce hot metal temperature drop, the environmental pollution of molten iron when mixed iron blast is converted down, also reduced the holding time of steel-making crane simultaneously, saved a large amount of capital expenditures.Therefore torpedo hot metal mixer car is used widely in steel plant.The tradition torpedo hot metal mixer car is subjected to iron and taps a blast furnace all to use the same opening at its top, molten iron drop big (about 3.5m) when causing torpedo hot metal mixer car to tap a blast furnace.Particularly when cast iron, because of the molten iron drop is big, molten iron splashes in a large number, produces about 5% molten iron loss, a 2500m
3The loss of one day molten iron of blast-furnace cast iron just is equivalent to a 120m
3The daily output of blast furnace, daily loss just can reach 250,000 yuan.But also cause serious environmental to pollute, and bring inconvenience for the operation in pig machine workshop, the labour intensity of residue, iron cleaning is big, condition is poor, and the people can't be near molten iron trough during cast iron, and inconvenience safeguards that operating environment is very abominable.On the other hand, tank body need rotate molten iron is flowed out from the top tapping hole when torpedo hot metal mixer car tapped a blast furnace, in order to guarantee the stable of molten iron stream, the rotation of tank body also needs to carry out speed governing, cause torpedo hot metal mixer car to have to increase the manufacturing cost of torpedo hot metal mixer car and the complexity of control with the complicated drive apparatus of a last cover.
The purpose of this utility model is to provide a kind of big, the molten iron of molten iron drop serious defective of splashing when overcoming traditional torpedo hot metal mixer car cast iron, simplifies its process of tapping a blast furnace; Save drive apparatus, simple in structure, the torpedo hot metal mixer car of low cost of manufacture.
The purpose of this utility model realizes as follows: torpedo hot metal mixer car is made up of tank body, running gear etc.The torpedo hot metal mixer car tank body leaves a tapping hole in addition at the side lower part of tank body except that an opening at top, the furnace lining of iron oral area position adopts refractory material to build by laying bricks or stones, and special-purpose iron mouth block protecting device is set on the tapping hole housing.Make that torpedo hot metal mixer car is subjected to iron, the separation of tapping a blast furnace.
In technique scheme, because tapping hole is opened side lower part at the torpedo hot metal mixer car tank body, tapping a blast furnace need not to tumble, thereby the molten iron loss of having avoided molten iron to splash in a large number producing has improved condition of work, has reduced environmental pollution; And need not to tumble because tap a blast furnace, torpedo hot metal mixer car is then removed a whole set of complicated transmission and the control device that tank body is rotated from, reduces the manufacturing cost and the manufacturing technology requirement of torpedo hot metal mixer car greatly.
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described further.
Fig. 1 is the torpedo hot metal mixer car schematic diagram
Fig. 2 is that tapping hole A is to schematic diagram
Fig. 3 is the tapping hole generalized section
Among the figure, 1 is tank body, and 2 is running gear, and 3 is tapping hole, and 4 are the plug brick, and 5 is block protecting device.
Torpedo hot metal mixer car is made up of tank body 1, running gear 2 etc.The side lower part of the tank body 1 of torpedo hot metal mixer car is opened a tapping hole 3 in addition, and the furnace lining at tapping hole 3 positions adopts refractory material to build by laying bricks or stones, fills in brick 4 with tapping hole 3 jam-packs, and special-purpose block protecting device 5 is set on tapping hole 3 housings.When opening tapping hole 3, earlier block protecting device 5 is removed, taken out plug brick 4 again, look stemming sintering degree then, disclose or bore, just can comparatively easily tapping hole 3 be opened with simple and easy air drill with drill rod.When needing in the process of tapping a blast furnace, then can utilize plug brick 4 that it is blocked up temporarily with tapping hole 3 stifled going up.After torpedo hot metal mixer car has gone out iron, earlier with blast furnace anhydrous stemming filling tapping hole 3, use a special plug brick 4 with iron mouth jam-pack again, the outside will fill in brick 4 with block protecting device 5 again and be tacked, and with the safety of assurance tapping hole 3, prevent leak-stopping iron.
After torpedo hot metal mixer car did not rotate, tank body then can develop into various structural shape, as square, oval, flute profile, and other nonaxisymmetrical structural shape.
