Description
Technical field
The utility model relates to iron-smelting blast furnace auxiliary facility, refers to a kind of two iron mouth blast furnace of single casting house with bridge type iron runner particularly.
Background technology
Owing to being subject to the impact in place, the blast furnace of part iron work adopts the design of rectangle list casting house, and two iron mouths become 30 degree of angles, configure tap drain respectively, share a set of slag iron treatment system, there is a point of crossing in two tap drains slag iron runner separately, this point of crossing exists following defect:
1, can not simultaneously operation, as run into the special working of a furnace, two iron mouths cannot be met and tap a blast furnace simultaneously.
2, iron mouth for subsequent use operation cannot be switched to from operation iron mouth immediately, the point of crossing that slag iron runner exists must be poured into a mould again, pour into iron runner by former slag runner or become slag runner can use iron mouth for subsequent use operation by former iron runner place mat.
3, slag iron runner maintenance cost is increased.Each replacing tap drain, must to slag iron runner point of crossing carry out transformation complete after can normal operation.Extra consumption mould material and wasting time, brings disadvantageous effect to blast fumance.
Summary of the invention
The utility model overcomes above-mentioned deficiency exactly, the two iron mouth blast furnace of single casting house with bridge type iron runner provide a kind of independently working, being independent of each other.
The two iron mouth blast furnace of single casting house with bridge type iron runner of design described in the utility model, comprise single casting house body of heater, described body of heater being provided with angle is the operation iron mouth of 30 ° and iron mouth for subsequent use, described operation iron mouth side is provided with the iron flask for splendid attire molten iron, described iron mouth side for subsequent use is provided with the slag ladle for splendid attire scum, described operation Tie Kou exit be provided with respectively with iron flask and the tank connected operation iron runner of slag and operation slag runner, described Tie Kou exit for subsequent use is respectively arranged with and iron flask and the tank connected iron runner for subsequent use of slag and slag runner for subsequent use, wherein, described operation slag runner is crossing with iron runner for subsequent use, its special character is: spatially lower than bottom iron runner for subsequent use bottom described operation slag runner, described operation slag runner and iron runner top for subsequent use flush, in described intersection, iron runner for subsequent use is set to trench and passes a bridge, be overlapped on operation slag runner, described trench is passed a bridge and is arranged with support, described support is connected with operation slag runner.
Further, described support is arranged on operation slag runner sidewall.
Further, described in be supported with two, positioned opposite on operation slag runner two side.
The utility model has the advantage of: by considering the performance etc. of operation slag runner and iron runner for subsequent use, improve the degree of depth of iron runner bottom of trench for subsequent use, operation slag runner arranges one end trench pass a bridge, gap bridge is made to be overlapped on iron runner for subsequent use, form bridge like passage, and support is set under trench is passed a bridge, support trench and pass a bridge.This design solves slag iron runner in the past and intersects interfering with each other of causing, the problems such as two iron mouths can not work simultaneously, switch operating iron mouth inconvenient, tap drain turnover job is loaded down with trivial details, improve blast furnace change the working efficiency of iron mouth operation and tackle the ability of some special working of a furnace, decrease operation and the cast cost of tap drain overhaul.
Accompanying drawing explanation
Fig. 1 is the structural representation of the two iron mouth blast furnace of single casting house with bridge type iron runner.
Fig. 2 is the A place structure for amplifying schematic diagram of Fig. 1.
In figure: single casting house body of heater 1, operation iron mouth 2 (wherein: operation iron runner 2.1, operation slag runner 2.2), iron mouth 3 (wherein: iron runner 3.1 for subsequent use, trench passes a bridge 3.11, slag runner 3.2 for subsequent use) for subsequent use, iron flask 4, slag ladle 5, supports 6.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The two iron mouth blast furnace of single casting house with bridge type iron runner shown in figure, comprise single casting house body of heater 1, body of heater 1 being provided with angle is the operation iron mouth 2 of 30 ° and iron mouth 3 for subsequent use, operation iron mouth 2 side is provided with the iron flask 4 for splendid attire molten iron, iron mouth 3 side for subsequent use is provided with the slag ladle 5 for splendid attire scum, operation iron mouth 2 exit is provided with the operation iron runner 2.1 and operation slag runner 2.2 that are connected with iron flask 4 and slag ladle 5 respectively, iron mouth 3 exit for subsequent use is respectively arranged with the iron runner for subsequent use 3.1 and slag runner for subsequent use 3.2 that are connected with iron flask 4 and slag ladle 5, wherein, operation slag runner 2.2 is crossing with iron runner 3.1 for subsequent use, spatially lower than bottom iron runner 3.1 for subsequent use bottom operation slag runner 2.2, operation slag runner 2.2 and iron runner for subsequent use 3.1 top flush, in described intersection, iron runner 3.1 for subsequent use is set to trench and passes a bridge 3.11, be overlapped on operation slag runner 2.2, trench gap bridge 3.11 is arranged with two and supports 6, supporting 6 lays respectively on operation slag runner 2.2 two side, positioned opposite in order to support trench gap bridge 3.11.
During build, first the operation slag runner 2.2 of operation iron mouth 2 is dug low slightly downwards, and each mould material one supports 6 on operation slag runner 2.2 two side of iron runner for subsequent use 3.1 infall with iron mouth 3 for subsequent use, pass a bridge 3.11 in order to place trench.Nai Cai factory customizes a trench according to field measurement size and passes a bridge 3.11, trench gap bridge 3.11 is placed in mould material and supports on 6, and is fixed by trench gap bridge 3.11 by mould material.
In order to ensure the normal operation of operation slag runner 2.2 energy, trench gap bridge 3.11 must possess following technical characteristic:
(1) the resistance to materials that trench gap bridge 3.11 uses must possess enough high temperature resistances, resistance to deformation, resistance to erosion, corrosive power;
(2) trench pass a bridge 3.11 with its below operation slag runner 2.2 must possess enough height, avoid trench to pass a bridge when operation slag runner 2.2 quantity of slag is excessive below 3.11 crossing slag scarce capacity to cause and block up.
(3) trench gap bridge 3.11 conveniently must be installed, dismantle.
This programme by experiment, solve slag iron runner in the past and intersect interfering with each other of causing, the problems such as two iron mouths can not work simultaneously, switch operating iron mouth inconvenient, tap drain turnover job is loaded down with trivial details, improve blast furnace change the working efficiency of iron mouth operation and tackle the ability of some special working of a furnace, decrease operation and the cast cost of tap drain overhaul.Cost-saved 1,250,000 yuan every year.
