Description

Train ladle whole-process automatic adding, gets lid arrangement

Technical field

The utility model relates to a kind of train ladle and adds and get lid arrangement.

Background technology

As the novel concept proposed in recent years; essence is that high efficiency of energy utilizes, the problem of development of clean energy; core is energy technology and the innovation of energy-conserving and emission-cutting technology, industrial structure innovation and production technology innovation etc. this Economic Development Mode is different from the model of rough increasing economic of traditional iron and steel enterprise, and it is the mode of a kind of practicable of the contradiction between problem and human society sustainable development such as global warming, crisis of resource and environment produced under processing traditional economy growth pattern.

The main production process of iron and steel enterprise is ironmaking (ironworks)-steel-making (steel mill)-continuous casting (continuous casting workshop)-product (section bar factory, board mill etc.).In whole production process, the technique circulation between each workshop can reduce along with temperature, energy loss.And the every temperature of procedure to product has strict requirement, in order to ensure the normal production of every procedure, only having by a large amount of energy resource consumption of preceding working procedure, improving temperature.The energy volatilization of steel product is fast, and along with the rising of temperature, energy ezpenditure can be doubled and redoubled, so the heat preservation energy-saving level of inter process directly can have influence on the production cost of product.

In current domestic iron and steel enterprises, iron-smelter generally adopts ladle splendid attire molten iron, by hot-metal ladle and carriage, molten iron is transported to steel mill's desulfurization station and carries out desulfurization and skim, and is then lifted to converter station by driving and molten iron is blended into converter smelts further.According to different product structures and programming and distribution, iron-smelter differs greatly to the distance of steel mill, in older enterprise, the distance of Liang Ge factory has more than 5 kilometers usually, in recent years newly-built enterprise, at 500-1000 meters not etc., and this section of distance is outdoor, has very large potential safety hazard for the distance of Liang Ge factory.In steel mill's Molten Iron Transportation processes all at present, molten iron handbag mouth is unlimited, and molten iron directly contacts with air, molten iron and ladle and Air Temperature Difference large, constantly there is heat exchange, a large amount of heats distributed, if be also prone to accidents at sleety weather.By carrying out tracking measurement to many enterprises, molten iron in ladle from blast furnace out temperature be 1500 ° (molten iron mean temperature) left and right, when ladle runs to desulfurization station, temperature has been reduced to about 1340 ° (molten iron surface temperatures), sometimes lower.Comprehensive molten steel decreased average 120 DEG C, it is 10000Kcal/ ton molten iron to air heat radiation value that the heat radiation that molten steel reduces 60 ° is equivalent to molten iron per ton few, and be equivalent to the combustion heat release of 1600 kilograms of standard coals, such energy loss is very large.Ladle is opened wide big for environment pollution simultaneously, lowers service life of equipment.

Summary of the invention

The purpose of this utility model is to provide a kind of rational in infrastructure, and train ladle whole-process automatic the adding of reducing molten iron heat loss gets lid arrangement.

Technical solution of the present utility model is:

A kind of train ladle whole-process automatic adding, gets lid arrangement, it is characterized in that: comprise the iron hired car that iron bag is housed, and dress iron clad wrapped by iron, and iron clad is made up of left and right half lid; Left and right half lid is connected with a lid mechanism for opening/closing respectively; Described lid mechanism for opening/closing comprises first, second bending arm; The upper arm of the first bending arm is connected with half rear end cover by bearing pin, the underarm of the first bending arm by bearing pin be contained in iron hire a car on fixed leg be connected, be contained in iron hire a car on flexible push rod be connected with the underarm of the first bending arm; The upper arm of the second bending arm is connected with half front end covered, and the underarm of the second bending arm to be hired a car with iron by bearing pin and is connected.

The utility model is rational in infrastructure, and can reduce ladle widely and connect scattering and disappearing of heat in molten iron and the process of falling molten iron, saving energy consumption, reduces costs, and improve operating personnel's working environment.

Major advantage: reduce the heat radiation that hot-metal bottle wraps in transit mouth, thus reduce molten iron heat loss.Reduce the discharge of tank mouth noxious fume, improve air ambient.The slagging scorification of effective control tank mouth, improves molten iron utilization rate.Improve the service life of tank inner lining refractory material.Rainy season heavy rain can be prevented iron water mitigation in tank.Reduce the use of heat preserving agent in hot-metal bottle.

Detailed description of the invention

A kind of train ladle whole-process automatic adding, gets lid arrangement, comprises the iron hired car 2 that iron bag 1 is housed, and dress iron clad 3 wrapped by iron, and iron clad is made up of left and right half lid; Left and right half lid is connected with a lid mechanism for opening/closing respectively; Described lid mechanism for opening/closing comprises first, second bending arm 4,5; The upper arm of the first bending arm is connected with half rear end (one end namely far away with Ban Gai junction, left and right) covered by bearing pin, the underarm of the first bending arm by bearing pin be contained in iron hire a car on fixed leg 6 be connected, the flexible push rod 7(be contained on iron hired car can adopt the forms such as Electrohydraulic push rod, hoist engine, hydraulic cylinder, electric cylinder) be connected with the underarm of the first bending arm; The upper arm of the second bending arm is connected with half front end (namely with one end that Ban Gai junction, left and right is nearer) covered, and the underarm of the second bending arm to be hired a car with iron by bearing pin and is connected.

The course of work: when uncapping, switches on power, and dynamical element (Electrohydraulic push rod, hoist engine, hydraulic cylinder, electric cylinder etc.) promotes linkage (i.e. first, second bending arm) and rotates backward, and drives cover to move backward.After completing by iron, under blast furnace, implement pass lid operation (closing lid process about 1 minute), close after lid completes and leave for the place's of falling iron wait.When waiting for overhead traveling crane at the place of falling iron, be in and close lid state.Overhead traveling crane hangs ladle and to fall before iron certain hour in advance and carry out operation of uncapping.The iron that falls completes to be got back to after on automobile until ladle, carries out to close to cover operate and leave for blast furnace place.
