The invention discloses an electro-hydraulic drive M-shaped steel ladle capping and decapping device, which relates to the structure of a whole-course full-automatic capping and decapping device of a high-temperature melt container in metal smelting. The electro-hydraulic drive M-type steel ladle capping and decapping device comprises a fixed frame, wherein the fixed frame is fixedly connected with an electro-hydraulic push rod and a connecting rod mechanism; the fixed frame is hinged to an M-shaped prong assembly; the electro-hydraulic push rod is connected with the connecting rod mechanism; the connecting rod mechanism is hinged to the M-shaped prong assembly. According to the electro-hydraulic drive M-type steel ladle capping and decapping device disclosed by the invention, the electro-hydraulic push rod is stretched to drive the connecting rod mechanism to control the swinging of the M-shaped prong assembly, an included angle between the M-shaped prong assembly and the horizontal plane is regulated, and capping and decapping are realized by the movement of a buggy ladle. High-cost heat energy is avoided and prevented from outwards losing to the outside from a steel ladle lining used for containing molten steel and liquid steel, the steel mill production cost is lowered, the operation condition is improved, and the production rate is improved.
Description
Technical field
The whole process that the present invention relates to high-temperature fusant container in metal smelt is automatically added a cover the structure with cover-taking off device.
Background technology
Energy-saving and emission-reduction work has become national overall strategy target, and iron and steel enterprise is the big power consumer.At present, ladle in use causes the approach of heat-energy losses generally to consist of two parts, and the one, the heat by conduction between cylinder-packing and involucrum, the 2nd, by the ladle top open part, fall apart to the radiant heat of air.In order to solve the second portion problem of " faling apart to the radiant heat of air by the ladle top open part ", some iron and steel enterprises have started the ladle stamp operation already on conticaster, yet, because existing ladle stamp operation must have been assisted by overhead traveling crane, make this technology operability in actual applications be subject to very big restriction, thereby make this technology mostly only be confined to the use of continuous-casting steel pouring stage, can't accomplish that in ladle whole recycles process, all making steel ladle cover cover on ladle is incubated, while causing molten iron and empty bag in ladle the temperature of ladle whole run off in recycling process serious, cause energy loss, after filling with molten iron simultaneously or just having poured molten iron, sky wraps in whole recycling in process does not have steel ladle cover to cover, high temperature and the environment temperature in iron and steel enterprise's factory building in ladle produce convection current, cause the dust from flying in factory building and contaminated environment causes damage to online workman, therefore, more existing ladle stamp operations reach far away the desired energy-conservation and environment protecting of steelmaker author, and the most of heat scattered and disappeared molten steel in ladle refractory lining and bag is not effectively controlled yet.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, provide a kind of electricity M shaped steel bag that surges to add a cover and cover-taking off device, avoid and stop expensive heat energy outwards to scatter and disappear from the ladle liner of containing molten steel and molten steel, reducing steel mill's production cost, improve operating condition and boost productivity.
The object of the present invention is achieved like this: the electricity M shaped steel bag that surges is added a cover and cover-taking off device, comprise fixed frame, be fixedly connected with Electrohydraulic push rod and linkage on fixed frame, be hinged M type prong assembly on fixed frame, Electrohydraulic push rod connects linkage, and linkage and M type prong assembly are hinged.
M type prong assembly of the present invention comprises two long slope tooth bars and a short slope tooth bar, short slope tooth bar is arranged between two long slope tooth bars, two long slope tooth bars are fixedly connected with by two box beam with a short slope tooth bar, in two box beam wherein box beam with each long slope tooth bar, with short slope tooth bar, by channel-section steel, be fixedly connected with respectively.After assembling, be welded, shape is similar to " M ".
The present invention is flexible by Electrohydraulic push rod, the swing of drivening rod mechanism controls M type prong assembly, and the angle of adjustment prong assembly and horizontal plane, add a cover and take off lid by the mobile realization of buggy ladle.Significantly reduce thermal loss ladle in whole in recycling process in iron and steel enterprise, thereby the cooling degree that in the minimizing ladle, molten steel experiences, the reducing of this energy loss will change into important production economy benefit, and topmost benefit shows produces and the quality of the cost of operation, product improves and the efficiency of producing improves.
Use the present invention can make steel ladle cover all cover all the time on ladle in being close to whole ladle use cycle period, the direct benefit brought thus comprises:
Reduce the cooling of the interior molten steel of bag; Once ladle enters online and recycles, the ladle preheating between heat can be exempted; The ladle turnover is accelerated; Reduce the usage quantity of online ladle; Reduce the temperature fluctuation of molten steel in ladle, tundish and crystallizer; Exempt in casting process the auxiliary preheating to tundish; Yield of alloy is more stable; The steel scrap reduced in ladle produces; Save the use amount of heat preserving agent; The cleaning demand of minimizing to ladle edge and slag line, thus the mechanical damage fire-resistant to cylinder-packing reduced; Improve the free casting rate of steel ladle sliding water gap; Reduce operating delay; Reduce energy resource consumption; Improve the safeguard protection of plant personnel; Whole plant environment temperature and improving, pollute and reduce.
Use when of the present invention, by technological operation optimization, realize more being benefited, and these are benefited and are summarized as follows:
The molten steel tapping temperature can be lowered the 20-30 degree; Only need a ladle preheater to support production operation.This preheater only is put into and produces new heating of building cylinder-packing before for ladle; The interior degree of superheat of molten steel on conticaster of bag can be reduced and be more stable; Because the molten steel tapping temperature reduces, deoxidier consumption is lowered; Fire-resistant erosion on converter and ladle is reduced, so the furnace life/bag is extended age; Molten steel operational processes time shorten to different phases such as smelting, Ladle Treatment and continuous castings; Potential Workshop Production rate obtains and improves; Process operation output is improved; Can obtain more effectively utilizing production equipment in production schedule arrangement; Workshop labour demand reduces; The operating space of ladle service area can dwindle; The generation of waste material, as reactant byproduct and fire-resistant waste product etc. are reduced; Product quality is improved;
Difference according to appointed condition, operating environment and the managerial skills of steel mill, use the steel ladle full stroke covering energy conserving system, attainable ton steel cost savings is generally between 20 to 25 yuan, the steel mill that also just means a year 9000000 tons of output of steels, the use of invar bag full stroke covering energy conserving system, the energy saving profit of bringing in a year just reaches 1.8～2.25 hundred million yuan.
The present invention mainly solves the second portion problem of " faling apart to the radiant heat of air by the ladle top open part ", by the present invention by steel ladle cover except at molten steel, coming out of the stove process, all the time cover on ladle in all the other processes that recycle online, the ladle top open part is significantly reduced to airborne heat loss through radiation amount; And, in the use of ladle circulation, be no matter that the lid of adding a cover or take off of steel ladle cover all completes automatically by Design of Mechanical Structure cleverly, neither need overhead traveling crane, do not need manpower intervention yet, bring huge energy-saving benefit to iron and steel enterprise.
