Description
Technical field
The utility model relates to steelmaking system, relates in particular to a kind of full stroke covering for ladle and the device of taking off lid.
Background technology
Ladle is as the container of access molten steel, and it directly affects the variation of liquid steel temperature in tapping and Sheng steel process at the hot state of producing circular flow.The production turnover technological process of ladle: converter (or electric furnace) connects steel, and---------hot repair---waits steel waiting to water steel in refining.In this technological process process, in use the most of the time is all uncovered to the ladle of China overwhelming majority steel mill, do not take the measure of adding a cover (some steel mills only water the steel stage at continuous casting platform and carry out the ladle stamp operation), the external heat loss through radiation of ladle is serious.By adding a cover on ladle, greatly reduced the heat loss through radiation of molten steel surface and empty Bao Naicai, can make converter reduce tapping temperature; Can be so that in ladle, the upper and lower temperature of molten steel be even, more favourable to continuous casting safety; Can reduce the rapid heat cycle of ladle lining fireproof material, improve the anti-material life-span, reduce refractory consumption.Due to the apparent energy-saving effect of ladle stamp, it has become an energy-saving and cost-reducing important means of iron and steel enterprise.
At present, some iron and steel enterprises have all carried out the ladle stamp operation on conticaster, yet this technology only is confined to the continuous-casting steel pouring stage, use, and can't accomplish all to make steel ladle cover cover on ladle in ladle whole recycles process, and only partial insulation is energy-conservation.In addition, indivedual steel mills have adopted fluid pressure type steel ladle full stroke covering and cover-taking off device, but its floor area is large, and space requirement is high, and investment is many, install complicated and the running orbit accuracy requirement is tight, and this device has been gone into operation in China, and to carry out spread very difficult in steel mill.
The utility model content
That technical problem to be solved in the utility model is to provide is simple in structure, cost is low, small investment, floor area are little, can suit measures to local conditions to install, steel ladle full stroke covering and cover-taking off device easy to maintenance.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of ladle stamp and cover-taking off device, for adding a steel ladle cover or open existing steel ladle cover on ladle on ladle, this device comprises steel rope, winch, for hook steel ladle cover suspender, column, crossbeam and pulley, described winch is connected with an end of described steel rope, the other end of described steel rope is connected with described suspender, the lower end of described column is fixed on the ground, and described crossbeam is fixedly connected with described column upper end; The below of described crossbeam is hung with described pulley, and described steel rope passes from the upper surface of described pulley, and described winch is arranged on the ground.
Further, described pulley is at least two, and is separated with certain distance between between described pulley.
Further, described pulley is 3.
Further, described suspender below is provided with the L shaped member for the hook steel ladle cover.
The beneficial effects of the utility model are:
(1) simple in structure, cost is low, small investment, floor area are little, it is simple and easy to maintenance to install.
(2) owing to adopting the utility model, steel ladle cover nearly all covers on ladle in whole use cyclic process, thereby has stoped heat loss through radiation, greatly reduces the loss of energy.
(3), owing to adopting the utility model, can make converter reduce tapping temperature; Can be so that in ladle, the upper and lower temperature of molten steel be even, more favourable to continuous casting safety.
(4) owing to adopting the utility model, can exempt the online preheating of turnover ladle, reduce energy consumption; Cancel the input of molten steel insulation material, environmental protection more.
(5) owing to adopting the utility model, can reduce the rapid heat cycle of ladle lining fireproof material, improve the anti-material life-span, reduce refractory consumption.
