Abstract
The invention relates to a molten iron pretreatment slag removing device and a process using the device to remove slag. The slag removing device comprises a molten iron tipper, molten iron tipper tracks, a slag receiving trolley, slag receiving trolley tracks and a slag removing machine, wherein the molten iron tipper tracks and the slag receiving trolley tracks are connected with a slag removing area, a working platform is arranged near the slag removing area, the slag receiving trolley tracks pass through the underside of the working platform, and the slag removing machine is arranged on the working platform. The corresponding process comprises the following steps that: the molten iron tipper and the slag receiving trolley move forwards to proper slag receiving working positions in the slag removing area along the molten iron tipper tracks and the slag receiving trolley tracks respectively; a tipping mechanism of the molten iron tipper is controlled to overturn a molten iron tank and expose the slag surface; the slag removing machine is controlled to remove the slag; and after removing the slag, the slag receiving trolley moves to a slag disposal pit to pour the slag, the molten iron tank restores, and the molten iron tipper moves away. The molten iron slag removing device has reasonable and simple device configuration and less investment of basic facilities, and is comparatively suitable for small steel mills; besides, the process special for the device is concise to achieve requirements of a molten iron pretreatment slag removing process.
Description
Technical field
The invention belongs to metallurgical technology field, especially relate to a kind of molten iron pretreatment slag skimming equipment, and the technology of utilizing this equipment to skim.
Background technology
The technology that extensively adopts in the existing STEELMAKING PRODUCTION is: blast furnace → hot metal pretreatment → skim → converter smelting.Hot metal pretreatment in the stage as far as possible with removal of sulphur.Be rich in a large amount of sulphur in the desulfurization slag owing to the molten iron slag of bringing blast furnace in the hot metal charging process into and hot metal ladle desulfurization generation, these slags are under converter hyperoxia voltinism condition, wherein most sulphur can enter in the molten steel, cause postorder operation production cost to improve, therefore, the slag that must will float over before molten iron is blended into converter on the molten iron face is removed.The slagging-off of technique means such as most of enterprises skim mechanically, vacuum slag absorbing.
The specific equipment that present enforcement machinery is skimmed mainly contains following composition: tipple, slag removal machine or the arm of skimming that the device of responsible molten iron transportation, realization molten iron pour in down a chimney, the device that carries slag ladle and responsible transportation etc.The concrete outfit of above-mentioned specific equipment and decoration form can be not quite similar according to the needs of slag skimming process.For example: publication number be the Chinese patent of CN101024245A disclosed be a kind of slag skimming method of cylinder slag removal machine.Therefore the specific equipment that is applied to this method is installed in slag removal machine on the roller equipment exactly, comes the mobile relatively poor slag of special disposal; And notification number to be the Chinese patent of CN1241704C proposed a kind of slag method and special-purpose device of skimming of dragging for efficiently owing to adopt rotary type to drag for the slag technology, its device of skimming is made up of rather than slag removal machine two slags rakes.Above-mentioned patent can both solve skim not thorough, the technical problem that the slagging-off rate is low.But simultaneously, because these methods improve the efficient of skimming emphatically, carry out and get up to have certain complicacy, therefore special-purpose basis and equipment input are very expensive, are fit to be applied to the bigger enterprise of industrial scale.For medium-sized and small enterprises, need a kind of simple and easy, molten iron pretreatment slag skimming specific equipment and corresponding technology that infusion of financial resources can take into account efficient less, again.
Summary of the invention
The molten iron pretreatment slag skimming equipment that the present invention adopts comprises the molten iron tipping car, molten iron tipping car track, be subjected to the slag chassis, be subjected to slag trolley track and slag removal machine, wherein, molten iron tipping car track, be subjected on the slag trolley track all to be connected with the zone of skimming, workplatform is arranged near the zone of skimming, passed under workplatform by the slag trolley track, slag removal machine is installed on the workplatform.Like this, the molten iron tipping car, be subjected to the slag chassis can both march to the work of skimming in the zone of skimming.
Preferably, molten iron tipping car track centerline, coexisted in the vertical plane by slag trolley track medullary ray and the slag removal machine medullary ray of skimming.
The technology of utilizing aforesaid device to skim is such: the molten iron tipping car, be subjected to the slag chassis separately along molten iron tipping car track, proceeded to by the slag trolley track to skim the suitable slag station that is subjected in the zone; Control molten iron tipping car tilting mechanism upset iron ladle exposes the top of the slag; The control slag removal machine is skimmed; Skim finish after, be subjected to the slag chassis to move to the deslagging of slag field, iron ladle resets, the molten iron tipping car leaves.
The whole plant configuration is rationally simplified, and the Infrastructure less investment relatively be fit to small-sized steel mill and use, and corresponding technology is succinct, also can reach the requirement of molten iron pretreatment slag skimming process simultaneously.
Description of drawings
Fig. 1 is the composition diagram of molten iron pretreatment slag skimming process specific equipment of the present invention.
Fig. 2 shows molten iron pretreatment slag skimming station site plan of the present invention.
Embodiment
As Fig. 1, shown in 2, the specific equipment of molten iron pretreatment slag skimming process has the hot-metal bottle tipping Car Track, on molten iron tipping car track back and forth the molten iron tipping car 1 of operation, be subjected to the slag trolley track, be subjected on the slag trolley track back and forth operation be subjected to slag chassis 3, and workplatform and be installed in slag removal machine 2 and watch-keeping cubicle on the workplatform.Wherein, molten iron tipping car track, be subjected on the slag trolley track all to be connected with the zone 4 of skimming, workplatform is arranged on skims near regional 4, passed under workplatform by the slag trolley track.
The position at slag removal machine 2 places is the position of skimming.Molten iron tipping car 1 runs on molten iron and strides and skim between the position, can pass from slag removal machine 2 workplatformes below by slag chassis 3, runs on and skims between position and the slag field.Especially, molten iron tipping car track centerline, slag removal machine skim medullary ray, coexisted in the vertical plane by slag trolley track medullary ray.
The iron ladle that molten iron tipping car 1 transportation contains scum silica frost along the orbital motion of molten iron tipping car to the position of skimming, enter the station put in place after, be subjected to this moment slag chassis 3 also to be subjected to the slag trolley track to run to the position of skimming from edge, slag field.Control molten iron tipping car 1 tilting mechanism flips an angle (0-40 degree) iron ladle, exposes the top of the slag.Control slag removal machine 2 arm of skimming is flexible, revolution, and pumping arm action finishes that scum silica frost is grilled in the slag basin that is subjected on the slag chassis.Be subjected to slag chassis 3 to run to the deslagging of slag field then.The molten iron tank body resets, and molten iron tipping car 1 leaves, and runs to molten iron and stride.
