Abstract
The utility model provides a buoy for marking the height of liquid steel of a tundish. The buoy consists of a cross beam, a connection rod and a floating plate; the connection rod is welded in the middle of the cross beam, and the lower end of the connection rod is welded with the floating plate. When a first tank is poured during the continuous steel casting, the cross beam is loaded on a cover of the tundish, the distance between the floating plate at the lower part and the bottom of the tundish is shorter than the distance between an overflow groove of the tundish and the bottom of the tundish, so that the liquid steel of the tundish is in contact with the floating plate firstly. When the liquid steel in the tundish reaches the height set by the buoy, the buoy sways to float upwards under the action of the buoyancy of the liquid steel, so that an operator can rapidly control the weight of the liquid steel in the tundish to avoid the tundish overflowing. The buoy provided by the utility model is simple to operate and safe and convenient, not only can the phenomenon of overflowing of the tundish be avoided, but also great help is provided for stabilizing the pouring state and improving the casting quality.
Description
Technical field
The utility model belongs to continuous casting auxiliary implement field, and is particularly a kind of for demarcating the cursory of Metal in Tundish height.
Background technology
The continuous casting tundish is a kind of carrying ladle molten steel, then molten steel is diverted to a kind of high-temperature resistant container in the crystallizer.The charge weight of Metal in Tundish directly has influence on MOLTEN STEEL FLOW state, inclusion morphology and ascent rate, and is low such as the Metal in Tundish charge weight, not only on the mass formation impact of strand, easily causes slag bleed-out accident when serious.Therefore, the operator controls to maximum with the charge weight of molten steel in the tundish as far as possible, it namely is the height that the molten steel face reaches the tundish overflow launder, but the life-span of each tundish is different, volume is different, the charge weight of molten steel is also just different, often occurs opening in operation watering tundish overflow phenomena behind the first tank.
Summary of the invention
The utility model aims to provide a kind of simple in structure, and is easy to operate, can grasp rapidly Metal Weight in the tundish, avoids the cursory of demarcation Metal in Tundish height that the tundish overflow occurs.
For this reason, the utility model has been taked following technology solution;
A kind ofly demarcate the cursory of Metal in Tundish height, it is characterized in that, formed by crossbeam, connecting rod and kickboard; Be welded with a connecting rod in the middle of the crossbeam, connecting rod lower end welding kickboard.
Using method of the present utility model and beneficial effect are:
The utility model continuous-casting steel pouring whenever water time the first tank the time put into pouring basket lid, its crossbeam load is on pouring basket lid, the kickboard of below distance at the bottom of the tundish will be lower than tundish overflow launder distance at the bottom of the tundish, makes Metal in Tundish contact first the utility model, reaches the forecast purpose.When Metal in Tundish reaches cursory setting height, cursoryly under the buoyancy of molten steel, rock floating, at this moment the operator just can control rapidly the weight of molten steel in the tundish, thereby avoids the generation of tundish overflow.
The utility model is simple to operate, and is safe and efficient, not only avoided the tundish overflow phenomena, and to stablizing casting condition, improving slab quality has very big help.
Description of drawings
Accompanying drawing is for demarcating the cursory use view of Metal in Tundish height.
Among the figure: overflow launder 1, crossbeam 2, connecting rod 3, kickboard 4, pouring basket lid 5, tundish 6, molten steel 7.
The specific embodiment
By accompanying drawing as seen, the utility model is comprised of crossbeam 2, connecting rod 3 and kickboard 4.Connecting rod 3 of welding in the middle of crossbeam 2 makes it to form one "T"-shaped, in square kickboard 4 of the lower end of connecting rod 3 welding, namely makes the cursory of the utility model again.Crossbeam 2 and connecting rod 3 are selected respectively the steel pipe manufacturing of 550mm and 430mm length, and square iron plate 3 adopts 150 * 150mm square iron plate to process.Then when whenever watering time the first tank with the cursory pouring basket lid 5 of putting into, by crossbeam 2 with cursory load on pouring basket lid 5, when tundish 6 interior molten steel 7 reach the height of kickboard 4, cursoryly just under molten steel buoyancy, rock floating, this moment, the operator was by the cursory timely control steel ladle slide board aperture of rocking, thereby avoided the molten steel 7 in the tundish 6 to overflow tundish overflow launder 4.
Claims (1)
1. demarcate the cursory of Metal in Tundish height for one kind, it is characterized in that, formed by crossbeam, connecting rod and kickboard; Be welded with a connecting rod in the middle of the crossbeam, connecting rod lower end welding kickboard.
