Abstract
The utility model provides a tundish baking air inducing device, which consists of a top plate, a flue and an injection pipe; the middle of the flue with an arc shape is divided into a vertical section and a horizontal section, an injection pipe connected with a compressed air pipeline is inserted along the arc top of the horizontal section of the flue, the upper end of the vertical section of the flue is provided with a top disc, and the top disc is connected with an ignition brick at the bottom of the tundish. After the top plate is connected with the ignition brick and the injection pipe is connected with the compressed air pipe, the compressed air switch is turned on and the top baking cover is ignited, so that the tundish baking can be carried out. Because the air inducing device is additionally arranged, the high-temperature smoke flow passing through the stopper rod and the upper nozzle is increased, the baking effect of the head of the stopper rod and the upper nozzle is improved, the phenomena of local cold steel and liquid level fluctuation are avoided, the casting safety and reliability are improved, and the smooth casting of various steel grades is ensured.
Description
Technical field
The utility model belongs to the steelmaking equipment field, relates in particular to a kind of blower unit that is used for continuous casting tundish baking time control preparing high-temp flue gas flow direction.
Background technology
The continuous casting tundish must fully toast before use, reaches the intensity of regulation to guarantee the tundish refractory material, and guarantees that positions such as stopper, filling pipe end reach uniform temperature.In most of steel mills, the form that the tundish apparatus for baking is adopted is the top heated type, promptly be blown into fuel gas such as coal gas at the tundish top, adopt air-breathing, high-temperature flue gas is discharged by clad chimney, the slide mechanism brick of igniting, and wherein the flue gas of discharging from the brick of igniting has the function to stopper head and filling pipe end heating.
Find in the practical application, tundish that volume is bigger or continuous casting of two strands in parallel machine tundish are when baking, most high-temperature flue gas are often directly drained from chimney, flow through tundish bottom the brick place of igniting exhaust gas volumn seldom, stopper and filling pipe end position are in the tundish bottom side portion in addition, unfavorable to absorbing flame radiation heat, therefore cause stopper head and filling pipe end cured effect relatively poor, temperature does not reach the regulation requirement, Yin Qikai waters stopper head and the cold steel of the local knot of filling pipe end in the process, causes easily opening and waters difficulty, liquid fluctuating even cause the accidents such as watering failure of opening.Change above-mentioned condition most effectively way be to install air-introduced machine additional, but, and limited by field condition because the tundish flue-gas temperature is very high, can't increase unnecessary heat-exchanger rig, therefore should not use air-introduced machine, make problem fail effectively to be solved always.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple, and operation can effectively improve tundish stopper and filling pipe end cured effect easily, improves and opens the baking blower unit that waters security and reliability.
For this reason, the solution taked of the utility model is:
A kind of tundish baking blower unit, by take over a business, flue and induction tunnel form; The flue that the centre has an arc is divided into vertically and two sections of levels, along the arc tip cutting of flue horizontal segment an induction tunnel that is connected with compressed air piping is housed, and is provided with in the upper end of vertical section of flue, takes over a business the brick of igniting and be connected bottom tundish.
The beneficial effects of the utility model are:
After tundish entered the baking position, at first will take over a business and ignite brick and induction tunnel and compressed air hose be opened air pressure switch to the regulation flow again to connecting, and lighted top baking lid then, carried out the tundish baking.Baking is removed blower unit after finishing, and tundish is moved to the cast position get final product.Owing to set up blower unit in the tundish bottom, increased high-temperature flue gas flow by stopper and filling pipe end place, greatly improved the cured effect of stopper head and filling pipe end, make the interior temperature of tundish reach the baking temperature of regulation relatively equably, cold steel of local knot and liquid fluctuating phenomenon have been avoided, improved and opened the security and the reliability of watering, guaranteed that all kinds of steel grades open carrying out smoothly of watering.
Description of drawings
Fig. 1 is tundish baking blower unit structural representation.
Fig. 2 installs and uses view for tundish baking blower unit.
Among the figure: take over a business 1, flue 2, induction tunnel 3, tundish 4, the brick 5 of igniting
The specific embodiment
By accompanying drawing as seen, the tundish of the utility model baking blower unit mainly by take over a business 1, flue 2 and induction tunnel 3 formed.Flue 2 is divided into vertical section and horizontal segment two parts, vertically adopts arc-shaped transition between section and the horizontal segment, and promptly vertically section connects horizontal segment by the medial arc transition.Vertically be provided with a circular head plate 1 in the upper end of section at flue 2, take over a business 1 and be connected with the brick 5 of igniting of tundish 4 bottoms; Simultaneously, the transition arcs tip cutting of suitable flue 2 horizontal segments has an induction tunnel 3, and induction tunnel 3 one ends are inserted in flue 2 horizontal segments, and the other end is connected on the external compression air duct.
