Description

Device for performing work in a metallurgical container.

[0001] The invention relates to a device for carrying out work under the effect of heat in a metallurgical container, comprising a mobile support device in the area of the furnace platform or the work platform with a telescopic arm that can oscillate in the support device or similar rotating arm and a working means that can be introduced with it into the metallurgical vessel.

[0002] In the internal space of a metallurgical container, such as furnace or converter, multiple measurement work as well as masonry repair as well as a breakage of the slag crusts and / or must be carried out during a kiln cycle be carried out with respect to loads temperature measurements of metal melts, sample extraction, introduction of sealing means, winding of alloy wires and the like.

[0003] A measurement of the masonry is performed multiple times even by the trained eye of an operator, after which a fire-retardant material can be applied in a directed way by means of work, especially spray nozzles, in areas of wear of the kiln wall .

[0004] It is known, for example from DE 363 90 83 A1, to use a robot for the improvement of the coating of melting furnaces by applying coating material under the heat effect of the melting furnace.

[0005] Devices of this type can be fixed in a stable manner with their support construction in the furnace area or they can be scrolled on a car in the furnace platform or work platform (document GB 1 592 360), driving a mobile swivel arm the working medium.

[0006] From UA 19 881 U it has been known, for example, a device that can be moved on the furnace platform for an introduction of a spike closure in a converter vessel by means of a telescopic arm.

[0007] US 4 478 392 also describes a closing means for a converter's bevel, the telescopic device being fixed in the construction of ships.

[0008] From DE10216172A1 a device is known for measuring the internal surface of a metallurgical fusion vessel, as well as for applying a flame retardant material on wall and base areas thereof.

[0009] Document US2001 / 0045691A1 discloses a mobile or movable multi-purpose unit for renovating the refractory masonry of a metal metallurgical converter's spout, with a drilling means connected with this unit, and the drilling medium can be exchanged for a installation medium for the lining of the board.

[0010] In a technical way of work it is essentially advantageous to provide, according to the possibility, a free work platform for the operative personnel and to place on the periphery, where possible, the support devices of the respective devices for the special mechanized works in the metallurgical vessel

[0011] Also in the case of the highest possible use of the space conditions given in the work platform area and of a low-volume construction, technical and economic inconveniences are associated with a plurality of devices for performing specific jobs under the effect of heat in a metallurgical vessel.

[0012] In this case, the invention aims to provide a remedy and set a goal to create a prior art device that in the case of reduced space in many embodiments of the support device can perform a plurality of work in a controlled manner in a container metallurgical.

[0013] This objective is solved by a device according to claim 1.

[0014] The advantages achieved with the invention must be observed essentially in that with a single support device a plurality of mechanized functions necessary in a metallurgical vessel can be performed.

[0015] Due to thermal radiation, parts of the telescopic arm support device and / or the working medium may be protected or cooled, especially cooled with water or air.

[0016] If, for example, it is established in the operation of the furnace or converter by means of a measurement, the measuring device can be displaced in the working medium in the container, where at points of the internal wall there are cavities due to wear, the working means according to the invention be provided in a simple manner according to the invention with a spray nozzle for the flame retardant material and introduced into the internal space of the container, after which the function of an extension or improvement of the wall guided by the objective is carried out in a controlled manner end by turning or oscillating the spray nozzle. After a subsequent loading of the metallurgical vessel, metallurgical work can be tested in this function medium which can be fixed according to the invention in the working medium for measurements of the temperature of the melt and / or slag, for sample extraction and the like.

[0017] A follow-up of the slag in case of bleeding of the fluid metal can be prevented with the device according to the invention, so that in the working means a sealing means for the runner is introduced so that it can be removed and so fixed with the telescopic arm in the metallurgical vessel and placed above the indentation and at a given time an unlocking of the fixation is performed.

[0018] In an improvement of the invention with a high degree of mechanization of the device, it can be provided favorably that function means provided in the area of the furnace platform can be fixed, possibly in a tank, with at least one joining device or of subjection to the means of work and can move with this and can withdraw again of this.

[0019] For the equipment of the working medium with function means, a mobile device can also be advantageously used, for example a tank with revolver lathe, possibly in a mobile way to promote the development of the fixation.

[0020] It is envisaged that the working medium will have more than two means of function and specifically devices for

-

measure the internal surface of the metallurgical vessel

-

apply, especially spread a fire retardant material in wall and base areas

-

measure the temperature of the melt and / or the slag and / or the walls

-

collect samples

-

introduce a sealing means for the runner

-

reduce slag scabs and the like and / or may be bonded with such as well as removed from them.

[0021] The invention will be explained in more detail below by means of a drawing that represents only one embodiment.

[0022] The list of reference numbers indicated below will facilitate the joint vision in relation to the functional parts of the device.
