Description

Uppfinnare: H J W Tiefenthal Prioritet begord [ran den 1 lard 1962 (Forbundsrepubliken Tyskland) Konvertrar for stalframstallning besta. som bekant av i stort sett cylindriska bchallare, som emellertid avsmalna upptill, sa att det är risk for att i den lutande delen av infodringen lossnande delar av den eldfasta massan falla bort. Om delta sker nar arbeten utforas i konvertern, t. ex. vid nybekladnad, kan arbetaren skadas av de nedfallande delarna. FOreliggande uppfinning avser att eliminera denna risk. Inventor: H J W Tiefenthal Priority requested [ran 1 lard 1962 (Federal Republic of Germany) Converters for steel production exist. as is known from substantially cylindrical bchallars, which, however, taper at the top, said that there is a risk that parts of the refractory mass detaching in the inclined part of the lining will fall off. If delta occurs when the work is performed in the converter, e.g. when freshly dressed, the worker can be injured by the falling parts. The present invention seeks to eliminate this risk.

Uppfinningen bestar i enlighet claimed av en anordning, som i huvudsak bestax av en uppblasbar, flexibel halkropp, som efter uppblaming anligger mot behallarvdggen och forhindrar nedfallande av stone delar. The invention consists in accordance with the claimed device with a device which essentially consists of an inflatable, flexible hollow body which, after inflation, abuts against the container wall and prevents falling of stone parts.

Pa ritningen visas i tvarsnitt ett utforingsexempel pa uppfinningen. The drawing shows in cross section an embodiment of the invention.

Konverterbehallaren bestar i huvudsak av platmanteln 1 och den eldfasta infodringen 2. Enar konverterbehallaren vid Overdelen smalnar uppat, uppvisar den i denna del, som har formen av en stympad kon, en Overhangande vagg 3. For att forhindra nedfallandet av delar frau. den Overhangande vaggen 3 anbringas en efter den koniska Overdelen av konverterbehallaren anpassad, som en konisk ring formad, uppblasbar halkropp 4 i behallaren och uppblases dar. Vid uppblasningen av ringen lagger sig denna fast mot den Overhangande konvertervaggen 3 och forhindrar nedfallandet av delar av den eldfasta inkladnaden. Uppblasningen utfores medelst en slang 5, i vilken en tryckregleringsventil 6 är anordnad. Kroppen 4 är upphangd i en stel ring 7, som i sin tur hanger i en lina 8 och är hoj- och sankbar. Sedan luften slappts ut genom slangen 5 sjunker kroppen 4 ihop. Delta underlattas medelst kedjor 9, som aro an ordnade vid undersidan av kroppen 4. Sedan kroppen 4 Joints intager den ungefar det med streckprickade linjer antydda ldget 4' och kedjorna 9 laget 9'. Kroppen 4 kan sedan hissas upp genom konvertermynningen 10. The converter container mainly consists of the plate jacket 1 and the refractory lining 2. If the converter container at the upper part narrows upwards, it has in this part, which has the shape of a truncated cone, an overhanging cradle 3. To prevent the falling of parts frau. the Overhanging cradle 3 is fitted with an inflatable hollow body 4 adapted to the conical upper part of the converter container, shaped like a conical ring, and inflated there. When the ring is inflated, it attaches to the Overhanging converter cradle 3 and prevents the falling of parts of the refractory charge. The inflation is performed by means of a hose 5, in which a pressure control valve 6 is arranged. The body 4 is suspended in a rigid ring 7, which in turn hangs in a rope 8 and can be raised and lowered. After the air has been released through the hose 5, the body 4 collapses. Delta is facilitated by means of chains 9, which are arranged at the underside of the body 4. Since the body 4 Joints, it occupies approximately the line 4 'indicated by dash-dotted lines and the chains 9 team 9'. The body 4 can then be hoisted up through the converter orifice 10.

Den uppblasbara kroppen 4 kan besta av en dubbelvaggig textilmantel eller ocksa av plast eller annat lampligt material. The inflatable body 4 may consist of a double-walled textile jacket or also of plastic or other suitable material.

I stand fOr kedjor 9 kunna andra organ anvandas for att tynga underdelen pa kroppen 4. In the case of chains 9, other means can be used to weigh the lower part on the body 4.

Foreliggande anordning lampar sig icke blott for konvertrar utan kan anvandas Over-alit ddr arbeten utforas i en infodrad behallare, dar det är risk for att delar i infodringen falla ned och skada arbetaren. The present device is not only suitable for converters but can be used over-alit when the work is carried out in a lined container, where there is a risk of parts of the lining falling down and injuring the worker.

Claims

Patent claim:

1. Protective device when performing work in containers, e.g. Converters which are provided with a masonry or stamped liner, characterized in that it consists of an inflatable, flexible sliding body which, in the inflated state, abuts against the container cradle.

Device according to claim 1, characterized in that the inflatable body has the shape of a ring, e.g. with truncated conical shape.

Device according to claim 2, characterized in that the inflatable body is weighted at its lower spirit. Cited publications:
