Description

Schachtofen mit Herdtiegel und in diesem befindlichem rostähnlichem Gewölbe. Beim Schmelzen im Schachtofen ist es nicht immer möglich, einen Vorherd zum Sammeln des geschmolzenen Materials (Schlacke usw.) anzuwenden. Hat nun das Erschmolzene annähernd dasselbe spezifische Gewicht wie der Möller oder ist der Druck der Beschickungssäule im Schachtofen sehr groß, so trägt das geschmolzene Bad nicht das Ungeschmolzene, sondern wird sich nur in den Zwischenräumen der Beschickung ansammeln. Dadurch wird aber der glühende Koks allmählich vom Sauerstoff der eingeblasenen Luft abgeschnit# ten und verbrennt nicht weiter, sondern setzt sich als Ansatz im Herde fest, zumal der Koks ein schlechter Wärmeleiter ist. Durch die Ansätze wird also der Ofengang ein schlechter.Shaft furnace with hearth crucible and a rust-like material in it Vault. When melting in a shaft furnace, it is not always possible to use a forehearth to use to collect the molten material (slag, etc.). Now has that Melted approximately the same specific weight as the Möller or is the The pressure of the charging column in the shaft furnace is very high, so the molten material carries Bath not the unmelted, but only in the interstices of the loading accumulate. Through this but the glowing coke is gradually replaced by oxygen The blown air is cut off and does not continue to burn, but continues as a starting point in the hearth, especially since the coke is a poor conductor of heat. By the approaches so the oven aisle is a bad one.

Durch Einbau eines Rostes mit genügenden Öffnungen im Herdtiegel unterhalb des Schachtofens-unddarin liegt dasWesen der vorliegenden Erfindung - soll den vorstehend angedeuteten Nachteilen abgeholfen werden.By incorporating a grate with sufficient openings in the hearth of the shaft furnace crucible below-unddarin is dasWesen of the present invention - to mitigating the above-indicated disadvantages.

Die Erfindung ist in der Zeichnung schematisch dargestellt.The invention is shown schematically in the drawing.

a ist der Schachtofen, b der darunter befindliche bewegliche Herdtiegel, c der, Rost, der als ein rostähnliches Gewölbe gedacht ist, mit genügend Schlitzen oder öffnungen zum Durchlaufen der geschmolzenen Schlacke und zum Tragen der ungeschmolzenen Ofenbeschickung. a is the shaft furnace, b the movable hearth crucible underneath, c the grate, which is intended as a grate-like vault with enough slots or openings for the molten slag to pass through and to carry the unmelted furnace charge.

Im übrig-en ist die Ausführung des Rostes für,das Wesen der Erfindung belanglos, doch sei noch Nachstehendes erwähnt.What is left is the execution of the grate for, the essence of the invention irrelevant, but the following should be mentioned.

Als Material zu dem Rost können nur hochfeuerfeste Steine verwandt werden, und zwar wird man es dem Charakter der Schlacke anpassen, d. h. man wird für eine saure Schlacke eine starke Kieselsäure oder siliziumhaltiges Material, wie z. B. Carborundum verwenden, für basische Schlacken Steine aus elektrisch geschmolzenem Bauxit, reiner Ton-,erde oder Magnesit.As the material to the grate only highly refractory bricks can be used, and that it will adapt it to the nature of the slag, d. H. for an acidic slag, a strong silica or silicon-containing material, such as. B. use carborundum, for basic slag stones made of electrically fused bauxite, pure clay, earth or magnesite.

An Stelle des aus Steinen in Ziegelfonn hergestellten Rostes verwendet man auch Rostbalken in Röhrenform, um sie mittels Druckluft kühlen zu können und eine größere Haltbarkeit zu gewährleisten.Used in place of the grate made of stones in a brick mold one also grate bars in tubular shape to be able to cool them with compressed air and to ensure greater durability.
