Description

Pivoting furnace with vertical shaft and horizontal gas-heated Stove. The present invention relates to a furnace for smelting - # - of iron and Metals. The same belongs to the class of furnaces, in which the good to be melted is made from a vertical shaft to the associated horizontal hearth by the action of Flames slowly slide down.

With these ovens, the aim is to keep the flames in a certain Way to conduct in the hearth; in them the flame leads a whirling motion or is diverted around the material to be melted in the shaft.

The subject matter at hand differs from these institutions Invention by the fact that the flames, be it for quick melting, for bare Keeping the river bath hot, for oxidizing or reducing or cleaning by means of a Slide between the shaft and Stove is arranged horizontally.

With this slide the opening for the exhaust of the combustion gases can be opened set accordingly and move from one side to the opposite side. This possibility is of the utmost importance when purifying the river bath.

For example, the flame can be used for oxidation or reaction effects the required time in the oven until it is fully used give the slide lightly. On the other hand, you can use the flame for just keeping it hot of the melted material by relocating the exhaust opening to the opposite side a short distance away, the flame not touching the bath. This is special This is important because it is difficult to produce a neutral flame. The exploitation the products of combustion and the production of high quality metal is more perfect than with ovens in which the flame paths cannot be relocated at will.

The drawing shows an example of such a furnace.

i is the vertical shaft,: 2 the collecting space; 3 are the bearings with which the furnace is suspended from a frame or a ceiling. 4 is the fixed gas line, while 5 means the air supply line, which is also firmly connected to the building or the like. 6 is the winch with which the furnace can be swiveled until the slag or the metal runs out of the channel 7 . When the furnace is pivoted, the gas and air nozzles 8 and 9 pull themselves out of the sleeves of their lines 4 and 5 and, when the furnace goes back, press themselves back into the sleeves and seal automatically. By appropriately arranged shut-off means, gas and air can be throttled or shut off. The metal to be melted is fed into the shaft i through the door io, a larger passage to the collecting space 2 having previously been created by moving the slide ii by means of a rod through a small opening 13. The gas flames come from the ceiling of the collecting space, from the highest point äus the nozzles at 8, hit the melting material in a large area, work their way through the slider gap and then preheat the air in the preheater 12. Only after melting down is the dwell time of the combustion gases in the collecting space for the intended purification or for simply keeping warm by setting the slide ii.
