CONVERTER.

Specification of Letters Patent.

Patented oct. 11, 1910.

To all whom it may concern.'

Be it known that we, WILLIAM J. MURPHY and ALBERT E. CULLEY, both citizens of the United States7 residing in Butte, county of Silverbow, and State of Montana, have invented certain new and useful Improve- Aments in Converters, of which the following y rapidly-.attackthis lining so that it must be renewed after a comparatively small number of' charges have been operated upon. This is especially true Where sullid ores of copper are worked upon', since it is necessary that some fluxing material be provided so that the, impurities in the ore may combine with the l'luX to form a fusible slag. In such cases the impurities in the charge will combine with the lining toform the slag.

The objects of this invention are there.

fore to so construct and operate a converter that its lining will be protected against the destructive action of the charge.

The invention will be described in connection withthb accompanying drawings in which,

Figure 1. is a front elevation showing an 35 jripparatus for carrying on this invention.

4ig. 2. is a sedtion on line 2 2 Fig. 1, parts being shown in elevation, Fig. 3. is a longitudinal vertical section, and Fig. 4. is a section on line 4 4 Fig. 3.

The converter comprises a cylindrical shell l0 lined with a suitable refractory linin and mounted for tiltin movement on ro 1ers 11. The converter is tilted in the usual manner by means of a motor 12 provided with a rack 13 engaging a pinion 14 on the cylinder. The air is supplied from a supply pipe 15 to the wind box 16 and from there distributed to the twyers 17. The construction so far described is well known.

The converter is provided with removable cap 18 which is bolted thereon andathroat or stack 19 is located at one end of the cap. Thecap like the body is provided with a refractory lining and the converter is further provided with a'tap hole 20y and a spout so that the charge may be tapped. lt will be understood that during the converting operation the tap hole will be closed by means of a suitable plug.

The walls of the converter areprovided with conduits or passages 21 which extend through the walls and into the interiori rl',`hese conduits or passages are preferably located at the ends and incline downwardly as shown, and are provided with filling hoppers 22. The inner wall of the converter has formed thereon a rib 23, and the wall eX- tends rearwardly from the rib toward the ends; these ends are preferably rounded as shown for a purpose hereinafter t0 be described.

A. fluxing material in a divided-or granular condition is supplied to the hoppers 22 and introduced into the converter, and this iuxing material is spread on the bottom and banked against the walls as shown in Fig. 3. The charge'is now introduced and the blast turned on.,l During this operation the lcharge will feedfupon fluxing material in preference to feeding upon the lining of the .converter. The hopp'ers are constantly kept tilledso that an excess of fluxing material is constantly presentand this material will be introduced into the converter against the end walls so as to form a protective lining as shown in Fig. 3. The banking of the HuXing material against the walls is facilitated due to the fact that conduits 22 incline downwardly. The blast will cause the charge to be blown against the wall opposite that which the twyers are located, and the molten' charge will strike the rib 23 and will be divided and directed and deflected against the fluxing material at the end walls. The charge will thus be given a movement against the fluxing material so as to thoroughly come in cont-act with the same, and the rounded construction of the ends will cause the metal to be given a rotative movement right andl left thereby further facilitatiug the operation. It will thus be seen that this invention provides means whereby the converter' will be made self-lining. The character of the uXing material Will de pend upon the character of the ore worked upon. For coppei` ores containing iron and suliids a silica flux will be used. In all cases however, the flux is introduced into the converter so that the charge will act upon itin preference to the 'lining'. This invention thereby provides means whereby of charges without necessitating relining.

The fluxing material may be introduced directly into hoppers 22 with shovels or in any othersuitable` manner. In order that this material may be conveniently introduced a pair o f supply hoppers 24 are mounted upon a frame 25 and pipes 26 extend from these hoppers over the hoppers 22. Each of the hoppers 24 is provided with a feed slide QZ operated by a handle 28. This provides a very convenient arrangement for introducing fluxing material and also permits free movement of -the converter.

It will be noted that the converter is cylindrical in section throughout its entire length as distinguished from converters now in use Ain which the interior tapers from the bottomto the centrally located throat. The' removable cap 18 permits easy inspection of the converter and also facilitates relining when necessary. By placing the stack l 19 Aat the end of the converter and by making the interior cylindrical, splashing of theJ metal is prevented, thus minimizing the danger to the operator.

It is obvious that various changesr may be made in the details of the ap aratus without departing from the spirit o this invention, and itis therefore to be understood that this invention is not to be limitedto the specific arrangements shown and described. i

Having thus described the invention, what is claimed is:

1. The combination in a converter havin walls,`of flux conduits extending into said converter, and constructed to introduce a Huizing materialinto the converter and to deliver the saine against said walls to form aprotective lining therefor.

2. The combination in a converter having walls, of means for introducing a iuxing material into the conif'rterA and for delivering the same .against said walls to form a protectivel lining therefor, and means for directing. the charge against the' luxing ma'- Y teria] so introduced.

3. The combination in a converter havin walls, of means whereby a luxing materia may be introduced intol the converter andv against said walls, and means! for directi the charge against that portion of the Wal which is coveredrby the fluxing material.

4. The combination in a converter having walls', and twyersfor introducing a blast to agitate the charge, of means whereby a iiuxing materialv may be introducedinlto'the 1 converter and deposited against some of J said walls, and a deecting rib on one of said walls ciinstr'ucted to direct the agitated v 'chgrgle against the fluxing material.
