Some of the alloy was upgraded by blowing with oxygen in a top-blown rotary converter (TBRC), preferentially oxidizing the iron, and thereby concentrating the cobalt and copper in the alloy. The iron content in the alloy was lowered from 76 to 25%, with the effect that the alloy was concentrated up to 30% cobalt and 40% copper.

The method of autogenous production of crude lead from materials containing lead sulfide comprising the steps of . rotating at 10-60 r.p.m. a pre-heated top blown rotary converter on an axis inclined to the horizontal plane at a speed of 0.5-7 m/s measured at the inner periphery of the cylindrical part of the converter,

top-blown rotary converter References in periodicals archive ? For example, a five horsepower rotary converter costs approximately $500 versus $125 for a static unit, but one-third of the horsepower rating of the motor is lost with the static converter because you do not have all phases.

The portfolio of converter processes is widely spread and mainly depends on the specific requirements of the metallurgical process. The most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. We offer units such as Top Blown Rotary Converter (TBRC), Kaldo Converter, Peirce-Smith Converter as ...

Top Blown Rotary Converter Top Blown Rotary Converter. This converter operates in inclined position, which rotates about its horizontal axis for treatment of copper smelter anode slimes to recover precious metal content. These direct bonded Mag-Chrome bricks …

A Kaldo converter is a rotary vessel oxygen based metal refining method. Originally applied to the refining of iron into steel, with most installations in the 1960s, the process is used primarily to refine non ferrous metals, typically copper. In that field, it is often named …

Appendix G. Top Blown Rotary Converter Top blown rotary converters (TBRCs) (Figure G.1) are used to: (a) melt and oxidize (convert) Fe and S from granulated Pt-element-rich elec-tric furnace FeNiCuS matte in preparation for matte leaching/ …

Top Blown Rotary Converter (TBRC) The TBRC is a high-speed, rotating vessel fired by an oxy-fuel lances. Both the lancing technique and the rotation of the vessel provide remarkable augmentation in mass transfer rates compared with reverberatory or rotary furnaces. TBRC's can be used for smelting and refining in the same vessel.

In top-blown converters, the O2 is jetted at supersonic velocities with convergent divergent nozzles at the tip of the water cooled lance. A forceful gas jet penetrates the slag and impinges onto the surface of the liquid bath to refine the steel. Today most of the converters operate with lance tips containing 3 to 6 nozzles.

Top-blown rotary converter . 0.5 m O.D. tiltable rotating furnace (1500°C max) 120 kW oxygen-propane burner Control system The TBRC is a tilting, rotary furnace equipped with an oxygen-propane lance It has the following benefits: The rotation of the vessel improves heat transfer, and accelerates the reactions involved in refining and smelting ...

The process comprises the steps of charging the slimes into a tiltable and rotatable top blown rotary converter (TBRC), smelting the slimes in the TBRC while it is rotated on an axis inclined to the horizontal to form a slag phase and a precious metals containing phase, tilting the TBRC and skimming the slag produced during smelting, and ...

The system provides 12 parameters for massaging the data, which are accessed and adjusted on the control box, using a rotary encoder with a button underneath it, a second button, and a three-digit LED display. The parameters include MIDI channel, controller number, minimum and maximum output values, and data density.

The blast furnace and converter may be omitted from the process if average copper content of the scrap being used is greater than about 90 percent. The process used by one U.S. facility involves the use of a patented top-blown rotary converter in lieu of the blast, converting, and reverberatory furnaces and the electrolytic refining

The process is known as top-blown rotary converter. Air or air–oxygen mixture was blown through an inclined water-cooled lance onto the bath surface. Copper converting was performed as a batch process in two stages, slag blow and blister blow. The same converter could be used, principally, for matte smelting.

A rotary snowplow is operated by a pair of people ― the driver and the operator ― who are greatly respected as the operation requires a very high level of skill and experience. The operator uses seven or eight different levers to control the angle of the snow-removal unit and …

By injecting the oxygen directly into the bath, rather than blowing it on top (as in the case of the reverberatory cupellation furnace or top-blown rotary converters), the oxygen transfer efficiency is not impeded by the presence of the slag layer. It results in an oxygen utilization efficiency approaching .

These are the Noranda, TBRC (top-blown rotary converter), and Mitsubishi processes. The Noranda reactor is a horizontal cylindrical furnace with a depression in the centre where the metal collects and a raised hearth at one end where the slag is run off. Pelletized unroasted sulfide concentrate is poured into the molten bath at one end, where ...

The Kaldo type converted is commonly known as a Top-Blown Rotary Converter (TBRC) in non-ferrous metal smelting terminology. By the 1970s the Kaldo furnace was in common use for copper and nickel smelting. A Kaldo converter for the smelting of lead was constructed by Boliden in Sweden in 1976.
