Abstract
A combined furnace system for raw red copper fire refining sequentially comprises a shaft furnace, a raw red copper liquid flow channel, at least one rotary furnace and a refined copper liquid flow channel. The shaft furnace is used for smelting raw red copper materials into raw red copper liquid, and the rotary furnaces are used for producing refined copper liquid by means of oxidization and refining of the raw red copper liquid. The combined furnace system is characterized by further comprising a tilting furnace which is arranged between the shaft furnace and the raw red copper liquid flow channel and used for deslagging operation of raw red copper liquid containing slag. The combined furnace system for raw red copper fire refining is convenient in deslagging, guarantees smoothness of the raw red copper liquid flow channel and is stable in smelting and refining production efficiency.

Technical field
The utility model relates to a kind of combination stove system that is used for purple composition brass pyrorefining, is made up of 1 (cover) shaft furnace, 1 (cover) tilting furnace, at least 1 (cover) rotary kiln and copper spout, belongs to the non-ferrous metal metallurgy technical field.
Background technology
Purple composition brass is that copper content is not less than 90% copper scrap.Purple composition brass is purified through pyrorefining becomes refined matte.The higher refined matte liquid of purity is used for the continuous casting and rolling electrician with copper cash base (claiming copper bar, copper wire rod again), or other red copper base that is used to cast.The refined matte liquid that purity is not high is used to the positive plate of casting.
CN201713557U discloses a kind of combination stove system that is used for purple composition brass pyrorefining that is made up of 1 shaft furnace, at least 1 rotary kiln and copper spout, its basic procedure is purple composition brass charging machine → shaft furnace → purple composition brass spout → rotary refining furnace → refined matte spout → copper cash continuous-casting tandem-rolling production line or positive plate liquid filling machine.The subject matter of its existence is: when the junior purple composition brass of shaft furnace refining quality, can generate more slag, and this slag is put at shaft furnace and easily blocked in copper mouth, slag-drip opening and the purple composition brass spout, is difficult to remove, thereby has reduced production efficiency.
In the prior art, the precedent of shaft furnace, tilting furnace, rotary kiln three stove couplings never.
The utility model content
The purpose of this utility model provides a kind of combination stove system that is used for purple composition brass pyrorefining, even it is when the junior purple composition brass of shaft furnace refining quality, can not put the obstruction that is difficult to remove in copper mouth, slag-drip opening and the purple composition brass spout yet, thereby can guarantee that production efficiency does not descend at shaft furnace.
For this reason, the utility model provides a kind of combination stove system that is used for purple composition brass pyrorefining, and it comprises successively: a shaft furnace that purple composition brass raw material is smelted into purple composition brass liquid; One purple composition brass spout; Purple composition brass liquid is carried out at least one rotary kiln of redox refining output refined matte liquid; And a refined matte spout, it is characterized in that, between described shaft furnace and purple composition brass spout, also comprise a tilting furnace that is used for the purple composition brass liquid of slag inclusion is removed slag operation.
Preferably, comprise two or two cover rotary kilns.
Preferably, comprise three or three cover rotary kilns.
Preferably, purple composition brass spout or refined matte spout are movable, fixed or movable and fixed combinations;
Preferably, each purple composition brass spout or refined matte spout chute are one or more snippets.
Preferably, the downstream of refined matte spout is connected with copper cash continuous-casting tandem-rolling production line or positive plate is cast into complete equipment, and copper cash continuous-casting tandem-rolling production line or positive plate liquid filling machine comprise corollary apparatus such as its preposition holding furnace, tundish, quantitative casting bag, copper spout.
Basic procedure of the present utility model is purple composition brass charging machine → shaft furnace → tilting furnace → purple composition brass spout → rotary refining furnace → refined matte spout → copper cash continuous-casting tandem-rolling production line or positive plate liquid filling machine.Therefore, the utility model is that the improvement at existing pyrorefining system is, increases the convenient tilting furnace that removes the gred of a cover between the shaft furnace of this pyrorefining system and purple composition brass spout.
The beneficial effects of the utility model are to provide a kind of and removed the gred conveniently, guarantee that purple composition brass spout is unimpeded, the stable combination stove system of fusing refining production efficiency.
Description of drawings
Fig. 1 is the synoptic diagram according to purple composition brass pyrorefining of the present utility model system.
Embodiment
In Fig. 1, Reference numeral 1 expression charging machine; Reference numeral 2 expression shaft furnaces; Reference numeral 3 expression tilting furnaces; The purple composition brass spout of Reference numeral 4 expressions; Two rotary kilns of Reference numeral 5 expressions; Reference numeral 6 expression refined matte spouts; Reference numeral 7 expression copper cash continuous-casting tandem-rolling production line or positive plate liquid filling machine.Pack into the charging machine 1 of truck formula or other form of purple composition brass raw material, add shaft furnace 2 thereupon; The shaft furnace melting batch, the purple composition brass liquid of output and a small amount of slag; The purple composition brass liquid of slag inclusion removes slag operation at tilting furnace 3; Purple composition brass liquid is carried through chute 4, enters the whole process that 5, two rotary kilns 5 of two rotary kilns are independently finished refinery process separately; The refined matte liquid of rotary kiln 5 outputs is carried through chute 6, enters the tundish (casting ladle) of copper cash continuous casting and rolling production line or positive plate liquid filling machine 7, is used for continuous casting and rolling copper cash base or casting positive plate.
To produce 240000 tons of engineerings of copper cash base per year is example, and technical process is as follows:
1. the purple composition brass raw material of pre-treatment is removed inclusion as far as possible, and processing length or lumpiness should be fit to the truck of packing into.
2. with fork truck the purple composition brass raw material truck formula charging machine of packing into.
3. truck formula charging machine adds production capacity 40t/h shaft furnace to purple composition brass furnace charge.
4. shaft furnace melting batch, the purple composition brass liquid of output and a small amount of slag continuously.
5. the purple composition brass liquid of slag inclusion flows into capacity 50t tilting furnace, removes slag operation.
6. purple composition brass liquid is carried through chute, is taken up in order of priority and introduces two capacity 200t rotary kilns.
7. two nominal capacity 200t rotary kilns are independently finished separately and are accessed copper liquid, oxidation, deslagging, reduction, controlled temperature and composition, copper operation whole process, but interlaced 1/2 operation process of while.When being about to out copper liquid for one, another begins copper, steadily alternately, keeps the flow of refined matte spout basicly stable.
8. the refined matte liquid of rotary kiln output enters the tundish of production capacity 40t/h continuous casting and rolling production line by chute, through continuous billet casting, rolling, and output copper cash base.
