Abstract
The utility model discloses a device for producing low-oxygen bright copper pipes by scrap copper through continuous casting and continuous milling. The device consists of a scrap copper smelting vertical furnace, wherein a feeding opening is arranged above the vertical furnace, a hearth is arranged in the vertical furnace, scrap copper raw materials are placed into the hearth, the lower part of the vertical furnace is provided with a natural gas inlet and an oxygen blowing opening, an upper flow groove is also arranged under the vertical furnace and is connected with an insulation furnace used for reduction refining, the heat insulation furnace is connected with a lower flow groove, and the lower flowing groove is connected with casting equipment. The device is applicable to the recycling of the scrap copper.
Description
Technical field
The elegant novel a kind of copper smelting furnace that relates to of this reality especially relates to the device that a kind of scrap copper continuous casting and rolling is produced the low-oxygen bright copper pipe.
Background technology
Along with national economy is fast-developing, on the one hand, copper consumption rapid growth copper valency soars, and China's copper resource scarcity, copper ore concentrates output is difficult to satisfy the demands; On the other hand, waste household appliances, waste and old cable also increase rapidly in recent years, and cause environmental pollution.So, be China's coppersmith fast-developing shortcut that remedies already that there is lack of raw materials to the recycling of useless composition brass.For a long time, various countries' copper bar manufacturer is trying every possible means to improve copper scrap ratio in the starting material always.How to utilize copper scrap, technology scrap stock, adopt the scrap copper continuous casting and rolling low oxygen glitter copper lever manufacture craft of shaft furnace refinery practice, this is technician's a research target.
Summary of the invention
The purpose of the utility model is to the needs of above-mentioned useless composition brass recycling a kind of save energy to be provided, and the scrap copper continuous casting and rolling that ensure the quality of products, recovering effect is good is produced the device of low-oxygen bright copper pipe.
In order to achieve the above object, the utility model mainly adopts following technical scheme to realize.The utility model mainly is made up of useless composition brass melting shaft furnace, above shaft furnace, is provided with dog-house, is provided with burner hearth in the shaft furnace; Useless composition brass raw material places in the burner hearth; The bottom of shaft furnace is provided with Sweet natural gas import and oxygen blast mouth, also is being provided with chute below the shaft furnace, and last chute connects the holding furnace that is used for reduction refining; Holding furnace connects down tank, and down tank connects pourer.
The utility model compared with prior art has the following advantages.(1) this continuous casting and rolling production equipment is compared with traditional hot rolling method, has length length, saves the energy, constant product quality, performance homogeneous, characteristics such as surface-brightening.(2) traditional hot rolls, to the line bar, consume fuel oil 130Kg/t (being equivalent to heat energy 1300Mka/t) electric power 180Kwh/t adds up to consume heat energy 3023Mka/t by electrolytic copper.And the utility model only consumes 806Mka/t; (3) electric conductivity is high than traditional black bar (refer to that surface oxidation is severe, claim black bar) for the electric conductivity of the product of the utility model light bar, because black bar oxygen level is high.(4) black bar circle is heavy little, generally have only about 80Kg, and bright bar of the present invention is generally at 3-5t, so joint is few during wire drawing.Black bar needs pickling or strips off the skin, and three-waste pollution is arranged, and bright bar of the present invention does not need acid rinsing and strips off the skin, and does not pollute.
The utility model is applicable to the recycling of useless composition brass.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model one-piece construction synoptic diagram.
Embodiment
As shown in the figure, the utility model mainly is made up of 1 of useless composition brass melting shaft furnace, above shaft furnace 1, is provided with dog-house 5; Be provided with burner hearth 3 in the shaft furnace 1, useless composition brass raw material puts 2 in burner hearth 3, and the bottom of shaft furnace 1 is provided with Sweet natural gas import 6 and oxygen blast mouth 4; Also be provided with chute 7 below the shaft furnace 1; Last chute 7 connects the holding furnace 8 that is used for reduction refining, and holding furnace 8 connects down tank 9, and down tank 9 connects pourer.
The utility model is applicable to the recycling of useless composition brass.
