Description
On draw the molten copper heat-preserving equipment of oxygen-free copper bar fuel oil (gas) holding furnace system, relating to fuel oil (gas) is the molten copper attemperator of fuel.
According to the knowledge of the applicant, smelting furnace and the holding furnace in continuous up-casting copper cash, copper bar, the copper pipe equipment all is thermal source with the frequency cored induction furnace at present, and it is compared with the resistance-type electric furnace, its thermoelectrical efficiency height, easy to maintenance.But power consumption is still high, and the product of 1 ton of copper of every production needs 700 degree electric energy approximately.In addition,, also need dispose high-rating generator,, thereby increase the amount of investment of equipment as emergency service in order to prevent to cut off the power supply in the fusion process; The electric furnace channel is disconnected easily, and maintenance difficulty is big, expense is high; Be restricted in the use of the area of supply of electric power deficiency, this also is the defective that is difficult to overcome.Thereby having caused design is the conception of the holding furnace of the energy with non-electric heating.In order to check the novelty of this conception, the applicant once retrieved the production of metal manufacturing, metal and the patent documentation in refining techniques field, retrieve relevant background technology and reach 240 remainders, and wherein comparatively close technological project carried out studying repeatedly and comparing, as " low pressure casting power frequency induction holding furnace " (applying date: 85.7.1, notification number: CN85202709U); " continuous up-casting machine " (applying date: 89.4.12, application number: 89205523.5); " a kind of multi-piece horizontally continuous casting device " (applying date: 92.11.11, publication number: CN1086752A); " continuous casting fusing, holding furnace " (applying date: 91.6.8, notification number CN2103389U); " internal heat type induction furnace " (applying date: 96.3.30, notification number: CN2255599Y) or the like; Be the electromagnetic induction furnace that is used for non-ferrous metal metallurgy.These have just illustrated, are not that the technical scheme of the molten copper holding furnace of the energy proposed patent application to Patent Office of the People's Republic of China with fuel oil (gas) as yet till up to now, also do not have similar technology known public for the public.
The design the purpose of this utility model is: seeking a kind of be the molten copper holding furnace of the energy with fuel oil (gas), to eliminate in the molten copper production process the dependence of electric energy, reduces total investment of engineering, the maintenance cost of reduction equipment and the cost of product.
On to draw the claimed technical scheme of oxygen-free copper bar fuel oil (gas) holding furnace as follows: the crucible that the utility model adopted, holding furnace material, crystallizer, oil spout (gas) are though mouth, hauling machine, continuous up-casting machine are public device, but structurally taked following method for designing: holding furnace (5) is for cylindrical, constitute by refractory material, crucible (1) embeds in it, " bucket " shape of the big up and small down formula of crucible, the bottom of crucible (1) are placed on the pillar (4); Outer periphery in crucible (1) below is provided with combustion chamber (3) with the bottom of holding furnace (5); In the combustion chamber, be provided with the oil spout (gas) mouthful (2) that is connected with fuel oil (gas) pipeline; Establishing crystallizer (10) in crucible (1), it is placed in the copper liquid; Directly over crystallizer (10), the part machine (9) that leads is housed, it connects with continuous up-casting machine equipment (13); On draw copper bar (8) and link to each other with hauling machine (9) through crystallizer (10).Offer in the top of crucible (1) and to add copper liquid poor (11).Below holding furnace, offer safe mouthful (12), constitute combustion chamber (3) and outside passage.In the bottom of holding furnace (5) movable wheel (6) is installed, it is placed on the platform (14).In crucible, place thermocouple (7).
Refer again to accompanying drawing below also in conjunction with the embodiments, the technical program be further described:
Accompanying drawing is the structural representation that draws oxygen-free copper bar fuel oil (gas) holding furnace, among the figure: 1---crucible, " bucket " shape of big up and small down formula is adopted the 700# crucible here, and it is embedded in the holding furnace that is made of refractory material.2---oil spout (gas) mouth, be located in the combustion chamber, be connected with fuel oil (gas) pipeline, and the flow of oil (gas) regulated by it.3---combustion chamber, the space between the periphery of crucible periphery and holding furnace liner, furnace bottom.4---support column, crucible (1) is placed in directly over it.5---holding furnace is outward cylindrical, profile chi Φ 1200mm * 1200mm, inwall is round bucket shape, is built into by high-alumina brick.6---the movable wheel, be installed in the bottom surface of holding furnace (5), place on the platform (14), removable, easy access.7---electroheat pair, be used to measure the temperature of copper liquid, by the platinum rhodium---platinum is made, can measure temperature scope 0-1300 ℃.8---on draw the copper bar, in the present embodiment, have and draw the copper bar on 4, its lower end is equipped with graphite mo(u)ld respectively, is sleeved on 10 centimetres of depths of inserting copper liquid in 4 crystallizers in the lump.9---hauling machine, to go up gorgeous copper bar (8) and link to each other with hauling machine through crystallizer, its effect is drawn the copper bar on being, and controls its speed.10---crystallizer, the 4-6 root is given copper bar cooling shaping, makes copper bar surface be in the vacuum crystallization state.11---it is poor to add copper liquid, is arranged on the top of crucible (1), injects copper liquid through this groove to crucible.12---safety mouthful, be positioned at the below of holding furnace (5), be logical combustion chamber (3) of structure and outside passage.13---the continuous up-casting machine equipment is public outsourcing corollary equipment.14---platform, the supporting surface of formation activity wheel (6).
The course of work of drawing oxygen-free copper bar fuel oil (gas) holding furnace on this is as follows: with charcoal crucible (1) is warmed, approximately to 500 ℃, again by oil spout (gas) mouthful oil spout (gas), make the furnace bottom of holding furnace (5), furnace wall, crucible (1) continue to be heated to 950 ℃, [thermocouple (7) is inserted thermometric in the crucible]; To melt the copper liquid that has melted in the copper crucible stove (, not drawing in the accompanying drawings) and join in the crucible (1) of holding furnace, make it the liquation amount that reaches certain because of belonging to molten copper device; Method with oil spout is carried out temperature control to holding furnace and crucible, and the temperature of copper liquid is risen in 1130-1170 ℃ the scope; Can on draw the copper bar, lead speed is the 400-450mm/ branch, can on draw the 4-6 root, its diameter is 14.4mm.
Compare with now general commercial frequency cored induction furnace, the utlity model has following beneficial effect: the gross investment of (1) main frequency furnace (contains leading-in device, generator, converting equipment) about 500,000 yuan, and only need 250,000 yuan by the described equipment investment of the technical program, but investment-saving 50%.(2) impurity of copper easy-clear not in the production process of main frequency furnace, and this device easy-clear copper ashes, feasible refining.(3) main frequency furnace is produced the energy consumption of copper per ton and is 700 degree electricity/tons, and is electric by 1 yuan as every degree, and then 700 yuan, and this installs 200 kilograms of No. 0 diesel oil of consumption per ton, by 1 yuan of per kilogram, then a need is 200 yuan.When (4) main frequency furnace had a power failure, needing transmits electricity in addition was incubated, and the influence that this device is not had a power failure.(5) cost of overhaul of main frequency furnace is more than about ten thousand yuan, and the maintenance cost of this machine only needs 2,000 yuan, can economize expense 80%.(6) the power frequency holding furnace heating-up time needs 96 hours approximately, power consumption 8000 degree, and this machine then needs 8 hours, 136 kilograms of oil consumptions.(7) main frequency furnace need be a raw material with special red copper, and this device only needs purple composition brass to get final product.
