Abstract
The invention discloses a copper melting and casting process, which comprises the steps of discharging, covering, melting and slag extraction, wherein covering refers to completely and uniformly covering molten and cast liquid copper with extruded and synthesized carbon particles. According to the copper melting and casting process, the flame-retardant synthesized carbon particles are used for covering in a copper machining melting and casting process, and are uniform and low in gap rate, so that an oxygen isolation effect can be effectively achieved; the flame-retardant synthesized carbon particles are uninflammable, so that production cost is effectively lowered, waste is reduced, the operating environment is improved, and environmental pollution is reduced.
Description
Technical field
The present invention relates to copper casting technology field, especially relate to a kind of copper founding.
Background technology
In copper level continuous casting melting furnace technique, usually adopt charcoal to cover, reach the effect of copper liquid oxygen barrier, improve the crystalline quality of casting in bronze base, reduce the oxygen content of casting in bronze base.
Existing exist following shortcoming by common charcoal technique for applying in copper level continuous casting melting furnace: 1, copper meeting in horizontal casting melting furnace fusion-casting process not exclusively makes because charcoal covers copper liquid contact with air and produces bubble, form oxide, and constantly need drag for slag, dragging in slag process, the exposed easily oxygen uptake outside of copper liquid, the crystallization of casting in bronze base is uneven, affects product quality; 2, traditional founding adopts common charcoal to cover it, although play oxygen barrier effect, because of easily conflagration under the copper liquid hot environment of charcoal more than 1000 DEG C, need constantly repeatedly add, cost is large; 3, a large amount of charcoal burning easily makes operating environment become severe, produces more discarded object, increases environmental pollution.
Summary of the invention
Not enough for prior art, technical problem to be solved by this invention is to provide a kind of copper founding, to reach reduction production cost, reduces the object of environmental pollution.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
This copper founding, comprises the following steps: blowing, covering, melting, drag for slag, and described covering adopts the complete uniform fold of extruding synthesis particle charcoal on the copper liquid of founding.
Further, described extruding synthesis particle charcoal is by carrying out sorting, fragmentation, screening, ball milling, extrudedly forming to charcoal.
Described extruding synthesis particle charcoal is cylinder particle.
Containing flame resistant material in described extruding synthesis particle charcoal.
Carry out curing processed after described extruding synthesis particle charcoal is extruded.
Described extruding synthesis particle charcoal length is 8-12mm, and diameter is 2-4mm.
The present invention compared with prior art, has the following advantages:
Utilize this resistance to combustion synthesis particle charcoal to cover in Copper fabrication fusion-casting process, the uniform particles of resistance to combustion synthesis particle charcoal, not easily produces gap, can effectively play oxygen barrier effect; Nonflammable, significantly reduce production cost, reduce discarded object, improve operating environment, reduce the pollution to environment.
Detailed description of the invention
By the description to embodiment, the specific embodiment of the present invention is described in further detail.
This copper founding, comprises the following steps: blowing, covering, melting, drag for slag; Thrown in smelting furnace by copper material, add extruding synthesis particle charcoal and cover, melting is carried out in heating, stirs and carries out dragging for slag, by waste scavenging, then is forwarded in holding furnace by copper liquid and carries out follow-up continuous casting process.
The complete uniform fold of extruding synthesis particle charcoal multilayer is on the copper liquid of founding.Extruding synthesis particle charcoal uniform particles, traditional normal wood carbon structure is formed different, is difficult to cover evenly, and extruding synthesis particle charcoal completely not easily produces gap because uniform particles contacts with copper liquid, effectively plays oxygen barrier effect.
Extruding synthesis particle carbon structure consolidation, loosen unlike normal wood carbon structure, burning is slow, and particle is little, can significantly reduce production cost, and the refuse amount of generation is few, reduces the pollution to environment.
Extruding synthesis particle charcoal is by carrying out sorting, fragmentation, screening, ball milling, extrudedly forming to industrial charcoal, extruded extruding synthesis particle carbon structure consolidation, carry out curing processed after extruding synthesis particle charcoal is extruded, prevent moisture in extruding synthesis particle charcoal from affecting copper liquid.
Containing flame resistant material in extruding synthesis particle charcoal, in mechanical milling process, add flame resistant material, flame resistant material can be the high temperature flame resistant materials such as silica.Further reduction extruding synthesis particle charcoal burning velocity, while effectively playing oxygen barrier, reduces costs, the refuse amount of less generation.
Extruding synthesis particle charcoal is cylinder particle; Extruding synthesis particle charcoal length is 8-12mm, and diameter is 2-4mm.Extruding synthesis particle charcoal is resistance to combustion synthesis particle charcoal, and uniform particles, not easily produces gap, can effectively play oxygen barrier effect.
Above to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
