Abstract
The invention discloses a profile machining process of Yunnan variegated-copperware. The process comprises the following steps: (1) smelting: T1 electrolytic copper is selected as a raw material, and is smelted to molten copper; a molten copper covering agent covers the molten copper; the smelting temperature is 1050-11000 DEG C; and the smelting time is 3-4 h; (2) casting of a copper ingot: before the molten copper is cast, a deoxidizing agent of phosphorus and rice bran are added; the molten copper covering agent is added in a crystallizer; the casting temperature is 1150-12000 DEG C; the casting speed is 4-11 m/h; and the amount of cooling water is 20-55 m3/h; and (3) heating and forging: (1) a forging blank is machined; (2) a forging is discharged; and (3) a forging process: the heating temperature is 820-8500 DEG C; forging: the upsetting, the punching and the chambering are performed to reach the forging size of an end ring; the forging is put in water for cooling after the forging is finished; the cooling temperature is 50-700 DEG C; the cooling time is 0.5-1.5 h; and then, the rolling formation is performed to obtain the variegated-copperware with higher purity.
Description
Technical field
The present invention relates to spot Copper fabrication field, be specially the section bar processing technology of mettled copper of Yunnan Province.
Background technology
Spot copper is the distinctive folk traditional craft product in Yunnan, has more than 300 year history so far.Plaque copper skill makes complicated and strict, adopt high-grade acid bronze alloy raw material, through casting, Seiko is polished, and the rear PROCESS FOR TREATMENT of complexity make with become it " wonderful having spot, be valued for simple and honest ", the surface presentation of maroon goes out odd flicker, gorgeous mottled, change delicate spot flower and take the course of its own, can be rated as the hat of smithcraft.Because spot copper needs to adopt high-grade high-quality tough-pitch copper as raw material, and be difficult to now the natural pig copper that finds copper content more than 90%, simultaneously, forge dozen spot copper by hand to produce on a large scale as batch casting, even make the bornite handicraft that piggy is very little like this, also need the time of a couple of months, this directly causes the rareness of spot copper finished product.Adding spot copper is complete manual making, and each artist has oneself " originality ", and every part works are all unique, and therefore, Huize is forged and beaten spot copper and have quite high appreciation and reserve value.
Spot Copper fabrication process costs conventional is at present higher, and outward appearance is attractive in appearance not.
Summary of the invention
The object of the invention is the section bar processing technology in order to provide mettled copper of Yunnan Province, to solve the problem proposed in above-mentioned background technology.
In order to achieve the above object, the present invention realizes by the following technical solutions:
The section bar processing technology of mettled copper of Yunnan Province, comprises the following steps:
(1), melting: raw material selection T1 cathode copper through being smelted into copper liquid, covering copper liquid coverture in copper liquid; Fusing temperature is: 1050-1100 0C; Fusing time is: 3-4h;
(2), casting copper ingot: add deoxidier phosphorus and rice bran before the casting of copper liquid; Copper liquid coverture is added in crystallizer; Cast temperature is: 1150-1200 0C; Casting rate is: 4-11 m/h; Cooling water inflow is: 20 1 55 m3/h;
(3), heating forges: the processing of (1), forging blank; (2), forging blanking; (3), Forging Technology: heating-up temperature is: 820-8500C; Forging: pier is thick, punching, reaming is to the forging ' s block dimension of end ring; Forging terminates that forging is put into water and cools; Chilling temperature is: 50^-700C; Cool time is: 0.5-1 .5h; Then grinding forming, obtains the higher spot copper of purity.
The spot copper purity that the present invention makes is high, and appearance is good.
Detailed description of the invention
Below in conjunction with instantiation, the present invention is described in further details.
The section bar processing technology of mettled copper of Yunnan Province, comprises the following steps:
(1), melting: raw material selection T1 cathode copper through being smelted into copper liquid, covering copper liquid coverture in copper liquid; Fusing temperature is: 1050-1100 0C; Fusing time is: 3-4h;
(2), casting copper ingot: add deoxidier phosphorus and rice bran before the casting of copper liquid; Copper liquid coverture is added in crystallizer; Cast temperature is: 1150-1200 0C; Casting rate is: 4-11 m/h; Cooling water inflow is: 20 1 55 m3/h;
(3), heating forges: the processing of (1), forging blank; (2), forging blanking; (3), Forging Technology: heating-up temperature is: 820-8500C; Forging: pier is thick, punching, reaming is to the forging ' s block dimension of end ring; Forging terminates that forging is put into water and cools; Chilling temperature is: 50^-700C; Cool time is: 0.5-1 .5h; Then grinding forming, obtains the higher spot copper of purity.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
