2.5 機組的設備組成和結構說(shuō)明Equipment composition and structure specification
機組由工頻感應爐、連鑄機、導輪架、限位裝置、雙頭撓桿機、水冷卻系統、電控系統、加料裝置以及測溫系統等組成。
The machine is mainly composed of line frequency induction furnace, continuous casting machine, guide wheel stand, limiting device, double-line coiler, water cooling system, electric control system, charging device, temperature measurement system and so on.
2.5.1工頻感應爐Line frequency induction furnace
工頻感應爐主要由爐體、爐架和感應器三大部分組成。爐體外殼是鋼結構,內部由耐火磚和石英砂砌筑而成。爐架起支撐整個(gè)爐子的作用,通過(guò)地腳螺栓固定在基礎上。感應器由線(xiàn)圈、水套、鐵芯以及熔溝組成,感應器的高壓側(初級)由帶水冷的線(xiàn)圈組成,電壓可從90V~420V有級可調,感應器的低壓側(次級)由短路的熔溝組成,通電后,在電磁感應的作用下,在熔溝內部產(chǎn)生大電流,低電壓而使其熔化并將加入的電解銅熔化。水套和線(xiàn)圈均為水冷卻,冷卻水循環(huán)使用,由冷卻水系統提供。
The line frequency induction furnace mainly consists of furnace body, furnace frame and inductor. The shell of the furnace is steel structure, and the inner is constructed by refractory bricks and quartz sand. The furnace frame which is fixed on the foundation by anchor bolt is used to support the whole furnace. The inductor consists of wire coil, water jacket, iron core and melting channel. The high voltage side of the inductor (primary) is made up of coil of water cooling, whose voltage can be adjusted from 90V to 420V in step. The low voltage side (secondary) is made up of short circuited melting channel, after energizing, it will generate heavy current inside the melting channel under the action of electromagnetic induction, the low voltage will melt the cathode copper charged in. The water jacket and wire coil are both water cooling and the cooling water which is supplied by water cooling system can be used circularly.
2.5.2連鑄機Continuous casting machine
連鑄機是實(shí)現上引連鑄的主要設備。它由牽引機構、液位跟蹤和結晶器三大部分組成。牽引機構由交流伺服電機和二組牽引輥輪等組成,它可實(shí)現每分鐘0~400次的間歇運動(dòng)并通過(guò)牽引輥輪將鑄桿連續上引出來(lái),每組牽引機構可帶動(dòng)2付牽引輥輪,分別牽引6根鑄桿,并通過(guò)結晶器生產(chǎn)φ8mm 的銅桿。液位跟蹤系統可保證連鑄機上結晶器插入銅液的深度相對穩定,確保連鑄生產(chǎn)的連續性。結晶器可將液態(tài)的銅快速冷卻成固態(tài)銅并實(shí)現熱交換,每根結晶器都能單獨更換和控制,而不影響其它結晶器的正常工作。
The continuous casting machine is main equipment to realize upward continuous casting, which is composed of traction mechanism, liquid level track and crystallizer. The traction mechanism consists of A.C servo motor and two groups of traction rolling wheel, etc, which can realize 0 to 400 intermittent movements in one minute and can guide the casting rod through traction rolling wheel upward continuously. Each group of traction mechanism can drive 2 pairs of traction rolling wheels, which can pull 6 casting rods separately, and produce copper rod of φ8mm through crystallizer. Liquid level tracking system can guarantee that the inserted depth of the crystallizer on the continuous casting machine into the copper solution will be relatively stable to make sure that the casting production can go on continuously. Crystallizer can change the liquid copper to solid copper rapidly and meanwhile realize heat exchange. Each crystallizer can be controlled and changed individually, which will not influence the normal operation of other crystallizers.
2.5.3導輪架Guide wheel stand
導輪架布置是在連鑄機的上方,主要由平臺、支架、豎導輪和滾筒組成,它使鑄桿平滑地導入各組雙頭撓桿機,互不干擾。

限位裝置設置在導輪架和雙頭撓桿機之間,它裝有低壓上、下限位,通過(guò)銅桿與上下限位的接觸來(lái)控制雙頭撓桿機的速度。
The limiting device lies between the guide wheel stand and double-line coiler, which equips low voltage upper and lower position limiter. It can control the speed of the double-line coiler through contact between copper rod and upper and lower position limiter.
2.5.5雙頭撓桿機Double-line coiler
雙頭撓桿機是由牽引輥輪,成圈裝置和收線(xiàn)轉盤(pán)組成,每組雙頭撓桿機由二臺電動(dòng)機分別驅動(dòng)兩套裝置收圈兩根銅桿,曲率自動(dòng)調整。
