The line frequency induction furnace will melt the cathode copper to liquid which will be protected by the charcoal covering on its surface from air to avoid oxidation of copper solution. The copper solution will be controlled to be 1150℃±10℃ through holding furnace, and it will crystallize rapidly in crystallizer and then produce copper rod by upward method continuously. At last the finish product will be made through double-line coiler and other auxiliary equipment.

2.5 机组的设备组成和结构说明Equipment composition and structure specification

机组由工频感应炉、连铸机、导轮架、限位装置、双头挠杆机、水冷却系统、电控系统、加料装置以及测温系统等组成。

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工频感应炉Line frequency induction furnace

工频感应炉主要由炉体、炉架和感应器三大部分组成。炉体外壳是钢结构，内部由耐火砖和石英砂砌筑而成。炉架起支撑整个炉子的作用，通过地脚螺栓固定在基础上。感应器由线圈、水套、铁芯以及熔沟组成，感应器的高压侧（初级）由带水冷的线圈组成，电压可从90V～420V有级可调，感应器的低压侧（次级）由短路的熔沟组成，通电后，在电磁感应的作用下，在熔沟内部产生大电流，低电压而使其熔化并将加入的电解铜熔化。水套和线圈均为水冷却，冷却水循环使用，由冷却水系统提供。

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连铸机Continuous casting machine

连铸机是实现上引连铸的主要设备。它由牵引机构、液位跟踪和结晶器三大部分组成。牵引机构由交流伺服电机和二组牵引辊轮等组成，它可实现每分钟0～400次的间歇运动并通过牵引辊轮将铸杆连续上引出来，每组牵引机构可带动2付牵引辊轮，分别牵引6根铸杆，并通过结晶器生产φ8mm 的铜杆。液位跟踪系统可保证连铸机上结晶器插入铜液的深度相对稳定，确保连铸生产的连续性。结晶器可将液态的铜快速冷却成固态铜并实现热交换，每根结晶器都能单独更换和控制,而不影响其它结晶器的正常工作。

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导轮架Guide wheel stand

 导轮架布置是在连铸机的上方，主要由平台、支架、竖导轮和滚筒组成，它使铸杆平滑地导入各组双头挠杆机，互不干扰。

The guide wheel stand lies above the continuous casting machine, which mainly consists of platform, bracket, vertical guide wheel and roller. It can guide the casting rod to each double-line coiler smoothly with no-interference.

2.5.4限位装置Limiting device

限位装置设置在导轮架和双头挠杆机之间，它装有低压上、下限位，通过铜杆与上下限位的接触来控制双头挠杆机的速度。

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双头挠杆机Double-line coiler

双头挠杆机是由牵引辊轮，成圈装置和收线转盘组成，每组双头挠杆机由二台电动机分别驱动两套装置收圈两根铜杆，曲率自动调整。

The double-line coiler consists of traction rolling wheel, coiling device and take-up rotary bobbin. Each double-line coiler is driven by two motors separately. Meanwhile, it will take up two rods in two coils, with adjustable curvature.
