Upward Continuous Casting System for Oxygen-Free Copper Rod D

Upward Continuous Casting Machine for Oxygen Free Copper Rod
 
This upward continuous casting system is used to produce bright and long oxygen-free copper rod. The system is capable of producing directly from cathode copper to bright and long oxygen-free copper rod , copper tube, flat copper bar and other special shaped copper material .The capacity of the system is in 4 models of 2000-3000 tons, 4000-6000 tons,8000-12000 tons and 15000 tons annually. And the copper rod diameters will be Ø8mm, Ø12.5 mm, Ø14.4 mm, Ø17 mm, Ø20 mm, Ø25 mm and so on.
As compared with the black copper rod produced by traditional mangler from copper ingot, the rod produced by this new upward continuous casting technology has its advantage of better quality, low production cost, low investment and no pollution in production.
Specifications of the modelfs the upward casting line:1.     the induction furnace
The induction furnace is consist of furnace body, furnace frame and inductor.   The outside of the furnace body is steel structure and the inside is consist of fire-clay brick and   quartz sand. The function of the furnace frame is support-ing the whole furnace. The furnace is   fixed on the base by the foot screw. The inductor is made up of coil, water jacket, iron core and   copper-ring. There are coils with water-jacket at the high voltage side. The voltage is adjustable   step by step from 90V to 420V.There are short-circuit copper rings at the low-voltage side. After set   up an electric circuit, it can emerge big current flow in the copper ring with the electromagnetic   induction. The big current flow can melt the copper ring and electrolytic copper putted into the   furnace. The water jacket and coil is cooled by the water. The cooling water is cycling and supplied   by the cooling water system.
2.     Continuous casting machine
The continuous casting machine is the main part of the system. It is consist of drawing   mechanism, following mechanism of liquid level and freezer.   The drawing mechanism is made up of A.C. servo motor, two groups of drawing rollers and so   on..It can produce 0-1000 times interval rotation per minute and draw up the copper rod continuous   by the drawing rollers. One of the drawing mechanisms can drive 5 drawing rollers and draw up 5   copper rods.The following mechanism of liquid level guarantee that the deep of the freezer   inserting into the copper liquid is relative stable.The freezer can cool the copper liquid into copper   rod by heat exchange. Every freezer can be changed and controlled alone.
3.     Frame of guide pulley
The frame of guide pulley is installed above the continuous casting machine. It is consist of   platform, support, vertical guide pulley and cylinder. It can lead the copper rod to the every   double-head wind machine without disturbance.
4.     Limited device 
The caging device are two devices installed between the frame of guide pulley and   double-head wind machine.   And down spacing which can control the speed of double-head wind machine by the   electrical signal produced by the copper rod touching the up or down spacing.
5.     Double-head wind machine
The double-head wind machine is made up of the drawing rollers, revolving chassis and   spooling take-up unit. Every double-head wind machine can take-up two copper rods.
6.     Cooling-water system  
The cooling water system is a cycling system. It can supply 0.2-0.4Mpa cooling water for   freezer, water jacket, coil. It is consist of 150M3 water pool, water pump, tube and cooling water   tower. The temperature of water supplied to the system is 20ºC-30 and the quantity of water ºC  flow is 50 M3/H7,Electrical system .The electrical system is consist of electrical power and control   system.   The electrical power system supply the energy to every inductor through the power cabinets.   The control system control the combined furnace, main machine, double-head wind machine and   cooling water system pledging them to work in order. The control system of combined furnace is   consist of melting furnace system and holding furnace system. The melting furnace operation   cabinet and holding furnace operation cabinet are installed near the system.
7.     Electrical control system
The main machine electrical control system is consist of drawing motor, elevator motor and   their electrical control system. The drawing motor is disposed control system alone. Every   double-head wind machine is controlled alone. A taking-up controlling board is fixed in the frame of   double-head wind machine. Its control knob is fixed on the surface of the frame. The cooling   water electrical system is an control box hung on the wall of water pump room. It can control two   water pumps.
8.     Charging system
The system can charging whole piece of copper plate into the furnace.
9.     Thermosister 
The thermosister is consist of temperature of copper liquid and temperature of cooling water.
