Vertical oxygen free copper rod continuous casting machine

Breif introduction for copper rod up casting machine  

Copper rod continuous casting machine is specially used for making copper rod with different sizes.In the copper rod continuous casting machine production line, Copper cathode to be put on the furnace through the lifting system for baking→Ajust the feeding speed according to the casting speed. Feed the copper cathode into the melting furnace for melting (charcle to be used for avoiding the oxygen) → Flow into the transition part (charcle still need to be used for avoiding the oxygen) → Flow into the holding furnace → Flow into the crystallizer, and the copper rods come out → Flow into the casting device → Go through the output frame →Go through the separate shelf (to separate each rod)  → Go through the tension tower ( to contrl the take up speed) → Go through the take up machine, and finish coiling.

Furnace(Melting furnace and holding furnace)

This copper rod production line adopts power frequency induction furnace, which 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.

Continuous Casting Machine

The copper rod continuous casting machine is the main part of the production line. It consists 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.

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.

Limited Device

The caging device are two devices installed between the frame of guide pulley and double-head wind machine. It is fitted with 5 groups of 24V up 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.

Double-station Coiling Machine

The double-station coiling machine is made up of the drawing rollers, revolving chassis and spooling take-up unit. Every double-station coiling machine can take-up two copper rods.

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 20-30 and the quantity of water flow is 50 M3/H7,Electrical system .

 Cooling method: Water in and out from the two holes.

Electric Control System

The electric control system consists of electrical power and control system.
The electric 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. The system can charge whole piece of copper plate.
