Upward continuous casting system for the production of copper tube

copper tube1

The upward continuous casting system(known as Upcast technology) is mainly used to produce high quality oxygen free copper rod for wire and cable industries. With some special design, it is capable to make some copper alloys for various applications or some profiles like tubes and bus bar.

Our upward continuous casting system can produce bright and long copper tube for applying in the household and industrial industries.

The upward continuous casting system melts the whole piece of cathode into liquid by the induction furnace. The copper solution covered with charcoal is controlled temperature to 1150℃±10℃ and crystallized fast by the freezer. Then we can get the oxygen free copper tube which pass the frame of guide pulley, glider wheel conveyer and take up by the straight line and cut manually system.

The system is a continuous and high-effective production line with characters of high quality product, low investment, easy operation, low running cost, flexible in changing production size and no pollution to environment.

Composition of our Upward continuous casting machine for the production of copper tube

1. Induction furnace

The induction furnace consists of furnace body, furnace frame and inductor. The outside of the furnace body is steel structure and the inside consist of fire-clay brick and quartz sand. The function of the furnace frame is supporting 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 are cooled by the water. Continuous casting machine

The continuous casting machine is the main part of the system. It is consisting of drawing mechanism, following mechanism of liquid level and freezer. The drawing mechanism is made up of A.C. servo motor, groups of drawing rollers and so on. It can produce 0-1000 times interval rotation per minute and draw up the copper tube continuous by the drawing rollers. The following mechanism of liquid level guarantees that the deep of the freezer inserting into the copper liquid is relative stable. The freezer can cool the copper liquid into copper tube by heat exchange. Every freezer can be changed and controlled alone.

4. Electrical system

The electrical system is consisting of electrical power and control system. The electrical power system supplies the energy to every inductor through the power cabinets. The control system control the combined furnace, main–machine, take-up and cooling water system pledging them to work in order. The control system of combined furnace consists of melting furnace system and holding furnace system. The melting furnace operation cabinet and holding furnace operation cabinet are installed near the system.
