Copper Tube / Rod Horizontal Continuous Casting Machine :
A typical horizontal continuous casting unit for copper tubes consists of a mains frequency cored melting-holding combined furnace with metal flowing under surface, a crystallizer, a cooling water distribution system, a servo control withdrawal system, an in-line synchronous saw, a saw for mold changing, a hydraulic system and an electric control system, etc.
A typical mains frequency furnace adopts a new combination structure of melting-casting with metal flowing under surface. The inductor adopts a vertical structure with silicon sheets imported. As the molten metal flows from the melting furnace to the holding furnace under the surface, the heat emission (that would be otherwise caused) is avoided so as to reduce the energy consumption. Meantime, the metal loss is also reduced. As the exposure of the molten metal to the air is substantially reduced, the product quality can be stabilized and enhanced. The parameters of the melting-holding furnace like voltage, amperage, effective power and compensation factor are indicated with signals. The metal temperature in the furnace is continuously measured and displayed. Also indicated are the temperatures and pressures for the water for cooling the inductor coils, wrapping sleeves and cables with necessary optic and acoustic alarms equipped.
Brass/Copper Horizontal Continuous Casting Process Presentation:
Melting furnace/ holding furnace:
Melting furnace is vertical structure and welded by steel plate, and the furnace consists of furnace body, inductor, tilting furnace system, electrical control. and about the Holding furnace, which is used for thermal insulation and traction. The holding furnace can be used separately, also can be used with melting furnace together.
Melting furnace: choose working frequency cored induction furnace. It consists of furnace frame, furnace body, inductor, water cooling system and electric control system.
Holding furnace: choose working frequency cored induction heat preservation furnace, which is composed of furnace induction body, furnace support, crystallizer, hydraulic system and hydraulic station, and electric control system.
The unit has the advantages of high yield, low labor , few workers and no pollution.
- Horizontal continuous caster
It is composed by the engine base, servo motor, reducer, traction wheel system. The servo motor is driven by the ac servo motor of yaskawa, Japan, and the reducer is driven by four shafts of worm wheel and worm, which can adjust the traction center up and down. After heat treatment, the surface hardness of traction wheel will be HRC40 – HRC45.The upper press wheel of the tractor is supported by two supports. When the billet enters the tractor, the upper press wheel is driven by the drive system.
Titighen the copper both the vertical and horizontal direction; High cutting efficiency and precision; Automative collection of the cutting slag; Low-voltage on the control cabinet for safe operation.
- Electrical control system
Working frequency of melting furnace and insulation needs to be graded voltage regulation, the lowest voltage is 90V, each increase of 30V as a first gear, the highest voltage is 380V.A total of 8 gears, insulation furnace can achieve automatic temperature control function.The e automatic servo system: PLC control, touch screen can achieve frequent pull, stop, push back, stop parameters of arbitrary Settings and modification. To achieve continuous pull, stop, push back, stop, can stop quickly, no crawling phenomenon. There is sufficient braking torque. The system has the function of changing process parameters online. The system has short circuit, overheat, overload, overvoltage, overcurrent and other protection functions. One PLC, one touch screen, one servo controller, one ac servo motor.
The water jacket of the horizontal continuous casting tube blank crystallizer is made of stainless steel tubes by combining primary water jacket with secondary water jacket. The copper inner sleeve is T2 copper casting, divided into primary copper inner sleeve and secondary copper inner sleeve. The graphite sleeve is made of high purity graphite and is made of graphite with high thermal conductivity and high temperature wear resistance. The graphite mould is an ideal material for continuous casting copper tube billets.(the whole set of crystallizer is manufactured and processed according to the design of our factory)
Hydraulic motivation for sending; Widely use for pipe, bar, flat, and irregular metal.
