Box Type Degassing Unit
Introduction
In the aluminum melting and processing industry, product quality and production efficiency are always the core concerns of enterprises. With the increasing demand for high-quality aluminum, the purity of liquid aluminum becomes particularly important. Gases and impurities in liquid aluminum can affect product performance, resulting in production defects and waste.
As one of the most effective molten aluminum degassing technologies, the box degassing device efficiently removes gases and inclusions from liquid aluminum, making it the preferred solution for high-end aluminum castings.
In a box type degassing device, the rotor rotates at high speed in the box to disperse the inert gas to form a large number of small dispersed bubbles. These small bubbles enter the aluminum liquid, and carry away the hydrogen and oxidation slag in the aluminum liquid with the floating, to achieve the purpose of degassing and refining. During the rise of the bubble, the inclusions will be brought out of the surface of the liquid aluminum by surface tension to form scum, so as to effectively remove impurities. At the same time, the stirring of the rotor makes the alloy composition in the aluminum liquid more uniform, and further improves the quality of the aluminum liquid. Through this process, the box degassing unit significantly improves the purity and performance of the aluminum.
Product feature
◆ Optimal gas dispersion: The dispersion of process gas in liquid aluminum is excellent, ensuring full contact between bubbles and liquid aluminum.
◆ Seal design: The box is completely sealed to provide a stable inert gas environment and eliminate external influences.
◆ Smooth liquid aluminum surface: The liquid aluminum surface remains smooth to avoid turbulence and improve casting quality.
◆ Easy maintenance: The installation and maintenance is easy. The lining of the pre-fired degassing box can be changed quickly to reduce downtime.
◆ Low operating costs: The overall maintenance and operation costs are low, and the rotor and shaft have a long life to ensure the long-term stability of the equipment.
◆ Durable: The heater and its protective tube have a long service life, and the cooling gas does not require the rotor rotating spindle, reducing energy consumption.

Reverberatory Furnace
Waste copper rectangular fixed-type reverberatory furnace is a special smelting equipment that uses liquefied petroleum gas, heavy oil or natural gas as fuel and scrap copper as raw material to complete melting, oxidation (slagging), reduction and other smelting processes.
The reverberatory furnace is mainly composed of steel structure, refractory material, furnace door and transmission equipment, gas burner, air supply system and electronic control system.
The reverberatory furnace provided by us has advantages of simple structure, good adaptability to raw materials and fuels, long furnace life, convenient operation, easy control, high operation rate, suitable for large, medium and small scale production, and less water consumption in production and so on.
According to customer requirements, the capacity of the reverberatory furnace can be designed such as 40t, 60t, 100t, etc.
Wheel Casting Machine
The liquid copper which are refined by the reverberatory furnace cast in the crystal wheel cavity of the casting machine through launder and pouring pot. After water cooling, the liquid copper will rapidly condensed and solidified into the casting rod ingot.
The wheel casting machine is mainly composed of driving mechanism(body), crystallization wheel, compaction wheel, tensioner, pouring pot device, cooling device, drying device, ingot puller, lead bridge, carbon coating device, flow control device, and air-drying device, etc.
The crystallization wheel provided by us uses copper-chromium-zirconium. This crystallization wheel has advantages of high hardness, wear resistance, antiknock, good cracking resistance, high production efficiency, long service life, and long-term continuous production.
Continuous Rolling Mill
Continuous rolling of copper rod ingots manufactured by the casting machine.
The rolling mill provided by us adopts active feeding, the final rolling speed can reach (8.1～9.9) m/s, and the outer diameter of rod is 8mm. It has advantages of convenient operation, easy control, high production efficiency, stable rod diameter, bright copper rod, etc.
Commercial Parts
1. PLC programmable use Germany Siemens, Touch screen use Germany Siemens.
2. DC control system uses Germany Siemens.
3. Button use Schneider, Control Relay uses Omron, others use domestic China.
4. All frequency converters use Siemens (China).
5. All AC motors use Siemens Bede (China).
Raw Materials
The copper continuous casting and rolling production line provided by us can use scrap copper as raw material for copper rod production.
Scrap copper of grade 1 or above grade 2 are used in a certain proportion.
Among them: Scrap copper of grade 1 should be clean and non-alloy copper wires free from tin, containing no fragile burned wires which including bare, uncoated, alloy-free copper wire with no oxidation on the surface and no wool. The diameter of the copper wire is not less than 1.6mm.
Scrap copper of grade 2 should be small diameter non-insulated copper wires, usually containing telephone wires, copper strip with varnish or paper insulation, and thick or thin clean copper bar, also including clean, colorless, uncoated, tin-free, alloy-free copper wires and cables, free of wool and burnt brittle copper wires.
Scrap Copper Baler
Scrap copper needs to be packed into copper blocks by scrap copper baler before casting. The scrap copper baler is shown below:
The scrap copper baler adopts hydraulically driven, and has characteristics of simple structure, durable, convenient operation, fast packing speed, compact packing block and so on. The scrap copper can be extruded into various shapes such as cubes, cylinders, etc., which can not only reduce transportation and smelting costs, but also improve the speed of furnace operation. The packed copper block is shown below:
Installation And Commissioning
1. 14 days before the inspection before delivery at Manufacturer’s plant, the Buyer shall inform the plan schedule of installation, commissioning and test production to the Seller. The both parties will finalize this plan during the period of inspection visit.
2. All the civil work should be done by the customer according to the drawings from manufacturer. The buyer should prepare all raw materials, auxiliary materials, production tools, production workers and etc
