Introduction

With the continuous development of the application of aluminum materials, the requirements for its inherent quality are becoming higher and higher. The key to ensure the quality of aluminum materials is clean aluminum molten liquid.

Among the factors affecting the purity of aluminum liquid, the precipitation of hydrogen in aluminum liquid during solidification will lead to porosity and other defects, which not only destroys the internal continuity of aluminum, reduces the effective cross-sectional area, but also is the source of cracks.

Therefore, degassing plays an important role in the production of high-quality aluminum.
The launder type online rotating degassing unit is installed between the furnace and the casting machine along the length direction of the launder, and the degassing area is divided into several stages by a baffle to realize multi-stage online degassing and improve the degassing efficiency. The submersible baffle and insulation cover are used to form a closed space to prevent air from entering the degassing chamber, effectively reducing the suction and surface oxidation of aluminum liquid.

Product features

◆ The degassing efficiency is high, up to 40%. Multi-zone continuous degassing is adopted to increase the contact area and time between bubbles and aluminum liquid. The overall sealing of the box ensures that the top forms an inert space with the aluminum liquid surface during the casting process, prevents producing more oxidation slag due to liquid oxygenation of aluminum, prevents secondary pollution, and improves the degassing efficiency.

◆ The use of launder for degassing can reduce the residual aluminum liquid and metal loss, lower maintenance costs, and make the launder replacement convenient and fast.

◆ Easy to switch alloys quickly. Since there is no heating device and no deep box, most of the degassed aluminum liquid is made into products at the end of each casting. The remaining aluminum liquid in the degassing chute can be easily cleaned, which facilitates the rapid switching of alloys.

◆ It is especially suitable for semi-continuous casting production lines such as casting rod and recycled aluminum ingot. The alloy of this kind of casting process is changed frequently, and the requirement of hydrogen removal is not high.

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.

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:

10014dx0
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:
