Drain and dross pan is the most effective equipment for the management and treatment of aluminum dross, which can recover aluminum efficiently and with high quality, increasing the amount of aluminum recovered by 90-95%. Because the drain and dross pan is in the high-temperature aluminum dross 750℃-1050℃ for a long time, and also works in a corrosive environment, the choice of materials is very important, ductile iron, cast steel, alloy steel, carbon steel and other 4 different materials of the dross pan, each has different advantages:
Ductile cast iron drain and dross pan
Advantage:
1. Good high temperature resistance, wear resistance and high strength
2. Low cost
3.Long service life
Disadvantage:
1. It is more corrosion resistant than gray cast iron, but it can also be corroded in environments containing alumina or corrosive substances
2. The slag sticking to the wall will lead to the uneven wall thickness of the drain and dross pan, and it is easy to crack after being knocked and then chilled or heated
When high strength, wear resistance and high temperature resistance are required for manufacturing, and the cost requirement is low, the drain and dross pan of ductile cast iron is a good choice.
Cast steel drain and dross pan
Advantage:
1.High strength and toughness, can withstand relatively large mechanical shock and thermal stress
2. High temperature resistance, wear resistance, corrosion resistance
3. Weldability, easy to repair
Disadvantage:
1.Higher than the cost of ductile cast iron, especially high-quality alloy steel
2. Compared with cast iron, the processing difficulty of cast steel is greater, and the processing time and cost are relatively high
It is suitable for the manufacture of high strength, high toughness and wear resistance, especially in the environment of high temperature and impact resistance, its advantages are more obvious, and the cast steel drain and dross pan can be selected without strict control of the cost.
Carbon steel drain and dross pan
Advantage:
1. It has good strength and toughness, and can withstand large mechanical impact and thermal stress
2. High temperature resistance, wear resistance
3. Weldability, easy to repair
Disadvantage:
1. Low carbon steel is easily corroded in a high temperature or humid environment, and the surface needs to be treated, such as galvanized or painted to improve corrosion resistance
2. High carbon steel may be brittle at low temperatures, and it is necessary to pay attention to the ambient temperature of manufacturing
Carbon steel drain and dross pan has a lower cost than cast steel and can be selected on a limited budget but where high performance is required
In conclusion, the material selection of drain and dross pan depends on various factors, and the materials with the best performance can be selected according to their actual conditions, in order to reduce the cost of frequent replacement or maintenance, improve the amount and quality of aluminum recovery, and increase more economic benefits.
