Information

Castable for aluminum manufacturers tell you that with the continuous development of the metal smelting industry, aluminum products have been applied to various industries, and the thermal kilns for aluminum smelting applications are collectively referred to as aluminum melting furnaces. The manufacturer of Castable for aluminum tells you that the melting point of aluminum is 660℃, which is relatively low among many metals. However, aluminum is very active and has very strong penetration ability. It is very easy to corrode the refractory castable lining and change its performance. Cause cracks and peeling. Therefore, it is very important to choose the material of refractory castable.

Reasons for damage of aluminum melting furnace lining
There are three main reasons for the damage of the aluminum melting furnace lining:
1. The manufacturer of Castable for aluminum tells you that the temperature of the aluminum melt in the furnace is not high, but it is very penetrating. The aluminum melt with very high activity slowly penetrates into the furnace lining through the pores and fine lines of the furnace lining, and physically interacts with the furnace lining. , The chemical reaction gradually loosens and peels off the furnace lining, causing the furnace lining cracks to increase and fall off.
2. The aluminum melt in the furnace chemically reacts with the furnace lining to form adhesion, and the adhesion will increase over time to form nodules, which will damage the furnace lining.
3. The Castable for aluminum manufacturer tells you that during the process of adding raw materials or slagging, bauxite or aluminum slag will cause a certain degree of impact and wear on the furnace lining, which will cause physical loss of the furnace lining.
Features of non-stick aluminum refractory castable
The Castable for aluminum manufacturer tells you that the non-stick aluminum refractory castable is made of special high-grade alumina, brown corundum, kyanite, alumina powder, calcium aluminate cement, silica powder and special additives through a strict ratio of mixing. The Castable for aluminum manufacturer tells you that it is a low-cement refractory castable specially developed according to the requirements of the use of aluminum melting furnaces. It has the performance characteristics of low impurity content, high density, high strength, high corrosion resistance, high permeability resistance, and no infiltration by molten aluminum. Table 1 shows the performance indexes of non-stick aluminum refractory castables.
Castable for aluminum manufacturers tell you that non-stick aluminum refractory castables can be used for aluminum melting furnace bottoms, lower furnace walls, slag slopes, chutes, aluminum ladle and other severely corroded parts with their superior resistance to aluminum corrosion. After use, the corrosion and nodulation of molten aluminum can be controlled and delayed to a large extent.
The manufacturer of Castable for aluminum tells you that non-stick aluminum refractory castable, as a tailor-made lining material for aluminum melting furnaces, has been applied to the construction of aluminum melting furnaces in many large domestic aluminum factories and aluminum alloy processing enterprises. At present, users have consistently responded well, and its superior performance has effectively extended the life of the aluminum melting furnace to more than 10 months.
