How to choose the lining material for acid induction furnace?What is the lining material of acid induction furnace?

The lining material of the acid induction furnace produced by the lining material of the loose guide induction furnace is made of high-purity microcrystalline quartz sand, powder and fused quartz, and the dry vibrating material is mixed with high-temperature sintering agent and mineralizer. The particle size and the addition of sintering agent are strictly controlled. Therefore, the acid induction furnace lining material produced by the loose guide induction furnace lining material can obtain a dense induction furnace lining regardless of various knotting methods. The induction furnace lining material is mainly used in the melting process of gray iron, ductile iron and carbon steel in foundries, and is suitable for continuous high-temperature environments, and can also be used for the melting of titanium alloys and high-temperature non-ferrous metals.

The choice of lining material for acid induction furnace should meet the following six characteristics:

1. First, ensure that the lining material of the acid induction furnace has the necessary structural strength at high temperatures without softening and deformation.

2. It must be stable in volume at high temperatures, so that it will not expand and shrink to cause cracks.

3. Når temperaturen ændrer sig kraftigt, eller opvarmningen er ujævn, vil den ikke revne og skalle af

4. Det kan modstå det kemiske angreb af metalopløsning, slagger og ovngas

5. Non-sticky slag (or less sticky slag), easy to clean, and keep the lining of the induction furnace intact.

The lining material of the acid induction furnace has high strength. The reason is that when the coreless furnace melts the metal, it produces a strong stirring force, and the melt has a strong erosion on the lining of the induction furnace. Therefore, the lining material of the acid induction furnace is required to be dense and high in strength to be resistant to erosion and safe. Long run.
