How to choose acid furnace lining correctly

 The acid furnace lining material produced by gravity furnace lining material is made of high-purity microcrystalline quartz sand, powder and fused silica, dry vibrating material mixed with high temperature sintering agent and mineralizer, and the particle size and the amount of sintering agent added are strictly controlled, so the gravity furnace lining material The acid lining material produced can obtain fine lining regardless of various knotting methods. The 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 environment. For the melting of titanium alloys and high temperature non-ferrous metals.

The selection of acid furnace lining should meet the following characteristics:

A. Mainly ensure that the acid lining material has the necessary structural strength at high temperature and does not soften and deform.

B. It is necessary to stabilize the volume at high temperature, so as not to cause cracks due to expansion and contraction.

C. When the temperature changes sharply or is heated unevenly, it will not crack and fall off

D. Can resist the chemical attack of metal solution, slag and furnace gas

E. No sticky slag (or less sticky slag), easy to arrange and keep the integrity of the furnace lining.

F. The acid lining material has high strength. The reason is that when the metal is melted in the coreless furnace, a strong stirring force occurs, and the molten liquid has a strong erosion on the furnace lining. Therefore, the material of the acid lining material is required to be fine, high strength, The ability to scour, safe and long-term operation.
