Do you know how to choose the correct acid furnace lining

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 production The acid furnace lining material of the kiln can obtain a dense 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 environments. It can also be used for Melting of titanium alloys and high temperature non-ferrous metals.

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

A. First, ensure that the acid lining material has the necessary structural strength at high temperature without softening and deformation.

B. The volume must be stable at high temperature, so as not to expand and contract to cause cracks.

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

D. Resistant to chemical attack by metal solution, slag and furnace gas

E. No sticky slag (or less sticky slag), easy to clean 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 is generated, and the molten liquid has a strong erosion on the furnace lining. Therefore, the material of the acid lining material is required to be dense, high strength, In order to be resistant to erosion, safe and long-term operation.
