Correct selection tips for acid furnace lining materials

What is Acid Furnace Lining?

The acid lining material produced by Sinosteel Jinjian 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 are strictly controlled. The acid lining material produced by Gangjinjian lining material 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. It can also be used in the melting of titanium alloys and high temperature non-ferrous metals.

The selection of acid lining materials should meet the following 6 characteristics:

1. First, ensure that the acid lining material has the necessary structural strength at high temperature and does not soften and deform.

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

3. When the temperature changes sharply or the heating is uneven, it will not break and fall off

4. It can resist the chemical attack of metal solution, slag and furnace gas, etc.

5. No sticky slag (or less sticky slag), easy to arrange and keep the furnace lining intact.

6. 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 scouring on the furnace lining. Therefore, the material of the acid lining material is required to be fine, high strength, Ability to scour, safe and long-lasting operation.
