What are the advantages of a good furnace lining

Currently,Furnace lining, is a coreless intermediate frequency induction furnace that is widely used in steel plants, foundries and metal manufacturing. Generally, intermediate frequency furnaces use amorphous refractory materials, and sometimes some shaped refractory materials are used.

So, what kind of furnace lining is better? What are the advantages of a truly qualified intermediate frequency furnace lining or what needs to be guaranteed? Today, the editor of Quantong Kiln Industry will give you a detailed understanding Lower furnace lining.

1. Selected raw materials

The quality of furnace lining raw materials requires high requirements, select raw materials to ensure high purity of raw materials, and ensure qualified and stable product quality.

2, the effect is stable

The material is based on the mixing of high-density quartz sand, adding part of fused silica, pre-phase-change treated quartz, high-temperature resistant binder, anti-quenching and rapid-heating stabilizer, anti-seepage agent, anti-cracking agent and other composite micropowder materials. It has the characteristics of strong resistance to molten iron corrosion, no cracking and slow loss, which successfully overcomes many disadvantages of traditional furnace lining materials.

3, temperature resistant

The temperature resistance needs to be suitable for the melting degree of 1400 degrees Celsius - 1780 degrees Celsius.

4, the construction is convenient

The material is a pre-mixed dry ramming mixture, and the content of sintering agent and mineralizer has been prepared according to the needs of use. No need to configure any materials, it can be directly used by dry vibration or ramming.

5, economical and durable

The high output 70-ton intermediate frequency steelmaking furnace has a furnace age of 35 to 60 furnaces, a 40-ton intermediate frequency steel-making furnace has a furnace age of 40 to 70 furnaces, and a 1-ton intermediate frequency casting furnace has a furnace life of 300 to 600 furnaces (reference value).

6, furnace age

Under the operating conditions, continuous use, smelting gray iron, pig iron, ductile iron and other cast iron raw materials, the normal lining usage times can reach more than 500 heats; and the normal lining life of smelting ordinary carbon steel, high carbon steel, high chromium steel can reach About 195 heats, the lining life of traditional products can be improved by more than 50%.
