A series of acid lining materials

I. General introduction

This product is a coreless induction furnace refractory material, the material is acidic. Using pre-phase change treated silicon ore as raw material, the expansion defect of furnace lining is obviously improved, the rising range of furnace lining is obviously reduced during drying, and there is no crack in cold furnace. It is characterized by high purity of raw materials, reasonable grading, resistance to acute cooling and acute heat, especially suitable for the intermittent operation of large medium frequency induction furnace. This material is premixed dry ramming mixture, according to customer demand has been prepared boric acid or boron anhydride content, users can directly put into use. It is suitable for melting temperature of 1400℃ -- 1700℃.

2. Technical data (chemical composition does not contain sintering agent)

SiO2 ≥ 99% CaO+MgO ≤0.1% _Fe2O3≤ 0.2%

Material density: 2.1g/cm3 Particle size: not more than 8.1mm

High use temperature :1700℃ Construction method: dry vibration or dry ramming

Third, furnace building, oven and sintering process

The correct furnace building, drying and sintering process is the key to the normal work of the lining. Before building and drying, please refer to the "furnace building and drying sintering process Description" of Anaijie Lining Materials Company.

4. Packaging standards and storage methods

Multi-layer moisture-proof paper and inner membrane packing 25kg/ bag, stored in a dry place to prevent moisture absorption. The storage period is not more than one year, in addition, according to customer requirements, 106cmX106cm tons of pallet and strong telescopic film packaging can be used.
