This material is based on microcrystalline quartz, and is mixed with a series of imported composite refractory micropowders such as fused quartz, high temperature resistant binder, anti-surge heat stabilizer, anti-seepage agent, and anti-cracking agent. According to the furnace temperature, it is mixed with a proper amount of mineralizer in the material and mixed according to the ideal ratio of the proprietary particle size design. It has strong acid slag resistance and can be used to smelt a series of metals such as pig iron, ductile iron gray iron, carbon steel, alloy steel, copper and aluminum. .

The material basically expands at 1200-1400°C. The volume change above this temperature is very small. The thermal stability and resistance to molten iron leakage are very good. Its load softening temperature is high, impact resistance is strong, and molten iron corrosion resistance. When the temperature is 1780℃C, the volume not only does not shrink, but also expands slightly. It has good high temperature stability, and it can be made without cracking and without wearing the furnace. For a well-sintered quartz sand furnace lining, due to the slow transformation of quartz, the expansion and contraction of the furnace lining are relatively stable, and the loss is extremely slow, thereby greatly improving the service life of the furnace lining.

The material expands slightly when working, and changes little when it shrinks when cooled, that is, it has a very good resistance to chilling and heat. It has many advantages such as enhanced hot metal corrosion resistance, extreme cold and extreme heat resistance, high softness, strong impact resistance, high load softening temperature, compressive and high temperature strength, high temperature flexural strength, slag resistance, etc.

Especially suitable for intermittent operation of large-scale intermediate frequency electric furnace.

【Selected raw materials】

The selected purity of 98.5% microcrystalline quartz is used as the base material to ensure the high purity, high quality and stable performance of the material.

[Stable effect]

It has the characteristics of strong resistance to molten iron corrosion, no cracking, slow loss, etc., successfully breaking through many shortcomings of traditional furnace lining materials.

【High energy and temperature resistance】

It is suitable for smelting temperature of 1400℃-1780℃, and can be suitable for most modern medium frequency electric furnace smelting and casting temperature resistance requirements.

[Convenient construction]

The material has been pre-mixed with dry ramming mixture, and the content of sintering agent and mineralizer has been prepared. The user does not need to configure any materials, and can be directly used by dry vibrating or ramming.

【Excellent furnace age】

The life of the furnace lining in normal use is as high as 600 times or more, which is significantly longer than that of traditional products.

【Production increase】

The age of the 70-ton intermediate frequency steelmaking furnace is 35 to 60 furnaces

The 40-ton intermediate frequency steelmaking furnace has a fire age of 40-70 furnaces

The 1 ton intermediate frequency casting furnace has a furnace age of 400 to 600 furnaces
