Quartz dry lining material is an acidic lining material for coreless induction furnaces based on silicon oxide, widely used in the melting process of gray iron, ductile iron, and forging iron. It is suitable for both periodic cooling melting and continuous insulation environment. In addition, this material is also suitable for various ferroalloys, cast steel and cast iron mixing, copper casting, etc.
Detailed Introduction
Basic features:; Quartz based dry furnace lining material is a coreless material based on silicon oxide; Acidic lining material for furnaces, widely used in gray iron, ductile iron, and forging; During the process of melting with iron, it is suitable for both periodic cooling and melting; Continuous insulation environment. In addition, this material is also suitable for various ferroalloys, cast steel and cast iron mixing, copper casting, etc.
Add silicon oxide based acidic materials according to the requirements of the usage environment; Electric fused quartz, utilizing the theory of tight packing and strictly controlling the particle size distribution, improves the expected service life of the furnace lining.
Characteristics: Easy to knot, excellent thermal shock resistance, low permeability, excellent volume stability.
Packaging: 25kg packaging, plastic inner film; Store in a dry place to avoid moisture; It is recommended to store for no more than 12 months.
Baking: Proper furnace construction and sintering processes are key to ensuring the service life of furnace lining. Suggested baking temperature is 1580 ℃~1620 ℃; The heating rate shall not exceed 110 ℃/h, the initial insulation temperature shall be 1100 ℃ for more than 2 hours, and the final insulation temperature shall be greater than 1 hour.
Attention: The International Agency for Research on Cancer has listed silica and some silicates as carcinogens. During storage, handling, and construction, please ensure dust prevention measures are taken to avoid inhalation.
