Measures on how to extend the age of glass kiln

refractory materials: the quality of refractory materials in all parts of the kiln must be ensured, the refractory materials in different parts should be properly matched, the parts that need to do acid and alkali separation must be separated by reliable materials, the refractory materials in contact with the glass liquid must be able to resist glass liquid erosion and scouring, the lattice body materials in the heat storage chamber and the upper section should be resistant to high temperature and alkaline dust erosion.

Refractory materials for the heat storage chamber of glass kilns - silica bricks

The main function of the heat storage chamber as a waste heat recovery equipment of the kiln is to preheat the air to a sufficiently high temperature. The heat storage capacity of the heat storage chamber depends on the heat transfer area of the lattice body.

Analysis of new fireproof material technology development trend

In recent years, the research of flame retardant technology and the development and application of flame retardant products have received attention from all walks of life. The main development directions are: the development of multi-effect, high-efficiency, low water-soluble dehydration into carbon catalysts and foaming agents; a variety of flame retardants synergistic role of reasonable collocation; resin collocation modification, improve the fire performance and physical and chemical properties of fire-resistant materials; intumescent and non-intumescent fire paint combination; inorganic non-halogen intumescent fire paint, the key part of the development of fire protection materials technology is a large space water cannon.

The role of electrofusion bricks in glass furnaces

After the analysis of the relevant experts, on the glass furnace, in order to reach the design of the use of years or perhaps to reach the glass solution is not contaminated, we must have a comprehensive understanding of the appearance of the quality of the electrofusion brick and the internal quality.

The development status of sintered alumina materials in China

Tabular Alumina, also known as Tabular Alumina, is a type of sintered alumina that is rapidly sintered at a temperature of 1925°C, slightly below the melting point of α-Al2O3 (2050°C), and the grains reach a completely recrystallized α-Al2O3 with a two-dimensional planar platelet shape and a microstructure characterized by more inter- and intracrystalline rounded closed pores.

Refractory materials Bauxite for casting

Bauxite (aluminous soil; bauxite), also known as bauxite or bauxite, is an earthy mineral whose main component is alumina, which is hydrated aluminum oxide containing impurities. White or off-white, brownish yellow or light red due to iron content. Density 3.9~4g/cm3, hardness 1~3, opaque, brittle. Extremely difficult to melt. Insoluble in water, can dissolve in sulfuric acid, sodium hydroxide solution. Mainly used in aluminum refining, refractory materials.

Causes of porosity during the casting of electrofused zirconium corundum bricks

There are two types of pores in the casting, one is microscopic pores, which can only be seen under the microscope when made into thin sections; the other is macroscopic pores, visible to the naked eye, which is what we often call pores. They come from no more than four aspects: namely, the furnace material, melting process, casting material, casting process.
