Description

Application choice of two kinds of zirconium ramming materials

Although both zirconium ramming materials have good resistance to vitrification and have very low pollution to glass, they still need to be reasonably selected according to the nature of the glass produced.

The ramming material consists of a gas phase, a crystal phase and a glass phase. Although the presence of the glass phase is advantageous for sintering, it is less resistant to corrosion by the glass liquid than the crystal phase, and is a weak link for the erosion resistance of the ramming material and other refractory materials. The nature and content have an important influence on the performance of the ramming material.

The pores are the channels through which the glass liquid penetrates into the ramming material. The porosity is high and the ramming material is resistant to chemical corrosion. This is because the pores are mostly concentrated in the bonding phase. Once the glass liquid penetrates into the ramming material, the gas phase, the glass phase and The etchant meets in multiple phases, forming the weakest point of resistance to erosion. Therefore, if the chemical composition is constant, the lower the total porosity, the stronger the erosion resistance.

The type and composition of the etchant also plays a large role in the erosion resistance of the ramming material. In glass furnaces, the etchant mainly refers to high temperature glass liquid and dense metal or metal oxide deposited on the bottom of the pool. Different glass solutions have different effects on the ramming material. The characteristic rate of erosion and the form of erosion are very different between soda-lime-silica glass, borosilicate glass, lead glass and other types of glass.

The main difference between fused AZS ramming and zircon ramming is the content of Al2O3 and porosity. Since there is a masonry gap in the paving brick located on the upper layer of the zirconium ramming material, the glass liquid will penetrate into the ramming layer through the brick joint, and the erosion resistance of the ramming material will be due to the chemical composition, movement speed and temperature of the glass liquid. Different. The soda-lime-silica glass melt is highly aggressive due to the ionized alkali in the melt, and the ionized alkali is the driving force of the corrosion mechanism when they are in contact with the ramming material. The viscosity of the melt also has a large effect on the rate of erosion, regardless of which glass system is in the range, and the erosion increases sharply with decreasing viscosity.

The following is a further explanation of the action occurring when zircon ramming and fused AZS granules are in contact with alkaline glass.

(1) The fused AZS mashing material is in contact with the alkaline glass liquid, and the aluminum (Al2O3) layer is formed at the contact interface. The ZrO2 in the ramming material is melted in the glass liquid to a low degree, the viscosity is increased, and the interface layer is blunt. Chemical properties, anti-mechanical wear and chemical resistance.

(2) The Zircon ramming mass is in contact with the alkaline glass liquid. Since there is no aluminum in the zircon ramming material, zircon is easily decomposed, and the decomposed SiO2 will lower the viscosity, thereby accelerating the erosion, resulting in The beating layer is damaged.
