Zirconium Ramming Material
The zirconium ramming material is made up of a high proportion of granular materials, a very low proportion of binders and other components, and even all of them are composed of granules and powder materials. They must be constructed by strong ramming. State material. Because the ramming material is mainly used in the direct contact part with the molten material, the granular and powder materials are required to have high volume stability, compactness and corrosion resistance, and they should also have insulation properties for induction furnaces. To Zirconium ramming materials mainly refer to

Zirconium Ramming Material Details
The zirconium ramming material is made up of a high proportion of granular materials, a very low proportion of binders and other components, and even all of them are composed of granules and powder materials. They must be constructed by strong ramming. State material. Because the ramming material is mainly used in the direct contact part with the molten material, the granular and powder materials are required to have high volume stability, compactness and corrosion resistance, and they should also have insulation properties for induction furnaces. To
Zirconium ramming materials mainly refer to zirconium-containing ramming materials. Zircon ramming material is made of phosphoric acid or acid aluminum phosphate as binder, zircon (or zircon and corundum) is used as refractory aggregate and powder, and an appropriate amount of sintering aid is added to configure unshaped refractory material.
The corrosion resistance of refractory materials to high-temperature molten glass is an important factor that determines the life of the glass furnace and the quality of glass products. Zirconium ramming material can be widely used in the bottom of glass kiln. In addition to the characteristics of good integrity, good sealing, and strong adaptability, it also benefits from the superior corrosion resistance and super high refractoriness of zirconium materials. , Zirconium aggregate is the skeleton of zirconium ramming material, which plays an important role in the high-temperature physical properties of zirconium ramming material. Currently, there are two main types of zirconium ramming material used at the bottom of the glass furnace: one is electric Melting AZS ramming material, one is zircon ramming material.
Features
High temperature resistance and high compressive strength;
Low thermal expansion and shrinkage; strong resistance to glass solution corrosion;
Excellent thermal shock resistance;
Can be mashed into any shape.
Application
It is mainly used as a bottom lining under the zirconia corundum mullite bricks in the glass kiln. It can also be used as the filler for the expansion joints of silica brick masonry and the transition layer material between siliceous and high-alumina refractory products, and some The inner lining of the induction furnace and the melt launder.
