- Q: What is the content of free silica in the refractory bricks of high alumina bricks?
- Refractory powders are not rich in free silica in varying degrees
- Q: What are the high temperature refractory mortars made of?
- Siliceous mud, mineral composition and chemical composition is similar with silica, excellent corrosion resistance, water glass slurry, drying shrinkage, but also can be used for bonding fiber products, sealing furnace wall.
- Q: The difference between ordinary and diatomite brick refractory brick
- To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
- Q: How are the grades of high alumina bricks differentiated?
- In China, the content of Al2O3 in high alumina brick is usually divided into three categories: I, etc. - Al2O3 content > 75%; II, etc. - Al2O3 content is 60 to 75%; III and so on - Al2O3 content is 48 ~ 60%.
- Q: What is the high temperature limit of refractory bricks and refractory soil?
- Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
- Q: What is the difference between fireclay bricks and high alumina refractory bricks?
- A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.
- Q: What should be used as binder for making high alumina bricks?
- In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
