Refractory Zirmul Bricks for glass furnaces
Model Number:
Certification:
Minimum Order Quantity:
Zircon diamond stone bricks is made by the zircon ore as raw material, adding a small amount of plastic clay, mixing, compacting and calcined into clumps. The lump is then crushed and added a small amount of plastic clay or other organic binders and mixed, shaped, and burned. Calcination and firing temperature should not exceed 1600 degrees, generally can be done by 1400 hours under a long time insulation to burn.
Zircon diamond stone brickss, a kind of shaped refractory brick, are manufactured with stable zircon sand and over 64% zircon content. Zircon diamond stone bricks belongs to acid refractory material with various properties of high mechanical strength, good thermal shock resistance, high refractoriness under load, strong erosion resistance and high density and etc. Zircon diamond stone brickss can be widely used in glass furnace, Ladle, pure steel furnace, non-ferrous metal smelting furnace and so on.
Advantage:
1.Competitive Price. Make the products competitive in your market.
2.Abundant Experience. Prevent cracks and twist in bricks.
3.Different Moulds. Save mould fees for you.
4.Lower ferric Oxide,porosity,higher refractoriness,density,higher CCS and exact tolerance.
5.Strict Quality Control. Meet clients' quality requirement.
6.Safty packing,prompt delivery time,and excellent after-sales services.
7.Large stocks. Guarantee prompt delivery.
8.Professional Packing. Avoid damage and secure the goods in transportation
Typical Features:
1. Low porosity, high compressive strength, flexural strength of high pressure, good bulk stability;
2. Good thermal shock resistance, anti-spalling
3. Easy-to-skin hanging in the kiln, and low thermal conductivity;
4. High temperature of refractoriness under load.
5. Ultra-high-temperature firing, high direct binding rate, high refractoriness and corrosion resistance.
6. Strong resistance against alkaline substances, the acid resistance better than the magnesia refractories.
