Refractory Zirmul Bricks for glass furnaces
Zirmul 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.
Zirmul Brickss, a kind of shaped refractory brick, are manufactured
with stable zircon sand and over 64% zircon content. Zirmul 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. Zirmul Brickss can be widely used in glass
furnace, Ladle, pure steel furnace, non-ferrous metal smelting
furnace and so on.
Zirmul Bricks 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
Zirmul Bricks 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.
