Bangladeshi customers required silicon bricks for glass furnace

Bangladeshi customers recently inquired about refractory bricks for glass kilns. The customers expressed a desire to purchase a batch of refractory bricks for their glass kilns from our factory. Our technical team selected silicon bricks for the customer.

Glass kilns operate in harsh environments, consistently operating at temperatures above 1600℃, and must withstand the erosion of molten glass and temperature fluctuations. Silicon bricks, due to their numerous superior properties, have become the preferred material for constructing glass kilns, offering significant advantages and perfectly meeting production requirements.

Silicon bricks exhibit outstanding high-temperature resistance, with a silica content exceeding 95%. Their refractoriness exceeds 1710℃, and their softening temperature under load is close to their refractoriness. They maintain structural integrity under the high-temperature conditions of glass kilns, without softening or disintegrating, thus meeting the high-temperature requirements of the molten pool. Furthermore, their excellent high-temperature volumetric stability, with a reheat linear shrinkage rate controlled within a reasonable range, prevents cracks caused by thermal expansion and contraction, ensuring the kiln’s structural airtightness.

Silicon bricks possess excellent chemical stability, sharing the same main components as glass. The substances produced after erosion can dissolve into the molten glass, preventing defects such as stones and streaks, thus avoiding contamination of glass products and improving product quality. Furthermore, silicon bricks have reasonable thermal conductivity, effectively transferring heat and ensuring a uniform and stable temperature within the kiln, reducing heat loss and lowering energy consumption in glass production.

Silicon bricks also offer economic advantages. The raw materials are readily available, the manufacturing process is relatively simple, and the cost is lower than high-end refractory materials. They also have a long service life, reducing the frequency of kiln maintenance and material replacement costs, balancing practicality and economy, and fully meeting the long-term stable production needs of glass kilns.

Through the technical team’s explanation, the customers ultimately chose silicon bricks. The technical staff and the customers finalized the solution and proceeded to the next stage of communication.
