1. Retain the native dense layer to maximize erosion resistance
→Optimal primary surface layer: After cooling by electric melting AZS casting, a dense, low porosity, and defect free primary surface layer is formed on the working surface (with a porosity close to 0), which is the area with the strongest resistance to glass liquid/slag erosion.
→Processing damages the protective layer: Mechanical processing (cutting, polishing) will remove this dense skin layer, exposing the relatively loose substrate inside, directly reducing the corrosion resist.
→Reduce glass liquid pollution: The original surface is purer, without processing microcracks and dust residue, reducing the risk of stones and bubbles in the glass liquid, and ensuring the quality of high-end glass.
2. Avoid processing damage, improve thermal shock and structural stability
→Eliminating processing stress: AZS has extremely high hardness (Mohs 9), which can easily cause microcracks, hidden cracks, lattice distortions during processing, and can easily expand at high temperatures, leading to explosions and peeling.
→Maintain overall strength: Without processing, the original structural strength and thermal shock stability of the brick can be fully preserved, reducing safety hazards during kiln operation.
→Reduce shrinkage/porosity exposure: Processing may cut into internal shrinkage and porosity areas, forming erosion channels. Without processing, avoid these weak points.
3. Significantly reduce costs and increase efficiency, shorten delivery cycles
→Save processing costs: AZS processing requires specialized diamond/hard alloy cutting tools, a large amount of coolant, low efficiency, high tool wear, and high energy consumption. Not processing can save all processing costs.
→Reduce material loss: Processing allowance (3-10mm) will result in high-value AZS material waste, without processing, there will be zero loss.
→Shorten production cycle: eliminate cutting, polishing, inspection and other processes, deliver faster, and adapt to the needs of kiln repair and rapid production.
4. Simplify construction and improve masonry quality
→Reduce on-site maintenance: The flatness and dimensional accuracy of the original working surface are controllable, and there is no need for secondary processing on site, reducing construction difficulty and dust pollution.
→Optimize the sealing of brick joints: Retain the natural casting surface, make the brick joints easier to seal, reduce the risk of material leakage and fire, and improve the airtightness and thermal efficiency of the kiln.
