The core reason is that the bricks for the superstructure are used "vertically," allowing us to maximize their strengths and minimize their weaknesses through design and construction. a) Performance Matching and "Making the Most of Resources" Erosion of the glass furnace's superstructure (such as the arch and breast wall) primarily originates from the gas phase and dust inside (hot side). Erosion is unidirectional, progressing from the surface inwards. During construction, the "dense part" of regular-casting-AZS-brick faces inwards (hot side), directly confronting the corrosive medium. This ensures that the most erosion-resistant portion is used where it is most needed. Meanwhile, the relatively weaker "loose part" is placed on the outer (cold side), where the temperature is lower and it is almost unaffected by erosion; its poorer performance does not impact the overall service life. b) Maximizing Cost-Effectiveness The inclined casting process is complex, requiring special molds and precise cooling control, resulting in a relatively low yield. Therefore, it is very expensive, typically 30%-50% or more more expensive than ordinary cast bricks of the same material. hashtag#AZS_REFRACTORYhashtag#SUPERSTRUCTUREhashtag#GLASS hashtag#REGULAR_CASTINGhashtag#WShashtag#PThashtag#VFhashtag#RChashtag
