产品之三： 透气砖的必要性 Product three: The necessity of breathable bricks

在钢铁冶金行业的技术升级浪潮中，透气砖作为钢包精炼环节的"呼吸系统"，其性能直接决定了钢水质量与生产效率。2026年1月，国内某大型钢铁集团宣布与我公司达成战略采购协议，周全的升级其透气砖供应体系。这一决策不仅是对我公司技术实力的认可，更是钢铁企业追求高质量发展的必然选择。

一、行业背景：透气砖技术革新的迫切性
根据《2025年全球电炉专用透气砖行业总体规模分析报告》，全球透气砖产业规模已突破85亿美元，预计2026年将跨越百亿美元门槛。随着环保政策的持续加码，低导热系数、长寿命的高性能透气砖需求激增，2024至2030年复合增长率预计维持在7.8%的高位。

在国内市场，2025年中国钢包座砖透气砖市场的前五大生产企业占据了超过70%的市场份额，行业集中度进一步提升。然而，传统透气砖普遍存在使用寿命短、透气性不稳定等问题，平均使用寿命仅为150炉次左右，远不能满足现代高效炼钢的需求。
In the wave of technological upgrades in the steel and metallurgical industry, porous plugs, as the "breathing system" of the ladle refining process, directly determine the quality of molten steel and production efficiency. In January 2026, a large domestic steel group announced a strategic procurement agreement with our company to comprehensively upgrade its permeable brick supply system. This decision not only recognizes our company's technological strength but also represents an inevitable choice for steel companies pursuing high-quality development.
I. Industry Background: The Urgency of Technological Innovation in porous plugs
According to the "2025 Global Electric Furnace Permeable Brick Industry Overall Scale Analysis Report," the global permeable brick industry has exceeded US$8.5 billion and is expected to surpass the US$10 billion threshold in 2026. With the continued tightening of environmental policies, the demand for high-performance porous plugs with low thermal conductivity and long lifespan is surging, with a compound annual growth rate expected to remain high at 7.8% from 2024 to 2030.
In the domestic market, in 2025, the top five manufacturers of porous plugs for ladle seats in China accounted for more than 70% of the market share, further increasing industry concentration. However, traditional porous plugs generally suffer from problems such as short service life and unstable permeability, with an average service life of only about 150 heats, which is far from meeting the needs of modern high-efficiency steelmaking.
