In the petrochemical industry, high-temperature furnaces such as cracking furnaces, reformers, and process heaters operate under extreme conditions, including direct flame exposure, high-velocity heat flow, and frequent thermal cycling. Traditional hot-face lining materials—such as lightweight refractory bricks and standard ceramic fiber products—often suffer from surface spalling, fiber shedding, excessive dust, and installation challenges. These issues reduce insulation performance, increase maintenance costs, and pose operational safety risks.

To address these challenges, CCEWOOL has developed the Ceramic Fiber Back-lining Board, specifically designed for hot-face applications. As a high-performance ceramic insulation board, it features enhanced resistance to heat flow erosion and superior structural integrity under extreme temperatures. Even when exposed directly to combustion zones, the board maintains its shape without powdering or degradation, significantly extending the durability and safety of hot-face lining systems.

These performance advantages are made possible by CCEWOOL's advanced manufacturing processes. We utilize multi-stage refined alumina raw materials, combined with high-pressure vacuum forming and intelligent temperature-controlled sintering, followed by surface hardening treatment. This results in a dense, smooth surface and uniformly bonded fiber structure, which drastically improves resistance to thermal erosion and mechanical impact. The boards are also clean-cut, layer-free, and produce minimal dust on-site, ensuring safer and more efficient installation.

In real-world petrochemical applications, this ceramic insulation board is widely used in the hot-face linings and furnace roof structures of cracking and reformer units. Customer feedback indicates that after replacing traditional linings with CCEWOOL ceramic insulation boards, fiber shedding was eliminated, maintenance intervals extended by over 30%, and system efficiency improved significantly. The reduction in airborne fiber and dust also prevents downstream contamination of catalysts and sensitive equipment, resulting in safer and more cost-effective operation.

CCEWOOL continues to drive innovation in ceramic insulation board manufacturing with industry-leading capabilities and deep application expertise—delivering safer, more efficient, and more reliable hot-face insulation solutions for the petrochemical sector.
