Jiugang 1080 m³ Hot Blast Stove Project
When Jiugang Iron & Steel Group (酒钢集团) needed to engineer their flagship 1080 m³ hot blast stove, they turned to CH Refractories. Our 3D CFD flow simulation-driven engineering achieved 15+ years of verified service life and uniform heat distribution across the checker chamber.
Engineering Approach & Key Results
Prior to installation, our engineering team conducted 3D CFD (Computational Fluid Dynamics) flow simulations to verify thermal performance, optimizing combustion efficiency and ensuring uniform heat distribution within the regenerator. This refractory engineering project achieved long service life through high-alumina bricks for the crown and combustion chamber, silica bricks for regenerator checker bricks, and andalusite bricks for the transition zone.
Fujian Dingxin Hot Blast Stove Project
Fujian Dingxin Steel’s (福建鼎信钢铁) hot blast stove refractory engineering project required customized 3D CFD simulation with optimized checker brick arrangement, delivering 15+ years of verified service life and stable blast temperature performance.
Engineering Approach & Key Results
Tailored to Dingxin’s specific operating conditions, we validated the optimal checker brick arrangement and combustion chamber design through customized 3D CFD simulations. This refractory engineering project demonstrates our capability to deliver standardized solutions that meet strict budget requirements while ensuring long service life.
The optimized lining design incorporates high-alumina bricks, silica bricks, and andalusite bricks. Featured refractory products include high-alumina brick for the combustion chamber crown, silica brick for regenerator checker bricks, and andalusite brick for the transition zone — all engineered for high-temperature stability and extended campaign life.
Ladle Refractory Engineering Project
A major steel mill needed a complete ladle working layer refractory engineering project. Our Solidworks-based 3D thermal simulation identified critical wear areas, leading to optimized material selection for slag line and bottom impact zones — reducing refractory cost by 30% and downtime by 30%.
Engineering Approach & Key Results
Through the establishment of Solidworks 3D model analysis, this refractory engineering project reduced the cost of ladle refractory and the difficulty of masonry operation. We accurately grasped the simulation of refractory materials in various parts of the ladle, and formulated reasonable ladle refractory material distribution and detailed material improvement programs.
The application of Solidworks 3D software for solid modeling and simulation analysis greatly improved the efficiency of actual drawing and the accuracy of design drawing — ensuring perfect fit, optimized material selection, and long service life for slag line, sidewall, and bottom impact zones.
Nonferrous Metal Smelting Project
JiTie Ferroalloy (吉铁铁合金) commissioned a refractory engineering project featuring our low-nitrogen combustion sleeve burner technology with custom refractory engineering. Our fluid analysis service identified optimal material selection for each thermal zone, ensuring long service life under aggressive chemical attack from molten metals and slags.
Engineering Approach & Key Results
In terms of energy saving and environmental protection, this refractory engineering project requires combustion equipment to achieve high-efficiency and controllable complete combustion. Our engineering team effectively reduces nitrogen oxide (NOx) generation in the combustion process, achieving high efficiency, energy saving, and environmental protection goals.
By adopting our low-nitrogen combustion sleeve burner technology, we properly control combustion temperature and effectively reduce nitrogen oxide emissions while reducing fuel consumption and investment. This refractory engineering project ensures long service life under the most aggressive chemical attack from molten metals and slags.
Composite Refractory Brick Engineering Project
A major iron & steel facility required arefractory engineering project for composite bricks used in blast furnace tuyeres and three-fork zones. Our Solidworks 3D modeling + Flow Simulation delivered precision pre-masonry assembly with 100% dimensional accuracy and zero on-site issues.
Engineering Approach & Key Results
Composite brick technology is a general design of refractory masonry for high-temperature kiln protection or thermal equipment. This refractory engineering project transformed the complex space geometry formed by the intersection of simple geometry into dozens or hundreds of refractory bricks with complex shapes.
Based on the modeling of Solidworks, the flow simulation was used for numerical simulation, and the results were used to test the performance of the designed kiln. These complex-shaped refractory bricks are interlocked with each other and reasonably transmit stress to form a solid and stable masonry — ensuringlong service life and100% dimensional accuracy for blast furnace tuyeres and three-fork zones.
