Product introduction

1500 Functional Module is a high-end modular furnace lining product made by adding chromium trioxide (Cr₂O₃) to standard high-purity ceramic fibers through a special process. It is not simply a mixture of materials, but an optimization of the fiber matrix with the chromium (Cr) element, significantly enhancing its corrosion resistance, reduction resistance, and structural stability at high temperatures. This product is made from high-quality 1500 functional fiber blankets, folded, compressed, and embedded with an anchor system, with a long-term operating temperature of up to 1350℃, making it an ideal “functionally enhanced” choice for harsh high-temperature conditions.

Product Features

1.Excellent resistance to chemical erosion

·The introduction of Cr₂O₃ greatly improves the resistance of the module to reducing atmospheres, acidic flue gas and alkaline steam (e.g. potassium and sodium oxides).

·In an environment where corrosive gases are present such as petrochemical cracking and non-ferrous metal smelting, it can effectively slow the deterioration of fibers, prevent the powderification of furnace liners, and extend the service life by more than 30%.

2.Excellent high temperature stability and low contraction rate

·The Cr component helps to form a more stable crystal structure at high temperatures, allowing the module to maintain a very low heating permanent line change at 1400℃ (usually ≤ 3%).

·Ensure that furnace liners remain structurally tight after long-term high temperatures, producing no gaps, maintaining excellent sealing and insulation integrity, and avoiding local overheating.

3.Excellent airflow resistance and structural strength

·The unique folding and compressing process allows the fiber direction to be perpendicular to the furnace wall, combined with the dense structure, giving the module high tensile strength.

·It can effectively resist high-speed heat flow swerving and prevent the ceiling from sagging and deformation due to high temperature and self-gravity, especially suitable for kilns that require high-speed smoke removal.

4.Significant energy saving and economic benefits

·The extremely low heat conduction coefficient (1000℃≈0.149W/m·K) effectively blocks the heat loss, significantly reduces the furnace temperature, and the comprehensive energy saving rate can reach 20% -40%.

·The low heat capacity enables the furnace to heat up and the rate of cooling faster. It is especially suitable for intermittently operated furnaces.

Typical Technical Parameters

Typical Application

The 1500 Functional Module is specifically designed for harsh operating conditions involving chemical corrosion and extremely high temperatures, and is widely used in various applications:

·Petrochemical Industry: Tube furnaces such as ethylene cracking furnaces, hydrogen production conversion furnaces, and reforming furnaces, which have extremely high requirements for the resistance of the furnace lining to reducing atmospheres.

·Steel metallurgy: high-temperature annealing furnaces, covered furnaces, and annealing furnaces, particularly suitable for thermal treatment lines where a protective or carburizing atmosphere is present.

·Non-ferrous metals: aluminum smelting furnaces, copper and copper alloy melting furnaces, zinc evaporation kilns, designed to effectively resist corrosion from metal vapors.

·Ceramics and Building Materials: The firing zone of high-temperature tunnel kilns and roller kilns, as well as areas within the kilns where alkaline volatile substances are present.

·Environmental Protection and Waste Incineration: The secondary combustion chamber of the waste incinerator, boiler insulation, and ability to withstand the complex chemical composition of flue gases.

Summary

The 1500 Functional Module is not only a thermal insulation material, but also a systematic solution for the longevity, high efficiency and energy saving operation of industrial kilns. Through the precise addition of Cr₂O₃, it successfully solves the pain point of short life of traditional ceramic fibers in corrosive atmospheres.

Choosing the 1500 Functional Module means you have chosen a reliable "guardian" for the kiln, which will provide a solid guarantee for your productivity with longer life, more stable operation and lower integrated energy consumption.
