In the fast-growing photovoltaic and silicon material industries, high-temperature heating performance directly affects production efficiency, product yield, and equipment stability. Diffusion furnaces, annealing furnaces, and crystal heat treatment furnaces operate continuously above 1300℃, placing extremely high requirements on electric heating systems and heating material reliability. Conventional FeCrAl wire often shows rapid oxidation, severe deformation, resistance drift, and short service life under ultra-high temperature conditions, causing frequent shutdowns and high maintenance costs. The HRE high-temperature heating wire developed and produced by Beijing Shougang Gitane New Materials Corporation is a patented resistance wire solution designed for ultra-high temperature electric heating applications, providing stable and long-lasting material support for photovoltaic and silicon manufacturing lines worldwide.
As a high-performance FeCrAl wire grade, HRE alloy uses a unique micro-alloy design and high-purity metallurgical process to achieve outstanding stability in high-temperature heating environments. With a maximum operating temperature of 1350℃, HRE heating wire fully meets the strict ultra-high temperature requirements of silicon wafer processing and crystal heat treatment, effectively solving the problems of insufficient heat resistance and rapid aging of ordinary heating material. Its resistivity is stably controlled at 1.45±0.07 μΩ·m with a resistance tolerance within ±5%, ensuring uniform temperature distribution and precise control of the electric heating system, which helps improve batch stability and final product quality. During long-term high-temperature service, HRE resistance wire provides much better oxidation resistance than standard FeCrAl wire, with a 1350℃ rapid life exceeding 80 hours, high-temperature strength of 20 MPa, and elongation over 14%. These properties greatly reduce the risks of deformation, fracture, and premature aging of heating wire in harsh working conditions.
HRE heating material offers a complete range of dimensions: round wire from φ0.1mm to φ9.0mm and flat strip from 0.5mm to 2.5mm thickness, supporting diversified structural designs for high-temperature heating equipment. Whether used in continuous heat treatment furnaces or intermittent diffusion furnaces, HRE FeCrAl wire maintains stable heating performance and strong durability, supporting uninterrupted long-term operation of photovoltaic production lines. Compared with ordinary resistance wire, HRE significantly extends service life, reduces maintenance frequency, and lowers the total cost of ownership for industrial electric heating systems.
With continuous expansion and technological upgrading in the global photovoltaic industry, demands for high-temperature heating and high-performance heating material keep increasing. HRE patented FeCrAl wire has become the preferred heating wire for high-end electric heating systems in the photovoltaic and silicon material sector due to its stable performance, strong high-temperature resistance, and reliable supply capacity. Choosing SPARK HRE means more stable high-temperature heating, higher production efficiency, and more controllable material costs, helping global manufacturers enhance competitiveness and achieve sustainable production.
