Product Description

Corundum Furnace Tubes – High-Performance Refractory Solutions for Extreme Environments

Product Overview

Corundum furnace tubes are premium-grade refractory components engineered for ultra-high-temperature industrial applications. Composed of high-purity α-alumina (Al₂O₃ ≥ 90%, up to 99% in advanced grades), these tubes are manufactured through high-temperature sintering or electric melting, with optional additives like chromium oxide (Cr₂O₃) and zirconium oxide (ZrO₂) to enhance thermal shock resistance, erosion durability, and mechanical strength.

Mingte’s corundum furnace tubes are designed to withstand temperatures up to 2050°C, making them ideal for metallurgical, chemical, ceramic, and glass industries where extreme heat and corrosive conditions prevail.
