The muffle tube is a core component of mesh belt atmosphere furnaces, responsible for isolating the heating zone from the external environment, maintaining stable process atmosphere, and ensuring uniform heating of materials. It directly influences the furnace's temperature resistance, corrosion resistance, and service life, making it critical for high-quality material processing.
Key Materials
1. SUS310S
A high-temperature resistant austenitic stainless steel with excellent oxidation resistance and creep strength.
Can withstand continuous operation at temperatures up to 1150℃, suitable for most medium-to-high temperature atmosphere processes (e.g., annealing, sintering, and drying).
Features good corrosion resistance to general oxidizing and reducing atmospheres, with stable performance and cost-effectiveness for conventional industrial production.
2. Inconel 601
A nickel-chromium-iron alloy designed for extreme high-temperature environments.
Boasts superior high-temperature resistance (continuous service temperature up to 1250℃) and exceptional oxidation resistance, even in harsh atmospheres like high humidity or slight corrosion.
Offers excellent thermal stability and creep resistance, ideal for precision processing of special materials (e.g., aerospace components, high-performance ceramics) and complex atmosphere heat treatment processes.
Core Functions & Advantages
Atmosphere Isolation: Effectively separates the internal process atmosphere (e.g., nitrogen, hydrogen, argon) from air, preventing oxidation or contamination of materials.
Uniform Heating: The tube’s material ensures good thermal conductivity and temperature uniformity, avoiding local overheating of workpieces on the mesh belt.
Durability: Both SUS310S and Inconel 601 have strong mechanical strength at high temperatures, resisting deformation and extending the component’s service life.
