Tungsten Molybdenum Heating Screen | High Temperature Furnace Heating Element

Tungsten-Molybdenum Heating Screen

Tungsten-molybdenum heating screens are core insulation and heating components in the heating chamber of vacuum furnaces. They are primarily made of high-melting-point metals such as tungsten and molybdenum, and feature high temperature resistance, low vapor pressure, strong oxidation resistance, and good thermal stability.Tungsten-molybdenum heating screens are widely used in vacuum heat treatment furnaces, vacuum sintering furnaces, vacuum melting furnaces, and high-temperature experimental equipment. They effectively reduce heat loss, improve furnace temperature uniformity and thermal efficiency, and ensure stable processing of products under high-temperature vacuum conditions.

Caratteristiche del prodotto

1. Ultra-High Temperature Resistance

Made with high-melting-point metals such as tungsten and molybdenum, it can withstand long-term high-temperature operation in vacuum or protective atmosphere environments, meeting the requirements of high-temperature sintering, trattamento termico, and other processes.

2. Excellent Thermal Insulation

The multi-layer structure design reduces heat radiation loss, improves furnace thermal efficiency, reduces equipment energy consumption, and enhances furnace temperature stability.
