HM-4-17A Vacuum Tube Furnace

Product Introduction

HM-4-17A is a vacuum tube furnace for universities, scientific research institutes, and industrial or mining enterprises that need high-temperature material treatment with controlled gas or vacuum-tube operation. The furnace accepts a high-purity quartz or high-purity alumina corundum tube, with horizontal or vertical installation available across the documented series. This model uses a Φ40*440 furnace size (excluding tube length), a 1700°C maximum temperature, 5kw power, and 220V supply. The 1700°C series uses silicon molybdenum rod and a B-type (0-1820°C) measurement system. Single-, double-, three-, or five-zone configurations can be selected at equipment level, while a rotating and tilting system can also be added to the furnace body. An intelligent controller supports 30-50 segment programmable PID self-tuning, automatic heating, and automatic cooling. Inlet gas control, a vacuum gauge, a vacuum pump, and 304 stainless-steel flanges support the documented atmosphere-oriented heating work. Compare the HM-4-17A product page when planning tube size, temperature class, and installation.

Applications / Testing Items

• Atmosphere-protected sintering for 1700°C-class material work.
• Atmosphere reduction studies in universities and scientific research institutes.
• Ceramic and refractory-material development with controlled heating.
• Metallurgical, electronic, glass, chemical, and mechanical material research.
• New-material development, special-material work, and building-material research.
• Small-batch production and teaching within the documented application scope.

Functional Performance / Features

1. This configuration reaches a maximum temperature of 1700°C and has a documented operating temperature of ≤1550°C.
2. HM-4-17A uses a Φ40*440 furnace size (excluding tube length).
