Conductance & Throughput in Vacuum Pipelines

A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents oxidation, heat loss from the product through convection, and removes a source of contamination.

The vapor pressure of a material is that pressure exerted at a given temperature when a material is in equilibrium with its own vapor. Vapor pressure is a function of both the material and the temperature. Chromium, at 760 torr, has a vapor pressure of ~4,031ยฐF. At 10ยฏ5, the vapor pressure is ~2,201ยฐF.

For vacuum furnaces, the heating elements are typically wide strips and ribbon-shaped to maximize both their physical and radiant surface areas. Metallic heating elements for high-temperature vacuum furnaces are commonly made of refractory metals (Fig. 1). Refractory metals are extremely high melting point metals that are resistant to wear.

A vacuum is one of the methods to protect heated steel and metal parts from the negative influence of an air atmosphere. A vacuum furnace is normally an electrically heated furnace in which a vacuum is maintained during the process. Most vacuum furnace are heated by electric resistance elements made from graphite, ceramics or metals.
