Salahärdarnas vacuum department has expanded its oven park with an Ipsen Turbo Treater MFV 12 bar. Oven meter B 610, H 610, L 900 Charger, weight up to 800 kg.
With our new oven and highly skilled staff, we are the market leader in vacuum hardening. No jobs are too difficult for us.
A vacuum oven is a type of oven that can heat materials, usually metals, at very high temperatures, and carry out processes such as soldering, sintering and heat treatment with high consistency and low degree of pollution.
In a vacuum oven, the product is surrounded by a vacuum. Absence of air or other gases prevents heat transfer with the product by convection and removes a contamination source.
Some of the benefits of a vacuum oven are:
• Uniform temperatures in the range of 1100-1500 °C.
• The temperature can be controlled within a small area.
• Low contamination of the product by carbon, oxygen and other gases.
• Quick cooling (cure) of the product.
• The process can be computer controlled to ensure metallurgical repeatability.
Heating of high temperature metal usually results in rapid oxidation, which is inappropriate. A vacuum oven removes oxygen and prevents this from happening.
A noble gas such as argon is usually used to rapidly cool the treated metal back to non-metallurgical levels according to the desired process in the furnace. This sluggish gas can be pressurized to two or more atmospheres or more through the hot zone to pick up the heat before it passes through a heat exchanger to remove heat. This process is repeated until the desired temperature is reached.
