Vacuum Induction Melting Casting Furnace

An induction furnace containing a refractory lined crucible surrounded by an induction coil is located inside a vacuum chamber.

Vacuum induction melting casting furnace.

The melting and casting operations are carried out at low pressures to control the entire alloy chemistry process. Since that time a variety of vim furnaces with capacities from 1 up to 30 t have been designed engineered and delivered to leading specialty steel and alloy producers throughout the world. In 1928 the first industrial scale vacuum induction melting and casting furnace was engineered and manufactured by ald s parent company and then commissioned in hanau germany near today s ald headquarters. Vacuum induction melting and casting is the most commonly used process in secondary metallurgy to melt solid metal feedstock to refine the metals while in the liquid state and to adjust the chemical composition.

Induction furnaces and melting from induction heating to vacuum induction melting ecm technologies is a historic actor in the induction sector. Vim involves placing a core less induction furnace into a vacuum chamber. The technology is the perfect combination of vacuum technology smelting technology and casting technology. Retech s market dominance is predicated upon intelligent design including precise and reliable heating recipe driven controls data acquisition as well as effective manufacture processes.

Our typical mold sizes are 1 1 5 2 and 3 diameter by approximately 10 in length as well as a 1 5 thick by 5 5 wide by 11 tall slab mold. Vacuum induction melting the research vacuum induction melt vim furnace can cast weights of up to 20 pounds of iron nickel or cobalt based alloys. Vacuum induction melting vim is the melting of metal via electromagnetic induction under vacuum. Vim is used in particular for producing alloys with melting points beyond those practical for other kinds of melting.

In the early 90s ecm technologies and cfei previously saphymo cell both members of the dynathermic group proposed heat treatment installations under vacuum and under controlled atmosphere. Vacuum casting furnace description. The process of melting with a vacuum casting machine. Vsg induction heated vacuum melting and casting systems from pva are cold wall furnaces made of corrosion resistant stainless steel with water cooled double jackets.

From 1 to 30 tons. Vacuum induction melting vim over 40 years retech vacuum induction melting vim furnace equipment has proven to consistently deliver value and competitive advantage for our customers through a combination of system innovation and a focus on each customer s specific needs. It is important to note that a vacuum induction melting furnace provides a non contact melting process i e the molten metal does not have a direct contact with the heating coil therefore making the molten metal to have no contamination. Refers to the production process of forming the final product in a vacuum environment by melting or casting the metal by induction or arc heating into a pre cast casting mold.
