Rocking motion furnaces have been in use for many years, over time the applications have increased for both melting and processing as well as ferrous and non-ferrous metals and alloys. Additionally, certain chemical and other operations on both metallic and non-metallic materials have found using rocking motion ovens advantageous.
Rocking/Oscillating Motion Ovens and Furnaces
How do Rocking Motion Ovens Work?
Some rocking motion ovens are indirect arc types that have two horizontal electrodes and make use of automatic mechanical rocking which leads to a controlled stirring of the charge throughout the heating process. It also means there are unique features for melting and superheating and operations are extremely beneficial.
Uses of Rocking Motion Ovens
Rocking motion ovens are often used for melting charges which are made up of pig iron or ingots, foundry returns, and scrap. They are also extremely well suited to adapting to the melting of charges made up of borings, turnings, and other finely divided material.
The overall range of operations is extremely broad; in the non-ferrous field most types of brass and bronze product in commercial and domestic use is denoted.
In ferrous melting, rocking motion ovens are widely used because there are specific advantages for manufacturing products that need high-quality, close control, or unusual characteristics.
Gray Iron
Rocking motion ovens can be used to produce gray iron that is close-grained, dense and thoroughly uniform. The iron can be composed in an exact, predetermined manner allowing for repeatability.
Because there is no protective slag covering necessary on the bath, there is extreme accuracy of control over the composition, allowing for the gray iron to be produced at the highest quality.
High-Alloy Irons
As heat-resistant irons tend to be alloyed, the rocking motion furnace manufactures them with extreme economy. The melting loss is unusually low, meaning the rocking motion ovens can lead to a full recovery of alloys within the foundry returns.
Stainless, Heat-Resistant, and Alloy Steels
The rocking motion oven uses two standard techniques for manufacturing alloy steels: compounding and remelting. Rocking motion ovens are entirely free from slagging operations and oxidizing influences because of the indirect arc principles, meaning the oven can melt and remelt the alloys without carbon pick-up or losses in the alloying elements.
Rocking Motion Ovens from Deltech Furnaces
At Deltech Furnaces, we manufacture rocking motion ovens that are specifically built to suit each customer’s design needs. With operating temperatures up to 1600 degrees Celsius, Deltech furnaces are employed in applications such as melting and stirring glass in ampoules then quenching the ampoules rapidly. Our rocking motion furnaces are laboratory size, used for research, and for applications such as containing nuclear waste in glass.
