ITPA induction melting furnaces are mid-frequency furnaces operating in the 2400 to 500 hertz range. A series of induction ITPE type mid-frequency furnaces developed by our specialists is an improved and modernized version of ICT furnaces. Due to the use of new materials and technologies in the manufacture of the furnace efficiency increased by more than 10% compared to ICT.
For example, the ITPE furnace frame is made of non-magnetic stainless steel, IST has an aluminum frame that causes it to break down when a small amount of melt comes in. wire and argon – arc welding.
In ICT, as a busbar from a capacitor bank to an inductor, an aluminum bus with air cooling is used, we also manufacture it from a water-cooled copper conductor that has low and stable resistance at elevated ambient temperatures. All these innovations provide low circuit losses in the transmission of electricity from a capacitor bank to the inductor of the furnace.
A higher-quality frequency converter of the fifth generation is manufactured on the newest element base, which ensures its trouble-free operation. It makes no sense to list all the changes we have made, all these changes in the complex provide significant energy savings and, as a consequence, a reduction in production costs. The quick smelting mode provides low metal waste, uniform melt temperature throughout the crucible volume, smelting in any given temperature mode, high performance.
As in furnaces of type ITPE, it is possible to melt both open and inert gases, a wide range of metals and their alloys, cast iron, various alloyed steels, copper, aluminum, titanium, etc. The control system automatically maintains the melting mode selected by the operator.
Electric furnaces such as IST are designed to work in the following conditions:
To determine the actual performance of the furnace, the consumer must take into account the time spent on the introduction of alloying additives, refining, metal drainage, as well as the technology of melting, the type of charge and how it is loaded, and other necessary technological operations.
