Electrical Discharge Saw(EDS) Used for ESR Ingots Cutting at a Super Fast Speed.

Electroslag remelting (ESR), is also known as electro-flux remelting, is a process of remelting and refining steel and other alloys for mission-critical applications in aircraft, thermal power stations, nuclear power plants, military technology, etc. And the refining steel and other super alloys are too hard to be cut with normal band saw cutting off machine.

How to cut these hardened material bars, especially the larger diameter bars? To solve this problem, we have developed a new electrical discharge sawing machine(EDS). The EDS machine can be used to cut these super hardened material at a fast cutting speed: 1800 square mm per min( on the cut off cross section).

Job of EDS machine

ESR ingots

One new Electrical discharge sawing machine is installed successfully in our client’s workshop in India in October of 2018.  And it is used to replace the band saw machines for cutting the refining ESR ingots. Here is one of the cutting test results at our client’s place as following:

1. Job: electroslag refining special steel of dia540mm.

2. Cutting off time: 117minutes.

3. Speed: 1950 sq mm/min.

Attached please find some pictures of the EDS machine in our client's workshop for your reference.

If you are special steel makers and have a lot of larger ESR steel bars or to cut, the electrical discharge sawing machine is the best cutting machine tool for you.
