The main production facilities of PSM are the following:

Melting:
Melting is done in water cooled vertical walled two 15 ton capacity Electric Arc Furnaces (EAF).

Refining:
Refining is done in Ladle Furnace with gas purging, and / or Vacuum Degassing (VD) or Vacuum Oxygen Degassing (VOD).

Secondary Refining:
Secondary refining is done in the Electro-Slag Remelting (ESR) Unit with an output of 320 to 600 mm diameter ingot. The ingot thus produced has:

• Uniform structure with virtually no internal faults and least micro segregation.

• Very low level of harmful impurities and trace elements.

Ingot Casting:
Highly refined ingots in rectangular, round and square sections are produced by bottom pouring technique. Ingot sizes vary from 500 kg to 2000 kg depending on steel grade and initial stock size requirement. Ingots can be slowly cooled, stress relieved or annealed.

Continuous Casting:
A twin strand continuous caster unit equipped with soft secondary cooling, two stage magnetic stirring and other special features is used to produce 110 to 150 mm square or round billets in special steel grades.

Steel Foundry:
The PSM foundry is equipped with a 500 kg induction melting furnace and shot blasting machine. Up to 350 kg of alloy steel castings are prouced through box moulding technique, and much heavier castings are pit moulded.

Blooming & Slabbing Mills:
Plate width up to 1350 mm and thickness down to 12 mm can be rolled from flat ingots. Round and square section sizes from 100 mm to 200 mm can also be produced. The Blooming Mill is also equipped with controlled atmosphere reheating furnace, and roll cutting / grinding facilities.

Bar Rolling Mill:
The mill can roll round and square section sizes from 60 to 12 mm, flats from 120 to 40 mm width and 20 to 6 mm thickness. The shop is also equipped with controlled atmosphere, pusher type reheating furnaces, and roll cutting / grinding facilities.

Hammer Forging:
PSM has one, two, and three and a half ton forging hammers. Hammer forging facility is versatile in the sense that it can be used for either breaking down the cast structure of ingot or for free or die forging, depending on the steel grade and requirement. The weight of forging can vary from 5 kg to 2000 kg. Hammers are air drop type which are supplemented with mechanical presses, reheating and heat treatment furnaces.

Rotary Forging:
Rotary forging is the state-of-the-art technique in forging through short blow triaxial hammering to ensure internally sound high integrity forged square, flat or round shafts in stepped or stepless dimensions. The section size can vary from 60 to 200 mm.
