1. Manufacturing of continuous caster rolls, hardfacing and refurbishing of the welding surface of the rolls by welding.


We manufacture component parts and segments of continuous casting machines produced by SIEMENS-VAI (Austria), SMS-DEMAG (Germany), Daniely (Italy).
We also manufacture assembled rolls and component parts: bands, bearing supports, bearing cap rings, (rotary) swivels.

We manufacture and refurbish rolls of radial, bow and horizontal segments of continuous casting machines. The rolls are manufactured of heat-resistant steel, hardness of the body is 197-269HB. The working surface of the roll is hardfaced by nitrogenated materials, the material hardness is 44-47HRC.

Advanced technologies and high quality welding materials are used at hardfacing process, this helps to avoid net shaped roll marks, to reduce mechanical wear and corrosion wear. The output of cast metal produced in overhaul period exceeds 500 000tons at the vertical part of continuous casting machine and it is up to 5mln. tons at the horizontal part. The working surface of the rolls is resistant to hydrofluoric acid. Due to specific design and mechanical properties the service life of such rolls exceeds the service life of rolls of common design 5 times as much. The total lifetime of Segment no.3 (set with the rolls made by Autospecmach Ltd.) of CCM no.5 installed at iron-and-steel company Severstal comes to more than 3000heats. The lifetime rolls without hardfacing comes to 600-800heats.

2. Refurbishing and hardfacing of forming rolls

Our company refurbishes:

2.1. Hot-rolling mill rolls made of steel grade 9ХФ, СПХН. The medium-carbon chromium materials with hardness of the working surface equal to 53-57HRC are used for hardfacing. Due to this technology the lifetime of rolls increases 4.5 times as much.

"Scrapped hot rolling mill rolls before machining for welding"  

2.2. Cold-rolling mill rolls made of steel grade 9Х, 9ХФ. The hardfacing is carried out with high-carbon chromium materials, the hardness of the working surface is 58-62 HRC. Due to this technology the lifetime of rolls is 2.5 times increased.

3.Refurbishing of sheet-rolling mill rolls and profile shaping rolls, hardfacing of the working surface by welding

Our company refurbishes:

3.1. Sheet straightening machine rolls made of steel grade 9X. The hardfacing of the working surface is carried out with high-carbon chromium materials, the hardness of the working surface is 58-62HRC.

3.2. Profile-bending machine rolls made of steel grade 9X. The hardfacing of the working surface is carried out with high-carbon chromium materials, the hardness of the working surface is 58-62HRC.


3.3. Rolls for coil winding equipment and sheet working machines. The working surface is hardfaced with nitrogen-containing austenitic materials with the hardness of 44-47 HRC.

4. Hardfacing of circular-shaped and flat surface of new parts

Hardfacing of sinter and coke production equipment, which works at normal and high (up to 1200°) temperatures and is subject to high abrasion wear.
"Hardfacing of sinter stars, fire bars and knives"  

"Hardfacing of replacable parts of disc and hammer crushers (of coke production equipment)"  

5. Reconstruction of geometry of used parts by welding

  • Refurbishing of roll shafts made of steel grade 9ХФ.


  • Refurbishing and repair of press-forging component parts dies of cold and hot forging, matrixes, hammer heads, etc.)


  • Refurbishing and hardfacing of feeding segments of hardware production

6. Other welding and cladding operations

  • Repair welding
  • Repair works at Customer’s site without demounting of the equipment
  • Refurbishing of cast iron component parts
  • Engineering and work material selection

7. Sleeving of rolls

The refurbishing of CCM bow and horizontal segment rolls by sleeving protects against net shaped roll marks on the surface of the roll barrel, and increases lifetime of the roll. Multiple repair of rolls by sleeving extends their lifetime many times and ensures 40% reduction of repair and maintenance costs compared to traditional methods of repair.
Our company produces rings, which are used for roll sleeving. The patent has been acquired for the technology of sleeving.

8. Manufacturing of rolls from forged pieces
