Location

Centromet AD is situated in the North West part of Bulgaria, in the city of Vratsa

110 km from Sofia by road1,5 hours by car

90 km by car from the Danube river

Company history

1977 – The company is establish with main scope of activities – centrifugal casting of high alloyed Cr-Ni based steel and alloyed cast iron

1989 – Due to the political situation in 1989 Centromet was reorganized and started producing unique products mainly for the European market:• Tubes and tube assemblies for the chemical industry• Furnace rolls• Cylindrical liners for 4-stroke diesel engines• Bimetalic roller shells The factory’s production is unique and specific to the client demands. The products are certified by LR, TUV and Intertek.

1999 – The company is privatized by Metal Technology Group Angel Balevski Holding AD. Since then Centromet AD is a member company of MTG

2007-2009 – Two new machines type Mazak are bought and the complete manufacturing of cylindrical bushings WASA 46 is approved

2009-2014 – Two new installations are constructed and approved for vertical centrifugal casting of cylinder liners WASA 46 and large bimetallic rolls with diameter up to 1200 mm.

2014-2017 – a new three year project was started for production of bimetallic rolls with high Cr content

2018-2019 – new induction furnaces are bought (5 in total)

2019 – Poreba CNC turning lathe is put in operation, 3D measuring arm is bought
