Company description
METALURGICA TRANSILVANA AIUD PRESENTATION
Aiud is documentary attested since 1293. For more than two centuries, until 1929, it was the Capital town of the Downstream Alba County.
Transformed into a municipal city in 1994, Aiud has now 31.000 inhabitants.
The existence in the city, since the XVIIIth century, of a tradition in the locksmith and carpentry production organised in guilds, lead to the formation in 1894, of a locksmith and building materials???¬?? plant, which has developed in the present metalworking company.
In 1931 it was transformed into the ???¬?GENIUS???¬?? factory for technical products, with headquarters in Brasov, and since 1933 in Aiud is certified the existence of the ???¬?Engineer A. I. Stoica Technical Laboratory???¬?? which manufactures, besides pressed goods and metallic packages, equipment for the army???¬??s endowment.
In 1948, the factory has been reorganised and has functioned under the name of ???¬?Aiud???¬??s Rapid Factory???¬?? and had as manufacturing profile, pumps and equipment for fire brigades, locksmith tools, metallic wheelbarrows, simple agricultural machines, cast iron consumer???¬??s goods.
Since 1951, the factory was registered as a maintenance and repair workshop for rolling equipment, subordinate to the ???¬?Iron and Steel Company???¬?? Hunedoara, being reshaped on repairs for railway engines, freight cars, casting cars, mining cars and cable cars.
Consequently, at the end of 1954, the factory became a production unit with its own financial administration under the name of ???¬?Aiud???¬??s Metalworking Plant???¬??, having as manufacturing profile the rolling equipment???¬??s repair for the entire Iron and Steel industrial sector.
Starting with 1958, the plant specialises in spare parts, equipment, metallic structures manufacturing, for the Iron and Steel, Metalworking and Machines???¬?? Engineering Industry.
The investments made between 1966-1970 were mainly directed towards the development of hot sector, especially the centrifugal casting, the metallic structures???¬?? construction and the technological equipment manufacturing.
1970-1980 is the period for the factory to profit of another 2 development stages, having as results the extension of the existing manufacturing capacities, increase of the integration
degree, new products of high technology being inserted. It is the period for the factory to be considered as ???¬?The Chief Engineer ???¬? of the Romanian Metalworking and Iron and Steel Industry. In December 2006, S.C. Metalurgica Aiud sold its assets and commercial fund to S.C. Remarul 16 Februarie S.A. CLUJ NAPOCA, company with 100% private capital.
So it was founded REMARUL METALURGICA AIUD as Work point of S.C. Remarul 16 Februarie S.A. CLUJ NAPOCA.
In 2008 REMARUL METALURGICA AIUD changed the name in METALURGICA TRANSILVANA AIUD.
Metalurgica Transilvana Aiud is an integrated company, having at its disposal primary sectors that ensure static and centrifugal casting, forging, heat treatment, mechanic and welded assembling and machining sectors.

In this plant are developed two different groups of technological processes: forging and primary and secondary heat treatments. There are forged ingots in the range between 3 to 16 tons, cast in the Steel Foundry nr. 2, as well as wrought milled steel products supplied by others. Forged pieces are submitted to primary heat treatments. The main types of forged and heat ???¬?? treated pieces are:
???¬?? Milling rolls.
???¬?? Perforating and milling spikes.
???¬?? Spike heads for the 20???¬?????¬?? Pilger rolling mill.

All these are manufactured in a wide range of steel grades, from carbon, low, medium alloyed, to stainless and refractory steel grades. We shall specially mention the hyper-eutectic steel for hot or cold milling rolls, those for tubing milling rolls, alloyed with Cr, Ni, Mo, V, W.
In order to forge spare parts from rolled steel, there is a various range of free forging hammers, like: 80 kg, 160 kg, 200 kg, 400 kg, 2 tons and 5 tons. But the basic equipment is the 3150 tons hydraulic press, where the ingots are processed on, enabling drawing operations from ingots up to 30 tons, and upsetting operations from ingots up to 18 tons. The press is endowed with forging devices suspended in 80 tons gantry cranes. The ingots???¬?? heating is carried out in hearth furnaces for hammer forging, and in roller heart furnaces, with the hearth surface of 16 m2 and 25 m2, for hydraulic press forging.
In the forging sector, there are also furnaces for primary heat treatments, all with roller hearth, with the hearth???¬??s surface of: 6,3 m2, 16 m2, 25 m2 and 32 m2, enabling normalising, annealing, dehydrogenation treatments.
Secondary heat treatments:
It may be treated any range of parts, respecting the size limitations of the treated spare parts:
???¬?? maximum lengths (for shaft type parts) ???¬?? 8 m
???¬?? maximum diameter (for wheels, bandages, a.s.o.) ???¬?? 3,5 m
???¬?? maximum weight ???¬?? 24 tons.
Here can be performed operations like: quenching ???¬?? tempering, austenitizing,
case hardening, and superficial quenching with high frequency currents, ionic nitriding heat treatments.
For quenching ???¬?? tempering treatments, there are roller hearth furnaces with the hearth surface of 4 m2, 6,3 m2, 16 m2 and 25 m2, with water or oil horizontal quenching tanks, as well as batteries for the heat-treatment of the shaft type parts up to 8 m long, consisting of: vertical furnaces, vertical tanks for oil hardening, rinsing tanks, vertical tanks for water quenching and water-cooler tower.
???¬?? The case hardening is carried-out in an electric furnaces with methane gas atmosphere, with 1420 mm nominal diameter and nominal height 3050 mm.
???¬?? For the superficial quenching, there is an equipment with 2 working stations:
- the working station for gear wheels???¬?? hardening, with the diameters???¬?? range between 500 ???¬?? 4000 mm, for straight teething, with the range of modules between 7-40, or for bent teething, with the range of modules between 7-20, maximum weight 2000 kg.
- the working station for shafts with a maximum diameter of 200 mm, with a 4000 mm quenching area and 5000 mm grip length.
For the ionic nitriding there is a separate shop, with proper microclimate. The equipment is made in Romania, INI 150 type and it is endowed with 2 tanks with the dimensions of ????800 x 4000 mm length and ????1500 x 2000 mm length, which allow the treatment of charges with maximum dimensions ????650 x 3300 mm and ????1300 x 1400 mm, with weights up to 3000 kg.

In order to determine the hardness in inaccessible places, there is mobile ECOTIP equipment, which determines the hardness in its own LD units and convert them into all the other systems.
???¬?? The metallographic analysis laboratory, where are carried out:
- macroscopic analysis, for as-cast, forged, rolled or draw products.
- microscopic analysis with NEOPHOT 2; MC2; MC 6 type microscopes.
- micro-hardness.
- photographs of the macrostructure and microstructure.
- determination of the metals???¬?? corrosion.
- determination of the ferrite???¬??s content in the alloyed steel grades.
- heat treatments.
???¬?? Gas content in steel analysis laboratory :
- nitrogen and oxygen with LECO RH2 AND LECOTC 36 Analyser.
???¬?? Toxicological and Environment Analysis Laboratory, where are achieved:
???¬?? solid particles and CO2 content determination, environmental determinations (rain water and atmospheric particle sediments???¬?? analysis).
???¬?? Water and oxygen analysis laboratory.
???¬?? The moulding material analysis laboratory.
THE QUALITY INSPECTION is a department that has a great importance for METALURGICA TRANSILVANA AIUD. In this department, with the existing endowment and authorised personnel, can be carried out:
Ultrasonic inspections ???¬?? with KRAUTKRAMER USM 25S equipment. Magnetic particle inspections ???¬?? with magnetic yoke ???¬?? PARKER B 300 B 300 S equipment.
Die penetrant examinations.
Penetrant radiation inspection (X-ray), for thickness???¬?? up to 35 mm with ANDREX 3001; MXR 301 type equipment.
Magnetic particle examinations ???¬?? with magnetic yoke ???¬?? type Parker B 300
Hardness determination ???¬?? with mobile EQUOTIP, SONODUR and POLDY type equipment.
Roughness determination ???¬?? with movable HOMMEL TESTER T 500 type equipment.
