Electric Arc Furnace
In our Melt Shop, the first stage of production starts with Electric Arc Furnace equipped with bottom casting (EBT) system. Carbon, oxygen and temperature determination of liquid steel is made with special measuring equipment. All production processes in the arc furnace are controlled by computer and PLC system.

The electric arc furnace having 25 MVA Transformer power has 30 tons liquid steel capacity. The benefit of the EBT system is that the arc furnace slag is not carried into the ladle during tapping. With the investments made in 2013 and 2015, the electric arc furnace has been modernized, the volume of it has been increased, the dust collection system has been improved and a new combustion chamber has been made to protect the environment

Ladle Furnace
While the liquid steel in the ladle furnaces is automatically alloyed with the automatic alloying system according to the target chemical analysis of the steel quality to be produced, gas is blown into the ladle from the bottom to ensure that the steel temperature and chemical composition are homogeneous. In the ladle furnace, the temperature of the liquid steel, oxygen and hydrogen levels, and the slag analysis are determined using modern measuring devices.

Vacuum Degassing
This stage has a very important role in the production of special steel. The oxygen, hydrogen and nitrogen gases dissolved in the liquid steel cause many harmful effects. Vacuum degassing processing aims to remove these gasses which are dissolved in liquid steel, with argon gas stirring under vacuum.

Wire Injection Systems
Aluminum, Calcium, Sulfur, Carbon, Titanium, Boron wires are injected to the liquid steel to reach the target chemical composition of the grade.The amount of wire is determined by the chemical composition of the grade. Wire injection systems are fully automatic and PLC controlled

Continuous Casting Machine
After finishing of all operations, the liquid steel is sent to Continuous Casting Machine.In Continuous Casting Machine. With this machine,140,160 and 200 mm billets are produced.

With closed casting system, liquid Steel doesn’t get in touch with air and this prevents re-oxidation. The Continues Casting Machine is equipped with a multi-stage cooling system which has a direct impact on the product Quality and level1 and level2 control systems are used to monitor all stages of the production. It has a very important place in the production of Quality steel and is used with the know-how unique to Çemtaş.

In the continuous casting machine, temperature, oxygen and hydrogen levels of the liquid steel are measured using modern measuring devices. After solidification, the billets are cut to the desired lengths with oxy-fuel billet cutting system and are labelled with the billet labelling unit located in the cooling grid in order to ensure traceability of the cast.
