EAF-EBT Forni ad arco - Progettati per l’eccellenza

forni ad arco

AC arc furnace
The oven offered is the most advanced solution in terms of resistance simplicity and reliability. Result of continuous development, this oven optimizes the power on-time timing, the high-speed movement and high accessibility to all the components for maintenance. This oven is ideal for a high energy input, and an overall increase in performance can be achieved with the latest technologies to supply oxygen and
coal. We offer a wide range of optimal solutions for the merger. Our furnaces include UHP EAF for a 'of the basin filling operation, single or multiple and twin-shell furnaces. The furnace EAF iè the ideal melting tool for the production of all types of steel, from standard up to steel alloy and stainless steel.


Features

  • Gantry design for self-supporting once
  • Roller-driving system for prismatic electrodes
  • electrically conductive arms in two-component copper-steel sheet
  • advanced control system
  • Semitino spilled-shell
  • copper panels or combined high speed of movement
  • methane oxygen burners
  • Coal and oxygen injectors
  • All tapping from the bottom systems (EBT, EO-EBT, RBT, OBT, FAST)
  • hot charging capacity
  • Continuous feeding DRI / HBI (DRI purposes and dust injection)


Key benefits

  • Increased productivity due to the reduced melting time and downtime

  • High impedance up to 1,350 V
  • Low levels of consumption (energy, electrodes, refractory, etc.)
  • Low temperature tapping and dragging minimum slag)
  • Reduced maintenance thanks to the use of robust components and high flexibility with respect to the fillers)

LF Forno siviera - Progetto per i più alti standard

forno siviera

The installation of the ladle furnace between the melting area and the casting area is vital to ensure quality increments and / or productivity in the steelworks. The type of ladle furnaces can be single station, (with fixed or rotating or ladle / turret) wagon portal or with twice enslaved to a gate electrode rotating portal.

Features
The most advanced and performance design features:

  • Once cooled with central refractory lining
  • Automatic lance for the outlet temperature of samples
  • automatic manipulator for mixing and / or the injection of powder
  • Power with cored wire for the deoxygenation and microlegaggio
  • automatic connection system for mixing gas
  • Easy access at a time and easily replaceable electrodes
  • inert gas system for remixing (porous plug and / or spear)

main goals

  • Reduction of the "bottleneck" between melting and casting
  • Optimization of the times and temperatures of refining the tapping
  • Precise temperature control for continuous casting
  • Cleaning and homogenization Steel
  • Realization of the desired composition of the steel (fine metallurgical adjustment)

main benefits

  • Substantial improvement in the quality of the steels
  • Substantial reduction in the refractory consumption
  • Substantial improvement in the casting yield
  • Substantial reduction of total costs

Metallurgia secondaria - progetto per la qualità

A competitive production and quality is unthinkable today without secondary metallurgy solutions. The technologies are provided that all the most advanced technological solutions in this field to provide manufacturers with the tools for the production of a higher quality steel. Today over 170 of secondary metallurgy operations are operating based on this system and are provided in the world with a capacity of the ladle from 5 to 300 tons.

Ladle Treatment Stations
Positioned between the melting zone and the continuous casting, the treatment station in the ladle is the minimum investment required for the secondary metallurgy treatments.

You realize the following functions:

  • Homogenisation of temperatures by applying porous plug or launches agitator
  • Alloy Setting
  • Adjusting the temperature of steel
  • Deoxidation with aluminum or additives
  • Desulphurization with synthetic slag or powder injection

Degasser vacuum
metallurgical operations quail degassing, deoxidation, decarburization, desulfurization, as well as the allegaggio are conducted in a vacuum plant. According to the specific demands of each manufacturer they can be provided, different types of the degassing system.

Vacuum circulation process
In the vacuum circulation systems, for example (VCP VCP-O), all metallurgical treatments are made rapidly in a separate ladle, coated with refractory, equipped with two plunger immersed in the steel bath. By reducing the system pressure and injecting inert gas into the upper plunger, the liquid rises inside the vacuum container where the decarburization and other reactions occur. The steel then recirculates to the inverse in the ladle, through the lower plunger. In this way, the entire casting can be treated quickly and the free edge in the ladle required can only be of 200 cm.

main benefits

  • Reactions accelerated in a vacuum
  • Achievement of low contents of C, H2 and N2
  • insufflation of oxygen option with the VCP-O process for a forced decarburization.
  • Argon injection for better decarburization
  • Post combustion with accumulation patented system based on the injection of air inside the CO gas output
  • Patented seal against leakage
  • improving steel cleanliness general
  • Refinement of exact analytical values ​​with low investment and operating costs
  • Reactions accelerated in a vacuum
  • Achieving low contents of C, H2 and N2
