Ladle treatment method for cast iron – Cored wire treatment method

During the 1980s the steel plants’ production needed the integration of elements such as additives and inoculants to improve the metal treatment process.

After a little while iron foundries themselves, producing nodular iron castings, identified the same necessity for ladle treatment of cast iron.

The state of the art regarding the ladle treatment methods though has developed over the years from the Sandwich ladle treatment method to the Tundish ladle treatment method and finally to the Cored wire treatment method.

How do these methods differ and why does our company supplies systems that applies the Cored wire treatment method?

Thermal analysis of cast iron – TCAST

Each iron foundry distinguishes itself for its own casting production, using its own peculiar alloys’ composition. Such alloys’ composition can vary depending on the material and the specific requirements of the clientele.

Moreover, depending on how the metal is metallurgically treated, the same properties of the cast iron can vary significantly.

Given such particular needs, it becomes most of the times necessary to analyze the fundamental characteristics of the cast iron such as the macro and micro structure and the mechanical properties.

Such characteristics can be studied by determining the heat flow, the chemical composition, the microalloyed and the impurities, the metallurgical processes carried close to the furnace or directly in ladle and finally the inoculation methods currently in use in the foundry.

Taken into consideration such contingencies, our company has decided to develop TCAST, a dedicated software for thermal analysis of cast iron.

Planning and realization of ladles

In view of demanding clientele in this sector, DUEDI has realized a building system of ladles totally removable.

The main advantages of this newest type of ladle are multiple, especially in the maintenance and the security sectors.

In particular in the maintenance area:

  1. All parts of ladle are totally removable
  2. Shorter maintenance time is needed because all parts are bolted
  3. Many parts can be re-used
  4. The total maintenance can be realized by all customers autonomously
  5. The driving trunnion and the idler trunnion can be removed from the body of ladle
  6. Simple maintenance for all customers

 

And  in the security area:

  1. Worm-screw and gear wheel are always fixed
  2. Highest safety is guaranteed for all users during the various operating phases
  3. Highest productivity, flexibility, reliable and accurate pouring mode are guaranteed by wireless radio control
  4. In case of power failures of the gearmotor, it’s easily possible to switch from automatic to manual mode (steerling wheel) in maximum 10 seconds

 

Every ladle’s sizes are always adaptable to the factory customer layout and for every ladle we can supply the all certifications (mechanical certification, capacity certification, welding certification and  CE certification).


Hydraulic foundry wedge

Fassmet has designed a robust and reliable breaker machine that is also very easy to handle. Used to break feeders and ingate systems DUEDI’s SFW hydraulic breaker consists of a wedge which is moved by a hydraulic power pack.

The main advantages of this product are:

  • ERGONOMIC and USER-FRIENDLY: it rotates in every direction without any strain on the operator due to position of center of gravity;
  • QUICK and EASY TO USE: this specific wedge is durable and can be replaced very quickly. No tools are needed;
  • POWER: it can remove almost any feeder or ingate system and provides high productivity (high number of spreading cycles per minute). Attributes such as a full protection cover and the fact that the tools supports two-handed operation, greatly limit the chances of accidents happening. Another feature is that the tool provides clean predictable cuts, guaranteeing that feeders and risers break off in a controlled manner;
  • SAFETY: it attributes such as a full protection cover and the fact that the tools supports two-handed operation, greatly limit the chances of accidents happening. Another feature is that the tool provides clean predictable cuts, guaranteeing that feeders and risers break off in a controlled manner;
  • QUALITY AND RELIABILITY: made of high quality materials (DUEDI’s product) and is designed for durability and long operational and working life;
  • FLEXIBILITY: it can be used in different kinds of processes. Thanks to the shape of the front protections the slides can be used for all their length, greatly increasing the work area;
  • MANAGEABILITY: this machine is designed for heavy duty and the joystick gives perfect control of its movements. The design of the handle has a symmetric design and allows left-handed operators easily work with ease;
  • DURABILITY: our machine is designed to last and are more durable compared to traditional breakers;
  • SAFETY: equipped with a full protection cover which minimizes risk for operators.
