Tundish Preheating System

Tundish Preheaters can be used for drying and heating of Tundish. We design preheaters from Bloom, Slab, and Billet Casters for open or close casting applications.

The different types of requirements are:-

1. Tundish Dryers: These are required to remove the moisture from green or newly lined Tundish. These generally have a very slow heating rate and a long process duration which ensures that the refractory is subjected to as minimum of thermal shocks as possible. The burners for these burners are specially designed to produce a short and lazy flame.

2. Tundish Preheaters: These are used to heat the ladle at a faster heating rate before taping of the ladle, the burners for these types of preheaters have a short and very intense flame, ensuring a high heat transfer from the flame to the refractory lining, ensuring that the ladle is fully soaked.

We are offering the following additional enhancement:-

1. Recuperative Type Preheater: Flue gases exhaust from the ladle at a very high temperature ( 1000 C and above), We use the heat from flue gasses to preheat the air by using a customized heat exchanger specially designed for Ladle applications and are able to save up to 25% in the running cost.

2. Oxy Enrichment: Oxy enrichment is used either to achieve a higher heating temperature of more than 1200 C or to reduce fuel consumption or reduce the cycle time. The energy-saving can vary from 10 to 25% depending upon the level of enrichment.

3. Multi Fuel Fired: All the burners are custom designed and are for specific requirements and as such, we can use multiple types of fuel in the same burner (liquid/Gaseous) without changing the burner, we also supply burners that can fire multiple gaseous.

4. Special hood for close casting

These systems can be energized by almost all Liquid and Gaseous fuel. We are supplying systems that are using blast furnace gas (800 Kcal/Nm3)

We can offer various types of hood movement for the systems:-
