What is SURCAST QuickStart?
- Traditionally, preparing a Tundish backup lining typically takes about a week. Once cast, the lining requires approximately 24 hours for air curing.
- Subsequently, it undergoes a heating process with variable rates, starting from 20-30°C per hour until reaching the terminal temperature.
- SURCAST QuickStart is a specialized castable Tundish safety lining developed by Vesuvius for a rapid heating cycle known as the ‘QuickStart’ heating cycle.
- The Tundish with a SURCAST QuickStart lining can be heated at a rate of 50°C/h till 540°C and then at 100°C/h until the highest temperature, depending on equipment availability.
- This lining can be ready within ~25h and can, therefore, undergo severe thermal curing cycles.
Customer requirements:
- Reduced Tundish Shell Temperature
- Homogenised steel temperature
- Increased steel volume in tundish
- Stabilised thermal cycling
Vesuvius recommendation:
Introducing our premium SURCAST QuickStart –
Energy Efficient Tundish Safety Lining designed to reduce
the amount of material Energy wasted during processing.
SURCAST QuickStart castable key features:
- A 25% reduced thermal conductivity
- Vesuvius rapid drying and QuickStart technology
- Excellent safety slag-line erosion and corrosion resistance
Total cycle time
Thermal Conductivity - Maintain the SUPERHEAT in Tundish
The lining made with Surcast QuickStart is designed to reduce the shell temperature drop.
The tundish preheating time can be reduced as the heat is contained ‘within.’
The maintain of superheat in tundish reduces the risk of steel freezing conditions.
Application: tundish safety lining
- Can be used as a vibratable concrete (5.5 – 6.0% water) or as a self-flow (6.0-6.5 % water).
- Can be used with current insulation bricks/panels to improve insulation i.e. better maintain tundish steel temperatures / potentially lower ladle superheat temps, main recommendation…or,
- Used with no / less insulation to maintain current tundish temps / superheat temps and save on material insulation costs and time.
