Product Description

 

Product Description

The ladle preheater (ladle baking system) is a critical thermal equipment in metallurgical industries designed to preheat ladles (steel molten metal containers). Its primary function is to elevate the ladle lining temperature to an optimal range before filling with high-temperature molten steel, thereby minimizing steel temperature drop, extending refractory lining service life, and enhancing process stability and energy efficiency

Feature of Ladle Preheater

Regenerative Combustion Technology

*Paired regenerators alternately absorb and release heat, preheating air/fuel to above 800°C, achieving 80% thermal efficiency and reducing fuel consumption by 40-50%.

*Dual Regenerative Mode: Preheats both air and fuel, ideal for low-calorific-value gases (e.g., blast furnace gas).

Intelligent Temperature Control

*Employs PID algorithms or AI models to dynamically optimize combustion parameters, ensuring ladle lining temperature uniformity (ΔT ≤ 50°C) and extending refractory life by 20-30%.

Multi-Fuel Compatibility

*Supports natural gas (NG), liquefied petroleum gas (LPG), blast furnace gas (BFG), etc., with valve assemblies enabling seamless fuel switching.

High-Velocity Burner Optimization

*Flame jet velocity reaches 200-300 m/s, enhancing convective heat transfer and shortening preheating time (e.g., heating a 30-ton ladle from ambient to 1000°C in 1.5 hours).

Classification

By Fuel Type *Natural gas preheaters, blast furnace gas preheaters, coke oven gas preheaters, etc. By Operation Mode *Online Preheaters: Integrated directly into production lines for zero-wait ladle turnover. *Offline Preheaters: Used for ladle maintenance or standby preheating, offering operational flexibility. By Structural Design *Vertical Preheaters: Suitable for space-constrained workshops. *Horizontal Preheaters: Deliver superior heating uniformity for large ladles (≥200 tons).

Application

Electric Arc Furnaces (EAF) and Basic Oxygen Furnaces (BOF) *Preheat ladles to 800-1200°C before steel tapping, reducing molten steel temperature loss by 30-50°C. Ladle Refining Furnaces (LF/VOD) *Preheat ladles to 1000-1250°C prior to refining, ensuring efficient metallurgical reactions. Continuous Casting Tundish Preheating *Heat tundishes above 1100°C to guarantee successful casting initiation. Ferroalloy Smelting *Corrosion-resistant preheating for ladles handling high-temperature melts (e.g., ferromanganese, ferrochrome).
