Compact, Flexible, and High-Efficiency Casting Solutions for Modern Steel Plants
Introduction
With the continuous development of steelmaking technology, steel producers are increasingly seeking compact, energy-efficient, and cost-effective continuous casting solutions. Compared with traditional ingot casting, billet continuous casting production lines significantly improve productivity, reduce energy consumption, and ensure consistent billet quality.
Small-radius steel billet continuous casting machines have become an ideal choice for mini steel mills, rolling plants, and integrated casting-rolling lines, especially where workshop space, investment budget, and operating manpower are limited.
Product Overview: Steel Billet Continuous Casting Production Line
Our steel billet continuous casting production line is available in multiple radius configurations, including R2.5M, R3.5M, R5.25M, R6M, and R8M, ensuring optimal adaptation to different billet sizes and production capacities.
The equipment is designed with matching casting radius, which effectively reduces internal stress during solidification and bending, improves billet surface quality, and ensures stable long-term operation.
Billet Size & Casting Configuration
The production line supports a wide range of square billet sizes, including:
- 60mm × 60mm
- 70mm × 70mm
- 80mm × 80mm
- 90mm × 90mm
- 100mm × 100mm
- 120mm × 120mm
- 180mm × 180mm
- 220mm × 220mm
Both single-strand and multi-strand casting configurations are available, allowing customers to flexibly match their production requirements and future expansion plans.

Main Equipment Composition
The steel billet continuous casting production line consists of the following key components:
- Main steel ladle
- Tundish (middle steel ladle)
- Copper crystallizer
- Mold vibration device
- Arc section
- Primary water cooling system
- Secondary water cooling system
- Dummy bar system
- Billet pulling device
- Multi-point straightening unit
- Automatic cutting device
Each component is carefully designed and matched to ensure smooth molten steel flow, uniform solidification, and stable billet withdrawal.
All-in-Type Continuous Casting Machines
R2.5M All-in-Type Continuous Casting Machine
The R2.5M model is an ultra-compact, all-in-type continuous casting machine designed for small-scale steel production.
- Billet sizes: 60mm, 70mm, 80mm
- Extremely small footprint
- Low investment and fast installation
- Ideal for startup steel plants or limited workshop spaces
R3.5M All-in-Type Continuous Casting Machine
The R3.5M model offers greater flexibility and capacity while maintaining a compact structure.
- Billet sizes: 70mm, 80mm, 90mm, 100mm, 120mm
- Widely used in continuous casting & rolling production lines
- Balanced solution for medium-capacity steel plants
Both models adopt an all-in-type integrated structure, significantly shortening installation and commissioning time.
Key Technical Features and Advantages
Compact Layout and Space-Saving Design
- Small occupation area
- Flexible worktable size depending on installation method
- Suitable for workshops with limited space
Flexible Casting Methods
The production line supports various molten steel casting methods, including:
- Crane ladle casting
- Rail car ladle casting
- Electric furnace direct casting
This flexibility allows easy integration with existing steelmaking processes.
Low Workshop Height Requirement
Small continuous casting machines have low requirements for workshop height.
If the available height is insufficient, the foundation can be excavated by approximately 1 meter, significantly reducing civil construction costs.
Fast Installation and Commissioning
Thanks to the all-in-type structure, the machine can be installed directly by crane.
Once water and electricity are connected, the production line can be put into operation, enabling rapid project startup.
Continuous Casting & Rolling Integration
The steel billet continuous casting line can be directly matched with 25-type or 30-type rolling mills.
Only 300°C billet reheating is required before rolling, enabling:
- Energy savings
- Shorter production cycles
- Higher overall production efficiency
This configuration is especially suitable for continuous casting and rolling integrated production lines.
Low Operation Threshold and Easy Training
- Low molten steel pouring weight requirement, ranging from 100 kg to several tons per heat
- From startup to pouring can be completed within 10 minutes
- Operators can become skilled after short-term training
- Reduced dependence on highly experienced technical personnel
These features make the production line ideal for plants with limited manpower or new operational teams.
Cooling Water and Material Adaptability
Low Cooling Water Requirements
- No strict requirements on water quality
- No limitations on acidity, hardness, or mineral content
- Any locally available water source can be used
Wide Steel Grade Applicability
The continuous casting line is suitable for producing billets from:
- Low carbon steel
- Medium carbon steel
- High carbon steel
- Alloy steel
- Stainless steel
This wide adaptability enables flexible production planning.
Reliable Operation and Easy Maintenance
- Simple and intuitive operation
- Adjustable casting speed
- Stable and reliable long-term running
- Simplified mechanical structure
- Reduced maintenance workload and operating costs
The design philosophy focuses on reliability first, ensuring continuous and stable production.
Typical Applications
- Mini steel mills
- Small and medium-sized rolling plants
- Continuous casting & rolling production lines
- Steel plants upgrading from ingot casting to continuous casting
