Steel Ladle Refining Furnace

Steel Ladle Refining Furnace - Premium Secondary Metallurgy Solution

Shaanxi Heyuan's Steel Ladle Refining Furnace delivers exceptional secondary refining capabilities for modern steel production facilities. Our advanced system operates at 1550°C-1700°C with precise ±3°C temperature control, handling ladle capacities from 10t to 150t. With transformer capacity ranging from 10MVA to 100MVA, our furnace achieves inclusion content ≤10μm and composition deviation ≤±0.03%. Backed by over 20 years of metallurgical expertise and 400+ global installations, we provide complete turnkey solutions with annual operating time ≥8500 hours.

What Makes Our Ladle Refining System Special?

Your steel production demands precision and reliability. Our refining furnace bridges the gap between primary melting and continuous casting, solving critical industry challenges.

The system eliminates thermal stratification that causes nozzle clogging during casting. It removes sulfur and oxygen to meet high-grade steel specifications. Most importantly, it acts as a logistical buffer synchronizing melting furnaces with casting sequences.

Core Refining Functions

Our product integrates multiple refining processes in one unit. Electric arc heating provides precise temperature control. Argon stirring ensures uniform composition throughout the ladle. Slag washing refining effectively removes sulfur, phosphorus, and non-metallic inclusions.

These combined functions significantly improve molten steel cleanliness. You get consistent quality that meets high-grade steel production requirements.

Technical Specifications

Key Applications Across Industries

API Grade Line Pipe Steel Production: Our system excels in deep desulfurization and inclusion shape control. This prevents Hydrogen Induced Cracking and Sulfide Stress Cracking in oil and gas transport pipes.

Bearing & Gear Steel Manufacturing: Extended soft stirring periods float out oxide inclusions. This ensures high fatigue life for automotive transmission gears and industrial bearings.

Stainless Steel Refining: Precise ferroalloy addition under tight temperature control. Achieve correct phase balance and corrosion resistance for chemical processing equipment.

Advanced System Features

Precise Temperature Management

Your production schedule requires consistent heating rates. Our three-phase AC arc system delivers 3°C to 5°C per minute heating using 300mm-600mm diameter graphite electrodes.

Superior Stirring Technology

The argon stirring system uses flow closed-loop control for uniform mixing. This eliminates hot spots and ensures consistent composition throughout the ladle.

Quick Response Electrode System

Hydraulic response times under 100ms provide instant arc length adjustment. This maintains stable heating and prevents electrode breakage.

Efficient Furnace Design

The hydraulic lifting furnace cover opens and closes easily. High operation efficiency maximizes your production uptime.

Quality Control Excellence

We implement rigorous inspection procedures for every Steel Ladle Refining Furnace delivery. Our electrode regulation system undergoes hydraulic response testing. Water-cooled roof sections receive mandatory pressure testing to prevent dangerous leaks.

Process quality control includes Optical Emission Spectroscopy data verification. Hydrogen monitoring ensures safe operation. Argon stirring system integrity checks guarantee consistent performance.

Refractory wear monitoring via laser profiling assesses slag line condition. This proactive approach prevents unexpected downtime.
