BOF & EAF Refractories
GUOLIANG supplies high-performance BOF & EAF Refractories for demanding primary steelmaking applications. Our refractory products are designed to withstand high operating temperatures, aggressive slag attack, molten steel erosion, thermal cycling and mechanical stress in Basic Oxygen Furnaces and Electric Arc Furnaces.
Our current product range includes BOF Sliding Gate Plates for converter tapping and slag control, as well as Refractory Precast Blocks for BOF and EAF furnace applications.
According to furnace design, steel grade, slag chemistry and operating conditions, GUOLIANG can provide customized refractory materials, shapes and technical recommendations for steel plants.
A Basic Oxygen Furnace operates under severe thermal, chemical and mechanical conditions. Refractory materials must tolerate repeated steelmaking cycles, high-temperature molten steel, oxidizing slag, rapid temperature changes and localized wear.
GUOLIANG BOF Refractories are designed for converter steelmaking applications where reliable slag resistance, erosion resistance and thermal stability are required.
Our BOF refractory solutions can be used for applications such as:
The BOF Sliding Gate Plate is used in the converter taphole sliding gate system to control molten steel discharge during tapping and help reduce unwanted slag carryover into the steel ladle.
It requires high thermal shock resistance, erosion resistance, mechanical strength and stable sealing performance.
Electric Arc Furnaces expose refractory linings and components to intense arc radiation, high temperatures, slag attack, thermal cycling and mechanical wear during scrap or other metallic charge melting.
GUOLIANG EAF Refractories are developed for applications requiring high-temperature stability, thermal shock resistance, corrosion resistance and mechanical strength.
Refractory selection should consider:
GUOLIANG Refractory Precast Blocks are prefabricated refractory shapes designed for steelmaking furnace applications.
Compared with conventional on-site refractory construction, precast components provide controlled factory manufacturing, accurate dimensions and convenient installation.
Our precast blocks provide:
They can be manufactured according to customer drawings and specific furnace installation positions.
Although BOF and EAF are both primary steelmaking furnaces, their operating conditions and refractory wear mechanisms differ.
| Factor | BOF | EAF |
|---|---|---|
| Furnace Type | Basic Oxygen Furnace | Electric Arc Furnace |
| Heat Source | Oxygen refining reaction | Electric arc |
| Main Refractory Challenges | Slag corrosion, oxidation, tapping wear, thermal cycling | Arc radiation, slag corrosion, mechanical wear, thermal cycling |
| Important Areas | Working lining, taphole, slag zones, bottom | Sidewall, slag line, taphole, bottom, roof areas |
| Refractory Selection | Based on converter zone and steelmaking conditions | Based on furnace zone and melting practice |
For this reason, refractory products should be selected according to the actual furnace zone and operating conditions rather than using one refractory grade throughout the entire furnace.
Steelmaking slags can aggressively attack refractory linings. The refractory composition should be compatible with the slag chemistry and furnace operating conditions.
Refractories must maintain structural stability under high-temperature steelmaking conditions.
Repeated heating, cooling and temperature fluctuations can cause cracking and spalling. Good thermal shock performance is therefore important for furnace reliability.
Molten steel flow, slag movement and mechanical action can accelerate refractory wear in critical furnace areas.
Consistent raw materials, manufacturing processes and quality control help provide predictable refractory performance during steelmaking operations.
BOF Refractories are selected primarily for converter steelmaking conditions, where oxidizing slag, oxygen blowing, tapping and repeated converter cycles create demanding refractory wear.
EAF Refractories operate under electric arc heating, intensive thermal loads, slag attack and mechanical stress associated with melting operations.
Although some refractory material systems may be used in both furnace types, the grade, composition and structure should be selected according to the specific operating zone.
GUOLIANG evaluates actual steelmaking conditions before recommending refractory materials.
When requesting a refractory solution, steel plants should provide as much operating information as possible.
Important parameters include:
This information helps determine the appropriate refractory composition, product structure and installation solution.
Different steel plants operate with different furnace designs and steelmaking practices.
GUOLIANG can provide customized refractory products according to customer requirements, including:
For refractory replacement projects, customers can provide current product drawings, specifications, service life data and failure observations for evaluation.
GUOLIANG provides refractory materials and functional refractory products for iron and steel production.
Our product portfolio covers multiple stages of metallurgical production, including:
This enables steel plants to source compatible refractory materials across different stages of the steelmaking and continuous casting process.
BOF refractory selection varies according to furnace zone and operating conditions. Working linings, tapping areas and other high-wear zones require refractory materials with appropriate slag, erosion and thermal resistance.
EAF refractory systems commonly require materials capable of resisting high temperatures, arc radiation, slag corrosion, thermal cycling and mechanical wear.
Not necessarily. Although some refractory material systems can be used in both applications, different furnace conditions and wear mechanisms require specific material and product selection.
