Kerui Refractory recently completed the shipment of magnesia carbon bricks and ladle lining materials to a steel plant in Uzbekistan. These ladle refractory bricks will be used in the customer’s steel ladle system to improve lining stability under high-temperature steelmaking conditions.
Customer Requirements and Existing Problems
At the beginning of the project, the customer provided their current refractory specifications, operating temperature range, and ladle working conditions.
During previous use, the customer experienced several common problems with their existing ladle bricks:
- Severe wear in the slag line area
- Short service life of magnesia carbon bricks
- Cracking in high-temperature zones
- Frequent maintenance and relining work
These issues affected production efficiency and increased refractory consumption costs.
Technical Communication and Material Adjustment
After reviewing the operating conditions, Kerui technical team carried out several rounds of technical communication with the customer to discuss the performance of the existing ladle refractory bricks.
Both sides mainly focused on:
- Slag corrosion resistance of magnesia carbon bricks
- Thermal shock resistance under repeated heating cycles
- Different material requirements for slag line and working lining areas
- Service life expectations for the ladle lining system
Based on the discussion results, Kerui Refractory recommended upgrading the original slag line bricks to higher-performance MgO-C bricks with improved corrosion resistance and structural stability.
After confirming the revised material configuration and technical details, both parties finalized the order.
Production and Shipment
Kerui Refractory arranged production of the magnesia carbon bricks according to the confirmed specifications. After quality inspection and packaging, the materials were shipped to the Uzbekistan steel plant on schedule.
The shipment included:
- Magnesia carbon bricks for slag line areas
- High-strength ladle bricks for working lining zones
- Supporting refractory materials for ladle maintenance
The materials will be installed during the customer’s scheduled maintenance period.
Customer Feedback and Ongoing Support
According to current feedback from the customer, the magnesia carbon bricks are performing well under actual operating conditions. The ladle lining system remains stable, and the wear condition has improved compared with the previous materials.
Kerui Refractory will continue to follow up on the service performance and provide ongoing technical support for future ladle maintenance work.
If you are also facing problems such as slag line erosion, short ladle lining life, or unstable ladle refractory brick performance, feel free to contact Kerui Refractory for suitable refractory material recommendations and technical support.
