The Upgrade of Kerui High-grade Refractories Plant

Intelligent Batching System

33-can Fully Automatic Premix System: Ensure precise batching of corundum, zircon, chrome corundum and other high-grade materials.

Pipeline Conveying With Screw Metering: Lower material contamination below 0.02%.

Dynamic Formula Adjustment: Cut special-order response time by 50%.

Advanced Molding Process

5 Heavy Press Clusters (630T-1200T): Handle all product types from insulation bricks to chrome corundum bricks.

Double-impact Pressing: First impact removes air (increases closed-cell rate by 18%); Second impact compacts material (increases bulk density by 18%).

Adaptive Impact System: Automatically adjusts pressing settings for zircon mullite, sillimanite and other materials.

High-Temperature Firing System

New 118-meter 1700°C Tunnel Kiln: Reduce firing cycles for high-grade bricks.

Dual Shuttle Kilns: Support small-batch custom orders like premium silicon carbide castables.

Smart Temperature Control: Maintain ±5°C precision during crystal phase changes.

Digital Castable Production

Smart Castable Production Line: Enable flexible production switching between corundum, chrome corundum and silicon carbide castable.

Real-time Quality Monitoring: Check flowability and setting time during production. Increase product qualification rate to 99.6%.
