Composition and Manufacturing

Gotrays Chrome Corundum Castable is carefully formulated for top performance in tough furnace environments. It’s made from a precise mix of high-quality aggregates, fine powders, binders, and special additives to create a dense, durable lining.

Our unique manufacturing process uses high-temperature fusion to create a solid solution phase in the castable. This means the material achieves uniform density throughout with zero impurities, ensuring consistent strength and reliability. This fusion step also enhances the chrome oxide corundum aggregate’s natural erosion and corrosion resistance, giving you a lining that lasts longer under harsh conditions.

This careful blend and advanced process make Gotrays castable stand out as a high alumina chrome corundum mix that’s built for the demands of industries like steel, petrochemical, and power generation across the U.S.

Applications and Case Studies

Gotrays Chrome Corundum Castable is built to handle tough conditions across multiple industries. Here’s where it shines:

• Petrochemical: Perfect for reactors and high-temp chambers exposed to corrosive gases and slag.
• Metallurgy: Delivers long-lasting protection for furnaces, reducing downtime and maintenance costs.
• Waste Management: Withstands aggressive environments in waste incinerators and gasifiers.
• Glass: Improves furnace lining life, resisting erosion from molten glass and chemicals.
• Power Generation: Reliable in boilers and turbines, securing steady operation.

Real Results

In one US steel mill, Gotrays castable extended furnace lining life by 40%, cutting replacement frequency and labor costs. This boost led to a significant ROI, with less downtime and improved productivity — proving the value of our high chrome castable refractory.

If you want proven performance for your operation, Gotrays Chrome Corundum Castable offers durable, wear-resistant solutions tailored to your needs.

Installation and Usage Guidelines

Getting the best results from Gotrays Chrome Corundum Castable starts with proper installation. Here’s a simple step-by-step guide to help you through the process:

• Surface Preparation

  Clean the furnace lining thoroughly. Remove dust, loose particles, and oils to ensure good adhesion. Roughen smooth surfaces if needed to improve bonding.

• Mixing Ratios

  Follow the recommended water-to-castable ratio for your specific batch. Use clean water and mix uniformly until you get a smooth, flowable mix with no lumps.

• Pouring and Vibration

  Pour the mix carefully without trapping air pockets. Use vibration equipment to settle the castable evenly and eliminate voids. This step is key for strong, durable lining.

• Curing

  Allow the castable to set at ambient temperature for the initial phase. Then follow the gradual heating schedule in the manual to prevent cracking. Proper curing strengthens the lining and boosts erosion resistance.

Safety Notes

When handling chrome oxide (Cr2O3) in the castable, take these safety steps:

• Wear appropriate PPE including gloves, safety goggles, and dust masks
• Ensure good ventilation during mixing to avoid inhaling fine powders
• Follow all OSHA guidelines for refractory materials handling in your facility
