K-GenesisX™｜Interview

Bringing the rest of the world a revolutionary product from Asia that extends the life of refractories in converters by more than 40%

TOUGHMAX™

TOUGHMAX™ is a type of refractory brick known as a “magnesia-carbon brick,” primarily composed of magnesium oxide and graphite. It is a highly regarded product that is not only used in Japan but has also earned high praise from customers in Taiwan.

A challenge that overturns conventional wisdom by eliminating drying process for monolithic refractories.

Dry-Free™

Conventional drying processes require 90 to 100 hours, during which time the temperature inside the furnace must be carefully controlled in tens of degrees Celsius increments. With the introduction of Dry-Free™, however, the drying process itself is no longer necessary, and the furnace can be started up with only the temperature rise necessary for incineration. As a result, start-up can now be accomplished in as little as eight hours.

After years of research, we succeeded in a groundbreaking reduction in clogging of the submerged entry nozzle that affects the quality of steel

EVERCLEAN™

EVERCLEAN™ offers an unprecedented level of resistance to clogging compared to conventional materials, while also exhibiting significantly lower susceptibility to corrosion and wear in the nozzle material.

Collaboration between humans and robots, creating a more comfortable workplace. Achieving efficiency and consistent operation by the technology, expanding options to attract valuable human resource.

REX-ROBO™

REX-ROBO™ is a robot developed to reduce the workload and improve safety in the steel manufacturing process. This project also aimed to add “Newer” to our corporate motto of “Better, Cheaper, Faster.”

Applications ranging from semiconductors to outer space by capitalizing on a low coefficient of thermal expansion and light weight. Exploring the limitless possibilities of ceramics.

NEXCERA™

In anticipation of the increasing demand for higher precision alongside the evolution of semiconductors, we began developing a material capable of achieving near-zero thermal expansion at room temperature ahead of our competitors around the year 2000. The result of that effort was the development of NEXCERA™.

Developing materials with high thermal insulation performance for the era of decarbonization

KROTECT™

KROTECT® is a thermal insulation material with an exceptionally low thermal conductivity compared to conventional products. By examining and optimizing various manufacturing conditions to maximize the material’s inherent properties, we successfully achieved the high performance of KROTECT®.

Light, strong and long-lasting. PLATECT™ is a setter that will change the firing field.

PLATECT™

Ceramic capacitors are indispensable to electronic devices. To overcome the shortcomings of zirconia setters used during their firing process, we began developing PLATECT® in the 1980s.

Towards a Symbiosis Between Refractories and the Environment: The Future Pioneered by “MAGreenX”, a Magnesia-Carbon Brick for RH Degassers

MAGreenX™

MAGreenX™ is a type of refractory brick known as magnesia-carbon brick, primarily composed of magnesium oxide and graphite. It is an environmentally friendly product that can replace magnesia-chrome bricks.

Delivering High Heat Resistance and Low Odor Without Coal Tar: A Next-Generation Taphole Clay Setting a New Standard for Blast Furnace Operations

AirGreen™

AirGreen™ is an innovative taphole clay developed to overcome the challenges of tar-resin-based materials. By minimizing the use of harmful raw materials, including coal tar—a known carcinogen—it is virtually odor-free and significantly reduces environmental impact.

Making “safety, security, and stability” even more certain

Stabilex™

Stabilex™ is more than just a product—it’s a consultative service that delivers high customer satisfaction by preventing trouble before it occurs. Through on-site visits, we review installation methods, maintenance practices, and propose improvements to ensure safe, stable operations and maximize product performance.

Co-creation of Towns and Businesses to Support a Recycling-Oriented Society

Neo Series™

Neo Series™, our recycled paving bricks, add color to cityscapes while promoting environmental sustainability. The Circular Economy Promotion Division of the Kitakyushu City Environment Bureau and Kurosaki Harima team members discussed the origins and features of Neo Series™ and the “Kitakyushu Eco Premium” program, which has long supported sustainable resource recycling in the city.

Revolutionizing Tertiary Air Dampers for the Cement Industry

K-Damper™

The K-Damper™ is a tertiary air damper engineered for cement kilns to withstand extreme temperatures, high gas velocity, and severe abrasion inside the tertiary air duct. Unlike conventional dampers with a steel frame coated in refractory castable, the K-Damper™ is constructed entirely from high-quality refractory materials with uniform thermal and mechanical properties, delivering exceptional structural stability and durability.
