K-Damper™

Features of K-Damper™

K-Damper™ is a tertiary air damper* designed to support stable operation of cement rotary kilns, where durability is essential under high temperature, high-velocity airflow, and highly abrasive conditions.

*Air damper is a device that regulates the supply of air to maintain optimal combustion conditions.

Uniform properties with high-quality materials	Made from materials with excellent thermal conductivity and thermal expansion characteristics to ensure stable performance.
Efficient airflow generation	The Venturi tunnel* creates a controlled airflow for improved combustion efficiency.
Pre-assembled delivery	Supplied fully assembled, eliminating the need for additional work.
High durability in harsh environments	Uses high-grade refractory materials to resist wear, alkali corrosion, and material buildup.

*The Venturi tunnel utilizes the Venturi effect by narrowing the flow path to increase velocity and reduce pressure, enabling efficient gas flow distribution.

Advantages of K-Damper™

1 Low-risk reversible design

By covering the Venturi tunnel, it can also function as a conventional air damper.

2 Significant productivity improvement

Longer service life reduces kiln shutdowns, dramatically improving cement production efficiency.

3 Reduction of CO₂ emissions

Fewer shutdowns lead to lower fuel consumption and reduced CO₂ emissions.

K-Damper™

Revolutionizing Tertiary Air Dampers for the Cement Industry

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.

Strategic Products

Steel

TOUGHMAX™ $Background$

Features

Compared to conventional magnesia-carbon bricks, these refractory bricks are less prone to internal crack growth and less susceptible to breakage.

Durability is high, so...

Equipment service life is longer, reducing customers’ refractory consumption
Carbon dioxide emissions from blast furnaces are reduced by increasing scrap (reducing hot-metal)

Steel
Non-
ferrous
Incine
ration

Dry-Free™ $Background$

Features

This is a groundbreaking monolithic refractory that eliminates the need for a drying process, significantly reducing heating time before use and making furnace startup easier.

No drying process is needed, so...

Construction and repair periods can be shortened, increasing furnace operation rates and improving productivity
Fuel consumption is eliminated, reducing CO₂ emissions

Steel

EVERCLEAN™ $Background$

Features

Used in immersion nozzles and similar components, this technology has the characteristic that unwanted substances (inclusions) in molten steel are less likely to adhere to the nozzle and cause clogging.

Prevents nozzle clogging, so...

Molten steel flow stabilizes in the mold, leading to dramatic quality improvement
Reduced frequency of nozzle replacement leads to improved productivity and energy savings

Robots
Steel

REX-ROBO™ $Background$

Features

This product automates heavy physical labor in hot environments by using robots, thereby achieving work safety, security, labor savings, and reform.

Due to automation with robots...

Workers are liberated from heavy labor in harsh environments with high temperatures, dust, etc.
Labor-saving lowers the risk of being unable to secure workers and thus improves business sustainability
