| Rheo-flow (RF) |
 |
| AGC Ceramics's self-flow castable, the Rheo-flow (RF)
Series is a low-cement type self-flow castable with high strength and density.
Although conventional low-cement castables were installed by vibration casting
using vibrators Rheo-flow optimally controls the rheology properties of super-fine
powder, resulting in a vibration-free installation. It also has a self-flow mechanism
and is therefore applicable to varied part shapes. This feature has also allowed
it to be pumped longer distances and to higher work places using a special pressure
pump, resulting in a considerable reduction in construction process and time. |
| Characteristics |
| - |
It is installed by a self-flow method, therefore
does not require a vibrator. |
| - |
Using a special pump, it can be pumped to
long distances. |
| - |
Extremely low porosity and permeability,
while high in strength, abrasion resistance and hot strength. It has the comparable
properties as a vibrating method type (compared to AGC Ceramics's Ramcrete). |
| - |
Products range from high alumina type, alumina
type, Drysic type and acid-and-water resistant type. |
| Gunning Rheo-flow (GRF) |
|
Gunning Rheo-flow is a wet method using AGC Ceramics's
Asahi Gunning Rheo-flow (AGRF) method. AGC Ceramics created AGRF technology by combining
Rheo-flow's self-flow and front-edge quick-setting technologies. AGC Ceramics holds industrial
property to this product.
Low-cement self-flow type materials are completely kneaded, pumped and gunned,
therefore, quality is equivalent to that of the conventional low-cement castables. |
| Characteristics |
| - |
Gunning method results in an equivalent
performance to that of low-cement castables. |
| - |
Extremely low porosity and permeability,
while high in strength, abrasion resistance and heat strength. |
| - |
Casting method required several procedures
because of molds, but AGRF method does not require molds and can significantly
reduce construction time. |
| - |
Significant reduction in powder dust compared
to dry and semi-dry methods. |
| - |
Pumping distance reaches 40m vertically
for standard types, reaching a maximum of 70m, allowing application for large-scale
plant constructions. |
| - |
Construction speed is at maximum 2 - 4t/H,
making it possible for large-scale constructions with short deadlines, while its
pumping parts and tip nozzle are very light, weighing 2 - 1-3/4B. |
| - |
Products range from high alumina type, alumina
type, Drysic type, acid-and-water resistant type, light insulation type and very-light
insulation type. |
