 D-Block
is made of stacked multiple layers of blanket which are sewn together
under compression, and is available in four temperature grades ranging
between 1260ºC and 1600ºC. D-Block offers superior durability,
resiliency, uniformity and dimensional accuracy. Blook can be mortared
into place over existing refractory using either Module Cement or
Module Cement HS, depending on the furnace operating temperature.Module
Cement is a mixture of refractory mortar and
inorganic binders. It is an air setting mortar exhibiting good adhesion
at room temperature and strength at elevated temperatures. Many furnace
operators have chosen this method for upgrading the performance of
existing linings because of the ease, speed, and simplicity of installation.

It is often a more
attractive alternative than completely relining a unit due to
the lower cost and shorter downtime.When D-Block is to be used
as a complete furnace lining, a choice of attachment systems
from -B,
-T, -S1 and -S2 is provided to meet a wide range of
application needs. As an optional installation, a selection
of coating materials is provided to increase resistance to slag
and alkali attack, improve hot gas erosion resistance and reduce
thermal shrinkage of ceramic fiber block lining. |

| D-BLOCK-B |
|
D-BLOCK-S1 |
| This
is the standard attachment system. D-Block-B is attached to
the furnace shell with a flanged Nut and Module Stud that has
been welded to the furnace shell in a pre-engineered installation
pattern. Module Stud |
 |
|
Stud
welding is not required for this system.A stud bolt attached
to the block anchor permits D-Block-S1 to be fastened with a
nut from the outside of the furnace shell. |
 |
|
| D-BLOCK-T |
|
D-BLOCK-S2 |
This system offers
high installation speed.
D-Block-T is installed by pushing it toward the furnace shell,
whereby a specially designed speed clip attached to the block
anchor is locked with the threads of the Module Stud. |
 |
|
Provided with 2
pieces of Z-shape steel and 4 bolts, D-Block-S2 is designed
for installation on such structural steel components as angle,channel
and beam of a furnace without shell. |
