The composite pressing-in mass for repair of blast furnace , which
is made of good-quality fireproof materials and bonding agents, can
enhance the integrity of blast furnaces and effectively avoid the
phenomena of gas leakage and redness and burning of furnace shells.
Moreover, it has obvious functions of improving field environment,
ensuring field operation safety, speeding up the production rhythm
of blast furnaces and improving efficiency of iron-making
production, and is highly praised by customers.
Introduction to Construction Process
The grouting indentation process is a novel repair construction
method. By the grouting indentation process, a high-pressure mortar
pump is used to transfer all materials to the damaged parts of the
furnace lining by pipes, and the indentation materials can form a
lining with a new structure or fill the gaps so as to achieve the
effect of protecting the furnace body.
Low degree of porosity, high structural strength, stable volume and
good integrity after solidification;
High constructional flowability;
High filling performance;
Stable high-temperature performance;
Good sintering performance;
Easy construction and convenient operation
The blast furnace wall-making indentation mortar is applied to the
indentation wall construction of furnace bodies, upper parts of air
ports, etc. of blast furnaces as well as the indentation wall
construction of hot air main pipes, branch pipes, bustle pipes,
ascending pipes, etc. of blast furnaces.
