SouthAfrica UHPC Wear protection lining of a BF Top Gas Cleaning system

BF Top Gas Cleaning

The Paul Wurth gas cleaning system for the Newcastle Steel plant blast furnace was one of several Paul Wurth gas cleaning systems we supplied with UHPC wear protection complete the wear protection. The installation was carried out by a local installation company.

We installed the anchors directly at the steel construction company. The UHPC wear protection lining was then lined on site at the steel mill in the installed condition. The total lining area was approximately 400 sqm. The layer thickness was specified by the plant builder from 25 mm to 40 mm

depending on the area in the cyclone.

UHPC Mortar 2000 HT was specified by our customer as the wear protection material. UHPC Mortar 2000 HT is enormously wear resistant even at continuous temperatures up to 1200°C. The cyclone should have a normal average operating temperature of 400 - 500°C. 

However, it is possible that hot gases up to 1000°C may enter the cyclone uncontrolled from blast furnace.

 

The planned service life is at least 10 years. During these 10 years the blast furnace will not be stopped

and therefore repair of the cyclone will be possible only under very difficult conditions.

UHPC HT lined Blades /guide vanes for a Paul Wurth cyclone in a steel plant

Once again we supplied blades / vanes for a Paul Wurth dedusting cyclone. Over the last years we have manufactured and delivered more than 210 blades / vanes of different sizes. We delivered for new projects or for spare parts supply.
The blades are lined on both sides with 25 mm thick UHPC HT (high temperature resistant UHPC). 

Each delivery is extensively tested by us. 

It has been proven over the years that the blades manufactured by us can withstand the maximum loads in a blast furnace dedusting for years.

Companies which used UHPC Wear Protection in the last 25 years

 

We are always asked who has been used UHPC
Wear protection for the past 25 years. WPE DK our UHPC wear protection specialist, took the task to compile a list of companies who used UHPC as wear protection during these years.

The list includes plant system supplier and plant operators in
worldwide. The list should give an impression of where
UHPC is already standard as wear protection everywhere. In
In many cases, plant operators have the UHPC material
installed by own fitters.

Here is the list:
The company names can change over the years and some
companies probably have merged with other companies.

New build and repair of sewage treatment plants and sewers with UHPC concrete

Sewage treatment plants and sewers are exposed
to a permanent chemical and mechanical attack
by sewage from households and industry. Due
to the changing climate conditions and the resulting
extreme rain or flood masses, the systems and
channels are extremely stressed and damage that
their function is no longer guaranteed.

A material with high resistance to chemical and
mechanical attacks is necessary for the maintenance
of these systems.
This material should also be able to be processed

flexibly on site and should not require any complex
machinery.

Damage causes in a sewage treatment plant
- due to mechanical wear
- through frost and de-icing salt
- due to chemical attacks or solvents
- due to concrete corrosion in closed systems

UHPC Ultra High Performance Concrete
UHPC are special concrete products with a minimum
compressive strength of 130 MPa and a water/cement
ratio of less than 0.2.UHPC products can be used very
well for the rehabilitation of concrete - and steel structures.
UHPC products can increase to be rehabilitated
construction next to the corrosion protection even
with admixture of ceramic aggregates the static
bearing capacity.

Benefits of UHPC
- Easy installation as spray, mortar, cast
- Very high corrosion resistance
- Extremely wear-resistant
- Extreme low to no carbonation
- Usable at very high humidity
- Very high impact strength
- Extreme low chloride permeabilit
- Very high resistance to mechanical loads
- No pore formation
- Maritime and port water resistant    
- Installation in the water possible
- Duration resistant
- The standard drying time is under 48 hours
- Penetrates into the smallest joints and cracks,
   and closes them permanently
- Joint less installation
- Very good thermal shock resistance
- Absolutely frost and de-icing salt resistant
