meTECH Wear Resistant Liners are sourced from the world's biggest hardfacing productions for compound Wear Plates in Germany.
These Wear Plates are economically produced with a special Hardfacing "Metal-Arc process" of high deposition rate, with low dilution.
meTECH Liners are highly abrasion resistant Wear Plate which offers long life cost effective performance where severe Wear is experienced. In addition to outstanding Wear characteristic meTECH Liners are resistant to impact, heat, corrosion and chemical attack, making it ideal for applications in a variety of Industries including Concrete Quarrying, Sand Production Power generation and many others.
Advantages:
• 64 - 68 Rockwell
• High Chrome Carbide

| VAUTID METAL-ARC PROCESS |
| |
Advantages of the VAUTID Metal - arc Process:
In case of the Metal-arc process the Cr-powder flows into the arc which is built up between baseplate an the solid Fe wire.
This VAUTID process provides a lower dilution with the basic material. Due to the lower dilution we have a higher concentration or Cr. Carbides, due to this fact the appear as PRIMARY CHROMIUM CARBIDES which give a sufficiently higher abrasion resistance.
Hardness as well as abrasion resistance remains the same over the whole thickness of the plate.
Other plate have only a small section (2 mm) with PRIMARY carbides.
Further advantages:
• Better overlapping of
neighboring
welding beads with much hardly any pores.
• More even surface, no waves of the welding beads |

Structure of a one layer flux-cored (mm) wire hardsurfacing:
The dilution with the base material reduces the Cr and C content. This leads to a lower percentage of primary chromium carbides. These exist only close to the surface. |
|
Structure of a VAUTID wear plate (mm),with One layer of hardsurfacing by means of the VAUTID-Metal-Arc-process:-
The Structure of the hardfacing layer shows a high content of primary chromium carbides already close to the base metal.
A further important characteristic of quality is non-melted powder particles, which proves that the welding material is saturated with components of the alloy.

| Highly Wear Resistant means long Lifetime. |
The decisive advantages:VAUTID Wear Plates cannot be compared with sheets Hardfaced with the conventional method.
For their manufacture we employ the VAUTID- Metalarc-Process:- |

| Hardox Liners |
| |
The sides and bottom of a concrete mixer are subjected to sliding wear. However, the Wear applied to the bottom is at a higher pressure.
Even if the wear is relatively moderate, the useful life is important to the economic. In this case, HARDOX 500 has proved to be the most appropriate material.
For the best possible useful life, HARDOX 600 is used for the bottom of the mixer.There are great many steel grades and a
great many application for which Steels are used. The choice of Steel is dictated by the application area, the function and the total production cost.
Hardox is the No:1 quenched and tempered Wear Resistant Steel which is produced in hardness of upto 640 HB. Hardox Liners are available as running replacement of the both Plants and Mixers Wear Parts, and as a contingency stock in the event of break down.
meTECH offer the widest range of alternative abrasion resistant concrete mixer linings. Our application engineers have developed a high level of expertise in this specialist field and would be pleased to discuss your application in further detail.

| Ceramic Liners |
| |
meTECH Ceramic Liners have successfully proved together with all mixer manufacturer and type. The standard tiles are fabricated with a wall thickness of 13,17 and 25 mm. These tiles are glued directly onto the bottom of the mixer. The high performance adhesive based on epoxy resin gurantees high strength, no ageing and avoid creeping brittleness.
The remaining elasticity has an absorbing effect against impact energies. The glue has a setting time of about 24 hrs. Therefore the just lined mixer can be reintegrated in processing very quickly.
meTECH alumina Ceramic Liners are one of the most Wear resistant material offered on the market today.
The Ceramic mixer linings has evident advantage in processing:-
- Higher Service Life
- No impurities caused by iron - abrasion
- Resistant to environtmental influences.
Because of the outstanding propertries of alumina e.g. high hardness, high wear and corrosion-resistance, from stability and low density- ceramic linings achieve greater durability than those of steel or cast.
