THE PERFORMANCE REQUIREMENTS THAT HAVE TO BE MET BY MOULDS AND MOULD MATERIALS DEPEND ON THE SPECIFIC APPLICATION AND THE LEVELS OF STRESS INVOLVED.
These stress levels are mainly predetermined by the machine and casting parameters, which means that many different cast shapes are needed, depending on the type and construction of the mould. KME develops and supplies the whole range of mould tube geometries and dimensions in use today, from small rectangular tubes right through to large-format round mould tubes. Our customers can select from various tapers and special internal geometries, such as WAVE® Mould Tubes or Textured Mould Tubes.

CONVENTIONAL MOULD TUBES
KME special Products & Solutions develops and supplies the whole range of mould tube geometries and dimensions in use today – from small rectangular or square to straight or curved tubes right through to larger format standard mould tubes.
WHEN DESIGNING A NEW MOULD, THE CORRECT PROFILE MUST BE CHOSEN IN ORDER TO ACHIEVE HIGH PRODUCT QUALITY, OPTIMAL CASTING SPEEDS, SMOOTH CASTING OPERATIONS AND LONG SERVICE LIFE OF THE MOULDS.
A good example of this are the requirements placed on modern mould plates for nearnet-shape-casting processes which have been developed in recent years.

STANDARD MOULD PLATES
The design and manufacture of mould plates for bloom and slab casting machines, whether furnished with cooling slots or deep-hole drills, is a major part of KME’s product range. For these applications, KME delivers a comprehensive selection of mould materials and coatings. KME has developed various technology packages for the continued development of the moulds used in the casting of bloom shapes. Based on a precise analysis of the cooling water flow and the load on the moulds arising from the process, an improvement in the service life can often be achieved through local optimization of the cooling geometry.
TODAY KME CASTING WHEELS ARE USED THROUGHOUT THE WORLD IN ALL TYPES OF PLANTS.
In order to optimize the service life of the casting wheel, and with regard to the specific stresses encountered in the operation, KME Special Products & Solutions has developed different high-end materials like CuAg, ELBRODUR® G and ELBRODUR® GF.
THE EXTREME STRESSES TO WHICH DAM BLOCKS ARE SUBJECTED WHEN OPENING AND CLOSING THE BELT DURING A ROTATION REQUIRE HIGH STRENGTH AND HARDNESS TO PREVENT PREMATURE MECHANICAL WEAR.
At the same time, the material must have good thermal conductivity for high-speed casting applications, and must not be sensitive to the formation of thermal shock cracks. The KME developed alloy OSNISIL® G, a material for dam blocks used in twin-belt type continuous casting machines, is the perfect solution for the required properties mentioned above.
MOULDS ARE SUBJECT TO HIGH THERMAL AND MECHANICAL FATIGUE STRESSES WHEN CASTING NONFERROUS METALS IN (THIN)STRIP CASTING.
Mould materials for such applications must satisfy high strength requirements even at elevated temperatures. At the same time, a minimum ductility is required to prevent cracks in the material from spreading.

- Increase lifetime for crucibles and base plates
- Reduce distortion
- Reduce mechanical damage

INTEGRATED STEELWORKS USE BLAST FURNACES AS A MEANS OF SUPPLYING PIG IRON.
For high productivity levels to be achieved it is crucial that the downstream casting plants and rolling mills are continuously supplied with iron. Throughout the world, KME’s cooling elements play a vital role in ensuring that blast furnaces are readily available and consequently achieve a high level of productivity.

COPPER STAVES
Modern-day copper stave coolers insulate the outer shell from the process heat generated in highly stressed furnaces. Yet, depending on where they are positioned within the blast furnace, they will be subjected to differing levels of thermal load.
Throughout the world, KME Copper Staves play a vital role in ensuring that blast furnaces are readily available and consequently achieve a high level of productivity. KME was involved in the development of Copper Staves from the very beginning and is also the owner of the basic patent. Copper Stave cooling is today the method utilized in leading blast furnaces worldwide.
