Enhanced Performance of Ladle Refractory Lining Through Innovative Castable Technology
For this purpose, we have developed our NORFLOW® selflowing castable refractory product line that offers high resistance to mechanical and chemical erosion, leading to longer lifetime, as well as ease in installation, and dismantling.
The high flexibility of NORFLOW® A 973 selflowing castable refractory product line is definitely a key advantage highlighted by our customers. Installation can be performed by casting or pumping in equipment ranging in size; from small ladles (<2 Ton) up to ladles of a size of 50 Ton molten metal volume, or as the working lining in pressure pour furnaces. Its advanced material composition aids in a very easy and consistent casting process.
Due to the self-flow properties, the installation is very time-efficient and requires no vibration equipment (e.g. vibrating needle). NORFLOW® A 973 selflowing castable refractory product line is designed to combine the most complex shapes by flowing freely in all areas of your equipment, while also exhibiting homogeneous material properties within the entirety of cast shape. The reduced water addition level needed for installation also helps to accelerate dry out. Once installed and dried-out, NORFLOW® exhibits an outstanding structure with low porosity and excellent penetration resistance against molten metal.
In addition, it shows a high resistance to slag formation and ease of slag removal. As reported by our customers, using NORFLOW® A 973 has lead to a significant increase in the lifetime of their equipment, reduced refractory material consumption, ease of installation, and increased availability of the equipment. Consequently, the adaptation of NORFLOW® A 973 selflowing castable refractory product line in our customer’s processes is strongly considered as an important influencing factor to improve product yield and operation cost competitiveness.
