The way of processing of vibrating refractory castables is largely responsible for the properties and durability of the final products and is fundamentally determined by their rheological character. However, it has not been possible to quantify the shear rate-dependent rheological properties, such as dynamic viscosity and shear stress, of vibrating refractory castables until now. A lifting sphere rheometer for measurements on vibrating refractory castables was developed and validated. Results from measurements under vibration show that the shear rate-dependent rheology can be well quantified.
