The relative viscosity of the liquid-glass slurry filled with cooper slag
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 3
Abstract
Objective is to determine the influence of the content of copper slag in liquid-glass slurry, temperature and specific gravity of the liquid-glass applied on the value of its relative viscosity. The relative viscosity of the refractory slurry was determined by a standard technique in the viscometer VZ-4. The results of investigation of influence of cooper slag serving as filler on the relative viscosity ofglass-liquid slurry depending on its temperature, fullness and density of the of sodium liquid-glass are presented. It is found that with increasing copper slag content in refractory slurry (from 0.1 to 0.4 kg per 1dm3 of liquid-glass), the specific density of the liquid-glass applied (from 1150 to 1300 kg /m3) and temperature decrease (from 50 to 20 °C), its relative viscosity increases according to a power law. As a result of the mathematical processing of the experimental data, the empirical relationship has been obtained, the value of the relative error is less than 2.6%. The data obtained allow us to take decision rapidly on the necessary adjustment of the refractory slurry composition in the foundry shop conditions.
