Title

Design of a Non-isothermal Corrosion Test Apparatus

Abstract

A furnace has been designed, constructed, and tested for non-isothermal corrosion testing of refractories. The major drawback of the standard isothermal testing method is that the entire test specimen is at same temperature, which is not simulative of most industrial furnaces. For this project, a bottom loading furnace system was designed to impose a reproducible, controllable temperature gradient across refractory specimens. The system includes a hydraulic lift to raise the specimen into place against a rigid refractory that allows for precise specimen positioning. The system also allows for insertion of corrosive materials such as metal or glass from above after the specimen has reached a steady state. The furnace is designed to attain the maximum temperature of 1700°C. To validate the design, refractory specimens were heated and the temperature gradients through the specimens were measured. Temperatures were measured at various points horizontally and vertically in the refractory to quantify the temperature gradient.
