SMOKE CHAMBER FOR EVALUATING FOUNDRY SAND SHAPES AND ITS METHOD OF USE

摘要

A smoke chamber (10) for determining the amount of visible smoke emitted by a foundry core/mold resin system is composed of an elongate chamber having a proximal end (24), a distal end (18), and sides. The chamber is fitted with air inlet at at the proximal end, a smoke outlet at its distal end, and a sample station disposed between the air inlet and the smoke outlet. The sample station includes a sample holder and furnace for heating a sample placed in the sample holder. The chamber also includes a light assembly disposed along one side of the chamber from the sample station to the smoke outlet. A light detection assembly is disposed on a chamber side opposite the light assembly for detecting light emitted form the light assembly.
