Abstract

In this paper

it is described how to choose the exothermic agent for the riser of aluminium alloy castings. At the same time

it points out the effect of the composition of exothermic agent on its properties. The experiments and practical applications show that the exothermic agent used decreases the volume of the riser more than half. This agent has a lot of advantages such as abundant raw materials

good combustibility

easy use and less rate of absorbing moisture etc.
