It is necessary to reduce the rate of heating in order to determine if the substance is pure or impure.  Because pure compounds have the tendency to melt at a high temperature whereas the impure substance has the tendency to melt at a very low temperature that’s why the effect of faster rate of heating might give incorrect result of compound melting point.
