The invention relates to solar energy utilization, in particular to solar energy collection by using a point focusing solar mirror and application of the point focusing solar mirror to a moving point array solar smelting system. The moving point array solar smelting system at least comprises one or one group of point focusing solar mirrors, at least one smelting device and a tracking control device for control, wherein the solar mirrors are arranged on a solar mirror support; smelting devices are arranged on a smelting device support, and are arranged in a punctiform area focused by the solar mirrors and above or below the solar mirrors; and the tracking control device controls the solar mirrors to focus sunlight to at least one smelting device when the sunlight changes, the smelting devices move in the process that the solar mirrors track solar energy, and each or each group of solar mirrors select the smelting device capable of reaching the highest solar energy utilization efficiency for focusing, so that the solar energy is tracked, focused and utilized.
