The invention discloses a template system of a magnetic-levitation linear track beam and an application method. The template system comprises a bottom die used for bearing the track beam in the linear shape, side dies, end dies and multiple adjusting assemblies. The side dies comprise side die panels longitudinally arranged along two sides of the linear track beam. Multiple frameworks are arranged outside of each side die panel. The end dies are arranged along two end portions of the track beam. A horizontal-moving device enabling each end die to longitudinally move along the track beam is arranged outside of each end die. The outside of each framework is provided with at least one adjusting assembly capable of adjusting perpendicularity and transversal displacement of each framework. The template system comprises the mold die, the side dies, the end dies, the adjusting assemblies and horizontal-moving devices and is simple in structure, high in adjusting efficiency and easy and convenient in detachment and installation and suitable for prefabrication of the linear track beam. The application method of the template system is employed easily and conveniently with high adjusting accuracy and used for conveniently detaching and installing dies. The adjusting accuracy can help to enable linearity accuracy of the linear track beam in transverse, longitudinal and vertical directions to range from -5mm to +5mm so that prefabrication quality of the track beam is ensured.
