Abstract

The invention provides a preparing process of the Longquan sword. The process comprises following steps that archaized low-sulfur white iron is selected to serve as a raw material, a rough blank stamping device is adopted to stamp the archaized low-sulfur white iron to form the early form of the Longquan sword, and rough hammering, fine hammering, shaping, quenching, polishing, tempering, carving,shaving and assembling are carried out. The traditional Longquan sword making process is improved, the performance of pig iron is changed, the archaized low-sulfur white iron raw material is adopted,the Longquan sword suitable for a dance studying person with the sword for keeping health for use, and the Longquan sword has the beneficial effects that the sword body has strength and toughness; the rear tail of the sword body is elastic, and free in stretching; thirdly, the sword body is bright; fourthly, t he archaized low-sulfur white iron raw material is adopted, and it is ensured that themade Longquan sword is resistant to wear and oxidation and not prone to rusting.
