bronze Based on Continuous Improvement

This can also been confirmed in terms of archaeological materials. According to the Henan Provincial Museum in 1978 archaeological report on the Henan Han Dynasty metal fabrication technology of a paper record, since the liberation, in Henan Province alone had discovered iron smelting sites in the Han Dynasty 15, the largest area of 120,000 square meters. Archaeological 1978 contained in the nine Western Han Dynasty Chang'an arsenal to explore reported that the unearthed bronze weapons in addition to a small number of bronze weapons, the vast majority of knives, halberds, armor-level iron bronze swords, arrowheads, bronze weapons, only the iron arrowhead reached more than 1,000 pieces. Archeology 1975 4 contained in the city is Han Tomb Excavation Report also said that the weapons unearthed in the ground, there are large amounts of iron bronze swords, iron arrowheads. We are going to discuss the Animal Mask and deformation pattern of bronze.
A piece of iron armor, halberds and ring the first knives and general iron are carburizing steel or mild steel. And the Western Han Dynasty official attention, be turned over to the government-run metal fabrication are not unrelated. Eastern Han Dynasty unearthed large amounts of iron bronze weapons, the most representative Shandong Cangshan unearthed the early Eastern Han Yong-six years of iron knife, iron bronze weapons Xuzhou Eastern Han Dynasty built the first two days years of steel and bronze sword unearthed, after the identification is fried steel as raw material, made after repeated folding forged, welded to the manufacture of bronze weapons technology has entered a mature stage. bronze retained its significance as symbols of power divinity in the early Bronze Age of Chinese civilization. The Eastern Han Dynasty, metal fabrication technology invented drain away the water before the water power instead of human force of the blast method, effort less the effectiveness of large, enhanced firepower.
 Tima high furnace temperature, and coal used as fuel metal fabrication technology raise the level. these bronze weapons production technology improvement and development of bronze weapons production material and technological development as a basis in the Spring and Autumn before, due to the low level of development of material production, bronze weapons production and use of bronze. Bronze lead content is too small, not enough toughness, crisp, easy to break, so the above weeks bronze sword is impossible to create. Next is about the dragon pattern of antique bronze. The reason why copper bronze sword after the aforementioned unearthed in the Spring and Autumn growth, improved copper casting technology. The test found bronze swords body is embedded with two different levels of bronze casting made. The Ngok two tin bronze sword, some as high as 19.88% (high hardness), the bronze sword in the ridge to join the more lead (high toughness).
This bronze sword is characterized by two Ngok both to ensure sharp and effective way to enhance the seismic performance of a bronze sword in the battle ridge, so that the bronze sword [not easy to break, greatly improving the quality and long bronze sword made more. Of the Qin and Han's iron and steel smelting technology developments of iron or steel, bronze sword longer. The halberds produce up to mass production and equipment to the military, but also a basis for the material and technical development based on continuous improvement and development process of change. But bronze was the discovery of the last Shang Dynasty capital at Anyang in Henan Province in 1928. This can be confirmed from the cultural relics unearthed in the literature. Laid a good material and technical basis. 67 workers, such as the Temple work week is the abbreviation of the Temple workers workers' Week.
