Discovery And Perliminary Study Of The Iron Smelting Sites Of Han Dynasty In Henan Province

Human use of iron has at least five thousand years of history, as a matter of fact in the iron age is in the spring and Autumn Period Warring states. In The Eastern Zhou period, iron, based on the technology of copper, began to develop, through the accumulation of more than two hundred years and precipitation, to the Han Dynasty, iron smelting technology has finally achieved a leap, began a large-scale popularization of iron, and China is completely in the iron age.Henan province is located in the central plains hinterland, the geographical position is superior. Han period, the Henan province, because of its rich resources, developed traffic network, and many people, become the country’s economic center of gravity. Henan is earlier in China’s iron smelting technology, and its iron smelting technology in China is in the lead.In this paper, iron and steel industry as a starting point, Henan Province by the discovery of the Han Dynasty and the iron and iron smelting site displays smelting technology, introduced the development,investigate the causes and impact of the development of iron smelting industry.This paper is divided into 4 chapters: The first chapter is the introduction, mainly some basic description, including the significance of the topic and purpose, research status, research object, research methods and difficulties and related basic concepts are introduced. The second chapter mainly introduces the Henan region finds the ruins of iron smelting iron and Han period, and does the related statistics and analysis. The third chapter is on the Henan iron smelting technology is introduced, the 3 part includes the production equipment and raw materials, production process and summary. Production equipment and raw materials mainly introduced to oval shaft furnace smelting furnace represented, empty wall decarburization annealing furnace, blower system, furnace building technology and fuel; Production process mainly introduces the cast ductile iron technology represented annealing, fried steel technology, carburizing steel technology, steel technology and stickers to stack cast iron technology represented. The fourth chapter is related discussion and summary of the contents described above, and to explore including the contents of two aspects, namely to explore the reasons for the development and changes on the development of the Han Dynasty and the Han metal fabrication industry, metal fabrication industry to explore the impact on the economy and society of the Han dynasty. The fourth chapter is to explore and summarize the related content about the described above, explores the content includes two aspects, respectively is about the Han dynasty and Han iron smelting industry development causes of iron smelting industry, the impact of economic and social development and changes of Han dynasty. In Han iron smelting industry development was investigated, the paper analyzes the political environment, the management policy, copper smelting technology, and social needs four parties in the face of iron smelting industry development to promote role; To explore the influence of iron smelting industry development on economic and social impact of Han dynasty, this article will focus on three aspects: agriculture, handicraft industry and tombs.Through the above related discussion, the paper finally concludes: Henan Han smelting iron with its rich heritage and these remains represent advanced technology, can become the representative of the Han metal fabrication industry; Henan iron smelting technology as the representative of the Han Dynasty smelting technology a leading position in the world; the political, economic and other environmental factors contributed to the development of the Han Dynasty in the metal fabrication industry; development of iron smelting technology for economic and social prosperity of the Han make an important contribution.
