Chinese Foundry Hometown Botou
Botou casting is one of the famous non-material cultures in China. It has a long history, which can be traced back to more than 1300 years with written records. It is one of the birthplaces of China's modern industry. Botou casting has developed with three stages of agricultural civilization, industrial civilization and modern industrial civilization. Botou was originally Jiaohe County. According to the written records, because of the frequent floods in Jiaohe, farmers made a living by smelting iron, and even reached Brunei in the South. This is an earlier record in the historical materials of the Ming and Qing Dynasties, but it is not the earliest history of Botou casting, but the fact that casting has become a production industry. It is difficult to determine when Botou casting first originated. In the farming society, Botou casting is mainly based on agricultural production tools, but also has a large number of daily necessities and weapons, including many handicrafts. The farming period was very long. Botou Foundry produced farming tools, daily necessities, artworks and weapons during this period, and developed slowly. After the modern industrial revolution, during the period of the Republic of China, there were more than 200 pig iron plants in Botou, with four or five thousand workers and a capital of more than three million yuan. Almost all provinces in China had iron plants held by Botou people. For example, Zhang Zhidong founded the Hanyang Iron Factory. As a Cangzhou native, Zhang Zhidong could not be ignorant of Botou casting. He has many northern staff around him. The establishment of an arsenal and an iron factory cannot be separated from casting technology. Although we do not have much information at present, we can speculate that there must be Botou casters there. At the stage of opening the iron plant, Botou Foundry has not only simply served the production of agricultural civilization, but also made immortal contributions to the development of national industry and the prosperity of the people. After the founding of New China, Botou Foundry entered the stage of machinery industry. A large number of agricultural machinery and equipment such as water pumps and waterwheels were manufactured. At one time, the number of people casting in Botou reached more than 80000. The Ministry of Agricultural Machinery of the People's Republic of China named Botou plowshares as historical famous brand products, with an annual production of several hundred thousand pieces. When Handan Xingtai Iron and Steel Base was launched, Botou undertook 299 kinds of 190000 matching technologies, 1800mm large-diameter valves, large coking furnace door frames, large casting plates and 2000kW motors, which are the gold projects never seen in Botou's casting history. At that time, Vice Premier Li Xiannian visited Botou twice. Botou Foundry has entered the modern production industry of production machinery and equipment, instruments, general machinery, auto parts, etc. Botou Foundry has entered the spring of development since the country implemented the "reform and opening up" policy. Especially in the past 20 years, the automobile mold industry derived from the traditional casting industry has developed rapidly. Botou automobile mold industry has become an industry team with high popularity and the most obvious cluster effect in China, no matter in terms of overall scale, R&D capability, or market space and development speed. Botou now has 28 automobile mold enterprises, accounting for 25% of the total number of automobile mold enterprises in China. At present, the city is mainly engaged in the production of mid-range automobile dies, which can provide stamping dies for vehicle covers for medium and light pickup trucks, SUVs, bread and other automobile manufacturers, and also provide inner liner dies for cars. It has maintained good business relations with more than 40 well-known automobile manufacturers, such as FAW Group, Jiangxi Isuzu, Hafei Automobile, Guangzhou Honda, Japan Honda, and has a high market reputation.

Jiahe, the capital of Jiangnan in China
Jiahe Foundry has a long history. It has been about 200 years since Tiangangtou Village began to cast plowshares. Jiahe Foundry has been constantly innovating and developing, and gradually developed into a major industrial county focusing on the foundry industry, enjoying the reputation of "casting capital in Jiangnan". Jiahe casting and forging industry attaches importance to the development of green casting. According to the different conditions of enterprises, there are key, orderly and diversified business development and innovation. In terms of casting materials, Jiahe Foundry has been constantly developing materials that are more suitable for users' products. It not only develops new materials that users need for new products, but also considers improving the quality of users' products, improving functional performance, and improving the materials of supplied castings. In order to improve the hardness, toughness, corrosion resistance, weight reduction, rare metal consumption, cost reduction and cutting performance of castings, research and development should be carried out to improve the casting materials. With the development of industrial technology, precision cast steel, nodular cast iron, vermicular cast iron and nonferrous alloys will be developed in the future. In recent ten years, in order to meet the requirements of energy conservation and environmental protection, as well as the national regulations on CO2 emissions, the automotive industry has put forward higher and higher requirements for the material performance of diesel engines. The material of gray cast iron cylinder head can no longer meet the needs of the automotive industry. Vermicular cast iron has good strength, heat conductivity, wear resistance Corrosion resistance and heat fatigue resistance. Cylinder head is the key basic part of diesel engine. The gray cast iron cylinder head produced by traditional process can no longer meet the requirements of modern automobile industry. The production of diesel engine cylinder head with vermicular cast iron has achieved good results. Cupola and electric furnace smelting process: among the smelting equipment currently used by Jiahe Foundry, the cupola accounts for about 60%, the electric furnace accounts for about 40%, and the cold air cupola accounts for about 60% of the total number of cupolas. The hot air cupola generally adopts the physical hot air supply mode, and the hot air temperature range is 150 ℃ - 250 ℃. It is the consensus of foundry enterprises to save energy, protect environment, reduce consumption, increase smelting output, and obtain high temperature and high-quality molten iron. The hot air and water-cooled cupola with long furnace life has not been popularized in Jiahe. The existing cupola of Jiahe Foundry Enterprise should properly change the air supply mode, furnace body structure, easy to use top heat storage water-cooled cupola, separate secondary air supply, oxygen injection from the cupola tuyere, natural gas, coal powder and metallurgical powder, which will improve the melting effect of the cupola. Zhejiang University of Technology has designed an induction furnace in front of the cupola for a foundry enterprise in Chaohu to raise the temperature of molten iron and ensure the outlet temperature of molten iron. In the future, cupola will develop in the direction of oxygen enriched air supply, natural gas, thermal storage, hot air water cooling, large tonnage, environmental protection and automation.
