Smelting Converter Lead Copper Refining Metallurgy Machine Industrial Furnace
1. Introduction of Steel converter, copper converter and converter under 300T for metallurgy machine
Luoyang mining machinery Factory can design and produce various specifications of vertical/horizontal converter converter below 300t. Including steel-making converter, copper smelting converter, converter of various specifications below 250T, vertical converter, horizontal converter.
Converter steel-making is made of molten iron, scrap steel and ferroalloy as the main raw materials. Without external energy, the process of steel-making is completed in converter by the physical heat of molten iron itself and the heat generated by the chemical reaction between the components of molten iron. The converter is divided into acid and alkaline according to the refractory material, according to the parts of the gas blowing into the furnace with top blowing, bottom blowing and side blowing; According to the type of gas for air converter and oxygen converter. The bof is the most commonly used steel-making equipment because of its fast production speed, large output, high output of single furnace, low cost and less investment. The converter is mainly used for the production of carbon steel, alloy steel and copper and nickel smelting.

3. Case related to steel-making converter for metallurgy machine
Citic Heavy Machinery Co., Ltd. has signed contracts with Shandong Fulun Iron and Steel Co., Ltd. and Hebei Xingtai Delong Iron and Steel Co., Ltd. for one 150-ton large vertical steel making converter and two 80-ton vertical steel making converter respectively. This is another major breakthrough made by CITIC Heavy Machinery Company in the field of metallurgy after the successful manufacturing of shandong Laigang 120 ton vertical converter. Especially the 150-ton steel-making converter of Shandong Fulun Iron and Steel Co., LTD., with compact structure and large steel storage capacity, the furnace body weight reaches 530 tons, making it the largest steel-making converter in the history of the company. The signing of these three metallurgical converter contracts is of great significance for the company to further develop the large metallurgical converter market.
March 5, 2007, in Zambia Chambishi copper smelter project bidding, our company stood out with strong technical advantages, won two international advanced level φ 4×11.7m copper smelter converter. This is our company vigorously implement the famous brand strategy, in the international market to achieve another major breakthrough.
Zambia Chambishi Crude copper Smelter project is jointly invested and constructed by China Nonferrous Metals Group and Yunnan Copper Group Corporation with a total investment of more than 220 million US dollars. It is China's resource project in Africa and has far-reaching political and strategic significance. The state attaches great importance to the construction of the project. Vice Premier Zeng Peiyan personally attended the signing ceremony.
