Advantages of intermediate frequency furnace duplex short flow smelting process

Abstract: The information on the advantages of the intermediate frequency furnace duplex short-flow smelting process is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Around the energy saving and environmental protection of the foundry industry, there have been many successful experiences abroad, and Chinese foundry workers have also carried out a lot of work. Among them, the measures for the melting and heating system are mainly divided into two aspects: technical transformation of cupola and double short-flow smelting. (. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. Below are the details of the advantages of the intermediate frequency furnace double short-flow melting process. Around the energy saving and environmental protection of the foundry industry, there have been many successful experiences abroad. Workers have also carried out a lot of work. Among them, the measures for the melting and heating system are mainly divided into two aspects: technical transformation of cupola furnace and double short process smelting. (1) Technical transformation of cupola furnace is mainly through equipment structure transformation, adding Auxiliary equipment and the introduction of advanced equipment to replace the old equipment, in order to improve energy utilization, control pollution, achieve energy saving and environmental protection. After the preheating and air supply transformation, the cupola coke consumption is reduced by 5%; Oxygen-natural gas burner is installed in the tuyere, which can save 6% of coke, 7% of slag and 6% of SO2, and control dust pollution at the same time. (2) Duplex short-process smelting directly uses blast furnace molten iron for casting production to make full use of its latent heat , saves a lot of energy. Compared with raw materials such as pig iron ingots that are reheated in a cupola furnace for casting production, it can save 100% of coke, reduce slag by more than 95%, and reduce a lot of flue gas, dust, CO, SO2, HF emissions (melting Each ton of castings needs to emit about 800m² of flue gas, 2.8~12kg of dust, 8.0~96kg of CO, 0.08~0.48kg of SO2, 0.16~0.4kg of HF), and can also reduce the burning loss of Si and Mn elements by 10%~20%. %, the loss of Fe is reduced by more than 15%. From the above two aspects of the technical transformation of the cupola melting process and the use of the double short flow melting process, the blast furnace-intermediate frequency furnace double short flow and the melting process technology eliminates the need for the blast furnace The process of molten iron ingot and pig iron remelting effectively shortens the process flow, reduces energy consumption, reduces waste discharge, saves energy and is environmentally friendly, and is an energy-saving, efficient and cost-effective casting production method. The energy saving and emission reduction effect of the short-flow smelting process is very obvious. The above is the whole content of this article.
