Iron blast furnaces[edit]Blast furnaces are still an important part of modern ironmaking production. Modern furnaces are very effaicient, including Cowper furnaces for preheating the blast and employing recovery systems to extract heat from the hot gases exiting the furnace. Industry competition dri

Vacuum induction melting (VIM) uses an electric current to melt metal in a vacuum. The first prototype was developed in 1920. [1] Induction heating induces eddy currents in the conductor. The eddy currents create a thermal effect to melt the metal. [2] Vacuum induction melting has been used in the a

Smaller arc furnaces may be adequately cooled by circulation of air over structural elements of the shell and roof, but larger installations require intensive forced cooling to maintain the structure within safe operating limits. The furnace shell and roof may be cooled either by water circulated th

Ladle refining furnace is an important metallurgical equipment used to refine the molten steel melted in primary smelting furnace (electric arc furnace, open hearth furnace and converter), and can adjust the molten steel temperature and process buffer to meet the requirements of continuous casting and continuous rolling. Ladle furnace is one of the main equipment for refining outside the furnace.

Precautions for the operation of LF furnace refining technology 1. Inspection and preparation before refining of power distribution workers 1.1 Carefully check whether the selector switches are correct according to the equipment operating regulations. 1.2 Whether the high-voltage electrical system is normal. If there is any abnormality, report to the dispatching room and notify the electrical personnel to deal with it in time.
