ABSTRACT:Steel is the backbone of the national economy, it is the most commonly used in electric furnace steelmaking equipment. raw material of steelmaking is scrap, energy is an electric, not only is the recycling of resources, but also protect environment. Furnace cover lifting and rotary device can make the furnace cover capable of tilting and electric furnace body at the same time, but also can produce the furnace body and the relative displacement of the show, realize the charging requirements. Usually, electric furnace cover lifting and rotation is driven by hydraulic pressure, which can make the furnace cover in the work process can shake to avoid electrode broken impact and reduce the pressure, in order to ensure the safety and reliability of electric arc furnace smelting the normal operation. Therefore, it is very important for the rational design of furnace cover device has the significance.
This paper mainly introduces the design of 90t furnace for a steel cover lifting and rotating device. The main contents are: the design and calculation of hydraulic system, the scheme argumentation, furnace cover support part design, as well as the installation, use and maintenance.
