Large-scale direct current electric arc furnace continuous smelting high titanium slag electrode adding device and use method thereof

Abstract

The invention discloses a large-scale direct current electric arc furnace continuous smelting high titanium slag electrode adding device and a use method thereof. The electrode adding device comprises an electrode trolley (3), an electrode holder (6) and an electrode base frame (1), wherein the electrode trolley (3) is connected with a lifting hydraulic system and a hydraulic rod, the electrode holder (6) is controlled by an electrode arm hydraulic system (11), and the electrode base frame (1) is provided with a clamping groove. The device takes the purpose of continuous smelting as the main, the energy utilization rate is high, power consumption of slag per ton is low, electrode consumption is low, waste slag, waste water and waste gas pollution does not exist, and the device belongs to an environmentally friendly production industry. In the smelting process, due to continuous smelting and continuous production, efficient and safe electrode adding working is required, the invention provides the method for efficiently and safely adding electrodes for a high titanium slag smelting large-scale direct current seal electric furnace, the electrode adding working is safely and efficiently completed, and an important role in stabilizing the high titanium slag smelting process is played.

Description

technical field [0001] The invention is applicable to the structural technical field of a hollow graphite electrode adding device of a direct-current closed electric arc furnace for high-titanium slag continuous smelting. Background technique [0002] At present, the electric furnaces used in the smelting of high titanium slag mainly include open electric furnaces and semi-closed electric furnaces. The technology is relatively backward and the pollution is serious. The existing closed-type electric furnace smelting titanium slag method is the most advanced method in the world today. This method has simple process, short process, high efficiency, high level of equipment and automation, and the flue gas can be recycled after purification, and has no pollution to the environment. Full-sealed electric furnace smelting includes DC electric arc furnace and AC electric arc furnace. Because of single-electrode smelting, DC electric arc furnace has the characteristics of low smelting...
