Embodiment Construction
[0019] Design a furnace mouth anti-collision protection device for aluminum smelting and heat preservation equipment with longer life and better effect, which has strong operability and practicability.
[0020] Such as Figure 1~3 As shown, the anti-collision frame device at the high-temperature furnace mouth of the aluminum smelting and heat preservation equipment is fixed on the furnace wall steel structure at the furnace door. There are expansion joints between the steel members, and the furnace door frame steel member and the furnace wall steel structure are fixed by bolts; the furnace door frame 1 is welded with rectangular square steel along the length direction and width direction respectively to form a square water-cooled anti-collision frame 2; A cooling water channel is arranged on the square steel, and a water inlet and a water outlet are provided at the end, and cooling water is passed into the cooling water channel.
[0021] The furnace door frame 1 adopts the fo...

The invention provides an anti-collision frame device of aluminum smelting and heat preserving equipment at a high-temperature furnace mouth. A plurality of furnace door frame steel components in partitioned structure forms are fixed on a furnace wall steel structure at a furnace door so as to form a furnace door frame. Rectangular square steel is respectively welded on the furnace door frame along the length direction and the width direction to form a square water-cooling anti-collision frame. The rectangular square steel is provided with a cooling water channel, and the end part of the cooling water channel is provided with a water inlet and a water outlet. The anti-collision frame device has strong operability and practicability and can obviously prolong the service life of the furnacemouth steel components and fire proof materials when in use, thus the anti-collision frame device can be widely applied to various types of aluminum melting furnaces, heat preserving furnaces and mixing furnaces in the industries of aluminum electrolysis and aluminum processing.
Description
technical field [0001] The invention relates to a device for protecting steel members and refractory materials at the furnace door during the charging and slag removal process of an aluminum smelting and holding furnace, in particular to an anti-collision frame device at the high-temperature furnace mouth of the aluminum smelting and holding furnace. Background technique [0002] With the development of technology in the aluminum processing industry, the requirements for charging and slag removal process have increased, and mechanical charging and slag removal have become more and more popular, and then the steel components and refractory materials at the furnace door will be damaged during the charging and slag removal process. Phenomenon is just more and more general, then need a kind of anti-collision device to be used for the steel member and refractory material of protection furnace doorway in order to solve this problem. [0003] At present, most of the smelting furnac...
