Description

Technical Field

[0001] The utility model relates to the technical field of anode assembly, in particular to an iron ladle for anode assembly. Background Art

[0002] Anode assembly is a process of combining the anode aluminum guide rod, steel claw and pre-baked anode carbon block into one. The anode aluminum guide rod and the steel claw are connected by welding, and the steel claw head and the pre-baked anode carbon block are connected together by casting phosphorus pig iron. The iron ladle is a tool used for casting molten iron. The anode carbon block is the "heart" of the electrolytic cell. Each electrolytic cell has a different number of anode carbon blocks according to the cell design (capacity, density, etc.). There are single groups and double groups. The carbon blocks are symmetrically arranged on both sides of the anode horizontal busbar in the electrolytic cell. The guide rod clamp is fixed on the horizontal busbar. The guide rod plays a dual role of transmitting current and hanging the carbon block group.

[0003] When using a ladle for pouring, the molten iron is received in front of the medium frequency furnace and then transported to the casting mold by a crane for pouring. The anode assembly molten iron casting takes 20 minutes per ladle. In order to make the molten iron temperature meet the casting conditions, the molten iron outlet temperature needs to be controlled at 1450°C. However, too high a smelting temperature has a greater impact on the lining of the medium frequency furnace and increases power consumption.

[0004] However, the existing ladles have inner liner in direct contact with the outside world, and heat transfer and loss is too fast. At the same time, the molten iron is directly exposed to the air. Especially in extremely cold weather, the temperature difference between the ladle and the surrounding area is large, which greatly increases the heat loss rate and cannot ensure the temperature for pouring the molten iron. As a result, the molten iron cannot be completely poured into the mold, resulting in insufficient pouring, slag holes in the casting, etc. Utility Model Content

[0005] The utility model aims to provide an iron ladle for anode assembly, so as to solve the problem that the existing iron ladle loses heat too quickly during use, cannot ensure the storage effect of molten iron, causes the molten iron to be unable to be completely poured into the casting, causes insufficient pouring and slag holes in the casting.
