Problems solved by technology

During the use of existing anode steel claws, the part above the joint between the claw head and the phosphorus iron ring in the carbon electrode is easily corroded and oxidized, resulting in bending and thinning of the claw head, increasing the voltage drop and power loss, so it must be regularly To replace the claw head, the general replacement cycle is 1 year, and the production and maintenance costs are high

Abstract

The invention discloses a production method of a lost foam casting anode steel claw head. The production method comprises the following steps of: preparing molten steel, wherein the molten steel comprises the following components in proportion: 3-6% of chromium, 0.6-1.2% of manganese, 0.45-0.8% of carbon, 0.4-0.8% of silicon, 0.2-0.3% of molybdenum, less than 0.04% of Sulphur, less than 0.04% of phosphorus and the balance of Fe; and pouring the molten steel into an anode steel claw head lost module by adoption of a lost foam casting process, so as to obtain the lost foam casting anode steel claw head. The invention furthermore discloses the anode steel claw head lost module. The anode steel claw head is good in comprehensive quality and long in service, so that the production and maintenance cost can be remarkably reduced.

Description

technical field [0001] The invention relates to the field of anode steel claw preparation. More specifically, the present invention relates to a method of lost foam casting anodic steel claw head and the lost mold group of anodic steel claw head. Background technique [0002] The era of low-carbon economy is the need of today's scientific and technological progress and development, and energy saving and consumption reduction is also the need of today's national policy and sustainable economic development. The electrolytic aluminum anode steel claw is the connection component between the anode carbon block on the electrolytic cell and the busbar wire. It loads a large current during the aluminum electrolysis process. It is one of the most important consumable parts for electrolytic aluminum production enterprises. The quality of the steel claw is good. Bad directly affects production efficiency and production cost. During the use of existing anode steel claws, the part abov...
