Abstract

The invention relates to a material for an aluminium electrolysis crust breaking chip. The invention is characterized in that the material comprises the following components by weight percent: 50%-70% of tungsten carbide, 5%-10% of titanium carbide, 0.01%-1.0% of carbon, 0.5%-1.0% of silicon, less than 0.05% of phosphorus, less than 0.05% of sulfur, less than 0.05% of nickel and the balance iron. The invention discloses the high hardness crust breaking material; and the material for the crust breaking chip is designed again and uses tungsten carbide as the basic material, thus the service life of the crust breaking chip can be increased, the replacement cycle can be prolonged, the production cost can be reduced and the labor intensity is lowered.

Description

technical field [0001] The invention relates to a material for aluminum electrolytic shelling hammer. Background technique [0002] At present, the material used for electrolytic aluminum shelling hammers is generally forged Q235, cast ZG235-270 steel or other ordinary carbon steel. The steel of these materials has low hardness, low melting point, poor wear resistance, and poor corrosion resistance, so the service life is short, and it needs to be replaced every 3-4 months. Patent 200610050934.1 designed a shelling hammer made of ZG30Cr26Ni5 or ZG30Cr20Ni10 steel in accordance with GB / T8492-1987; 0.2-1.5%, Cr 25.0-35.0%, P and S<0.05%, mixed rare earth 0.075-0.1%) as the shelling hammer, the common feature of these two materials is to increase the Cr content in the hammer , Improve the hardness and melting point of steel. However, the improvement of material wear performance requires not only a high hardness, but also high strength and toughness. At the same time, the...
