Embodiment Construction

[0034] A composite new material mold bottom plate, using high-quality scrap steel, ferrosilicon, ferromanganese, ferromolybdenum, micro-chromium and other raw materials to configure alloys, put some of these raw materials into an induction furnace for melting, the temperature is 1600 ° C, when the molten steel is clear , test the molten steel composition, if the composition is unreasonable, then mix according to the target alloy composition and add the corresponding alloy and scrap steel, when the molten steel composition is appropriate, add cullet, on the premise that the alloy can also be poured smoothly, make the alloy liquid The slag and gas have enough time to float up, remove the gas and inclusions in the alloy liquid, and add rare earth into the ladle, keep a certain calm time, pour in the sand mold made, clean, anneal, finish, press Figure processing, you can get a qualified mold bottom plate.

Abstract

The invention aims at providing a mold bottom plate made of a novel composite material, and provides a mold bottom plate made of cast steel. The mold bottom plate is made through the steps that after steel is melted, an appropriate amount of chromium, molybdenum and rare earth is added into molten liquid, and then mold casting is performed. The service life of the mold bottom plate reaches up to about 80 times and is doubled compared with an existing spherulitic graphite mold bottom plate. The novel composite material is not only used for the mold bottom plate, but also is suitable for products such as a copper-sulfur bag and an electric stone bowl.

Description

technical field [0001] The invention relates to the field of smelting, in particular to a composite new material mold bottom plate. Background technique [0002] The bottom plate of the mold is the master mold for the production of the anode plate in the copper smelter. Based on this master mold, the manufacturer uses the copper water produced to make the model of the anode plate. Based on this model, the anode plate is produced, and then the anode plate enters the electrolysis workshop for electrolysis Assembly line operation, so the quality of the base plate directly determines the quality and accuracy of subsequent operations. [0003] When producing the anode plate, the bottom plate of the mold, the surrounding side plates and the cover plate are assembled into one body, and the copper water is directly injected to form the model of the anode plate. Tons, pouring time is about 30 seconds, holding time is about two hours, then remove the side plate and cover plate, so ...
