Description
Technical Field
The invention belongs to a waste metal aluminum recycling technology, and particularly relates to a preparation method and an application method of an aluminum briquetting deoxidizer.
Background
In the metal smelting industry such as steel making, a large amount of various charging additives (for example, the using amount of aluminum and calcium is about 0.2-8 kg/ton steel) are used for deoxidizing and denitriding the smelting metal and improving the performance of the smelting metal. The main products of the aluminium-based deoxidizer for steel making at present comprise aluminium blocks, aluminium iron and other materials, and the main raw materials of the deoxidizer are metal aluminium ingots generated by aluminium oxide electrolysis or aluminium ingots obtained by melting and casting secondary aluminium in a reverberatory furnace, and then the deoxidizer is melted and cast in an intermediate frequency furnace according to a certain proportion with waste steel. Both the electrolytic process of metal aluminum ingot, the melting process of secondary aluminum in a reverberatory furnace and the smelting and casting process of an intermediate frequency furnace need to consume a large amount of electric energy and fuel, so that the energy consumption cost is high.
The recovered waste metal materials are used for preparing the furnace charge additive, a process method of heating and melting metals and then cutting into blocks for molding is generally adopted, the energy consumption of molten metal casting molding in the manufacturing process is large, a large amount of carbon dioxide is discharged due to fuel consumption in the heating and melting process, the environmental pollution is large, and the production cost is high.
CN201210432365.2 discloses a method for recycling waste aluminum and waste zip-top cans in a green circulating and guaranteed level, which comprises the following steps: the aluminum alloy for producing the waste pop-top can is obtained through the working procedures of crushing, magnetic separation iron removal, paint removal, smelting, component adjustment, filtration and casting. Wherein, pretreatment paint removal: the method comprises the steps of enabling waste pop-top can fragments to enter a paint removing kiln for paint removal, enabling a paint layer to be carbonized, enabling carbon particles to fall off completely through special vibration equipment, enabling gas and the carbon particles discharged from a rotary paint removing kiln to be introduced into a high-temperature furnace for secondary combustion, enabling one-stage combustion to be in an anoxic reduction region, controlling the temperature to be about 850 ℃, enabling smoke to continue to be sent into a secondary combustion chamber for thorough oxidative decomposition, and enabling the temperature in the secondary combustion chamber to be higher, wherein the temperature is usually higher than 1000 ℃. Smelting: a heat accumulating type double-chamber reverberatory furnace is adopted, after an aluminum sheet after depainting is packed, molten aluminum liquid is pressed into an outer chamber for melting, the molten aluminum liquid is heated by the flame of the reverberatory furnace in an inner chamber, and the molten aluminum liquid in the inner chamber and the outer chamber circulates by virtue of a ceramic pump; the temperature of the aluminum liquid in the outer chamber is 700-850 ℃, and the temperature of the aluminum liquid in the inner chamber is 850-950 ℃.
CN202011449896.3 discloses an aluminum-iron deoxidizer for smelting and a preparation method thereof, wherein the aluminum-iron deoxidizer for smelting comprises the following components: 35 to 75 percent of aluminum, 23 to 63 percent of iron and 1.0 to 3.5 percent of binding agent. The preparation method of the aluminum-iron deoxidizer for smelting comprises the following steps: carrying out impurity removal, preselection and crushing treatment on the waste aluminum foil light thin material; roasting the crushed waste aluminum foil light and thin material to remove surface attachments, and then granulating to obtain aluminum particles; weighing aluminum particles, iron and a binding agent, uniformly mixing to obtain a mixture, carrying out cold press molding on the mixture, and curing to obtain the high-strength aluminum-iron deoxidizer. Wherein cold press forming the blend comprises: feeding the mixture into a briquetting machine for primary extrusion forming to obtain a primary cold-pressed block, crushing the primary cold-pressed block, returning the crushed primary cold-pressed block to the briquetting machine for secondary extrusion forming to obtain the high-strength cold-pressed block.
In the existing method for recycling the waste easy open can, paint removal is realized by carbonizing organic matters in a fuel heating roasting and smelting mode; in the molding and smelting process, fuel is used for heating to melt and mold the aluminum sheet. Because the aluminum sheet formed after the waste aluminum and waste pop-top cans are crushed belongs to a solid with large sheet surface area, the aluminum is an active metal, and is subjected to paint removal and forming in a roasting and smelting mode under the aerobic condition, the aluminum sheet can be inevitably oxidized into Al 2 O 3 The burning loss is serious, the recovery rate of the waste aluminum and the waste pop-top can is greatly reduced, and the recovery cost is improved. Meanwhile, in the paint removing and smelting processes, a large amount of fuel is inevitably consumed additionally, so that the energy consumption cost is high, the carbon dioxide emission is increased, the solid hazardous waste emission such as aluminum ash is increased, and the environmental pollution is caused.
In the cold press molding process, aluminum particles and iron are bonded together by a bonding agent, wherein the bonding agent is a mixture of a high molecular bonding agent and a liquid metal bonding agent. Because the time is required for the bonding agent to perform the bonding action, the cold-pressed block needs to be shaped through maintenance. Because the binding agent is a polymer binding agent, which is equivalent to re-injecting the carbonaceous material into the aluminum material, the roasting decarburization effect at the beginning of the process is greatly reduced, even the decarburization effect is completely counteracted, and the use effect of the aluminum-iron deoxidizer is seriously influenced.
Among the above-mentioned equipment, no matter roasting kiln, depainting kiln all are firing equipment, and firing equipment need keep away from material former, and the decarbonization material needs frequently carry former, causes firing equipment, former can not use same production line, and it is big not only to occupy the place, is unfavorable for realizing the butt joint from top to bottom of production node moreover, is unfavorable for realizing automated production.
