The difference between die cast aluminum and extruded aluminium rods
The standard production process of aluminum extrusion production line of aluminum rod rod can be divided into casting workshop, mold workshop, extrusion workshop (a) / (two), aging workshop, packaging workshop, warehouse, warehouse. The company's total aluminum rod production processes: casting workshop, aluminum rod extrusion workshop warehouse and Aging Workshop and packaging workshop warehouse to warehouse workshop, the following were casting extrusion workshop, workshop, re aging analysis.
The casting process of aluminum bars includes melting, purification, impurity removal, degassing, slag removal and casting process:(1) batching: according to the needs of the production of specific alloy grade, calculated the addition of various alloy ingredients, reasonable collocation of various raw materials(2) melting: the raw material is added into the melting furnace according to the process requirements, and the impurity and gas in the melt can be removed effectively by means of degassing and slag refining(3): casting aluminum liquid in melting casting process under certain conditions, through deep casting system, cooling cast into various specifications of the round casting rod.
(a) the final purpose of casting process casting process is the production to meet the requirements of the aluminum rod, and to produce the aluminum rod, to go through the process of melting, casting, cutting bar, aluminum rod homogenization, cooling, washing bar, aluminum rod into the warehouse.1, melt casting workshop Refining process: charging, melting, melting, stirring, adding waste completely melting, adding waste, melting, and covering agent and deslagging agent, slag, stirring, sampling, furnace analysis, plus Al-Si (Sl-Cu, Cr, Mg, additive) ingot furnace after stirring, sampling, analysis and composition to adjust the refining slag cover, standing for 2, 3, 4, casting material cutting aluminum rod homogenization, cooling, washing 5 rods (two) extrusion extrusion process: preparation, pressure extrusion, stretching and straightening, cutting, trimming and framing finished 1, before 2, extrusion extrusion 3, 4, stretching and straightening cutting products, trimming and framing (three) aging process 6061-T6 state: solid solution heat treatment after cooling to achieve high strength. No cold working status: 6061-T6511 solution heat treatment after cooling to achieve high strength, and then to the school Is the straightening process of.6061-T651 state: solution heat treatment cooling to achieve high strength. Then the tensile cold drawing machine, to eliminate the residual stress after heat treatment, reached after deep processing after deformation to ensure the machining precision of products.
