What's the difference between cast aluminum bars and extruded aluminum bars?

What's the difference between cast aluminum bars and extruded aluminum bars?

Answer:

1: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 stirring, sampling, analysis, composition adjustment, furnace refining drossing cover, standing for 2, 3, saw material casting4, aluminum rod homogenizing 5, cooling and washing rod (two) extrusion process extrusion process flow:The pressure before, extrusion, stretching and straightening, cutting, trimming and framing finished 1, before 2, extrusion extrusion3 、 stretch straightening4, finished cutting, trimming and framing (three) aging process
Production process of standard extruded aluminium barsThe aluminum bar production line can be divided into casting workshop, mould workshop, extruding workshop (1) / (two), aging workshop and packing workshopWarehouse and aluminium bar warehouse. The company's general production process is: casting workshop, aluminium bar warehouse, extrusion workshop, aging workshop, packingWarehouse to finished warehouseThe following analysis focuses on the casting workshop, extrusion workshop and Aging Workshop. (1) the casting processThe final purpose of 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 casting workshop process of smelting process, uniform cooling, washing bar, aluminum rod into the warehouse,.
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: molten aluminum liquid, in a certain casting process conditions, through the deep casting system, cooling casting into various specifications of the round casting rod
