7075 aluminum bar has been widely used in precision machinery because of its good performance. How is 7075 aluminum bar produced?Next 7075 aluminum bar manufacturers to introduce to you, 7075 aluminum bar production process.

1) Casting process:

The ultimate goal is to produce casting process to meet the requirements of rod 7075, and the process to produce rod 7075: melting → casting → homogenization of saw rod → cooling, washing rod → rod entering warehouse.

1. Casting workshop

Smelting technology design process: the furnace charging, melting and mixing time can melt completely, add material, melting, and add the waste, no melting, coating agent, grilled slag and slag agent, stirring, must analyze before sampling, the furnace, and Al - Si (Sl - Cu, Cr additives), Mg ingot to stir, sampling, analysis of furnace after adjustments - composition - refining - steak residue cover and let stand

2, casting

3, saw

4. Aluminum bar homogenization

5. Cool and wash the bar

2) Extrusion process

Extrusion process: before preparation of pressure extrusion → stretching straightening → cutting → finished product into frame opening repair

1. Prepare before squeezing

2, squeezing

3. Stretch and straighten

4. Saw finished products, repair and frame them

Aging process

Solution is cooled after heat treatment to achieve high strength.Subsequent can not be cold processing, to correct straightening process.Then cold drawing is carried out by the stretcher to eliminate the residual internal stress after heat treatment.
