Titanium Alloy Extrusion Process Research Technology titanium alloy pump

For the current national economic development and national defense building much-needed domestic production is still

blank titanium profiles of this sunrui titanium alloy pump situation , a variety of technology development through the preparation of the

required titanium profiles, including extrusion , mold design and lubrication technology , mold surface treatment

process , straightening technology , heat treatment technology, combined with TA15, TC4 titanium and other typical ,

walled extruded profiles and L- U profiles ; while developing the necessary pulse profiles forged thin T -and L -

type extrusion billet materials , physical quality approach or reach the international advanced level, to fill the

gaps in titanium alloy profiles .

Titanium Alloy Extrusion Process technology research main content

Because titanium is difficult to deform , extrusion molding is very difficult , we must resolve mold design,

lubrication and profile extrusion Sunrui aerospace investment casting straightening three major problems .
( 1 ) the development of a titanium alloy profile extrusion process, the preparation of a typical alloy profiles 3-4

;
( 2 ) study of lubrication technology, to determine the glass lubricant composition, particle size and lubrication ;
( 3 ) study the extrusion die and mold surface treatment technology, designed and prepared to meet the requirements

of the mold ;
( 4 ) Research Profiles straightening technology, the development of the straightening process parameters ;
( 5 ) Research Profiles heat treatment technology for organizational performance test profiles and fracture analysis

.
