Titanium tubes are similar to other metals. The shrinkage behavior of titanium tubes during casting also undergoes a change from the liquid state to solid state to solid-state. This shrinkage behavior is usually divided into body shrinkage and linear shrinkage. The body shrinkage reflects the change in the entire volume of the titanium exhaust tube during the casting process. Since the total body shrinkage is equal to the volume of the concentrated shrinkage holes of the casting plus the volume of shrinkage, the solidification shrinkage behavior of the alloy casting process is related to the body shrinkage of the alloy The characteristics of shrinkage and shrinkage defects of drill alloys are determined, which are of great significance for understanding the formation of shrinkage and shrinkage defects of Grade 23 Titanium Tube.
The important factors that affect the solidification and shrinkage of titanium tubes include alloy elements, mold materials, and mold structures. Since alloying elements affect the crystallization temperature interval of the titanium tube, just as it affects the fluidity, the solidification shrinkage of the titanium tube first depends on the characteristics of the added alloying element, that is, the crystallization temperature formed between the titanium and the alloying element The size of the interval is related. The eutectic Titanium Coil Tube with a narrow crystallization temperature interval has good fluidity and is easy to form concentrated shrinkage pores, while the titanium tube with wide crystallization temperature interval is poor in fluidity and easy to form dispersed shrinkage pores, ie shrinkage.
Because titanium tubes have a series of good physical properties, as an excellent structural material, it can compete with stainless steel and nickel alloys for the scope of application: in many sectors of the national economy, the use of titanium tubes has increased product life and improved The reliability and productivity of the equipment have accelerated the process and improved working conditions, all of which have achieved significant economic benefits.
