Titanium Casting Golf Heads because of its high strength, heat resistance, corrosion resistance, widely applied in industry
. Especially in aviation, aerospace , shipbuilding and other industries , mostly used in the manufacture of
titanium alloy casting alloy key components , its performance is good or bad usually determines the level of the product .
Therefore , national research institutions to put a lot of manpower, material and financial resources to
carry out its melting alloys and equipment , forming process research and development , writing papers , and
many thousands of monographs . However, the study of titanium melting process with little , limited studies
have limited studied. Titanium because of its high melting point, chemical activity , thermal properties
between the elements of the big difference , so the smelting process of melt composition and temperature
control is very difficult, and the melt composition and temperature directly determine the quality of
titanium . Therefore , to identify qualitative and quantitative variation of melt composition, temperature
and process parameters , alloy itself between thermal parameters have important practical significance for
guiding titanium melting , smelting practice for other alloys also have important reference value.
In recent years, with the introduction of National Laboratory " metal precision thermal processing ," a
water-cooled copper crucible induction melting furnace , our group has invested major forces units alloy
water-cooled copper crucible induction melting (IsM) thermodynamics and kinetics , and achieved some
results. Now be summarized in order to communicate with readers , and jointly promote the development of
titanium industry.
The book is a national "Ninth Five " key books . This paper focuses on titanium melt composition,
temperature control of the main line , in theory, more in-depth analysis of the system ISM smelting process
titanium alloy melt composition influence factors and the role of law in temperature, and several commonly
used titanium alloy analyzed. The book is divided into eight chapters , of which the first chapter
introduces the features and titanium smelting technology ; second, third and sixth chapters are discussed
the impact of volatile behavior of titanium alloy melt composition of alloying elements , interstitial
elements in titanium melting body dissolved in class skull formation mechanism ; fourth and fifth chapters
ISM titanium smelting process gives the temperature field numerical simulation model and process parameter
optimization design ; Chapter VII of the smelting process ISM exists a theoretical risk analysis ; Chapter
VIII describes some examples of titanium smelting .

the titanium alloy film surface of the tube
When the temperature does not exceed 540 ℃ , the
titanium alloy film surface of the tube does not significantly thickened , however, the heat treatment at higher temperature (760 ℃ above ) , the oxidation rate is rapidly increased, and the oxygen expansion inside material to form a diffusion layer - contaminated layers. Oxygen contamination layer has a high
titanium sheets leads to brittle parts of the surface cracks and damage. Removing contaminated layers of oxygen with mechanical processing methods ( such as room cut , sandblasted , etc. ) , or pickling, chemical milling and other chemical methods , in the heat treatment , the heating time should be guaranteed under the premise of the heat treatment is shortened as much as possible meteorite , but also in performed in a vacuum furnace or an inert gas (argon , nitrogen, etc. ) furnace . Application of appropriate Xu Min can avoid or reduce contamination titanium tube furnace parts heating in air generated .
Titanium pump is removed by heat treatment method other substances
When excessive hydrogen content of titanium pump, become brittle leaving notched impact toughness and tensile strength of a sharp decline in the general provisions of the hydrogen content of titanium bars shall not exceed 0.015% . To reduce the amount of hydrogen absorption , parts should be removed prior to heat treatment fingerprints, rolling mill mark , grease and other residue , no vapor heat treatment furnace atmosphere . If the hydrogen content of
titanium casting process tube exceeds the allowable value , must be removed by vacuum annealing . Dehydrogenase is generally vacuum annealing at 538-760 ℃, maintained under a pressure lower than 0.066Pa 2-4h.

How the development of titanium tube casting process titanium sponge
At present, the domestic technology of cast titanium tubes have carried out some research and development work has evolved from the initial simple
graphite casting process to the coexistence of multiple process Sunrui titanium golf clubs steps, their level has been greatly improved. Casting titanium tube is quite extensive,
almost all already known to use cast molding method. Recently, more widely used in the production process is machined graphite, graphite tamping
precision investment casting and ceramic shell mold casting process.
Due to simplify the learning activity of titanium alloy tube has, making it the casting process is different from iron-and nickel-based alloy, and has many
unique features, which is mainly manifested in the sunrui Titanium Golf Club Heads choice of mold material. Cast titanium tube holding type material used must have a high chemical
stability, high thermal shock resistance, low moisture absorption capacity and low thermal resistance, complete with mold material at these performance
requirements are still being explored.

Titanium tube heat transfer efficiency to beat rivals titanium pump
From the viewpoint of heat transfer efficiency, we find that the titanium alloy pipes with other tubing
(e.g., copper-nickel alloy) match. sunrui aerospace investment castings High strength titanium and high impact resistance allowable turbidity of
seawater with high flow rates and titanium alloys have a high temperature corrosion resistance, titanium-
nickel alloy than copper heat exchanger 60 a weight reduction of 70%, the their overall heat transfer
efficiency is roughly the same.
Due to the longer life of the sunrui titanium bicycle frame titanium tube structure to offset one-time investment, in terms of
economic efficiency is also something else. And because of the speed for the entire period in the life of
the tube can reduce downtime, thus also receive an additional character. With the growth and expansion of
the use of titanium production, the cost and availability of titanium improved. Titanium also with 317L
stainless steel, Monel alloy 400 and Sunrui Titanium Casting Golf Heads Hastelloy C-276 to compete. It is predicted that in the middle with
seawater cooled heat exchangers, finned whole rolled titanium tube will completely replace copper-based
alloy tube.
