titanium foundry casting titanium and titanium alloy pressure

Good melting of titanium with a certain degree of superheat liquid by turning the crucible, casting by pouring cup was sent to the room, under the effect of pressure die-casting rod, casting type liquid titanium foundry into the cavity from the casting room, die casting good at casting type inner packing, cooling, and then removed. To eliminate casting surface may produce cold traps, flow marks or other defects due to cast, especially the thin edge. Die-casting should be preceded by the type of warm-up. Arc melting is used as a heating source, in addition, a vacuum aerospace titanium may also be used in induction heating, electron beam heating, or the suspension smelting. Heat-resistant steel casting-type material used in severe erosion by liquid titanium foundry molybdenum or special places may be inlaid graphite block. Casting chamber die casting machine uses heat-resistant alloy. Pressing the piston head with a molybdenum alloy or heat-resistant alloy. Type casting surface roughness should not be less than Ra≈0.6μm, otherwise, it should affect the surface quality precision castings. To improve the life of the mold and die casting part, a lubricant may be sprayed on their work surface.

Titanium sponge and impact on the future development of the market

In a recent meeting of experts of titanium and titanium alloy Thirteenth National Symposium confirmed: From the perspective of cities across the country , in addition to outside Luoyang , China does not have a region or city has a complete industrial chain of titanium , however Luoyang City can titanium sponge production of titanium ingots , but Titanium castings also can produce titanium sponge into titanium mill until the production of titanium equipment. China is currently the only city which has a complete industrial chain of titanium - " Titanium City ."It is understood that , after 40 years of development, China has become after the United States , Japan, Russia and the fourth has a complete industrial system titanium sponge titanium country . Experts, a complete industrial chain of titanium sponge , the main components products are: titanium sponge ( base material ) - titanium cast ( casting ) , semi-finished products , titanium processing material ( sheet, strip, tube , rod ) - titanium parts and titanium equipment manufacture. Although the country as a whole , China's titanium industry with complete system , but on a city or a region, titanium foundry currently has only met the requirement of Luoyang whole industry chain.Titanium sponge as materials research and application of marine focal point, located in Luoyang, China Shipbuilding Industry Corporation Institute is one of the seven two five research institutes to carry out a few handful of domestic titanium systems research , applied research in titanium areas represent the national level.

Use titanium sponge instead of stainless steel high pressure

 As another example, the SR - 71 high speed scout (flight Mach number is 3, altitude 26212 meters), titanium accounted for 93% of the plane structure weight, so-called "titanium sponge" aircraft. When aeroengine in esteem than increased from 4 to 6 to 8 ~ 10, compressor outlet temperature accordingly increased to 500 from 200 ~ 300 ° C to 600 ° C, originally made of aluminium low-pressure compressor disk and blade must use titanium alloy material, or use titanium sponge instead of stainless steel high pressure compressor disk and blade, in order to reduce the structure weight. In the 70 s, the dosage of titanium alloy in the aircraft engine generally accounts for 20% ~ 30% of total weight structure, mainly used in the manufacture of compressor parts, such as forging of titanium fan, compressor disk and blade, titanium compressor casing, intermediate Titanium casting, bearing housing, etc. Spacecraft, which make use of the specific strength of titanium alloy, corrosion resistance and low temperature resistance to manufacture all kinds of pressure vessel, fuel tank, fasteners, instrument strap, architecture and rocket shell. Artificial earth satellite, the lunar module, manned spacecraft and space shuttle USES titanium alloy plate weldments. Titanium‬ precision castings,‪#‎Titanium_castings‬ Sunrui‪ Titanium‬ precision castings,‪Titanium castings‬  www.sunrui-titanium.com

Future of titanium sponge powder

Strategic metals - titanium (Titanium): element symbol Ti, atomic number 22, atomic weight 47.88, located on the 4th cycle ⅣB family in the periodic table. Titanium is one of the most widely distributed crustal abundance of elements in high (6320 × 10-6), accounting for 0.61% by weight of the crust columns ranked 9; resources are second only to iron and titanium sponge, aluminum, magnesium and column ranks section 4, is an important raw material preparation slag, synthetic rutile, titanium dioxide, titanium sponge, titanium metal and titanium, welding rod coatings. Because titanium silvery white, with a high melting point (1727 ℃), light weight (4.5), high mechanical strength (5), low temperature (ultra low temperature resistivity is almost zero), abrasion resistance, good plasticity titanium wire (can thin-walled use), easy to oxidation, reduction and other characteristics; titanium oxide - titanium dioxide (titanium dioxide), with non-toxic, good physical and chemical stability (after 1000 ℃ calcination does not melt at any acid and alkali) , the refractive index is high (2.55 to 2.70), as well as a strong whiteness, color strength (1150 to 1650), hiding (40 ~ 50g / m2), temperature resistance, anti-chalking and other characteristics, is called "paint the king. "

Step titanium supplier screening process

Alpha alloy and usually alloy annealing temperature to beta phase transition point below ; Solid solution and aging treatment from high temperature rapid cooling, to get marten site alpha 'phase and meta stable beta phase, and then in aerospace investment castings the temperature range of the thermal insulation makes the meta stable phase decomposition, alpha or compounds, such as small dispersed second phase particles reach the purpose of the alloy strengthening. Usually alloy quenching and beta phase transition point below, metastable beta alloy quenching inbeta phase transition point above. Aging treatment temperature .Solid solution treatment and aging: the purpose is to increase its strength, alpha titanium alloy and stable beta titanium alloy cannot be strengthening Titanium castings treatment, only for annealing in the production. Alpha + beta, and contain a small amount of metastable beta of alpha titanium alloy titanium alloy can make through solid solution treatment and aging alloy further intensified.Teach candidates in this election ore, the resistance of various minerals larger difference Fortunately, you can use a string of iron ore of high conductivity characteristics, the electric field in the corona effectively exclude gangue minerals and high-grade titanium supplier concentrates . The heavier selected indicators, the re-election process can titanium ingot price only admire iron and titanium supplier augite, chief of the purpose of throwing stones and other layers. Diamond production process for the election to re-elect a spiral of weak magnetic flotation a sweeping election a dehydration grading an electrical election process. It is divided into two parts, rent selection and selection. Rougher including the screening screening, hydraulic classification, re-election, flotation, weak magnetic separation, dehydration and filtration processes; featured include drying grouping, electrostatic separation, concentrate and packaging processes.

​The poor thermal stability should not be used at high temperature

   The poor thermal stability should not be used at high temperature.It is duplex alloy, with good comprehensive performance, organizations have good stability, good toughness, plasticity and high temperature deformation resistance, titanium ingot price thermal pressure processing can be well, to hardening, aging makes the alloy strengthening. The strength of the heat treatment after about higher than that of annealing state; High temperature and high strength, can under the temperature to work for a long time, its thermal stability is inferior to alpha titanium alloy.Three types of titanium alloy is the most commonly used in alpha and alpha + beta titanium alloy titanium alloy; Alpha titanium alloy cutting processability, best alpha + p times titanium alloy, the beta titanium alloy is the worst. Alpha titanium alloy, code-named TA, beta, titanium alloy, code-named TB, alpha beta, titanium alloy, code-named TC.Titanium alloy can be divided according to the use, high strength alloy, heat-resistant alloy corrosion resistant alloy, titanium, molybdenum, titanium and palladium alloy etc.), low-temperature alloy and special function (titanium - hydrogen storage materials of iron and nickel titanium memory alloy), etc. Typical alloy composition and properties are shown in table.
