Description
One, technical field
The utility model relates to a kind of integrated vertical hydrogenation dehydrogenation furnace, and it belongs to the equipment in the production of titanium or titanium alloy powder.
Two, background technology
The hydrogen solid solution forms clearance-type solid solution in titanium, and the course of dissolution of the solid solution of hydrogen in titanium is reversible.
The phasor of titanium and hydrogen, titanium can be inhaled hydrogen in a large number.319 ℃ eutectoid occurs, begin vigorous reaction at 350 ℃ of titaniums and hydrogen, inhale H-H reaction and can be decided to be 350～680 ℃.Higher temperature titantium hydride will decompose, and under an atmospheric pressure, 683 ℃ is that decomposition reaction is the top.The equilibrium partial pressure of figure three hydrogen and the relation of temperature, when 500 ° of K, the hydrogen dividing potential drop is 0.344Pa, at 600 ° of K, the hydrogen dividing potential drop is 52.92Pa, during 623.15 ° of K, hydrogen dividing potential drop 136.4Pa, during 1000 ° of K, the hydrogen dividing potential drop significantly is elevated to 2.025 * 10
+ 6The dividing potential drop of hydrogen when reacting the reaction temperature of reversible direction when depending on hydrogenation with reaction.When temperature dividing potential drop low and hydrogen is higher, show as the suction hydrogen process of titanium; When the dividing potential drop of temperature rising and hydrogen constantly reduces, show as certain embodiments.Titantium hydride is very crisp, is easy to be broken into powder.Making titanium valve is exactly this character of utilizing titanium.
---hydrogenation---is pulverized---screening---dehydrogenation---pulverizing---screening---check---weighing---packing to process route: raw material
Raw material: can be the titanium bits, also can be titanium sponge.Because oxygen content is higher in the titanium bits, contains some other impurity, the class of the titanium valve of manufacturing is lower, and total Ti content is 95%～98%.Need total Ti content more than 99%, oxygen content is at 0.3% titanium valve, and raw material should be titanium sponge.
The operation of hydrogenation is carried out in hydrogenation furnace.The type of furnace of original technology is horizontal, and its type of furnace during with dehydrogenation is the same, and just container is different.Container is the groove shape during hydrogenation, is square plate during dehydrogenation, 4～5 compositions.Titanium after the hydrogenation is a titantium hydride.The very crisp easy pulverizing of titantium hydride.Hydride powder after the pulverizing sieves, and selects the granularity that needs.These hydride powders charging tray of packing into, the thickness of material is 20～30 millimeters, the blocked up effusion that is unfavorable for gas.Charging tray is put into dehydrogenation furnace, carries out dehydrogenation.
The key equipment of titanium valve production is hydrogenation furnace and dehydrogenation furnace.These two kinds of type of furnaces are the same.In the seventies in last century, titanium valve production gets into commercial production by the laboratory.The comprehensive output of China reaches 2000 tons at present.But it is not progressive on the type of furnace of hydrogenation, dehydrogenation.Existing equipment mainly contains following defective:
(1) batch is few, and production efficiency is low; Usually diameter 400 length 1200. of body of heater are because when cooling, body of heater withdraws from heating furnace, and it is cantilever-shaped that body of heater is, body of heater can not do more greatly, longer.
(2) quality of product is low.Equipment is only found time with mechanical pump, and vacuum is at the order of magnitude of Pa, and in hydrogenation stage, residual air is more, causes product oxygenation; Vacuum is low when dehydrogenation, must cause dehydrogenation insufficient, has increased the hydrogen content of goods.In the seventies in last century.Someone thinks that hydrogen content is higher favourable to sintering, and high hydrogen content is not a problem.The purposes of titanium valve enlarges in recent years, and some fields propose very high requirement to hydrogen content, at aspects such as field of powder metallurgy, little forming techniques, requires the hydrogen content of powder, oxygen content all low, and original equipment can not be satisfied the demand.
(3) uniform temperature of body of heater is bad; Heating furnace is district power supply, a thermocouple control.Often, the temperature of the inside is higher, and outer surface temperature is lower, and the color inside and outside of titanium valve is inconsistent.
(4) exit in a large number at the initial period of finding time to begin with dehydrogenation, some dust and air-flow move together, get into mechanical pump.Dust has damage to mechanical pump.Usually on the pipeline of body of heater to mechanical pump, add a filter (stainless steel pompon or oil sealing), in fact this increase vapour lock, reduces the efficient of mechanical pump.
