Background technology
Traditional vacuum smelting furnace is main scavenging pump by lobe pump and oil diffusion pump, has complex structure, pumping efficiency is low and energy consumption is high shortcoming.In addition, in the time that superalloy is poured into a mould, for preventing ingot casting depanning difficulty, conventionally use and smelt heelpiece at mold bottom, prevent ingot casting and mould adhesion, play the effect of prevention depanning difficulty.But heelpiece upper surface and ingot casting bottom are prone to adhesion phenomenon and cause depanning difficulty, in addition, because molten steel distributes rapidly and causes ingot casting knot crackle at the heat of bottom, in forging process, concentrate and easily cause the quality problems such as cracking because of ingot casting bottom stress.
Summary of the invention
The purpose of this utility model is to provide a kind of titanium manganese alloy smelting apparatus, and smelting furnace is simple in structure, reduced the time of bleeding and saved air exhaust energy consumption; And solve stress in depanning difficulty, bottom crack of ingot and forging process and concentrated the quality problems such as the ingot casting end face cracking that causes.
Titanium manganese alloy smelting apparatus described in the utility model, comprise smelting furnace, vacuum pump, molecular drag pump, air distributing device, casting mold, described smelting furnace top is provided with feeding device, feeding device is connected with the charging opening at smelting furnace top by pipeline, vacuum pump, molecular drag pump, air distributing device is connected with smelting furnace respectively by pipeline, vacuum pump, molecular drag pump, on pipeline between air distributing device and smelting furnace, be respectively equipped with valve, smelting furnace one side arranges vacuumometer, heating unit, smelting furnace two bottom sides is provided with support, smelting furnace arranges discharge port in the middle of bottom, the corresponding discharge port in smelting furnace below arranges the casting mold of opening upwards, casting mold inner chamber bottom sets gradually ingot casting heelpiece and insulation heelpiece from bottom to top, insulation heelpiece middle part is provided with through hole, insulation heelpiece upper surface is horizontal by the circular arc of 80 degree～100 degree.
Wherein: insulation heelpiece adopts lagging material to make, and considers physics and chemistry, mechanical property, and insulation heelpiece upper surface and horizontal plane are preferably the circular arc of 96 degree.
Wherein, molecular drag pump is that the rotor of gas molecule and high-speed rotation collides and obtains momentum, is sent to a kind of momentum transfer of outlet, replaces lobe pump and the diffusion pump of traditional smelting furnace, and mainly adopts coordinating of molecular drag pump and vacuum pump.
When use, first titanium is put into smelting furnace, open vacuum pump, smelting furnace is carried out to step-down, and pressure drop, to the operating pressure of molecular drag pump, is to be generally reduced to 100-300Pa, vacuum pump cuts out, and open molecular drag pump, smelting furnace is transformed into molecular drag pump and bleeds; In the time that the pressure drop of smelting furnace is low to moderate the pressure of suitable pre-appearance, be generally 1-10pa, start heating unit, titanium is carried out to fritting, when fritting, vacuumometer is for detection of the vacuum tightness in smelting furnace.After fritting finishes; smelting furnace continues to be bled by molecular drag pump; reach smelting intensity; conventionally be set to 1-2Pa, stop molecular drag pump, smelting furnace injects shielding gas by air distributing device; shielding gas is generally argon gas; heating unit adopts traditional technology to carry out melting afterwards, and then manganese enters smelting furnace by feeding device through opening for feed, carries out melting.After melting, open discharge port, melted alloy enters in the die body of ingot casting casting mold through discharge port, insulation heelpiece upper surface is horizontal by the circular arc of 80 degree～100 degree, make ingot casting in casting process, there will not be the bottom crack of ingot causing because of distributing rapidly of bottom molten steel heat and in forging process, there will not be because of bottom stress to concentrate and cause cracking phenomena, effectively improved and ingot quality.
In sum, the utlity model has following advantage:
(1) the utility model simple in structure, reduced the time of bleeding, and saved air exhaust energy consumption.
(2) melted alloy enters rapidly in the die body of ingot casting casting mold through discharge port, prevents that alloy is oxidized.
(3) insulation heelpiece of the present utility model upper surface becomes globoidal structure from two dimensional structure, make ingot casting in casting process, there will not be the bottom crack of ingot causing because of distributing rapidly of bottom molten steel heat and in forging process, there will not be because of bottom stress to concentrate and cause cracking phenomena, effectively improved and ingot quality.
