Musoro: Kukosha kweVacuum Induction Furnaces muSmelting Alloys

Pakunyungudutsa alloys, maitiro acho anoda kunyatsorongeka uye kudzora kuti hunhu hwaunoda hubudirire. Chinhu chakakosha pakuita izvi kushandisa vacuum induction furnace. Aya maovheni anoita basa rakakosha mukunyungudutsa alloys dzakasiyana-siyana, imwe neimwe iine zvinodiwa zvayo. Mublog rino, tichaongorora mhando dzakasiyana dzealloys dzinoda kunyungudutswa muchitofu che induction che vacuumuye zvikonzero zvekudiwa kwazvo.

Imwe yemhando dzesimbi dzinonyungudutswa zvakanyanya uchishandisa vacuum induction furnace isimbi isingatsvedzeri. Simbi isingatsvedzeri imhando yesimbi inoshandiswa zvakasiyana-siyana, kubva kumidziyo yekicheni kusvika kumichina yeindasitiri. Maitiro ekunyungudutswa kwesimbi isingatsvedzeri anoda kudzorwa kwakanyatsojeka kwechimiro chesimbi iyi uye kubviswa kwetsvina yakaita sekabhoni nesarufa. Maovheni emuchina wevacuum anopa nzvimbo yakanaka yekunyungudutswa kwesimbi isingatsvedzeri nekuti anogona kudzora tembiricha nemhepo panguva yekunyungudutswa.

Imwe mhando yakakosha yakanyungudutswa uchishandisa vacuum induction furnace iplatinum-rhodium alloy. Platinum-rhodium alloy inozivikanwa nehukuru hwayo hwepamusoro uye kuramba kwayo ngura, zvichiita kuti ive chinhu chakakosha kumaindasitiri akadai sendege nemidziyo yekurapa. Kunyungudutsa platinum-rhodium alloy kunoda kuchena kwakanyanya nekuti kunyangwe tsvina diki inogona kukanganisa zvakanyanya hunhu hwayo. Mafurnace evacuum induction anokwanisa kugadzira nzvimbo yakachena inodiwa kuti anyungudutse platinum-rhodium alloy, zvichiita kuti ive yakakosha pakugadzira iyi mhando inokosha.

Muindasitiri yezvemuchadenga, ma superalloy anodiwa zvakanyanya nekuda kwekugona kwawo kutsungirira tembiricha yakanyanya uye kushushikana kwemakanika. Ma alloy aya anoshandiswa mukugadzira ma turbine blades, zvikamu zveinjini nezvimwe zvinhu zvakakosha zvendege nendege. Kunyungudutsa ma alloy anodziya zvakanyanya akadai seInconel neHastelloy kunoda kudzora kwakaringana maitiro ekunyungudutsa nekusimba uye kubviswa kwetsvina. Maovheni evacuum induction anopa mamiriro anodiwa ekunyungudutsa ma alloy anodziya zvakanyanya kuti agadzire zvinhu zvepamusoro-soro, zvinoshanda zvakanyanya zvekushandisa mundege.

Muindasitiri yemotokari, aruminiyamu inoshandiswa zvakanyanya nekuda kwehunhu hwayo hwakareruka uye hunodzivirira ngura. Kunyungudutsa aruminiyamu kunoda kudzora nekungwarira maitiro ekunyungudutsa nekukanda kuitira kuti hunhu hwemakanika huvepo. Mafurniture evacuum induction anopa kudzora tembiricha chaiyo uye mhepo inodiwa kuti inyungudise aruminiyamu, izvo zvakakosha pakugadzira zvinhu zvemotokari zvemhando yepamusoro.

Muindasitiri yezvekurapa, zvinhu zvinoenderana nehupenyu zvakaita setitanium alloys uye cobalt-chromium alloys zvinoshandiswa mukugadzira zvinhu zvinoiswa mumidziyo yekurapa. Kunyungudutsa zvinhu izvi kunoda kuchena kwakanyanya uye kudzora kuumbwa kwazvo kuti zvive nechokwadi chekuti zvinosangana nezvinodiwa zvakasimba zvekugona kuenderana nehupenyu uye hunhu hwemakanika. Zvitofu zvinopinza vacuum zvinopa mamiriro anodiwa ekunyungudutsa zvinhu zvinoenderana nehupenyu, zvichiita kuti zvive zvakakosha pakugadzira zvinhu zvekurapa.

Muindasitiri yezvemagetsi, ma alloy emhangura anoshandiswa nekuda kwekufambisa magetsi uye hunhu hwekupisa. Kunyungudutsa ma alloy emhangura kunoda kudzora kwakanyatsojeka kwekuumbwa kwawo uye kubviswa kwetsvina kuitira kuti hunhu hwemagetsi nehwemakanika hubudirire. Maovheni evacuum induction anopa nzvimbo yakanaka yekunyungudutsa ma alloy emhangura kuti agadzire zvinhu zvemhando yepamusoro zvekushandisa zvemagetsi.

Muchidimbu, magumbeze evacuum induction anoita basa guru mukunyungudutsa ma alloy akasiyana-siyana, rimwe nerimwe riine zvinodiwa zvaro zvakasiyana. Kubva kusimbi isina ngura kusvika ku titanium, kubva ku alloy dzinopisa zvakanyanya kusvika ku alloy dzearuminiyamu, kubva ku alloy dzinoenderana ne biocompatible kusvika ku alloys dzemhangura, magumbeze aya anopa mamiriro anodiwa ekugadzira zvinhu zvemhando yepamusoro zvemaindasitiri akasiyana-siyana. Kudzora tembiricha kwakaringana, mhepo uye kuchena kunowanikwa kuburikidza nekunyungudutsa vacuum induction kwakakosha pakuzadzisa zvinodiwa zvakasimba zve alloys dzemazuva ano. Sezvo tekinoroji ichiramba ichifambira mberi, basa re magumbeze evacuum induction mukunyungudutsa alloy richawedzera kukosha mukuzadzisa zvinodiwa zvemaindasitiri akasiyana-siyana.
