Ɔkwan bɛn so na induction heating hyerɛn annealing fononoo yɛ adwuma?

Nnyinasosɛm a ɛwɔ induction heating heat treatment mu ne sɛ wɔde adwuma no bɛhyɛ inductor (coil) no mu. Sɛ wɔde frequency pɔtee bi a ɛsesa kɔ inductor no mu a, magnetic field a ɛsesa no yɛ nea atwa ho ahyia. Electromagnetic induction a ɛwɔ alternating magnetic field no mu no ma current a wɔato mu ba wɔ adwuma no mu —eddy current. Nsu a wɔde ahyɛ mu no kyekyɛ wɔ adwuma no fã a ɛwɔ ntwemu no so no nyɛ pɛpɛɛpɛ koraa, na mprempren density a ɛwɔ adwuma no ani no yɛ kɛse yiye na ɛkɔ fam nkakrankakra kɔ mu. Wɔfrɛ saa adeyɛ yi sɛ honam ani hwɛbea. Wɔdan anyinam ahoɔden a ɛwɔ current a ɛyɛ den a ɛwɔ adwuma no ani no mu no ma ɛdan ɔhyew ahoɔden, na ɛma ɔhyew a ɛwɔ soro no yɛ kɛse, kyerɛ sɛ, ɛma ɔhyew a ɛwɔ soro no yɛ kɛse. Dodow a current frequency no kɔ soro no, dodow no ara na current density nsonsonoe no yɛ kɛse wɔ soro layer ne mu wɔ adwuma no mu, na ɛyɛ teateaa wɔ ɔhyew no mu. Wobetumi anya ɔfasu no dum denam onwini a ɛyɛ ntɛmntɛm so bere a ɔhyew a ɛwɔ ɔhyew no mu no ayɛ kɛse no asen ɔhyew a ɛho hia a ɛwɔ dade no mu no.

Metallographic structure a ɛwɔ dadeɛ mu no bɛkyerɛ nhyehyɛeɛ tebea ahodoɔ wɔ ɔhyeɛ ahodoɔ mu. Bio nso, sɛ wɔma ɛyɛ hyew kodu ɔhyew bo pɔtee bi so na ɛba fam mpofirim kɔ ɔhyew bo a ɛba fam foforo mu a, ɛbɛda nhyehyɛe soronko nso adi.

Induction heating ne sɛ ɛbɛma adwuma no ayɛ hyew akodu ɔhyew pɔtee bi mu denam electromagnetic field so na afei wɔayɛ post-processing sɛnea ɔhyew ayaresa ahwehwɛde ahorow te. Sɛ nhwɛso no, sɛ wodum no a, ɛma ɛyɛ hyew kodu digrii awotwe anaa ahankron, na afei mpofirim ara ɛyɛ no nwini wɔ digrii ɔha anaa bɛyɛ digrii ɔha mu.

Akwan pii wɔ hɔ a wɔfa so yɛ ɔhyew a wɔde yɛ ɔhyew, te sɛ fononoo mu ɔhyew a ɛko tia, gas a wɔde yɛ hyew, ne nea ɛkeka ho Mfaso a ɛwɔ induction ɔhyew so ne efĩ a ɛba fam, nneɛma a atwa yɛn ho ahyia ho adamfofa, ahoɔden a ɛkorɔn ne nea ɛkeka ho.. Afiri a wɔde yɛ ɔhyew a ɛkɔ so yɛ tube induction afiri a wɔde yɛ fononoo a ɛyɛ hyew a ɛyɛ hyew . Efi . Hangao Tech (Seko mfiri) nso betumi aboa wo ma woadi wo mmirikatu ho ka so. Ɛnyɛ sɛ mframa a ɛyɛ den no betumi asiw mframa no ano nko, na mmom ɛbɛma dade a ɛnyɛ den a ɛwɔ dade no mu no anya nkɛntɛnso a ɛhyerɛn. Ebetumi nso atew ɔhyew a ɛyera no so na ama ahoɔden a wɔde di dwuma no atu mpɔn, na ama anyinam ahoɔden a wɔde di dwuma no so atew.
