Continuous casting tundish simbi yakanyungudutswa induction heating equipment

1 Overview

Tundish yakanyungudutswa yesimbi induction yekudziya yemidziyo tekinoroji inogadzirwa nekufambira mberi kwekukandira tekinoroji, kuvandudzwa kwemhando yesimbi zvinodiwa, kudiwa kwekuchengetedza simba uye kuderedza kushandiswa, uye kuenzanisa kwekunatsa kwekunze uye kuenderera mberi kwekukanda maitiro. Akasiyana simbi mamakisi ane akasiyana zvinodiwa paAT yesimbi yakanyungudutswa superheat. Kune mahwendefa akakora, kuitira kuderedza mukati mekuputika uye nzvimbo yakasununguka, AT inofanira kunge yakaderera (5 ~ 200T); kune inotonhora-yakakungurutswa yakatetepa mahwendefa, iyo yepamusoro inodiwa kuti ive nemhando yakanaka. Pamusoro (15 ~ 300 ℃). Nekudaro, iyo yakanyungudutswa simbi superheat inofanirwa kudzikamiswa mukati meimwe siyana kuti ideredze kushanduka. Ichi chiitiko chinodiwa kuti uve nechokwadi chekufambira mberi kwakanaka kwekuenderera mberi kwekugadzira, kudzivirira kuvharika kwenozzle kana kudzivirira tsaona dzinobuda, uye kuve nechokwadi chemhando yeakakanda slabs. Kuwedzeredzwa kwebasa rekupisa kwe tundish kunoita kuti zvikwanise kudzora kupisa kwakanyanya kwesimbi yakanyungudutswa yakadzikama. Kupisa kwesimbi yakanyungudutswa yeladle yakasiyana-siyana inoshanduka, iyo ine mhedzisiro yakaipa pakuramba ichikanda maitiro, uye kupisa kweiyo tundish kunogona kuibhadhara kune imwe nhanho. Nekudaro, zvinofanirwa kutaurwa kuti kuchengetedza yakagadzika simbi yakanyungudutswa superheat inonyanya kuenderana nekudziya kwakaringana tembiricha uye chimiro chekugadzirisa mushure mekutapa, uye kupisa tundish kunogona chete kutamba chikamu chekuwedzera. Zvakadaro, kudziyisa uye kutonga kwesimbi yakanyungudutswa mu tundish ichiri kugamuchira kutariswa kubva kunharaunda yemetallurgical. Dzimwe nyika dzakamiririrwa neJapan, United States, United Kingdom, neFrance dzakatevedzana dzakaita tsvakiridzo yetundish yakanyungudutswa tekinoroji yekudziya yesimbi kubva kuma1970 kusvika kuma1980. Kawasaki yekuJapan Kawasaki Company yakatanga kugadzirwa nekuwana patent yekuJapan kubva muna 1982. Parizvino, tekinoroji yesimbi yakanyungudutswa yekudziya tekinoroji yakabudirira kugadzirwa kana pasi pekuvandudzwa kazhinji inotora nzira yekudziya. Munzira yekudziya yemuviri, simba remagetsi rinoshandiswa senzvimbo yekupisa uye rinoshandurwa zvinoenderana nesimba remagetsi. Nzira dzakasiyana dzinogona kukamurwa kuita: electromagnetic induction heat equipment, plasma heat, electroslag heat uye DC ceramic heat tekinoroji.

Tundish induction heat yemidziyo ine zvinotevera maitiro:

(1) Kukurumidza kupisa kwekukurumidza uye yakakwira yemagetsi kupisa kunyatsoshanda;

(2) Dzimwe mhando zvakare dzine imwe electromagnetic inosimudzira mhedzisiro, iyo inobatsira kubviswa kweiyo inclusions;

(3) Iyo tembiricha yemaitiro iri nyore kudzora, uye chinonyanya kukosha ndechekunyatso kudzora kupisa kwakanyanya kwesimbi yakanyungudutswa;

(4) Iyo yekupisa simba inoganhurwa nekudzika kweiyo tundish fluid level. Chete kana simbi yakanyungudutswa mu tundish ichiungana kune imwe kudzika, kupisa kunogona kuenderera zvakanaka.

Kune akati wandei marudzi e tundish induction kudziyisa michina:

(1) Zvinoenderana nerudzi rweinductor, inogona kukamurwa kuita coreless induction yekudziya michina uye cored induction yekudziya michina;

(2) Zvinoenderana nechimiro cheinductor, inogona kukamurwa kuita yakawedzera kukanganisa mhando uye tunnel mhando (groove, yakanyungudutswa mugero) induction yekupisa michina;

(3) Zvinoenderana nechikamu chekudziya, chinogona kukamurwa mukudziya kwenzvimbo uye kupisa kwese.
