Center qhov siab ntawm cov kab ntau lawm: 1m;

2.3 Technology xaiv cov khoom tiav

Cov cuab yeej ua tiav suav nrog nruab nrab zaus fais fab mov tswj qhov system, far-infrared optical fiber kub ntsuas qhov system, kub kaw-voj tswj qhov system, reactive fais fab nyiaj them nyiaj capacitor bank, induction cua sov annealing rauv lub cev, thiab lwm yam.

Intermediate zaus fais fab tswj qhov system:

2.3.1 Qhov nruab nrab zaus fais fab mov yog thyristor kuj tsis paub meej zaus ntaus ntawv, input voltage yog 380V, 50Hz, thiab cov zis hwj chim yog 200KW. Lub zog tuaj yeem hloov kho manually lossis txiav raws li qhov ntsuas kub. Cov zis zaus yog 8KHz (tsis siv neeg zaus nrhiav). Cov xim ntawm lub txee yog txiav txim siab raws li tus neeg siv yuav tsum tau ua, qhov loj me yog 2000 × 1500 × 1300mm, thiab qhov nruab nrab qhov siab yog 1000mm.

2.3.2 Cartridge hom ua ke silicon khib

Lub rectifier thiab inverter ib feem ntawm thyristor txais qhov tseeb modular ua ke silicon thav duab nrog daim ntawv thov patent. Txoj kev teeb tsa no ua rau lub disassembly thiab sib dhos ntawm thyristor yooj yim dua thiab kev tshawb fawb. Thaum hloov lub thyristor, tsuas yog loosen nws Ib txoj hlua khi tuaj yeem hloov tau txhua yam thyristor hauv lub rooj sib txoos. Tsis tas li ntawd, txoj kev teeb tsa no ua rau txo qhov ntim ntawm SCR tivthaiv, uas tsis yog tsuas yog ua kom qhov chaw khiav hauj lwm hauv lub txee hluav taws xob, tab sis kuj txo cov kab poob.

2.3.6 Main Circuit Parameters thiab Cheebtsam xaiv hauv paus

Cov ntsuas ntsuas ntawm lub ntsiab Circuit Court ntawm qhov nruab nrab zaus fais fab mov yog qhia nyob rau hauv cov lus hauv qab no:

The inductor is composed of a furnace shell, an induction coil, a stainless steel water collector and a furnace lining. The induction coil is combined with the parameters of the annealed copper alloy tube to optimize the design with special computer software and make it in combination with actual experience. It can ensure the best electromagnetic coupling efficiency under the same capacity. Induction coils with 99.99% of T2 rectangular copper wire made, the induction coil outer insulating electrostatic spray process the epoxy resin insulating layer of high strength, pressure-resistant insulating layer is greater than 5000V .

The inner layer of the induction coil is made of white corundum lining, and the outside of the lining and between the coils are fixed with refractory cement (American Union Mine), which can play a role in insulation and heat preservation. At the same time, the strength of the white corundum lining is further increased, effectively avoiding copper wire damage to the lining.

Tag nrho cov dej nyob rau hauv thiab tawm ntawm lub sensor yog sau rau hauv ob lub stainless hlau dej ntxiab, uas yog txuas nrog lub ntsiab dej inlet thiab qhov hluav taws xob kav. Cov khoom siv dej tsis zoo stainless hlau yog qhov zoo nkauj thiab siv tau zoo, uas tuaj yeem zam qhov cuam tshuam ntawm cov cua sov dissipation ntawm induction coil vim corrosion ntawm cov yeeb nkab dej thiab qhov thaiv ntawm txoj kev dej.
