Sèt metòd chofaj nan aparèy chofaj batri ityòm

1. chofaj rezistans

Se efè a joule nan kouran elektrik itilize konvèti enèji elektrik nan enèji tèmik nan objè chalè . silicone kawotchou chofaj kawotchou se yon kalite patikilyèman mou senti chofaj ki konpoze de nikèl-chromium alyaj fil ak izolasyon . used for heating and heat preservation of general constant power belts, it can also be used in places where heating is required in some cases. The process control during the use of the insulation cover and its influence on the finishing rolling process are analyzed. By statistically analyzing, classifying and arranging the on-site measured data of the hot rolling production line, the main reason for the temperature drop of the strip on the intermediate Woulo analize . aparèy chofaj depo enèji batri a trè mens, limyè ak fleksib .... Avèk aparèy chofaj sa a, ou ka transfere chalè nan nenpòt kote ki vle . pandan tretman, li amelyore transfè chalè, akselere ak redwi pouvwa a pou reziste nan rezistans epi li se pou reziste pou reziste nan indess {}. Nan ansyen an, se vòltaj la ekipman pou pouvwa dirèkteman aplike nan objè a chofe . Lè koule aktyèl, objè a chofe tèt li (tankou silicone kawotchou chofaj machin planch) pral jenere chalè {{13} Efikasite tèmik .

The main materials used for heating elements that indirectly affect resistance for heating are generally required to have large resistivity, small resistance working temperature correlation coefficient, small deformation at high temperature and not easy to embrittle. Commonly used are metal structural materials such as iron-aluminum alloy, nickel-chromium alloy and non-metallic composite materials such as silicon carbide and molybdenum disilicide .

2. chofaj endiksyon

Chofaj endiksyon sèvi ak efè a tèmik ki te fòme pa aktyèl la induit (eddy aktyèl) ki te pwodwi pa kondiktè a nan jaden an altène elektwomayetik chofe kondiktè nan tèt li .

3. chofaj arc

ARC chofaj chofe objè nan tanperati ki wo ki te pwodwi pa ark la . ARC a se yon egzeyat gaz ant de elektwòd . vòltaj la nan ark la se pa wo, men aktyèl la se gwo anpil {{ Field . Lè yon arc ki te fòme ant elektwòd yo, tanperati kolòn ARC la ka rive nan 3000-6000 k, ki apwopriye pou gwo tanperati metal fondri .

4. chofaj gwo bout bwa elèktron

Chofaj gwo bout bwa elèktron sèvi ak elektwon gwo vitès bonbard sifas la nan yon objè anba aksyon an nan yon jaden elektrik chofe objè a . eleman prensipal la nan chofaj gwo bout bwa elèktron se yon dèlko gwo bout bwa elèktron, ke yo rele tou yon zam elèktron {{2} coil. The anode is grounded, the cathode is connected to a negative high position, and the focused beam is usually at the same potential as the cathode, forming an accelerating electric field between the cathode and the anode. The electrons emitted by the cathode are accelerated to a very high speed under the action of the accelerating electric field. They are focused by an electromagnetic Lantiy ak Lè sa a, kontwole pa yon bobin deformation fè gwo bout bwa a elèktron tire nan direksyon objè a chofe nan yon direksyon sèten .

5. chofaj enfrawouj

Chofaj enfrawouj itilize objè enfrawouj . Lè objè a absòbe reyon enfrawouj, enèji radyasyon an konvèti nan enèji chalè ak chofe .

Reyon enfrawouj yo se onn elektwomayetik . nan spectre solè a, deyò fen wouj la nan limyè vizib, li se yon kalite enèji envizib radyasyon . nan spectre la elektwomayetik, 3000 {{{ a 4 × 10 Hz . Nan aplikasyon endistriyèl, se spectre an enfrawouj anjeneral divize an plizyè Gwoup Mizik: 0.75 3.0 mikron se rejyon an tou pre enfrawouj; 3.0 a 6.0 mikron se rejyon an mitan-enfrawouj; 6.0 a 15.0 mikron se rejyon an enfrawouj.
