Bell Type Annealing Furnace

Anhte a company kaw nna galaw shapraw ai bell type annealing furnace hta, wan wut na shat sha ku, kata na shingnip, katsi ai shingnip, katsi ai ladat, wan n-gun hpe hkrak hkrak hkang lu ai microcomputer langai lawm ai. Bell type annealing furnace hta wan wut na matu sha ku lahkawng, kata na shingnip lahkawng, katsi ai hpe shinggrup da ai. Katsi ai shingnip langai mi, wan wut ai shat sha ku langai mi gaw katsi nna katsi ai hte katsi ai hpe tawn da ai shaloi, kaga wan wut ai table gaw katsi ai hte jahkrat ai lam hta nga ai. Dai katsi ai hpe shinggrup da ai gaw, n-gun hpe hkye la na matu hte matut manoi galaw shapraw lu na matu, wan wut ai table lahkawng hpe galai shai ai hku katsi shangun ai.

Katsi ai-rolled strip steel a annealing process system hpe madung hku nna, n-gang a chemical n-gun, dai arung arai a hpaji masa ni, strip steel a kaba ai hte coil a n-gun zawn re ai lam ni hku nna dawdan ai. Process system gaw, galaw shapraw ai shaloi, coil layers lapran hta n-gun n rawng ai sha, ntsa kaw oxidation n nga ai hpe sadi ra ai.

A. Hka lum ai lawan ai hpe dawdan ai lam N-gang hpe katsi shangun ai lawan ai lam hpe madung hku nna thermal conductivity a kaba ai hku nna dawdan ai. Dai n-gang hta nga ai carbon n-gun hte alloy n-gun gaw, katsi ai hpe n-gun jaw ai lam hta grai n-gun ja ai. Shanhte a content grai law ai rai yang, thermal conductivity gaw kaji ai, katsi ai lawan ai lam gaw kata hte shinggan lapran na grai katsi ai hpe koi lu na matu, n bung ai wuhpung wuhpawng hte bungli galaw ai lam hpe byin shangun ai. Nta kata na nbung katsi ai kaw nna 400℃du hkra, nbung laru a lawan ai lam hpe madung hku nna n pat shingdang ai. Crystallization galaw ai lam a npawt tara hku nga yang, strip steel a kata na hkrang gaw nta kata na nbung katsi ai kaw nna 400℃de grai n galai shai ai. Rolling galaw ai hta elongated mam ni gaw ya sha bai hkam kaja wa sai hte recrystallization hpe garai n galaw shi ai. Dai majaw, ndai range hta n-gang a n-gun grau lawan ai gaw grau kaja na re. Dai strip steel gaw 400℃kaw nna n-gun n-gun hpe hkam la lu ai, nbung katsi ai gaw strip steel a bungli galaw ai lam hte ntsa lam hpe grai hkra machyi shangun ai. Hka lum ai n-gun gaw 30-50℃/h re ngu nna yawng tsun da ai. Strip steel hpe 400℃kaw nna 723℃npu de n-gun dat ai aten laman, dai gaw recrystallization byin pru wa ai aten re. Dai majaw, ndai nbung katsi ai shara hta nbung katsi ai hpe hkang ra ai.

B. N-gun n-gun hte hkam la ai aten hpe dawdan ai lam N-gang a recrystallization temperature gaw n-gun n rawng ai nbung katsi ai lam n re. Dai gaw strip steel a kata na hkrang masa hte seng ai. Teng sha galaw shapraw ai hta recrystallization nbung laru hpe 570-720℃lapran na arung arai hte maren lata la ai. Hkap la ai aten hpe madung hku nna, arung arai madang, hpaji masa, n-gang amyu hte strip galu ai lam ni hpe madung tawn nna dawdan ai. Hkap la ai aten hte hkam la ai nbung katsi ai lam gaw coil a n-gun hte strip a galu kaba ai lam hte mung matut mahkai nga ai. Coil grau li ai hte steel plate grau htum ai hte maren, hkam la ai nbung katsi ai lam grau tsaw wa nna, hkam la ai aten mung grau galu wa ai. Interlayer bonding n kaja ai lam ni hte n-gun n rawng ai strip steel ni hpe hkam sha chye ai n-gang a matu, hkam la ai nbung katsi ai lam gaw hkrak hkrak rai nna, hkam la ai aten gaw kadun mai ai.

C. Bright annealing hpe n-gun n rawng hkra galaw ra ai gaw, strip steel hpe decarburization hte oxidation galaw ra ai. Annealed steel coil ni a oxidation hpe pat shingdang na matu ahkyak ai lam gaw, makawp maga ai shingnip kata na n-gun gaw, galaw sa wa na ra kadawn ai lam ni hpe hkan sa ra ai. Dai hta n-ga, katsi ai hku nbung laru hte katsi ai hpe atsawm sha galaw ra ai. Katsi ai nbung laru hte katsi ai nbung hpe nbung laru hte gap ai a yaw shada lam gaw, kata na shingnip kata na nbung hpe n-gun dat kau na matu makawp maga gas hte n-gang coil kaw na pru wa ai sau, wan hte hka hpe jai lang na matu re. Hot blower a lit gaw, kata na shingnip kata na ngam nga ai gas hpe grau nna shadut ya ai sha n-ga, grau ahkyak ai gaw, n-gun n rawng ai arung arai ni yawng hpe, plate coil kaw nna la sa wa ai emulsion a majaw byin pru wa ai sau wan hkut hte hka n-gun zawn re ai n kaja ai arung arai ni yawng hpe, n-gun n rawng ai hka htung a ntsa hpe awu asin byin shangun nna, n-gang n-gang a ntsa na n-gun hpe shayawm kau na matu, n-gun jaw ai lam ni hpe yeng seng kau ya ai.

Anhte a company gaw, lang ai ni ra sharawng ai hte maren, wan wut ai wan n-ga hte model amyu myu a wan wut ai wan n-ga hpe hkrang shapraw nna galaw mai ai.
