Lub PC rebar tshav kub kho cov kab ntau lawm ua haujlwm li cas?

PC steel bar yog cov ntawv luv ntawm prestressed qhob steel bar. Qhov saum npoo ntawm steel bar yog threaded thiab tuaj yeem ua raws li cov pob zeb zoo. Kev kho cua sov ntawm PC steel tuav muaj xws li nruab nrab zaus preheating, siab zaus kawg cua sov, quenching, thiab intermediate zaus tempering. Nws cov kev kho cua sov ntau lawm muaj xws li xovxwm conveyor, cua sov induction kauj, quenching chamber, tempering induction kauj, straightening tshuab, txiav tshuab thiab hais txog.

Vim tias qhov ntim ntau lawm ntawm PC steel rebar ua cov kab ntau lawm, qhov zoo ntawm cov kab ntau lawm yog ntsuas. Ntxiv nrog rau cov khoom zoo, cov ntsuas kev siv hluav taws xob yog ib qho tseem ceeb. Luoyang Songdao Induction Cua sov Technology Co., Ltd. pom zoo ib txheej ntawm induction hardening thiab tempering tshuab rau kev kho mob ntawm prestressed qhob steel tuav rau lub tsev, choj piers, thiab pob zeb ncej. Cov kab ke no tseem tuaj yeem siv los tsim lwm cov concave rebars, steel hlau, thiab cov kab hlau puag ncig. Tag nrho cov txheej txheem hloov cov cua sov ncaj qha rau cov cua sov zaum kawg. Lub kaw lus yog tsim los ua cov hlau tuav nrog txoj kab uas hla ntawm 6-12mm thiab pub ntawm qhov nrawm ntawm 35m / min.

Lub kaw lus siv cov khoom siv hluav taws xob nruab nrab rau preheating, lub zog-xeev siab zaus fais fab mov rau qhov kawg cua sov ua ntej quenching, thiab lwm qhov nruab nrab zaus fais fab mov rau tempering. Cov cua kub ua ntej quenching yog 940 ~ 950, thiab tempering kub yog 400. Lub kaw lus kuj tseem nruab nrog rebar pub qhov cua tiv thaiv, kev tswj fais fab sib haum mus rau kev pub ceev, circulating dej txias twj tso kua mis chaw nres tsheb thiab quenching cua txias nruab nrab ncig system. Lub txee tswj tsuas yog cuam tshuam tag nrho cov haujlwm tseem ceeb.

Cov txheej txheem ntawm induction hardening thiab tempering ntawm PC steel tuav yog qhia nyob rau hauv daim duab 8-43: lub steel bar yog blackened, txias drawn, hloov dua siab tshiab, preheated (hauv qab Curie point), rhuab (saum lub Curie point), quenched, thiab qhuav. Tempering cua sov-txias-drying-roll bale. Muaj ib lub tshuab txiav nyob rau hauv pem hauv ntej ntawm lub nras nruas, uas yuav qhib tau thaum lub nras puv.
