Cov Txheej Txheem Ua Haujlwm ntawm AH32, AH36, thiab AH40 Shipbuilding Phaj

AH32, AH36, thiab AH40 Shipbuilding Phaj yog cov ntaub ntawv tseem ceeb hauv kev lag luam shipbuilding, renowned rau lawv superior zoo thiab kev ua tau zoo. Cov txheej txheem ua haujlwm ua haujlwm hauv lawv cov khoom tsim tau zoo heev thiab meej kom ua tau raws li cov kev cai nruj ntawm kev siv dej hiav txwv.

Cov txheej txheem tsim khoom pib nrog kev ua tib zoo xaiv cov khoom siv raw. High-quality steel ingots los yog slabs yog sourced, kom ntseeg tau tias lawv muaj cov tshuaj tsim nyog muaj pes tsawg leeg thiab txhua yam khoom. Cov ntaub ntawv nyoos no tau raug tshuaj xyuas kom zoo kom tshem tawm cov impurities lossis qhov tsis xws luag uas tuaj yeem cuam tshuam qhov zoo ntawm daim hlau kawg.

Cov theem tom ntej no suav nrog cua sov cov ntaub ntawv raw hauv qhov chaw tswj qhov cub rau qhov kub thiab txias. Cov txheej txheem cua sov no tau saib xyuas zoo thiab tswj kom ua tiav cov cua sov zoo thoob plaws hauv cov khoom. Thaum rhuab mus rau qhov xav tau qhov kub thiab txias, steel undergoes kub dov.

Kub dov yog ib kauj ruam tseem ceeb hauv kev ua cov shipbuilding daim hlau. Cov hlau rhuab tau dhau los ntawm cov txheej txheem ntawm cov menyuam hauv qab kev kub ntxhov, maj mam txo nws cov thickness thiab shaping nws rau hauv daim hlau. Cov txheej txheem ntawm cov txheej txheem kub dov, xws li dov ceev, kub, thiab txo qhov sib piv, yog tswj kom tau raws li qhov xav tau phaj qhov ntev thiab cov khoom siv tshuab.

Tom qab kub dov, cov phaj tau txais kev tswj kom txias. Qhov no yog theem tseem ceeb vim nws cuam tshuam rau microstructure thiab cov khoom kawg ntawm cov hlau. Qhov sib txawv ntawm cov cua txias thiab cov txheej txheem yog ua haujlwm nyob ntawm qib tshwj xeeb ntawm cov phaj (AH32, AH36, lossis AH40) kom ua tiav qhov kev xav tau ntawm kev sib xyaw ua ke ntawm lub zog, tawv, thiab ductility.

Cov txheej txheem kev kho cua sov tom qab yuav raug coj los ua kom zoo dua cov khoom ntawm cov phiaj. Cov no muaj xws li annealing, normalizing, los yog tempering. Annealing pab txo cov kev ntxhov siab sab hauv, txhim kho ductility, thiab kho cov microstructure. Normalizing txhim khu lub uniformity ntawm lub microstructure thiab txhim kho cov neeg kho tshuab zog. Tempering feem ntau yog siv los ua kom lub zog ntawm cov phaj.

Kev tswj kom zoo yog ib feem tseem ceeb ntawm kev ua haujlwm. Thoob plaws hauv cov txheej txheem tsim khoom, cov qauv raug coj mus rau ntau theem rau kev tshuaj xyuas thiab kev sim. Kev ntsuam xyuas cov cuab yeej cuab tam, xws li lub zog tensile, lub zog tawm los, elongation, thiab cov kev ntsuam xyuas toughness, yog ua los xyuas kom meej tias cov phaj ua tau raws li cov qauv teev tseg. Cov kev kuaj tsis yog kev puas tsuaj, zoo li kev kuaj ultrasonic thiab kev tshuaj xyuas cov khoom sib nqus, yog siv los txheeb xyuas cov teeb meem sab hauv lossis qhov chaw.

Cov theem kawg suav nrog kev txiav cov phiaj rau qhov ntau thiab tsawg thiab cov duab uas siv cov txheej txheem txiav siab, xws li plasma txiav lossis laser txiav. Cov phaj tom qab ntawd raug rau cov txheej txheem kho saum npoo, xws li txhaj tshuaj blasting lossis pleev xim, txhawm rau txhim kho lawv cov kev tiv thaiv corrosion thiab zoo li.

Hauv kev xaus, cov txheej txheem ua tiav ntawm AH32, AH36, thiab AH40 Shipbuilding Phaj koom nrog cov txheej txheem nyuaj thiab raug tswj xyuas. Cov txheej txheem no, ua ke nrog kev tswj xyuas kom zoo, xyuas kom meej tias cov phiaj xwm ua tau raws li cov qauv siab xav tau los ntawm kev lag luam shipbuilding, muab cov khoom siv txhim khu kev qha thiab ruaj khov rau kev tsim cov nkoj thiab lwm cov nkoj hauv hiav txwv.
