Txoj kev loj hlob ntawm steel yeeb nkab ntau lawm tshuab pib nyob rau hauv lub nce ntawm lub tsheb kauj vab kev lag luam, kev loj hlob ntawm cov roj nyob rau hauv thaum ntxov 19th caug xyoo, kev tsim cov nkoj, boilers, thiab aircraft thaum lub sij hawm ob ntiaj teb no ua tsov ua rog ntawm Tuam Tshoj, kev tsim hluav taws xob hluav taws xob. boiler tom qab Tsov Rog Thoob Ntiaj Teb thib 2, kev txhim kho ntawm kev lag luam tshuaj, thiab kev tsim cov tshuaj lom neeg kev lag luam thiab kev tsim cov tshuaj lom neeg kev lag luam thiab kev drilling thiab kev thauj mus los ntawm cov roj thiab roj tau txhawb kev txhim kho cov yeeb nkab steel kev lag luam ntawm ntau yam. , tso zis thiab zoo.
Cov kav hlau tsis yog tsuas yog siv los thauj cov kua thiab cov hmoov av, sib pauv thermal zog, tsim cov khoom siv kho tshuab thiab ntim khoom. Nws kuj yog ib qho kev lag luam hlau. Kev siv cov yeeb nkab steel los tsim cov phiaj xwm vaj tsev, ncej thiab cov cuab yeej cuab tam tuaj yeem txo qhov hnyav, txuag 20-40% ntawm cov hlau, thiab tuaj yeem ua tiav lub Hoobkas kev tsim kho tshuab.
Seamless steel kav thiab stainless hlau kav yog ob pawg ntawm daim ntawv thov dav. Seamless steel kav yog ib qho tseem ceeb raw cov ntaub ntawv nyob rau hauv kev lag luam kev tsim kho, thiab lub npe hu ua industrial "cov hlab ntsha".
Seamless kav yog dav siv raws li cov neeg kho tshuab cov kav dej (feem ntau yog hydraulic thiab pneumatic lub tog raj kheej raj, hydraulic roj kav, tsheb kis ncej kav thiab semi-axis tes tsho, bearing steel kav, siv kis tau tus mob cov menyuam raj, luam ntawv thiab dyeing rollers, thiab lwm yam.) Petroleum geological industrial yeeb nkab (roj twj tso kua mis yeeb nkab, drilling yeeb nkab, roj yeeb nkab, lub tes tsho, laum pas nrig, thiab lwm yam), chemical pipes (petroleum cracking pipes, high pressure tubes, chemical equipment and pipeline pipelines), fais fab mov boiler thiab tshav kub exchanger twj raj tos.
