Strailed steel kav yog ib hom vuam steel yeeb nkab. Hais txog cov yeeb nkab steel ntawm txoj kab ntsug ntsug ntawm qhov sib txuas thiab cov yeeb nkab steel. Tom qab qhov kub-dov steel yob meridian yog tsim, cov hlau yob tau hloov mus rau hauv cov duab cylindrical. Lub arc combustion nyhuv ntawm high-frequency tam sim no ntawm daim tawv nqaij thiab cov nyhuv ntawm cov neeg nyob sib ze los yog cov nyob ze cov nyhuv los yog cov nyob ze cov nyhuv los yog lub arc nyob rau hauv lub waee txheej yuav welded, thiaj li hais tias cov ntug ntawm cov yeeb nkab billet yog rhuab thiab melted, melted, thiab nws thiaj li txias. Yog lawm. Petroleum, metallurgy, kev tsim kho, thee mines, ports, machinery thiab lwm yam kev lag luam yog dav siv nyob rau hauv kev lag luam xws li roj thiab roj tsheb thauj mus los, low-pressure water and gas, mine fluid transport, band conveyor, and automotive transmission shafts.
Kev tsim cov txheej txheem ntawm ncaj stitched steel kav
1. Kev kuaj xyuas cov hlau phaj: Ua ntej steel phaj ua, nws yuav ua ultrasound nrhiav kom tau zoo tiv thaiv cov hlau tsis tsim nyog nkag mus rau cov kab ntau lawm;
2. Muab tso rau: Mills cov npoo ntawm cov hlau phaj los ntawm milling tshuab rau milling. Vim tias qhov sib txawv ntawm txoj kab uas hla yog qhov loj thiab me, cov phaj steel kuj dav thiab nqaim tom qab cov khoom siv, kom nws tuaj yeem ua tiav qhov dav ntawm cov phaj steel thiab ntug ntawm lub phaj. Parallelism thiab toj - qhov ncauj zoo;
3. Pre-bending: Siv lub tshuab ua ntej-bending rau pre-bending rau ntawm ntug ntawm lub rooj tsavxwm, ua tau raws li qhov yuav tsum tau ua ntawm curvature, thiab lub thickness ntawm lub thickness yuav siv tau rau pre-bending.
4. Rau molding: Ua ntej ntawm tag nrho cov, ib nrab ntawm cov hlau phaj tom qab lub pre-curved steel phaj yog crushed ntau zaus kom nws "J" zoo, thiab ces ib nrab ntawm cov hlau phaj yog ua nyob rau hauv tib lub lag luam, uas yog nias rau hauv "C" duab. "O" shape
5. Pre-welding: Tom qab molding, pawg ncaj seam steel yeeb nkab yuav welded nrog thib ob lav vuam
6. Internal welding: Siv cov kab ntsug -wire faus arc vuam (txog plaub hlau) nyob rau sab hauv ntawm qhov loj -inch welded yeeb nkab Hoobkas;
7. Sab nraud welding: Siv cov kab faus rau hauv arc vuam nyob rau hauv pawg ncaj seam steel yeeb nkab rau vuam.
8. Kho: Kho cov kav hlau steel ntawm tag nrho cov hauv paus welding tshuab kom paub tseeb tias qhov loj me yuav tsum tau ua los ntawm cov neeg siv khoom thiab txhim kho qhov kev faib tawm ntawm kev ntxhov siab hauv cov yeeb nkab steel;
9. Kev kuaj xyuas: Rau cov neeg siv khoom xav tau, qhov ncaj seam steel yeeb nkab ntawm pawg yog ua los ntawm ultrasonic tube los yog X-ray nrhiav, hydraulic siab kuaj, thiab tseem tuaj yeem nqa tawm.
