Structural Steel Factory Hall Kuvaka Yakagadzirirwa kuEurope neAmerica Standard Market

Hunhu hwesimbi isimba repamusoro, huremu huremu, kunaka kwese kuomarara, uye kushorwa kwakasimba kune deformation, saka inonyanya kukodzera kuvaka zvivakwa zvakakura-refu, zvepamusoro-soro, uye zvinorema zvakanyanya;izvo zvinhu zvine homogeneity yakanaka uye isotropy, uye yakanakira elasticity Muviri unonyanya kuenderana nekutanga fungidziro dze general engineering mechanics;zvinhu zvine purasitiki yakanaka uye kuoma, inogona kuva nedeformation yakakura, uye inogona kumira zvakanaka mitoro ine simba;nguva yekuvaka ipfupi;dhigirii rayo rekugadzira maindasitiri rakakwira, uye kugadzirwa kwehunyanzvi nedhigirii remakanisa yakakwira inogona kuitwa.

Chimiro chesimbi chinofanira kudzidzwa nesimbi yakakwirira-yakasimba kuti iwedzere zvikuru goho rayo simba;uyezve, mhando itsva dzesimbi dzinofanira kukungurutswa, dzakadai sesimbi yakagadzirwa neH (inozivikanwawo sesimbi yakafara-flange) uye T-yakaumbwa nesimbi uye mahwendefa esimbi ane profiled, etc. Kudiwa kwezvivakwa zvepamusoro-soro.

Mukuwedzera, kune chiedza chesimbi chimiro system pasina kupisa zambuko.Chivako chacho pachacho hachisi chekuchengetedza simba.Iyi tekinoroji inoshandisa akangwara akakosha ekubatanidza kugadzirisa dambudziko rekutonhora uye kupisa mabhiriji muchivako.Iyo diki truss chimiro inobvumira tambo nemapombi emvura kupfuura nemumadziro.Kushongedza Kwekuvaka kuri nyore.

Zvinodiwa:

Kuita:

1. Simba:

Iyo indekisi yesimba resimbi inoumbwa ne elastic muganho σe, goho muganho σy, uye tensile muganho σu.Iyo yakagadzirwa inobva pakusimba kwegoho resimbi.Kusimba kwegoho repamusoro kunogona kuderedza huremu hwechimiro, kuchengetedza simbi, uye kuderedza mutengo.Iyo tensile simba σu ndiyo yakanyanya kushushikana iyo simbi inogona kumira pamberi pekutadza.Panguva ino, chimiro chinorasikirwa nekushanda kwayo nekuda kwepurasitiki yakakura deformation, asi chimiro hachina kukanganisa uye hachiputsi, chinosangana nezvinodiwa zvechimiro chekudzivisa kudengenyeka kusingawanzoitiki.'Σu / σy kukosha kunogona kutariswa separamita yesimbi simba rekuchengetedza.

2. Plasticity:

Iyo plasticity yesimbi inowanzo reva chivakwa chekuve neakakosha epurasitiki deformation pasina kutyora mushure mekushushikana kwapfuura iyo goho poindi.Iwo main indexes kuyera epurasitiki deformation kugona kwesimbi kurebesa δ uye chikamu shrinkage ψ.

3. Kutonhora kwekukotama kuita:

Iko kutonhora kwekukotama kuita kwesimbi chiyero chekuramba kwesimbi kutsemuka kana deformation yepurasitiki ikaitika pakamuri yekupisa.Iyo inotonhora yekukotama kuita kwesimbi ndeye kushandisa inotonhora yekukotama kuyedza kuyedza kubhenda deformation kuita kwesimbi pasi pedhigirii rekukotama rakatsanangurwa.

4. Kuoma kwesimba:

Iko kusimba kwesimbi kunoreva kugona kwesimbi kutora mechanical kinetic simba panguva yekutyoka pasi pemutoro wekukanganisa.Icho chinhu chemuchina chinoyera kupikisa kwesimbi kuti ibate mutoro.Inogona kukonzera brittle kutyoka nekuda kwekudzikira tembiricha uye kushushikana mupfungwa.Iyo kukanganisa kuoma indekisi yesimbi inowanzo kuwanikwa kuburikidza nemhedzisiro bvunzo yeyakajairwa bvunzo zvidimbu.

5. Welding performance:

Welding performance yesimbi inoreva welding majoini nekuita kwakanaka pasi pemamwe welding process mamiriro.Welding performance inogona kukamurwa kuita welding performance uye welding performance mune welding process.Welding performance in the welding process inoreva kubatwa kweiyo welding seam uye simbi padhuze newelding seam kuti irege kutsemuka inopisa kana kutonhora kutsemuka kwakatsemuka panguva yewelding process.Kuita zvakanaka welding kunoreva kuti pasi pemamwe welding process mamiriro, iyo weld simbi uye iri pedyo base simbi haizotsemuka.Kushanda kwewelding maererano nekugona basa kunoreva kusimba kwekuita uye ductility yenzvimbo yakakanganiswa nekupisa pane weld seam.China inotora iyo welding performance test nzira muwelding process, uye zvakare inotora iyo welding performance test nzira muchimiro cheusability.

6. Kugara kwenguva refu:

Pane zvinhu zvakawanda zvinokanganisa kusimba kwesimbi.Yekutanga ndiyo yakashata corrosion resistance yesimbi, uye matanho ekudzivirira anofanirwa kutorwa kudzivirira kuparara kwesimbi uye ngura.Matanho ekudzivirira anosanganisira: kugara uchigadzirisa pendi dzesimbi, kushandiswa kwesimbi yakakoshwa, uye kushandiswa kwematanho akakosha ekudzivirira pamberi pehupombi hwakasimba hunoodza senge acid, alkali, uye munyu.Iyo zinc ingot inogadziriswa pajasi, uye mvura yegungwa electrolyte ichangoerekana yaparadza zinc ingot kutanga, kuitira kuti iwane basa rekudzivirira jekete resimbi.Chechipiri, nekuda kwekushisa kwepamusoro uye mutoro wenguva refu, simba rekuparadza resimbi rakaderera pane iro resimba renguva pfupi.Nokudaro, iyo yakareba-yepamusoro-yepamusoro simbi inofanira kuongororwa kuti iwane simba renguva refu.Iyo simbi inozongove yakaoma uye brittle nekufamba kwenguva, inova chiitiko che "kuchembera".Iko kukanganisa kuoma kwesimbi pasi petembiricha yakaderera inoyedzwa.

Zvigadzirwa zvesimbi zvekambani yedu zvinogona kusangana nemhando dzakasiyana dzepasi rose senge Australian standard, New Zealand standard, British standard uye American standard.Gamuchira kubvunza kwako.
