Ndiro yesimbi isingapfeki

Maplate esimbi asingapedzi ane ndiro yesimbi isina kabhoni yakawanda uye chikamu chisingapedzi che alloy, uye chikamu chisingapedzi che alloy chinowanzova ne 1/3 kusvika 1/2 yeukobvu hwese. Munguva yekushanda, zvinhu zvepasi zvinopa hunhu hwakakwana hwakadai sesimba, kuomarara, uye ductility yekudzivirira masimba ekunze, nepo chikamu chisingapedzi che alloy chichipa kuramba kupfeka kwakagadzirirwa mamiriro chaiwo ekushanda.

Chigadziko chisingapararike nesimbi uye zvinhu zvepasi zvakabatanidzwa nesimbi. Zvichishandisa michina yakasarudzika uye nzira yekuwelda otomatiki, waya yesimbi inosimba zvakanyanya, inozvidzivirira inosungirirwa zvakaenzana kune zvinhu zvepasi. Chigadziko ichi chinogona kuva chikamu chimwe, zviviri, kana kunyange zvakawanda. Nekuda kwekusiyana kwehuwandu hwekupwanyika kwesimbi, mitswe yakafanana inobuda panguva yekukwesha, chiratidzo chemaplate esimbi asingapararike.

Chigadziko che alloy chisingapfeki chinowanzo umbwa ne chromium alloy, pamwe nezvimwe zvinhu zvakaita se manganese, molybdenum, niobium, uye nickel zvakawedzerwa. Carbides iri muchimiro che metallographic ine fibrous, ine fibers dzakatarisana nepamusoro. Kuomarara kwe carbide kunogona kusvika pamusoro pe HV 1700-2000, uye kuomarara kwepamusoro kunogona kusvika HRC 58-62. Carbides dze alloy dzakagadzikana zvakanyanya pakupisa kwakanyanya, dzichichengetedza kuomarara kwakanyanya uye dziviriro yakanaka ye oxidation, zvichibvumira kushanda zvizere mukati mekupisa kusvika 500°C.

Rutivi rusingapfeki runogona kuoneka mumapatani matete (2.5-3.5mm) kana kuti akafara (8-12mm), pamwe nemapatani akakombama (S naW). Zvichinyanya kuumbwa nema chromium alloys, ma alloys aya anewo manganese, molybdenum, niobium, nickel, uye boron. Ma carbides akapararira mu fibrous pattern mu metallographic structure, ne fibers dzichimhanya dzakamira pamusoro. Nehuwandu hwe carbide hwe40-60%, microhardness inogona kusvika pamusoro peHV1700, uye kuoma kwepamusoro kunogona kusvika HRC58-62. Ma plates esimbi asingapfeki akakamurwa zvikuru muzvikamu zvitatu: zvekushandisa zvakanyanya, zvisingapinze uye zvisingapinze zvakanyanya kupisa. Ukobvu hwese hwema plates esimbi asingapfeki hunogona kuva hudiki se5.5 (2.5+3) mm uye hukobvu se30 (15+15) mm. Maplate esimbi asingapedzi anogona kupetwa mumapaipi asingapedzi ane dhayamita shoma yeDN200, uye anogona kugadzirwa kuita magokora asingapedzi, matinji asingapedzi uye zvinoderedza kupisa.
