Iipleyiti zentsimbi ezikwaziyo ukunxitywa ziquka ipleyiti yentsimbi enekhabhoni ephantsi kunye ne-alloy engagugiyo umaleko, kunye nomaleko ongagugiyo wealloyi oquka i-1/3 ukuya kwi-1/2 yobunzima bubonke. Ngexesha lokusebenza, izinto ezisisiseko zibonelela ngeempawu ezibanzi njengamandla, ukuqina, kunye ne-ductility ukuxhathisa amandla angaphandle, ngelixa i-alloy wear-resistant layer ibonelela ngokumelana nokunxiba okulungiselelwe iimeko ezithile zokusebenza.
I-alloy inxibe-resistant layer kunye nesiseko sezinto ziboshwe nge-metallurgically. Ukusebenzisa izixhobo ezikhethekileyo kunye nenkqubo ye-welding automated, ubunzima obuphezulu, i-self-shielding wire alloy wire idityaniswe ngokufanayo kwizinto ezisisiseko. Umaleko odibeneyo unokuba mnye, ezimbini, okanye zibe ninzi. Ngenxa yokwahluka kwe-alloy shrinkage ratios, iintanda ezinqamlezileyo ezifanayo ziphuhla ngexesha lenkqubo ye-lamination, uphawu lweepleyiti zentsimbi ezinxitywayo.
I-alloy wear-resistant layer yenziwe ngokukodwa nge-chromium alloy, kunye nezinye izinto ezixutywayo ezifana ne-manganese, i-molybdenum, i-niobium, kunye ne-nickel yongezwa. I-carbides kwisakhiwo se-metallographic i-fibrous, kunye ne-fibers oriented perpendicular to the surface. I-carbide microhardness inokufikelela ngaphezu kwe-HV 1700-2000, kwaye ubunzima bomhlaba bunokufikelela kwi-HRC 58-62. I-alloy carbides izinzile kakhulu kumaqondo obushushu aphezulu, igcina ubulukhuni obuphezulu kunye nokumelana ne-oxidation egqwesileyo, evumela ukusebenza okugcweleyo ngaphakathi kwamaqondo obushushu ukuya kuthi ga kwi-500 ° C.
Uluhlu olungagungqiyo lunokuvela kwiipateni ezincinci (2.5-3.5mm) okanye ububanzi (8-12mm), kunye neepatheni ezigobileyo (S kunye neW). Ngokuyintloko iqulunqwe ngeealloyi ze-chromium, ezi ngxube ziqulethe i-manganese, i-molybdenum, i-niobium, i-nickel, kunye ne-boron. I-carbides isasazwa kwipatheni ye-fibrous kwisakhiwo se-metallographic, kunye neefayili ezihamba nge-perpendicular kumphezulu. Ngomxholo we-carbide we-40-60%, i-microhardness inokufikelela kwi-HV1700, kwaye ubunzima bomhlaba bungafikelela kwi-HRC58-62. Iipleyiti zentsimbi ezikwaziyo ukunxiba zihlulwe kakhulu zibe ziindidi ezintathu: injongo-jikelele, ukumelana nempembelelo kunye nobushushu obuphezulu. Ubunzima obupheleleyo beepleyiti zetsimbi ezingagugiyo bunokuba buncinci njenge-5.5 (2.5 + 3) mm kunye nobukhulu obungama-30 (15 + 15) mm. Iipleyiti zentsimbi ezikwaziyo ukunxiba zinokuqengqeleka kwimibhobho ekwaziyo ukunxiba enobuncinci bedayamitha ye-DN200, kwaye inokucutshungulwa ibe yingqiniba ekwaziyo ukunxiba, iiteyi ezixhathisayo kunye nezinciphisi ezixhathisayo.
