Pfeka resistant steel plate

Pfeka inodzivirira simbi ndiro inoumbwa neplate yesimbi yakaderera-kabhoni uye alloy kupfeka-resistant layer.Iyo alloy kupfeka-inodzivirira layer inowanzo 1/3 ~ 1/2 yehupamhi hwese.Panguva yekushanda, iyo matrix inopa yakazara zvimiro senge simba, kuoma uye plastiki kurwisa masimba ekunze, uye alloy kupfeka-resistant layer inopa kupfeka-resistant zvivakwa zvinosangana nezvinodiwa zveakatsanangurwa mamiriro ekushanda.

Iyo inopfeka-inodzivirira simbi ndiro inosungirirwa nesimbi pakati peiyo alloy kupfeka-resistant layer uye substrate.Kuburikidza nemidziyo yakakosha uye otomatiki welding process, iyo yakakwira kuomarara self protective alloy welding wire inokwenenzverwa pane substrate.Huwandu hwematanho akaumbwa ndechimwe kusvika kuviri kana kunyange akawanda.Munguva yemubatanidzwa maitiro, yunifomu yakachinjika mitswe inooneka nekuda kweakasiyana alloy shrinkage ratio, inova chinhu chinoshamisa chesimbi inodzivirira kupfeka.

Iyo alloy kupfeka-resistant layer inonyanya kuumbwa nechromium alloy, uye zvimwe zvikamu zvealloy senge manganese, molybdenum, niobium uye nickel inowedzerwawo.Iyo carbides mune iyo metallographic chimiro yakagoverwa mufiber chimiro, uye iyo fiber kutungamira iri perpendicular kumusoro.Iyo micro kuomarara kwecarbide inogona kusvika pamusoro pehv1700-2000 uye kuoma kwepasi kunogona kusvika HRC58-62.Alloy carbides ane kugadzikana kwakasimba pakupisa kwepamusoro, anochengetedza kuomarara kwakanyanya, uye ane yakanaka oxidation kuramba.Vanogona kushandiswa zvakajairika mukati me500 ℃.

Iyo yekupfeka-inodzivirira layer inotora fomu yakamanikana chiteshi (2.5-3.5mm), yakafara chiteshi (8-12mm), curve (s, w), nezvimwe;Iyo inonyanya kuumbwa nechromium alloy uye zvimwe zviwanikwa zvealloy senge manganese, molybdenum, niobium, nickel uye boron.Iyo carbides mune iyo metallographic chimiro yakagoverwa mufiber chimiro, uye iyo fiber kutungamira iri perpendicular kumusoro.The carbide content is 40-60%, microhardness inogona kusvika kupfuura hv1700, uye kuoma kwepamusoro kunogona kusvika HRC58-62.

Chikamu chekushandisa

Pfeka inodzivirira simbi ndiro ine yakakwirira kupfeka kuramba uye kuita kwakanaka kwekuita.Inogona kutemwa, kukotama uye kusungirirwa.Inogona kubatanidzwa nezvimwe zvimiro newelding, plug welding uye bolt yekubatanidza.Iyo inochengetedza nguva uye iri nyore mukugadzirisa.Inoshandiswa zvakanyanya musimbi, marasha, simende, simba remagetsi, girazi, migodhi, zvekuvaka, zvidhinha uye mataira uye mamwe maindasitiri.Zvichienzaniswa nezvimwe zvinhu, ine mutengo wakakwira kuita, Yakafarirwa neakawanda uye akawanda maindasitiri nevagadziri.
