Girman Tungsten Carbide

Tungsten Carbide, wanda aka sani da haƙoran masana'antu, samfuri ne na yau da kullun. Ya shahara da kyawawan kaddarorinsa waɗanda suka haɗa da ƙarfi mai ƙarfi, ƙarfi mai ƙarfi, babban yawa, juriya, da juriya na lalata, ta yadda, ana iya sanya shi cikin ɗimbin rawar soja daban-daban, masu yankan, kayan hako dutse, kayan aikin hako ma'adinai, sassa, silinda liners. , da sauransu. A cikin masana'antar, za mu yi amfani da sigogi da yawa don gwadawa da tabbatar da cewa samfuran carbide tungsten suna da inganci. A cikin wannan labarin, za a yi magana game da ainihin yanayin jiki, yawa.

Menene yawa?

Maɗaukaki shine mahimmin ƙayyadaddun kayan inji don nuna yawan adadin siminti na siminti kowace juzu'i. Ƙarar da muka ambata a nan, ya haɗa da ƙarar pores a cikin kayan. Dangane da tsarin tsarin raka'a na kasa da kasa da ma'aunin ma'aunin doka na kasar Sin, yawan ma'aunin yana wakilta da alamar ρ, kuma na'ura mai yawa shine kg/m3.

Yawan adadin tungsten carbide

A ƙarƙashin tsarin masana'anta iri ɗaya da sigogi iri ɗaya, ƙarancin simintin carbide zai canza tare da canjin sinadarai ko daidaita ma'aunin albarkatun ƙasa.

Babban abubuwan haɗin YG jerin simintin carbide sune tungsten carbide foda da foda cobalt. Ƙarƙashin wasu sharuɗɗa, yayin da abun ciki na cobalt ya karu, ƙarancin haɗin gwal yana raguwa, amma lokacin da aka kai mahimmancin ƙima, yawan juzu'i yana da ƙananan. A yawa na YG6 gami ne 14.5-14.9g/cm3, da yawa na YG15 gami ne 13.9-14.2g/cm3, da yawa YG20 gami ne 13.4-13.7g/cm3.

Babban abubuwan haɗin YT jerin simintin carbide sune tungsten carbide foda, titanium carbide foda, da foda cobalt. A karkashin wasu yanayi, yayin da abun ciki na titanium carbide foda ya karu, yawan adadin da ke ragewa. YT5 alloy yawa 12.5-13.2g/cm3, YT14 alloy yawa 11.2-12.0g/cm3, YT15 alloy yawa 11.0-11.7g/cm3

Babban abubuwan da aka haɗa na jerin YW cemented carbide sune tungsten carbide foda, titanium carbide foda, tantalum carbide foda, niobium carbide foda, da foda cobalt. A yawa na YW1 gami ne 12.6-13.5g/cm3, da yawa na YW2 gami ne 12.4-13.5g/cm3, da yawa YW3 gami ne 12.4-13.3g/cm3.

Saboda yawan da yake da shi, ana iya yin carbide da aka yi da siminti ya zama samfura iri-iri, kamar na'urorin injina, sanduna masu nauyi da ake amfani da su a masana'antar hakowa kamar mai, ma'aunin agogo, ballasts don tuƙi, tuƙi, da sauransu. , wanda zai iya tabbatar da ma'aunin abubuwa a cikin aiki ko a tsaye, ko kuma ya ceci aikin ma'aikata.

Lura: Girman tungsten carbide foda yana da kusan 15.63g / cm3, nauyin cobalt foda shine game da 8.9g / cm3, yawan adadin titanium carbide foda shine game da 4.93g / cm3, yawancin tantalum carbide foda shine game da 14.3g / cm3, kuma yawan niobium carbide foda yana da kusan 8.47g/cm3.

Abubuwan da ke da yawa na tungsten carbide yawa

Yawa yana da alaƙa da abun da ke ciki, rabon albarkatun ƙasa, microstructure, tsarin samarwa, sigogin tsari, da sauran dalilai. Gabaɗaya magana, filayen aikace-aikacen simintin carbide tare da yawa daban-daban suma sun bambanta. Abubuwan da ke biyo baya suna gabatar da abubuwan da suka shafi tasirin gami da yawa.

1. Abun abun ciki

Cemented carbide za a iya hada da foda biyu, tungsten carbide foda (WC foda) da cobalt foda (Co foda), ko foda uku: WC foda, TiC foda (titanium carbide foda) da Co foda, ko ma WC foda. Foda, TiC foda, TaC foda (tantalum carbide foda), NBC foda (niobium carbide foda), da kuma Co foda. Saboda daban-daban abun da ke ciki na gami kayan, da yawa daga cikin gami ne daban-daban, amma da bulan ne kama: da yawa na YG6 gami ne 14.5-14.9g / cm³, da yawa na YT5 gami ne 12.5-13.2g /. cm³, da yawa na YW1 gami12.6-13.5g/cm³.

Gabaɗaya magana, yawan ƙwayar tungsten-cobalt (YG) cemented carbide yana ƙaruwa tare da haɓaka abun ciki na WC foda. Misali, da yawa na gami da WC foda abun ciki na 94% (YG6 gami) ne 14.5-14.9g/cm³, da kuma WC foda abun ciki The yawa na 85% gami (YG15 alloy) ne 13.9-14.2g/cm³.

Matsakaicin adadin tungsten-titanium-cobalt (YT) ƙarfin gami yana raguwa tare da haɓaka abun ciki na TiC foda. Misali, yawan abubuwan gami da TiC foda abun ciki na 5% (YT5 gami) shine 12.5-13.2g/cm³, kuma abun ciki na TiC foda shine 15%. Girman gami (YT15 alloy) shine 11.0-11.7g/cm³.

2. Karamin tsari

Porosity yafi lalacewa ta hanyar pores da shrinkage kuma alama ce mai mahimmanci don yin la'akari da ingancin simintin carbide. Babban dalilai na samuwar simintin carbide pores sun haɗa da ƙonawa mai yawa, haɗaɗɗun kwayoyin halitta, haɗakar ƙarfe, ƙarancin latsawa, da ma'aikatan gyare-gyare marasa daidaituwa.

Saboda kasancewar pores, ainihin ma'auni na haɗin gwiwar ya kasance ƙasa da ƙayyadaddun ƙididdiga. Mafi girma ko fiye da pores, ƙarancin ƙaƙƙarfan gami yana kan nauyin da aka ba shi.

3. Tsarin samarwa

Tsarin samarwa ya haɗa da tsarin ƙarfe na foda da fasahar gyare-gyaren allura. Lalacewa irin su carburizing, ƙonawa, ɓarna, kumfa, kwasfa, da rashin ƙarfi yayin latsawa da ɓacin rai zai haifar da raguwar ƙarancin simintin carbide.

4. Yanayin aiki

Gabaɗaya magana, tare da canjin zafin jiki ko matsa lamba, ƙarar ko ƙima na gami kuma zai canza daidai, amma canjin ɗan ƙaramin abu ne kuma ana iya yin watsi da shi.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
