Iimpawu kunye nokuSetyenziswa kweCemented Carbide

Iimpawu ze-tungsten carbide

I-Tungsten carbide inobunzima obuphezulu kunye nokumelana nokunxiba. Isantya sokusika izixhobo ze-carbide si-4 ukuya kumaxesha angama-7 aphezulu kuneyentsimbi ye-high-speed kunye ne-5 kumaxesha angama-80 ubomi benkonzo ephezulu. Iimveliso zeCarbide zinokusika izinto ezinzima malunga ne-50HRC. Amanqaku aya kwazisa ulwazi olubalulekileyo malunga ne-samente carbide.

Iimpawu zezinto eziphathekayo ze-tungsten carbide

I-carbide ene-cemented ubukhulu becala yi-micro-size powder of carbides (WC, TiC) yobunzima obuphezulu besinyithi. Amacandelo aphambili ziimveliso zemetallurgical engumgubo ezifakwe kwisithando somlilo okanye isithando somlilo se-hydrogen esine-cobalt (Co), i-nickel (Ni), kunye ne-molybdenum (Mo) njengesibophelelo.

I-matrix ye-carbide ene-cemented yenziwe ngamacandelo amabini: enye inxalenye yinqanaba lokuqina, kwaye enye inxalenye yintsimbi edibeneyo.

Isigaba esinzima yi-carbide, njenge-tungsten carbide, i-titanium carbide, kunye ne-tantalum carbide. Ukuqina kwayo kuphezulu kakhulu. Iindawo zayo zokunyibilika zingaphezu kwama-2000°C, kwaye ezinye zide zidlule kwi-4000°C. Ubukho besigaba sokuqina bumisela ubunzima obuphezulu kakhulu kunye nokumelana nokunxiba kwe-carbide.

I-Tungsten carbide yeWC yeemfuno zobungakanani beenkozo zekhabhide enesamente zisebenzisa ubungakanani beenkozo ezahlukeneyo zeWC ngokwezicelo ezahlukeneyo.

Eli nqaku ikakhulu lizisa iindlela ezintathu zokusetyenziswa kwekhabhide enesamente:

1. I-Tungsten carbide yokwenza izixhobo zokusika i-carbide

Izixhobo zokusika i-Carbide zisetyenziselwa ngokubanzi ukusika isinyithi kunye nomatshini. Iialloyi zoomatshini ezintle ezifana neencakuba zokusika iinyawo kunye neemela ze-V-CUT zisebenzisa i-ultra-fine, i-sub-fine, kunye ne-WC ecoliweyo. Iialloyi zoomatshini zisebenzisa ukutya okuziinkozo okuphakathi kweWC. I-gravity cutting alloys kunye ne-heavy-duty cut alloys zisebenzisa i-WC ephakathi kunye ne-coarse Granular njengezinto eziluhlaza.

2. I-carbide enesamente yokwenza izixhobo zemigodi ye-carbide

Ilitye linobunzima obuphezulu kunye nomthwalo wempembelelo ephezulu. I-coarse WC yamkelwa, kwaye impembelelo yelitye incinci kunye nomthwalo omncinci. I-WC enobungakanani obuphakathi isetyenziswa njengemathiriyeli ekrwada.

3. I-Hard alloy yokwenza iindawo ezinqabileyo ze-carbide

Xa kugxininiswa ukuxhathisa ukunxiba, ukumelana noxinzelelo, kunye nokugqitywa komphezulu, i-WC enobukhulu obahlukeneyo isetyenziswa njengezinto eziluhlaza, kwaye i-WC ephakathi kunye ne-coarse-grained-grained WC isetyenziswa njengeyona nto iphambili.

4. Isinyithi esinzima sokwenza i-tungsten carbide Dies

I-carbide dies inamaxesha amaninzi amashumi amaxesha obomi benkonzo obude kunobumba bentsimbi. I-carbide mold inobunzima obuphezulu, amandla aphezulu, ukuxhathisa kwe-corrosion, ukumelana nobushushu obuphezulu, kunye ne-coefficient encinci yokwandisa, ngokubanzi yenziwe nge-tungsten cobalt.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
