Tungsten Carbide VS HSS (1)

HSS (pfupi yesimbi yepamusoro-soro) ndiyo yaive yakajairwa midziyo yekucheka simbi munguva yakapfuura. Pakagadzirwa tungsten carbide, yaionekwa seyakatsiviwa yakananga simbi inomhanya nekusimba kwakanaka, kupfeka kwakanakisa kuramba, uye kuomarara kwakanyanya. Cemented carbide inowanzofananidzwa nesimbi inomhanya-mhanya nekuda kwekushandisa kwakafanana uye kuoma kwakanyanya.

Kuita kwe tungsten carbide

Tungsten carbide iine micron-sized metal carbide powder iyo yakaoma kunyunguduka uye ine kuoma kwakanyanya. Iyo binder inogadzirwa kubva kucobalt, molybdenum, nickel, nezvimwe. Inoputirwa pakupisa kwakanyanya uye kudzvinyirira kwakanyanya. Tungsten carbide ine yakakwirira-tembiricha carbide zvirimo pane yakakwirira-kumhanya simbi. Iyo ine HRC 75-80 uye yakanakisa kupfeka kuramba.

Zvakanakira tungsten carbide

1. Kuoma kwakatsvuka kwe tungsten carbide kunogona kusvika 800-1000 ° C.

2. Kucheka kumhanya kwecarbide ndeye 4 kusvika ku7 nguva yesimbi yakakwirira. Kucheka kushanda kwakakwirira.

3. Upenyu hwebasa remuumbi, maturusi ekuyeresa, uye maturusi ekucheka akagadzirwa netungsten carbide ndeye 20 kusvika ku150 nguva yesimbi yesimbi alloy.

4. Carbide inogona kucheka zvinhu nekuoma kwe50 HRC.

Kuipa kwe tungsten carbide

Iine simba rekukotama rakaderera, kusimba kwakashata, brittleness yakakwirira, uye kushomeka kwekushomeka.

HSS Performance

HSS yakakwira kabhoni yakakwira alloy simbi, iri simbi yemudziyo ine kuoma kwepamusoro, kukwirira kupfeka kusagadzikana, uye yakakwirira-yekudzivirira. Mumamiriro ekudzima, iron, chromium, partial tungsten, uye kabhoni mune yakakwirira-kumhanya simbi inoumba yakanyanya kuomarara carbide, inovandudza kusamira kwesimbi. Imwe chidimbu chetungsten inonyungudika mukati mematrix, ichiwedzera kuomarara kwesimbi kusvika 650°C.

Benefits yeHSS

1. Kusimba kwakanaka, kusimba kwakanakisa, kunopinza kwekucheka.

2. Hunhu hunoenderana, hunowanzo shandiswa kugadzira midziyo midiki yakaoma-yakaoma.

Zvakaipa zveHSS

Kuoma, hupenyu hwebasa uye HRC yakanyanya kuderera pane tungsten carbide. Pakupisa kwepamusoro kwe600 ° C kana kupfuura 600 ° C, kuoma kwesimbi yepamusoro kuchaderedzwa zvikuru uye haigoni kushandiswa.
