2. Taw qhia
Copper Boron Master Alloy yog ib qho zoo heev boron additive rau kev ua tooj liab. Nws kuj yog ib qho tseem ceeb nruab nrab alloys rau deoxidizing tooj liab alloys, txhim kho corrosion kuj thiab ntxiv zog. Nws kuj yog ib qho tseem ceeb additive rau cam khwb cia hlau qhov chaw los txhim kho hardness thiab corrosion kuj. Ib qho me me ntawm boron (0.005-0.05% wt) tuaj yeem txhim kho lub zog thiab corrosion kuj ntawm tooj liab. Tam sim no nws tau siv dav hauv kev tsim khoom thiab kev ua kom txias tooj liab hauv cov khoom siv hluav taws xob.
3. Khoom nta
1. Copper Boron Master Alloy tuaj yeem tshem tawm cov ntxhib columnar crystals hauv lub xeev cam khwb cia ntawm tooj dag. Thaj, ua kom zoo dua cov nplej, txhim kho lub koom haum ntawm cov casting ntom ntom, txo qhov nyiam ntawm loosening, txhim kho cov airtightness ntawm casting. Txhim kho lub zog thiab plasticity ntawm tooj liab rooj kub, txo los yog tshem tawm cov kev sib tsoo ntawm cov yas deformation, txhim kho tus nqi ntawm cov khoom tsim.
2. Cov kua tooj dag muaj cov nyhuv purification zoo heev, tuaj yeem ua ke nrog cov tooj liab kua impurity cov ntsiab lus los tsim cov khoom sib txuas kom tawm, los yog ua kom cov impurity diffusion faib, txo cov impurity nyob rau hauv cov nplej ciam cais, txhim kho cov khoom ntawm cov khoom. .
3. Nws muaj cov nyhuv chemisorption tshwj xeeb thiab muaj kev sib raug zoo rau cov roj atoms, uas tuaj yeem ua ke sai sai nrog cov roj atoms hauv cov kua tooj liab los tsim cov tebchaw rau kev tawm, txo qhov nyiam ntawm subcutaneous pores thiab nto pores los tsim.
4. Kev txhim kho cov kua dej ntawm tooj liab, muaj txiaj ntsig zoo rau kev txhim kho ntawm qhov zoo ntawm cov casting, thiab tuaj yeem daws qhov tshwm sim ntawm qhov chaw pitting.
5. Lub melting point ntawm cov khoom no yog me ntsis qis dua li ntawm tooj dag, yog li nws melts sai, nrog tsawg kub poob, thiab yog ib qho yooj yim thiab zoo rau kev khiav lag luam.
6. Cov nyhuv ntawm refining lub ingots nrog cov khoom no tsis poob tom qab rov remelting.
4. Khoom siv:
Siv rau tooj liab alloy nyob rau hauv sib ntxiv ntawm boron caij, npib siv, filling alloy thiab lwm yam teb thiab industries. Nws cov purity siab ua kom ntseeg tau tias cov ntsiab lus yuav tsum tau ntxiv yam tsis muaj kev qhia txog impurities rau hauv cov khoom siv hauv paus. Qhov tseem ceeb thiab kev siv tseem ceeb ntawm boron - tooj liab alloys
(1). Boron tooj liab alloy feem ntau yog siv los ua additives lossis deoxidizing degassing tus neeg sawv cev rau txhua yam ntawm boron ntsiab (xws li thermal txau (vuam) nws tus kheej-melting alloy, kub kub brazing alloy, amorphous mos magnetic alloy, amorphous kuj alloy, hmoov metallurgy, boron hlau. , thiab lwm yam).
(2). Boron tooj liab alloy yog ib hom kev ua tau zoo boron additive siv hauv kev ua tooj liab. Me me ntawm boron (0.005-0.05% wt) tuaj yeem txhim kho lub zog thiab corrosion kuj ntawm tooj liab. Alloys yog tus cwj pwm los ntawm qhov hnyav tshwj xeeb thiab kev siv siab ntawm boron.
Piv txwv li, tooj liab thiab boron 2% alloys yog txoj hauv kev zoo los txhim kho qhov zoo ntawm tooj liab alloys thiab tooj dag. Lub caij tseem muaj txiaj ntsig zoo dua li lwm cov deoxidizers, xws li phosphorus, lithium lossis magnesium, yog li xav tau boron tsawg dua ib kilogram ntawm oxygen kom ua tiav cov nyhuv deoxidizing tib yam. Nyob rau hauv tooj liab alloys, boron kuj retards grain loj hlob thaum cua sov. Tsis tas li ntawd, boron yooj yim pouring thiab sau. Nws reacts nrog ntau lub ntsiab tam sim no nyob rau hauv yaj los tsim cov khoom uas feem ntau insoluble compounds dispersed raws li zoo hais los ntawm cov yaj uas ua raws li ib tug nucleating neeg sawv cev. Boron tsub kom cov khoom siv dag zog thiab txhim kho kev ruaj ntseg sab hauv ntawm tooj dag castings.

50 kg / hnab, sab nraud lub hnab; Los yog hlau nruas packing, 50 kg / nruas, 100 kg / nruas
