Awọn ohun elo:

Ti a lo fun alurinmorin ti iru irin alagbara ti ko ni igbona ti n ṣiṣẹ labẹ awọn ipo iwọn otutu giga, ati tun fun alurinmorin ti awọn irin chrome lile (bii Cr5Mo, Cr9Mo, Cr13, Cr28 ati bẹbẹ lọ) ati awọn irin ti o yatọ.

Awọn abuda:

E310-16jẹ elekiturodu irin alagbara Cr26Ni21 fun ohun elo titẹ awọ rutile.Mejeeji AC ati DC le ṣee lo fun gbogbo alurinmorin ipo.Eleyi elekiturodu ni o ni ti o dara alurinmorin ilana išẹ, ati awọn nile irin ni o ni o tayọ ifoyina resistance labẹ 900-1100 ℃ ga otutu ipo.

AKIYESI:

1. Ṣaaju ki o to alurinmorin, awọn elekiturodu yoo wa ni ndin ni 300-350 ℃ fun 1 wakati ati ki o lo bi ti nilo.
2. Yọ ipata, girisi, ọrinrin ati awọn impurities miiran ṣaaju ki o to alurinmorin.
3. DC ipese agbara ti wa ni niyanju, nitori awọn ijinle ti isiyi alurinmorin jẹ jo aijinile, awọn ti isiyi yẹ ki o ko ni le ju tobi, ki lati yago fun Pupa ati wo inu ti awọn ara.
4. Din awọn ooru input bi Elo bi o ti ṣee, ati awọn golifu titobi ti awọn elekiturodu ko yẹ ki o wa ni tobi ju.
5. Preheat ki o si pa awọn iwọn otutu laarin awọn ikanni ni isalẹ 150 ℃.
