作為這個問題的解決方案,建議使用粘度高、結(jié)晶溫度低的保護(hù)渣。保護(hù)渣的密度和表面張力影響爐渣的乳化行為,但在實(shí)際操作中,即使渣化學(xué)成分變化,這些性質(zhì)也不會有太大的改變。漩渦的卷渣機(jī)理可分為兩種不同的模式,即有初始渦量時出現(xiàn)的vortex-sink和在沒有初始渦量時發(fā)生的造成澆鑄后期卷渣的draiHsink。雖然經(jīng)常說vortex-sink可以忽略而drain-sink才是爐渣乳化的主因,但仍有些人主張,至少在部分程度上,卷渣要?dú)w因于vortex-sink。

人們所熟悉的“泵”是一種能提高位能的機(jī)械設(shè)備,比如水泵主要是提高水位或增加水壓,而“熱泵”是一種能從自然界的空氣、水或土壤中獲取低位熱,經(jīng)過電力做功,輸出可被人們所用的高品位熱的設(shè)備,是一種節(jié)能、環(huán)保、清潔的采暖和熱水設(shè)備,熱泵技術(shù)是近年來在全世界倍受關(guān)注的新能源技術(shù)。如何理解“熱泵”?舉個簡單的例子,汽車耗幾升汽油就可以把幾噸貨物從一個地方運(yùn)到另一個地方,熱泵機(jī)組可從自然界中吸收熱量經(jīng)過熱泵的“搬運(yùn)”(電力做功驅(qū)動熱泵),獲得可用于生產(chǎn)、生活的熱能。

不銹鋼工件放置于空氣中會形成氧化膜,但這種膜的保護(hù)性不夠完善。通常先要進(jìn)行清洗,包括堿洗與酸洗,再用氧化劑鈍化,才能保證鈍化膜的完整性與穩(wěn)定性。酸洗的目的之一是為鈍化處理創(chuàng)造有利條件,保證形成優(yōu)質(zhì)的鈍化膜。因?yàn)橥ㄟ^酸洗使不銹鋼表面平均有1μm厚一層表面被腐蝕掉,酸液的化學(xué)活性使得缺陷部位的溶解率比表面上其它部位高,因此酸洗可使整個表面趨于均勻平衡,一些原來容易造成腐蝕的隱患被清除掉了。但更重要的是,通過酸洗鈍化,使鐵與鐵的氧化物比鉻與鉻的氧化物優(yōu)先溶解,去掉了貧鉻層,造成鉻在不銹鋼表面富集,這種富鉻鈍化膜的電位可達(dá)+1.V(SCE),接近貴金屬的電位,提高了抗腐蝕的穩(wěn)定性。
