濟(jì)鋼一級(jí)代理商在加熱時(shí)工件表面附著油,油附著部位的氧化皮厚度和其他部分的氧化皮厚度和組成就不同,而且會(huì)產(chǎn)生滲碳。氧化皮下基體金屬被滲碳的部分將嚴(yán)重地受到酸的侵蝕。重油燒嘴最初燃燒時(shí)所噴出的油滴,若附著在工件上,影響也很大。
When the heater is heated, the surface of the workpiece is adhered with oil, the thickness of the oxide skin and the thickness and composition of the oxide parts of the oil attached parts are different, and carburizing is produced. The part of the metal that is oxidized beneath the base shall be badly eroded by acids. The oil droplets ejected from the heavy oil burner at the initial combustion have great impact if attached to the workpiece.
工件表面如有冷加工時(shí)附著的潤(rùn)滑油等,必須在三氯乙烯脫脂劑、苛性鈉溶液中充分脫脂后再用溫水清洗,然后再進(jìn)行熱處理。不銹鋼如果表面有雜物,特別是有機(jī)物或灰附著工件上時(shí),加熱當(dāng)然會(huì)對(duì)氧化皮有影響。

Attachment of cold processing such as workpiece surface lubrication oil, must be fully skimmed in trichloroethylene degreasing agent, caustic soda solution and then with warm water washing, and then heat treatment. Stainless steel, if the surface of debris, especially organic matter or ash attached to the workpiece, heating, of course, will affect the oxide skin.
不銹鋼爐內(nèi)氣氛的差異爐內(nèi)氣氛在各局部的不同,氧化皮的形成一也會(huì)有變化,這也是造成酸洗后不均勻的原因。所以,在加熱時(shí),爐內(nèi)各部位的氣氛必須相同。
The difference of the atmosphere in the stainless steel furnace, the atmosphere in the furnace in different parts, the formation of oxide skin will change, and this is also caused by uneven acid cleaning reasons. Therefore, when heating, the atmosphere in each part of the furnace must be the same.
濟(jì)鋼一級(jí)代理商與加熱工件直接接觸的物體,必須經(jīng)過(guò)充分烘干才能使用。但是,烘干后如在常溫下放置,在濕度高的情況下,水分仍會(huì)凝聚在工件表面上。所以,最好是在使用前烘干。
The first level agent of Jinan Iron and steel company must be fully dried before it can be used directly with the heating workpiece. However, after drying, such as placed at room temperature, moisture in high conditions, the water will still condense on the surface of the workpiece. So, it's better to dry before use.
公司始終堅(jiān)持不斷進(jìn)行管理創(chuàng)新和科研創(chuàng)新,將以?xún)?yōu)良的品質(zhì)、完善的售后服務(wù)贏得廣大客戶(hù)的信賴(lài)與支持,歡迎廣大新老客戶(hù)來(lái)我公司實(shí)地考察,洽談合作！
