1.1 使用說(shuō)明
我公司的HL105、HL801等銅鋅釬料，浸潤(rùn)性好、延伸率大、接頭剪切強(qiáng)度和抗拉強(qiáng)度高。適用于硬質(zhì)合金刀具和釬頭、釬具、截齒等的釬焊。釬焊產(chǎn)品使用壽命長(zhǎng)，能承受大的沖擊載荷和疲勞載荷。
銅鋅釬料可采用浸漬釬焊、感應(yīng)釬焊、氣體火焰釬焊、爐中釬焊等工藝方法，釬焊前須對(duì)母材表面進(jìn)行清除氧化膜、油脂、塵物處理，并充分預(yù)熱。
感應(yīng)釬焊時(shí)，釬料和釬劑要在裝配前安置好，切忌使釬料呈封閉環(huán)，防止釬料本身產(chǎn)生感應(yīng)電流而過(guò)早熔化產(chǎn)生虛焊、缺焊。
鹽浴浸沾釬焊應(yīng)定期對(duì)鹽浴液脫氧并予以調(diào)整成分。
Copper base braze welding material
1 Cu-Zn braze welding material
1.1 Guideline
Cu-Zn braze welding material HL105 and HL801 have good invasion property, extensibility property, shear strength property of joint and strength of extension. They can be used for braze welding of cemented carbide tools, drilling bits and bits. These bits can get long working life, better impact load and fatigue load.
Cu-Zn braze welding materials can use techniques such as dip brazing, induction brazing, flame brazing and furnace brazing, the matrix should be clean up and pre-heating before welding.
Braze welding materials and brazing flux should in place before induction brazing, the braze welding materials must avoid closed hoop in case of generate inductive current to cause quality problems.
Salt-bath brazing techinque should deoxidize the salt liquid and make ajustment for composition.
