大中小球墨鑄鐵的焊接2015-07-08dongchang展開全文球墨鑄鐵是在熔煉過程中加入一定量的球化劑，使石墨以球狀存在，從而使力學性能明顯提高。1.球墨鑄鐵的焊接性球墨鑄鐵焊接性與灰鑄鐵有相同的一面，但又有其自身的一些特點。這主要表現(xiàn)在兩方面。(1)球墨鑄鐵的白口化傾向及淬硬傾向比灰鑄鐵大，這是因為球化劑(當其加入量已可穩(wěn)定獲得球狀石墨時)有阻礙石墨化及提高淬硬臨界冷卻速度的作用，所以，在焊接球墨鑄鐵時，同質焊縫及半熔化區(qū)更易形成白口，奧氏體區(qū)更易出現(xiàn)馬氏體組織。(2)由于球鐵的強度、塑性與韌性比灰鑄鐵高，米東區(qū)球墨鑄鐵管聯(lián)系方式，故對焊接接頭的力學性能要求也相應提高，常要求與各強度等級球墨鑄鐵母材相匹配。2.球墨鑄鐵電弧補焊球墨鑄鐵電弧補焊采用同質及異質焊條，同質焊條又有鋼芯與鑄芯之別。異質焊條則采用鎳基焊條(Z408)及高釩焊條，米東區(qū)球墨鑄鐵管聯(lián)系方式，對于不重要的部位也可以采用低碳鋼焊條，如J506，米東區(qū)球墨鑄鐵管聯(lián)系方式、J422等。球墨鑄鐵通常應用于比較重要的場合，采用同質焊條焊接時應保證焊縫球化，力學性能達到規(guī)定的指標，應盡量降低白口傾向，提高抗裂性。(1)Z238焊條電弧熱焊。Z238焊條為低碳鋼焊芯，藥皮中加入球化劑及石墨化劑，在一定工藝條件下，焊縫中的石墨可成為球狀。阿勒泰離心球墨鑄鐵管銷售廠家。米東區(qū)球墨鑄鐵管聯(lián)系方式</p><div

則鐵水中的含鎂量和稀土量降低，造成球化不良或球化衰退等缺點。3.出鐵量。必須聽從配料員的指令，因為球化劑加入量是按出鐵量確定的。鐵水多出，則鐵水中的含鎂量降低，可能造成球化衰退和球化不良。鐵水少出，則鐵水中的含鎂量和稀土量升高，降低了機械性能。4.澆注時間。應嚴格按照工藝要求執(zhí)行。結論：出鐵溫度，球化劑加入量，出鐵量和澆注時間必須嚴格按照工藝要求來執(zhí)行，產(chǎn)品質量才能保證！五.質量檢驗。對每包球化鐵水在澆注完***一型鑄件時，需對該型插棒標識，同時澆注金相試塊，用于檢驗本包鐵水的球化情況。若球化級別為2-3級視為合格。若大于等于4級視為球化衰退，須對本包所澆注的鑄件進行隔離標識。待正常冷卻后，對鑄件斷口逐件檢驗分揀，不合格品報廢回爐使用。</p><p

因此有增大縮孔、縮松產(chǎn)生的傾向。一般工廠控制含磷量小于008%。(3)稀土和鎂：稀土殘余量過高會惡化石墨形狀，降低球化率，因此稀土含量不宜太高。而鎂又是一個強烈穩(wěn)定碳化物的元素，阻礙石墨化。由此可見，殘余鎂量及殘余稀土量會增加球鐵的白口傾向，使石墨膨脹減小，故當它們的含量較高時，亦會增加縮孔、縮松傾向。(4)壁厚：當鑄件表面形成硬殼以后，內部的金屬液溫度越高，液態(tài)收縮就越大，則縮孔、縮松的容積不僅***值增加，其相對值也增加。另外，若壁厚變化太突然，孤立的厚斷面得不到補縮，使產(chǎn)生縮孔縮松傾向增大。(5)溫度：澆注溫度高，有利于補縮，但太高會增加液態(tài)收縮量，對消除縮孔、縮松不利，所以應根據(jù)具體情況合理選擇澆注溫度，一般以1300～1350℃為宜。(6)砂型的緊實度：若砂型的緊實度太低或不均勻，以致澆注后在金屬靜壓力或膨脹力的作用下，產(chǎn)生型腔擴大的現(xiàn)象，致使原來的金屬不夠補縮而導致鑄件產(chǎn)生縮孔縮松。(7)澆冒口及冷鐵：若澆注系統(tǒng)、冒口和冷鐵設置不當，不能保證金屬液順序凝固；另外，冒口的數(shù)量、大小以及與鑄件的連接當否，將影響冒口的補縮效果。(1)控制鐵液成分：保持較高的碳當量(>39%)；盡量降低磷含量(<008%)。米東區(qū)球墨鑄鐵管聯(lián)系方式</p><p
