class="khcont">熱連軋無縫鋼管內(nèi)結(jié)疤缺陷是存在于鋼管內(nèi)表面，類似于黃豆粒大小的凹坑，結(jié)疤內(nèi)大部分有呈灰褐色或灰黑色的異物。內(nèi)結(jié)疤的影響因素有：除氧化物劑、噴吹工藝、芯棒潤滑等因素。下面就隨無縫鋼管廠家小編來看一下如何控制無縫鋼管的內(nèi)表面缺陷： 1、除氧化物劑氧化物要求在芯棒預(yù)穿時處于熔融狀態(tài)。其力度等嚴格要求。 1）除氧化物劑粉末粒度一般要求在16目左右。 2）除氧化物劑中硬脂酸鈉的含量要達到12%以上，以使其能在毛管內(nèi)腔中充分燃燒。 3）根據(jù)毛管內(nèi)表面面積確定除氧化物劑的噴吹量，一般為1.5-2.0g/dm2，不同直徑、長度的毛管噴吹得除氧化物劑量是不同的。 2、噴吹工藝參數(shù) 1）噴吹壓力應(yīng)與毛管直徑、長度相配合，既保證吹掃有力，燃燒充分，又不能有未完全燃燒的除氧化物劑被氣流從毛管內(nèi)吹走。 2）吹掃時間應(yīng)根據(jù)毛管直接、長度進行調(diào)節(jié)，以毛管內(nèi)沒有懸浮的金屬氧化物再被吹出為標準。 3）噴嘴高度應(yīng)根據(jù)毛管直徑進行調(diào)節(jié)，以保證對中良好。每個班次要清理一次噴嘴，長時間停機要拆下噴嘴進行清洗。為保證除氧化物劑在毛管內(nèi)壁均勻吹掃，在噴吹除氧化物劑工位使用選裝裝置，并配以旋轉(zhuǎn)氣壓。 3、芯棒潤滑芯棒潤滑效果不好或芯棒潤滑劑溫度過低，會產(chǎn)生內(nèi)結(jié)疤。為了提高芯棒溫度，可采取只一次冷卻水冷卻的辦法。生產(chǎn)過程中需要嚴格控制芯棒的溫度，保證噴涂潤滑劑前芯棒表面溫度在80-120℃，芯棒溫度不能長時間高于120℃，以保證預(yù)穿前其表面的潤滑劑干燥并致密，操作工應(yīng)經(jīng)常檢查芯棒潤滑狀況。</div><p><img

1）大口徑厚壁鋼管通過外吹環(huán)，其上有一排小孔，通過壓縮(compression)空氣，將大口徑厚壁鋼管多余鋅(zinc)液吹去，獲得光潔外表。 2）在滿足生產(chǎn)(Produce)節(jié)奏下，降低曳出速度，可以控制（control)上鋅(zinc)量，降低鋅耗。 3）內(nèi)吹可除去大口徑厚壁鋼管內(nèi)表面多余的鋅液，獲得光潔的內(nèi)表面，被除去的鋅液形成鋅粉，被回收。 4）水冷槽的溫度（temperature)控制在80℃，冷卻(cooling)水用泵送到冷卻塔(The cooling tower)進行冷卻后進行循環(huán)（continue)使用(use)。無縫鋼管廠家無縫鋼管用途很廣泛。一般用途的無縫鋼管由普通的碳素結(jié)構(gòu)鋼、低合金結(jié)構(gòu)鋼或合金結(jié)構(gòu)鋼軋制，產(chǎn)量多，主要用作輸送流體的管道或結(jié)構(gòu)零件。.2、根據(jù)用途不同分三類供應(yīng)：a、按化學(xué)成分和機械性能供應(yīng)；b、按機械性能供應(yīng)；c、按水壓試驗供應(yīng)。按a、b類供應(yīng)的鋼管，如用于承受液體壓力，也要進行水壓試驗。3、專門用途的無縫管有鍋爐用無縫管、化工電力用，地質(zhì)用無縫鋼管及石油用無縫管等多種。 5）水冷后移出水冷槽，落在檢驗臺架上，檢驗后將漏鍍管放入廢品筐內(nèi)，成品管送入輸出輥（gǔn)道。 6）輸送中經(jīng)過鈍化(Inactivation)液噴淋吹環(huán)成品管，使管表面鈍化，經(jīng)外吹環(huán)后，用壓縮空氣將多余的鈍化液吹除。厚壁無縫鋼管按照斷面形狀，無縫鋼管分圓形和異形兩種，異形管有方形、橢圓形、三角形、六角形、瓜子形、星形、帶翅管多種復(fù)雜形狀。 7)輸送中經(jīng)過鋪設(shè)蒸汽（steam）加熱管(Heating
