class="khcont5"><p> GB3087鍋爐管 </p> <p> 1、生產(chǎn)制造方法 </p> <p> 按生產(chǎn)方法不同可分為熱軋管、冷軋管、冷拔管、擠壓管等。 </p> <p> 1.1、熱軋無縫管一般在自動(dòng)軋管機(jī)組上生產(chǎn)。實(shí)心管坯經(jīng)檢查并表面缺陷，截成所需長(zhǎng)度，在管坯穿孔端端面上定心，然后送往加熱爐加熱，在穿孔機(jī)上穿孔。在穿孔同時(shí)不斷旋轉(zhuǎn)和前進(jìn)，在軋輥和頂頭的作用下，管坯內(nèi)部逐漸形成空腔，稱毛管。再送至自動(dòng)軋管機(jī)上繼續(xù)軋制。后經(jīng)均整機(jī)均整壁厚，經(jīng)定徑機(jī)定徑，達(dá)到規(guī)格要求。利用連續(xù)式軋管機(jī)組生產(chǎn)熱軋無縫鋼管是較先進(jìn)的方法。 </p> <p> 1.2、若欲獲得尺寸更小和質(zhì)量更好的無縫管，必須采用冷軋、冷拔或者兩者聯(lián)合的方法。冷軋通常在二輥式軋機(jī)上進(jìn)行，鋼管在變斷面圓孔槽和不動(dòng)的錐形頂頭所組成的環(huán)形孔型中軋制。冷拔通常在0.5～100T的單鏈?zhǔn)交螂p鏈?zhǔn)嚼浒螜C(jī)上進(jìn)行。 </p> <p> 1.3、擠壓法即將加熱好的管坯放在密閉的擠壓圓筒內(nèi)，穿孔棒與擠壓桿一起運(yùn)動(dòng)，使擠壓件從較小的模孔中擠出。此法可生產(chǎn)直徑較小的鋼管。 </p> <p> <br /> 鍋爐管重量公式：[(外徑-壁厚)*壁厚]*0.02466=kg/米（每米的重量）。 </p> <p> </p></div><p><img

抗拉強(qiáng)度 </p> <p> 試樣在拉伸過程中，在拉斷時(shí)所承受的力(Fb)，出以試樣原橫截面積(So)所得的應(yīng)力(σ)，稱為抗拉強(qiáng)度(σb)，單位為N/mm(MPa)。它表示金屬材料在拉力作用下抵抗破壞的能力。計(jì)算公式為: </p> <p> 式中:Fb--試樣拉斷時(shí)所承受的力，N(牛頓); So--試樣原始橫截面積，mm。 </p> <p> 屈服點(diǎn) </p> <p> 具有屈服現(xiàn)象的金屬材料，試樣在拉伸過程中力不增加(保持恒定)仍能繼續(xù)伸長(zhǎng)時(shí)的應(yīng)力，稱屈服點(diǎn)。若力發(fā)生下降時(shí)，則應(yīng)區(qū)分上、下屈服點(diǎn)。屈服點(diǎn)的單位為N/mm(MPa)。 </p> <p> 上屈服點(diǎn)(σsu):試樣發(fā)生屈服而力首次下降前的應(yīng)力; 下屈服點(diǎn)(σsl):當(dāng)不計(jì)初始瞬時(shí)效應(yīng)時(shí)，屈服階段中的小應(yīng)力。 </p> <p> 屈服點(diǎn)的計(jì)算公式為: </p> <p> 式中:Fs--試樣拉伸過程中屈服力(恒定)，N(牛頓)So--試樣原始橫截面積，mm。

</p> <p> 斷面收縮率<br /> 在拉伸試驗(yàn)中，試樣拉斷后其縮徑處橫截面積的縮減量與原始橫截面積的百分比，稱為斷面收縮率。以ψ表示，單位為%。計(jì)算公式如下: </p> <p> 式中:S0--試樣原始橫截面積，mm; S1--試樣拉斷后縮徑處的少橫截面積，mm。 </p> <p> 硬度指標(biāo) </p> <p> 金屬材料抵抗硬的物體壓陷表面的能力，稱為硬度。根據(jù)試驗(yàn)方法和適用范圍不同，硬度又可分為布氏硬度、洛氏硬度、維氏硬度、肖氏硬度、顯微硬度和高溫硬度等。對(duì)于管材一般常用的有布氏、洛氏、維氏硬度三種。 </p> <p> A、布氏硬度(HB) </p> <p>
