摘要I摘要加熱爐是將物料或者工件加熱的設(shè)備。在冶金工業(yè)中加熱爐習(xí)慣上指把金屬加熱到軋制成鍛造溫度的工業(yè)爐。步進(jìn)梁式再加熱爐是連軋生產(chǎn)線提供鋼管再加熱所有。它是依靠專用的步進(jìn)機(jī)械使工件在爐內(nèi)移動(dòng)的一種機(jī)械化爐子。步進(jìn)梁式加熱爐設(shè)計(jì)一種連續(xù)式加熱爐它是靠專用的步進(jìn)機(jī)構(gòu)，按照一定的軌跡運(yùn)動(dòng)，使?fàn)t內(nèi)鋼料一步一步地向前推進(jìn)。步進(jìn)梁式加熱爐爐底的結(jié)構(gòu)和傳動(dòng)方式要根據(jù)出料的頻率和爐子的生產(chǎn)能力決定，它要考慮被加工工件的尺寸參數(shù)和工地方面的尺寸大小。所以必須嚴(yán)格計(jì)算其內(nèi)部參數(shù)，保證爐子的生產(chǎn)和安全。爐底機(jī)械采用雙輪斜軌機(jī)構(gòu)。步進(jìn)梁的升降和平移動(dòng)作采用液壓缸驅(qū)動(dòng)。加熱爐爐床由固定梁和步進(jìn)梁兩部分組成，步進(jìn)梁由雙重輪對的多軸框架支撐，其外側(cè)走輪由液壓缸驅(qū)動(dòng)，可以在傾斜軌道上滾動(dòng)，使步進(jìn)梁作上升或者下降運(yùn)動(dòng)。上層托輪直接拖住步進(jìn)梁，而步進(jìn)梁則由另兩個(gè)液壓缸帶動(dòng)，實(shí)現(xiàn)平移運(yùn)動(dòng)。關(guān)鍵詞：步進(jìn)梁式加熱爐；步進(jìn)梁；雙輪斜軌式機(jī)構(gòu)；液壓傳動(dòng)AbstractIIAbstractHeatingfurnaceisthematerialorworkpieceheatingequipment.Inthemetallurgicalindustryinthemetaltoheatinghabitsheatedtorolledintotheindustrialfurnacetemperatureforging.Walkingbeamtypefurnaceisprovidedtosteelrollinglineheatingallagain.Itdependonspecialsteppingmachinerytomaketheworkinthefurnacestoveamechanizedmoving.Steppingbeamfurnacedesignacontinuousreheatingfurnaceofitistorelyonspecialsteppinginstitutions,accordingtocertaintrajectory,makingfurnaceofsteelmaterialwithinstepforward.Stepreheatingfurnacebottomstructureanddrivingmodeaccordingtothematerialofthefrequencyandtheproductioncapacityofthestove,itshouldconsiderdecisionbythesizeofthemachiningparametersandthesiteofsize.Somuststrictlycalculationitsinternalparameters,guaranteetheproductionandthestovesafety.Furnacebottommachineadoptsdoubleinclinedrailagencies.Theriseandfallofwalkingbeambyhydrauliccylinderforpeacemovementdriven.Heatingfurnacebedbyfixedgirdersandwalkingbeamtwoparts,walkingbeamofbydoubleroundmultiaxialframework,thelateralgoroundsupportedbyhydrauliccylinderdrive,cantiltorbitinrollingmakewalkingbeamriseorfallassport.Theupperrollerdirecttuggedwalkingbeam,andwalkingbeamisdrivenbytwootherhydrauliccylinder,realizetheshiftmovement.KeyWords：steppingbeamfurnace，walkingbeam，monrailagencies，hydraulictransmission目錄III目錄摘要.IAbstract.II1緒論.11.1步進(jìn)式加熱爐.11.1.1步進(jìn)式加熱爐概述.11.1.2選題背景.41.1.3設(shè)計(jì)目的.51.1.4設(shè)計(jì)方案.72液壓系統(tǒng)分析與設(shè)計(jì).92.1運(yùn)動(dòng)與負(fù)載分析.92.1.1步進(jìn)式加熱爐原始數(shù)據(jù).92.1.2步進(jìn)式加熱爐工況速度曲線設(shè)計(jì).92.1.3計(jì)算穩(wěn)態(tài)工作負(fù)載.112.1.4擬定液壓原理圖.122.2液壓缸參數(shù)及其型號(hào).132.2.1平移液壓缸受力分析.132.2.2初選平移液壓系統(tǒng)工作壓力.142.2.3平移液壓缸主要參數(shù)及其選取型號(hào).142.2.4升降液壓缸受力分析.162.2.5初選升降液壓系統(tǒng)工作壓力.182.2.6升降液壓缸主要參數(shù)及其選取型號(hào).182.3液壓泵參數(shù)及其型號(hào).192.3.1平移液壓泵工作壓力的確定.192.3.2平移液壓泵流量的確定.192.3.3平移液壓泵的選取.202.3.4升降液壓泵工作壓力的確定.202.3.5升降液壓泵流量的確定.20目錄IV2.3.6升降液壓泵的選取.202.4電動(dòng)機(jī)參數(shù)及其型號(hào).212.4.1平移液壓系統(tǒng)電動(dòng)機(jī)參數(shù)及其型號(hào).212.4.2升降液壓系統(tǒng)電動(dòng)機(jī)參數(shù)及其型號(hào).212.5液壓閥件參數(shù)及其型號(hào).222.5.1平移液壓系統(tǒng)閥件參數(shù)及其型號(hào).222.5.2升降液壓系統(tǒng)閥件參數(shù)及其型號(hào).222.6液壓油管道的選擇.222.6.1油管的選用.222.6.2液壓油管管徑的確定.232.6.3液壓油管管壁厚的驗(yàn)算.232.7液壓油管道的選擇.242.7.1平移液壓系統(tǒng)油箱有效容積.242.7.2升降液壓系統(tǒng)油箱有效容積.243液壓系統(tǒng)性能驗(yàn)算.253.1液壓系統(tǒng)壓力損失計(jì)算.253.1.1平移液壓系統(tǒng)壓力損失.253.1.2升降液壓系統(tǒng)壓力損失.263.2液壓系統(tǒng)發(fā)熱溫升計(jì)算.263.2.1
