應(yīng)用及前景
播報(bào)編輯工程機(jī)械、礦山機(jī)械、煤礦機(jī)械、環(huán)保機(jī)械、冶金機(jī)械等制造企業(yè)舞鋼合作生產(chǎn)用于挖掘機(jī)、裝載機(jī)、推土機(jī)鏟斗板、刃板、側(cè)刃板、刀片、破碎機(jī)襯板、葉片建設(shè)項(xiàng)目的WNM400約5000余噸。在出口美國(guó)、加拿大、澳洲、印度、歐洲的前景一片看好。已經(jīng)直供歐洲客戶(hù)20000余噸。舞鋼生產(chǎn)技術(shù)領(lǐng)先。舞鋼產(chǎn)品現(xiàn)貨常規(guī)規(guī)格厚度8-100mm，長(zhǎng)寬尺寸以2000*8000與2200*8000居多。
切割方法
播報(bào)編輯冷切割冷切割包括有水射流切割、剪切、鋸切或磨料切割。優(yōu)點(diǎn)：切割熱影響小，防止整個(gè)工件硬度降低，減少切割工件變形。缺點(diǎn)：成本高，只能切割薄板，切割速度慢。熱切割熱切割包括有氧氣燃料火焰切割(以下簡(jiǎn)稱(chēng)“火焰切割”)、等粒子切割和激光切割。優(yōu)點(diǎn)：切割成本低，各地都有加工設(shè)備，可切割厚板，切割速度快。缺點(diǎn)：易降低鋼板硬度、產(chǎn)生裂紋。
火焰切割注意
播報(bào)編輯低速切割避免切割裂紋的方法之一，如果無(wú)法進(jìn)行整板預(yù)熱，也可以采用局部預(yù)熱法代替。使用低速切割防止切割裂紋，其可靠性不如預(yù)熱。本人建議用切割前先對(duì)切割帶（所切工件的四周或者直線）用火焰槍空泡幾趟進(jìn)行預(yù)熱，預(yù)熱溫度達(dá)到100℃為宜。如果切割設(shè)備是雙槍或者多槍的情況下，可以用前面的火焰槍抬高高度，進(jìn)行預(yù)熱，后邊火焰槍進(jìn)行切割，也可以達(dá)到預(yù)熱切割的目的。切割后緩冷無(wú)論對(duì)切割件是否預(yù)熱，鋼板切割后的緩冷都會(huì)有效的降低切割后產(chǎn)生裂紋的風(fēng)險(xiǎn)。如果切割后使其帶有溫?zé)岬墓ぜ逊?，使用隔熱毯將其覆蓋，也可實(shí)現(xiàn)緩冷，緩冷要求冷卻至室溫。切割后加熱對(duì)于耐磨板的切割，切割后立即采取加熱（低溫回火），也可防止切割裂紋的有效方法和措施。鋼板切割后通過(guò)低溫回火處理，可以有效消除切割殘余內(nèi)應(yīng)力。對(duì)于鋼板切割后加熱的方法，也可以采用火焰槍燒、電子加熱毯和加熱爐的加熱方式進(jìn)行切割后的加熱。新手上路成長(zhǎng)任務(wù)編輯入門(mén)編輯規(guī)則本人編輯我有疑問(wèn)內(nèi)容質(zhì)疑在線客服官方貼吧意見(jiàn)反饋投訴建議舉報(bào)不良信息未通過(guò)詞條申訴投訴侵權(quán)信息封禁查詢(xún)與解封?2025?Baidu?使用百度前必讀?|?百科協(xié)議?|?隱私政策?|?百度百科合作平臺(tái)?|?京ICP證030173號(hào)?京公網(wǎng)安備11000002000001號(hào)window.PAGE_DATA= {"lemmaId":320979,"lemmaTitle":"WNM400","lemmaDesc":"舞鋼產(chǎn)高級(jí)別調(diào)質(zhì)型耐磨鋼板","lemmaType":0,"uid":181285676,"uname":"wnm360l","createTime":1272005867,"updateTime":1750032303,"isDefault":0,"isDeleted":0,"rank":1,"extData":{"isBaikeV6":1,"isFrontV6":1,"isSapp":0,"isWaitForPersonal":false,"kpdClassify":[{"id":337502,"name":"工業(yè)產(chǎn)品"}],"lemmaId":3522055,"lemma_id":3522055,"newEditor":1,"origAuditArea":7,"origCommandNo":13001003,"pass_count":24,"subLemmaId":3522055,"uip":"39.72.239.143","updateTime":1750032303,"wapEdit":0},"extFlag":0,"versionId":646685486,"versionUid":6850197039,"versionUname":"余額守護(hù)者","versionCreateTime":1750032301,"catalog":[{"level":1,"title":"簡(jiǎn)介","index":"1","uuid":"gn808bkfca","height":28},{"level":1,"title":"力學(xué)性能","index":"2","uuid":"gn808bkj3f","height":28},{"level":1,"title":"對(duì)照","index":"3","uuid":"gn807higqw","height":28},{"level":1,"title":"應(yīng)用及前景","index":"4","uuid":"gn807uri78","height":28},{"level":1,"title":"切割方法","index":"5","uuid":"gn808bkl0r","height":28},{"level":2,"title":"冷切割","index":"5-1","uuid":"gn808bkl2f","height":21},{"level":2,"title":"熱切割","index":"5-2","uuid":"gn808bkl8u","height":21},{"level":1,"title":"火焰切割注意","index":"6","uuid":"gn808bklef","height":28},{"level":2,"title":"低速切割","index":"6-1","uuid":"gn808bklg0","height":21},{"level":2,"title":"切割后緩冷","index":"6-2","uuid":"gn808bklj6","height":21},{"level":2,"title":"切割后加熱","index":"6-3","uuid":"gn808bklmc","height":21}],"abstract":[],"reference":[{"type":1,"title":"WNM400A舞陽(yáng)WNM400B調(diào)質(zhì)耐磨鋼 ","site":"浙江生意寶網(wǎng)絡(luò)有限公司","publishDate":"2025-06-06","index":1,"uuid":"i2guli4o8q","encodeUrl":"533aYdO6cr3_z3kATPKOy_mhYyzBZNT_u7XRW7VzzqIPmGapB43rFJw979Qz-7lkGwaEs5dvcNcbj6fzDUJC7-oYdOoxRapi3ymrFmCG1Oqzu4hoxsxHpIhDX68Vmam16xg"},{"type":1,"title":"【W(wǎng)NM400A舞鋼調(diào)質(zhì)型耐磨鋼板圖片】WNM400A舞鋼調(diào)質(zhì)型耐磨鋼板圖片大全 -
