摘 要:分析本鋼特鋼中棒材頭部彎曲產(chǎn)生的原因,通過優(yōu)化加熱工藝、新增定徑軋制工藝、改進(jìn)出入口導(dǎo)衛(wèi)固定方式與出口導(dǎo)衛(wèi)內(nèi)堂尺寸,有效降低了中棒材頭部彎曲度及彎曲比例,顯著提升鋼材外觀質(zhì)量,減少金屬損失,降低了生產(chǎn)成本。
關(guān)鍵詞:頭部彎曲;加熱;軋機(jī);導(dǎo)衛(wèi);定徑軋制
Abstract:This article analyze the reasons for the bending of the head of the bars in Benxi special steel. By optimizing the heating process, adding a fixed diameter rolling process, improving the fixing method of the inlet and outlet guide and the size of the outlet guide, the bending degree and proportion of the head of the bar have been effectively reduced, significantly improving the appearance quality of the steel, reducing metal loss, and lowering production costs.
Key Words: head bending; heating; rolling mill; guide and guard; fixed diameter rolling
