為什么冷拔方鋼制造容易出現(xiàn)表面裂紋現(xiàn)象？1、裂紋假如是由于鋼中夾雜物未進(jìn)行處理而導(dǎo)致的。這就要選用合理的脫氧合金化工藝，嚴(yán)格控制鋼水含氧量，降低鋼水夾雜物的含量。2、假如裂紋是由外表折疊引起的。那么就要合理規(guī)劃孔型，消除成品前軋件的耳子;準(zhǔn)確規(guī)劃寬展，調(diào)輥槽方位，減輕或消除飛邊、刮傷等缺點(diǎn)。3、若是由皮下氣泡引起的裂紋。那就要注意全程保護(hù)澆筑進(jìn)程，防止鋼水二次氧化，削減氣泡發(fā)生，進(jìn)步鑄坯的純度;合理控制連鑄鋼水過熱度，選擇理化功能優(yōu)良的保護(hù)渣，采納均勻冷卻和二次弱冷卻，防止鑄坯外表出現(xiàn)裂紋。

冷拉鋼市場政策的明朗，工地開工大幅增多，永鋼需求明顯回升，冷拉鋼成交量快速攀升，從而抬高貿(mào)易商推漲熱情。其次，前期，建筑鋼材較其他鋼材品種跌幅更大，跌速更快，建筑鋼材價(jià)格基本已經(jīng)跌破近3年多以來的歷史低點(diǎn)，行情上有超跌反彈的內(nèi)在因素。再次，鋼廠方面，尤其是中小鋼廠，3月中旬前多數(shù)處于減產(chǎn)或者限產(chǎn)的狀態(tài)，市場供應(yīng)偏緊，造成部分資源規(guī)格斷檔的情況出現(xiàn)，刺激市場價(jià)格反彈。而板材市場方面，由于下游終端需求釋放較慢，市場庫存高企，加上近期熱軋板卷期貨新上市，對市場造成不小的利空影響，板材價(jià)格陷入震蕩盤整的狀態(tài)，未能出現(xiàn)明顯回升。但整體市場與前期相比，出貨量有所好轉(zhuǎn)，市場趨于穩(wěn)定。雖然長期鐵礦石需求增速將受制，但至少從一季度下游冷拉鋼市場結(jié)構(gòu)表現(xiàn)來看，暫未出現(xiàn)長期受控制或下滑的確定性跡象?！昂笃诮ㄗh投資者關(guān)注下游鋼材去庫存，及鋼企回補(bǔ)庫存和港口庫存消化的情況，若上述想象能同時(shí)進(jìn)行，則二季度短時(shí)間內(nèi)鐵礦石價(jià)格存在一定幅度反彈的機(jī)會(huì)?！毙锣l(xiāng)康宏機(jī)械公司生產(chǎn)的冷拔鋼質(zhì)量好。</p><div
