摘要:以相似模型實(shí)驗(yàn)理論為基礎(chǔ)，針對(duì)昆鋼125 t復(fù)吹轉(zhuǎn)爐，采用1：10水力學(xué)模型，研究了氧槍槍位、頂吹氣流量和底吹流量對(duì)熔池混勻時(shí)間和噴濺量的影響。結(jié)果表明，使用槍位高度在17cm~21cm；底吹氣體流量在0.75 m3/h ~1.25 m3/h；頂吹氣流量在24 m3/h ~28 m3/h的范圍內(nèi)，混勻時(shí)間較短，且噴濺量較小，很穩(wěn)定，在一個(gè)很小的范圍內(nèi)波動(dòng)。當(dāng)?shù)状禋怏w流量為1.0 m3/h，槍位高度為19cm，頂吹氣流量為28 m3/h時(shí)熔池的攪拌混勻效果最佳，噴濺量最少。 關(guān)鍵詞：頂?shù)讖?fù)吹轉(zhuǎn)爐；水力學(xué)模型；頂?shù)讖?fù)合吹煉；混勻時(shí)間
ABSTRACT:In a similar model experiment theory as a foundation, point to the steel 125 t the combined-blowing hydraulics model converter, use, "QiangQiang bits, top-blown oxygen gas flow and bottom blowing flow to pool the amount of time and blender spillage effect. The results show that using a bit 17cm ~ 21cm; high Bottom blowing gas flow in 0.75 m3 / h ~ 1.25 m3 / h; The gas flow top-blown 24 m3 / h ~ 28 m3 / h, within the scope of the blending in a relatively short time, and spitting quantity is lesser, very stable, in a small range. When the bottom blowing gas flow of 1.0 m3 / h, height is 19cm gun bits for gas flow, top-blown 28 m3 / h molten pool mixing blender when best effect, spitting at least amount.
