焦炭反應性測定試驗制樣系統能滿足的標準(zhun)：

GB/T4000-2008《焦炭反(fan)應性及反(fan)應后強度試驗方(fang)法》

GB/T1997-2008《焦炭試樣(yang)的采取(qu)和制備(bei)》

本系統(tong)適用于焦炭反應(ying)性及反應(ying)后(hou)強度的試(shi)樣制(zhi)樣參數技術要求、結果評定等(deng)。

本系(xi)統構成：

1、HXPY-A焦炭顆粒破(po)樣機

2、HXZY-B焦炭顆粒制球機

3、HXMY-C焦(jiao)炭制(zhi)樣磨樣機

注：客戶單位(wei)可(ke)根據自身需求，可(ke)單獨購置HXZY-B焦炭顆粒制球(qiu)機，也(ye)能完成基(ji)本制樣(yang)要求。

焦炭反應性測定試驗制樣系統操作過程(cheng)（以下數據供參(can)考）：

1、取直徑25-80mm焦(jiao)炭10kg，用HXPY-A焦(jiao)炭顆(ke)粒(li)破樣機(ji)破樣成不等(deng)形(xing)狀的焦(jiao)炭。經破樣篩分(fen)得出，直徑25mm以上(shang)的焦(jiao)炭7.12kg，直徑23-25mm的焦(jiao)炭0.25kg，直徑23mm以下的2.63kg。

2、將直(zhi)(zhi)徑(jing)25mm以(yi)上的(de)焦炭逐(zhu)個放入模口上，然(ran)后(hou)關(guan)上蓋板，用HXZY-B焦炭顆粒制(zhi)球(qiu)機進行(xing)制(zhi)樣，沖制(zhi)好的(de)焦炭與碎沫(mo)會分(fen)級(ji)落入存樣箱。共制(zhi)球(qiu)樣330次，耗時60分(fen)鐘，成形(xing)顆粒280粒，直(zhi)(zhi)徑(jing)25mm以(yi)上20顆，重(zhong)(zhong)量170g；直(zhi)(zhi)徑(jing)23-25mm的(de)228顆，重(zhong)(zhong)量1.7公斤(jin)，經轉(zhuan)鼓(gu)試驗(yan)后(hou)23-25mm顆粒221，重(zhong)(zhong)量為1.64kg，共221顆，其中(zhong)直(zhi)(zhi)徑(jing)23以(yi)下(xia)32顆，重(zhong)(zhong)量170克。按國(guo)標要求23-25mm可用的(de)焦炭樣196顆，重(zhong)(zhong)約1.47kg。

3、用HXMY-C焦炭制樣磨(mo)樣機對樣品充分打磨(mo)使其接近于球形。

HXPY-A焦炭顆粒破樣機(ji)技術(shu)參數：

HXZY-B焦炭顆粒制球機(ji)技術參數：

HXMY-C焦炭制樣(yang)磨樣(yang)機(ji)技術(shu)參數：

經多家鋼鐵公司焦(jiao)炭(tan)(tan)質檢站、焦(jiao)炭(tan)(tan)質檢中(zhong)(zhong)心（實驗室）技術中(zhong)(zhong)心反(fan)復實踐證實，用10kg的焦(jiao)炭(tan)(tan)經本系統制(zhi)樣(yang)(yang)后，能制(zhi)成(cheng)符合國標要求的焦(jiao)炭(tan)(tan)樣(yang)(yang)品(pin)有1.47kg左右(you)，能為焦(jiao)炭(tan)(tan)反(fan)應性試(shi)驗提供5個(ge)試(shi)驗樣(yang)(yang)以(yi)上。該系統大(da)大(da)提高了焦(jiao)炭(tan)(tan)的利用率，減(jian)少了勞動強度和污(wu)染，節省(sheng)了制(zhi)樣(yang)(yang)時(shi)間，提高經濟效(xiao)益。
