摘　　要：研究了CSP热轧SPHC单张板和板卷的氧化皮厚度,并与传统热连轧产品进行了比较。研究发现,从CSP板卷宽度中心至边部氧化皮厚度逐渐增加,且中心到1/4宽处的增加趋势比1/4宽到边部的强;单张板的氧化皮比板卷的厚;下表面的氧化皮比上表面的厚;CSP板卷厚度(h)与氧化皮厚度(x)间呈x=3.956 95+2.096 07h关系,而传统热连轧产品则呈x=8.152+3.132h;CSP板卷的氧化皮较传统热连轧的薄,其厚度对板厚也不太敏感。应以板卷下表面的氧化皮性状作为制定酸洗工艺的基础。The scale thickness distribution on SPHC strip rolled by CSP process is investigated and compared with that by traditional hot rolling mill. The following results are obtained： the scale thickness increases from width center to edge of strip, however the increasing tendency from center to quarter is stronger than that from quarter to edge; the scale on hot coiled strip is thicker than on cooled coil; the scale on bottom side of strip is thicker than on upper side; the relation of scale thickness x with strip thickness h is expressed as： x = 3. 956 95＋2. 096 07 h and x= 8. 152 ＋ 3. 132 h for coil produced by CSP and traditional hot rolling mill respectively; the thickness of scale on CSP rolled coil is thinner and less sensitive to strip thickness . Thus the pickling process should be worked out based on the characteristics of scale on strip bottom side.
