鋼材理論重量計(jì)算的計(jì)量單位為公斤( kg )。其基本公式為:
W (重量, kg ) = F (斷面積 mm2 )× L (長度, m )×ρ(密度, g/cm3 )× 1/1000鋼的密度為: 7.85g/cm3 ,各種鋼材理論重量計(jì)算公式如下: 名稱(單位) 計(jì)算公式 符號意義 計(jì)算舉例 等邊角鋼(kg/m)
W= 0.00785 ×[d (2b ?C d )+0.215 (R2 ?C 2r 2 )]
b= 邊寬d= 邊厚R= 內(nèi)弧半徑r= 端弧半徑
求 20 mm × 4mm 等邊角鋼的每m 重量。從冶金產(chǎn)品目錄中查出 4mm × 20 mm 等邊角鋼的R 為3.5 ,r 為1.2 ,則每m 重量= 0.00785 ×[4 ×(2 ×20 ?C 4 )+0.215 ×(3.52 ?C 2 ×1.2 2 )]= 1.15kg
