耐高溫不等邊角鋼理論重量計算
鋼材理論重量計算的計量單位為公斤( 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算公式如下: 名稱(單位) 計算公式 符號意義 計算舉例 不等邊角鋼(kg/m) W= 0.00785 ×[d (B+b ?C d )+0.215 (R2 ?C 2 r 2 )] B= 長邊寬b= 短邊寬d= 邊厚R= 內弧半徑r= 端弧半徑 求 30 mm × 20mm × 4mm 耐高溫不等邊角鋼的每m 重量。從冶金產品目錄中查出30 ×20 ×4 不等邊角鋼的R 為3.5 ,r 為1.2 ,則每m 重量= 0.00785 ×[4 ×(30+20 ?C 4 )+0.215 ×(3.52 ?C 2 ×1.2 2 )]= 1.46kg
