耐高温不等边角钢理论重量计算
钢材理论重量计算的计量单位为公斤( kg )。其基本公式为: W (重量, kg ) = F (断面积 mm2 )× L (长度, m )×ρ(密度, g/cm3 )× 1/1000钢的密度为: 7.85g/cm3 ,各种钢材理论重量计算公式如下: 名称(单位) 计算公式 符号意义 计算举例 不等边角钢(kg/m) W= 0.00785 ×[d (B+b ?C d )+0.215 (R2 ?C 2 r 2 )] B= 长边宽b= 短边宽d= 边厚R= 内弧半径r= 端弧半径 求 30 mm × 20mm × 4mm 耐高温不等边角钢的每m 重量。从冶金产品目录中查出30 ×20 ×4 不等边角钢的R 为3.5 ,r 为1.2 ,则每m 重量= 0.00785 ×[4 ×(30+20 ?C 4 )+0.215 ×(3.52 ?C 2 ×1.2 2 )]= 1.46kg
