黄先禄(重庆铁合金厂)报道:根据GB3869—83《体力劳动强度分级》,作者于1988~1989年对铁合金作业的矽铁、矽钙、锰铁、铬铁冶炼工,产品精整工,冶炼行车工,配电工,配料工等,进行了体力劳动强度分级调查。铁合金作业劳动时间率为11.8~69.8%,平均31.8%,工作日能量代谢率7.87KJ/min·m~2,工作日能量总消耗5827KJ。劳动强度Ⅲ级占4.5%,Ⅱ级占27.3%,Ⅰ级占68.2%。铁合金作业冶炼工劳动时间率为24%,能
Huang Xianlu (Chongqing ferroalloy plant) reported: According to GB3869-83 “manual strength classification”, the author in 1988 ~ 1989 on ferroalloy operations of ferrosilicon, calcium silicate, ferromanganese, ferrochromium smelter, product finishing, smelting traffic Workers, power distribution workers, ingredients workers, conducted a manual classification of physical strength. Ferroalloy working time rate of 11.8 ~ 69.8%, an average of 31.8%, workday energy metabolism rate of 7.87KJ / min · m ~ 2, the total energy consumption of 5827KJ working day. Class Ⅲ labor intensity accounted for 4.5%, Ⅱ grade accounted for 27.3%, Ⅰ grade accounted for 68.2%. Ferroalloy smelter labor time rate of 24%, can
