形成生产性高温的因素很多,如高温炉,其中有熔炼炉、加热炉、烘炉等,有被加热的物体如钢锭和各种铸件,还有生产中使用的各种热熔液和化学工业中的放热等等都会使车间温度增高,形成高温作业。盛夏到来后的露天作业,如建筑、搬运、船坞、农业劳动等,由于受太阳光的辐射及气温的影响,也同样是高温作业。 Many factors form the production of high temperature, such as high temperature furnaces, including smelting furnaces, furnaces, ovens and so on, there are heated objects such as ingots and various castings, as well as the production of various hot melt and chemical industry In the heat and so will make the workshop temperature increased, the formation of high-temperature operation. Open-air operations after the arrival of summer, such as construction, handling, docks, agricultural work, due to the impact of solar radiation and temperature, are also high-temperature operation.
