1.前言 现行高锰钢铸件的生产工艺,按其工艺流程需进行二次升温加热,即第一次高温冶炼、浇铸和第二次高温淬火。可见,其能源消耗重复。为了合理使用能源,应在高温浇铸(1360～1320℃)之后,待温度下降到1050～1100℃时立即入水淬火。这种操作工艺称为高温铸态直接淬火。这样作比现行淬火工艺减少加热电能450～500度/吨钢。以全国年产高锰钢铸件30万吨计,一年可为国家
1. Preface The current high manganese steel casting production process, according to the process need to be heated for the second heating, that the first high-temperature smelting, casting and the second high-temperature quenching. Can be seen, its energy consumption is repeated. In order to rational use of energy, should be high temperature casting (1360 ~ 1320 ℃), until the temperature dropped to 1050 ~ 1100 ℃ immediately quench the water into. This operation is called high temperature as-cast direct quenching. This is compared with the current quenching process to reduce heating energy 450 ~ 500 degrees / ton of steel. With an annual output of high manganese steel castings 300,000 tons, one year for the country
