继平炉三槽出钢试验成功之后,大冶钢厂为解决平炉——电炉混合炼钢时,钢包中不带入平炉渣问题,试验了“单槽双包出钢”法。此法已于四月中旬试用成功,并已投入生产,正式代替了该厂不久前刚试验成功的双槽出钢设备。单槽双包出钢法是充分利用旧有车间设备,能加倍提高炉产量的一项新措施。大冶钢厂用了此方法,在不增添任何设备条件下,将某号平炉产量提高了100%。虽然这种方法与应用双槽出钢具有同等的意义,但是因为老车间设计的不合理,不一定所有的地势都有可能采用双槽。应用单槽双包出钢法,在任何条件下都能实现。在某种意义上说来,此法给四槽出钢打开了大门。此法还有下述各项特点:1.在同一个炉子上,同时可以冶炼两种不同的钢种,合金钢,炭素钢均可(已试验过的一包为35TL,而另一包可为3号沸腾钢,35钢或5号钢等)。
Following the open hearth three slot tapping test succeeded, Daye Steel to solve the flat hearth - electric furnace mixed steel, the ladle does not bring into the flat slag problem, tested the “single-slot double bag tapping” method. This method was successfully tested in mid-April and has been put into production, officially replaced the plant just recently successfully tested double slot tapping equipment. Single-slot double-bag tapping method is to take full advantage of the old workshop equipment, can double the furnace to increase production of a new measure. Daye Steel used this method to increase the output of a flat hearth furnace by 100% without adding any equipment. Although this method is of equal significance to the application of double trough tapping, it is not always possible to use double troughs for all the terrain because of the unreasonable design of the old workshop. Application of single-slot double bag tapping method, can be achieved under any conditions. In a sense, this method opens the door to the four-slot tapping. The law also has the following characteristics: 1. In the same stove, at the same time can smelt two different types of steel, alloy steel, carbon steel can be (tested one package for 35TL, and the other package For the 3 boiling steel, 35 steel or 5 steel, etc.).
