已推广使用的粘渣补炉是提高炉龄的一项不可忽视的重要措施,提高了炉子寿命,又降低了耐火材料的消耗。 1. 粘渣补炉工艺我厂转炉由于出钢和装铁均在同一侧进行,炉膛大面损坏十分严重。每个炉役,炉龄达到300炉左右时,需用焦油白云石料进行堆补。而堆补料消耗的数量接近或超过砌炉用砖料的数量。为此研究并制定了粘渣补炉的工艺,以降低堆补料的消耗。 1·1 造好粘终渣造好粘终渣的关键是冶炼后期的操作,应掌握的要点是: (1) 终点温度控制在中上限,而出钢时的温度则用白云石或石灰调在下限。
Has been promoting the use of sticky slag furnace is to improve the furnace an important measure can not be ignored to improve the life of the furnace, but also reduces the consumption of refractory materials. 1 sticky slag make-up process I plant as a result of tapping and iron are on the same side of the furnace surface damage is very serious. Each furnace service, furnace age of about 300 furnaces, the need for tar dolomite heap fill. The amount of heap feed consumption close to or exceed the number of brick materials used in building furnaces. To this end, research and development of slag slag furnace technology to reduce the consumption of heap feed. 1.1 The key to making sticky final slag Good sticking final slag operation is the latter part of smelting. The main points that should be grasped are: (1) the terminal temperature is controlled at the upper limit, and the temperature at tapping is made of dolomite or lime At the lower limit.
