我厂于1989年建成一台罩式旋压封头退火炉,功率为288千瓦,这个炉子有下列特点:结构合理,造价便宜,属非系列产品。加热工件最大尺寸约为(?)5700毫米。经过3年的使用,效果非常好,热效率达50%以上。现就将其特点具体叙述如下:1 炉子结构在我们自行设计以前,曾做了一些调研和招标,某设计院报价为:如用煤做燃料需60万元,如用电则需80万元,而我们采用这个结构(如图1所示),全部费用只用了30万元。此结构主要考虑到封头的形状,还根据产量少(平均一班一炉),加热时间长,加热温度不超过950℃,我们不用耐火材料复合保温而直接用一层保温材料硅酸铝纤维,这样不
I plant in 1989 to build a hood spin-head annealing furnace, a power of 288 kilowatts, the stove has the following characteristics: a reasonable structure, low cost, is a non-series products. The maximum size of the heated workpiece is about (?) 5700 mm. After 3 years of use, the effect is very good, thermal efficiency of more than 50%. Now its characteristics are described as follows: 1 furnace structure Before our own design, had done some research and bidding, a design institute quoted as: If you need to use coal to fuel 600,000 yuan, such as electricity will need 800,000 yuan , And we use this structure (shown in Figure 1), the total cost of only 300,000 yuan. This structure mainly takes into account the shape of the head, but also less output (an average of a furnace), the heating time is long, the heating temperature does not exceed 950 ℃, we do not have refractory composite insulation directly with a layer of insulation material aluminum silicate fiber So no
