随着生产大跃进和球墨鑄鉄件数量的增加,高温燜火窑就远不能滿足生产的需要。在这种情况下,我厂清鏟工段烤窑組工人发揮了敢想敢干的精神,創造了用土燜火窑来进行高温燜火。目前鑄工車間所有高温燜火件已有80％以上用土窑来进行处理。土窖的构造和操作工艺土窑的构造如附图,窑身四壁用旧耐火砖砌成,高度有七块边砖高,窑底鋪一层耐火砖,也可用紅砖代替,砖与砖之間相隔70～80公厘,以便爐气流通。土爐外壁用旧耐火砖叠成的花墙,
With the production of the Great Leap Forward and the increase in the number of ductile castings, high temperature brazing furnace can not meet the production needs. In this case, I plant Shovel section Baking kiln group of workers to play a dare to dare to do the spirit, and created a soil simmer furnace for high temperature Braised fire. At present, all high-temperature simmer fire casting workshop has been used for more than 80% of the kiln for processing. Construction and operation of the crypt The structure of the kiln as shown in the attached figure, the kiln body walls are made of old refractory bricks, height of seven bricks high, kiln bottom shop a layer of refractory bricks, red brick can also be used instead, bricks and 70 to 80 mm apart between the bricks, so that furnace gas circulation. Oven wall with old refractory brick stacked into the flower wall,
