节能型养护窑已在全国20多家工厂推广使用。这些工厂虽然生产规模不一,但一致反映技术经济效益显著,较之坑养、空腔内直通蒸汽养护优越。使用结果表明,它确有如下优点。一、窑的保温性能好由于采用了新型窑体形式、新的保温结构和新式的卷帘门等措施,大大减少了蒸汽漏损,缩短了供汽时间.窑的保温性能好,测试表明:当窑温为90℃左右时,窑外壁与窑顶表面的温度与气温的温差仅为1～2℃;停汽5小时后,窑温基本不降。二、窑内温度分布均匀,热交换条件好三、缩短养护时间,加速钢模周转不论养护短杆还是长杆,养护周期均能稳定在5小时以内,有些厂家仅用4小时。
Energy-saving maintenance kiln has been promoted in more than 20 factories across the country. Although the production scales of these plants are different, they all reflect the significant technical and economic benefits, and are superior to the pit maintenance and through-hole steam maintenance. The results show that it does have the following advantages. First, the kiln insulation performance is good due to the use of a new type of kiln, new insulation structure and the new type of shutter doors and other measures to greatly reduce the steam leakage, shortened the time of steam supply. The kiln insulation performance is good, the test shows that: When the kiln When the temperature is about 90°C, the temperature difference between the temperature of the outer wall of the kiln and the surface of the kiln and the temperature of the kiln is only 1 to 2°C; after the steam is stopped for 5 hours, the kiln temperature does not decrease substantially. Second, the kiln temperature distribution, heat exchange conditions are good Third, to shorten the curing time, speed up the steel mold regardless of maintenance short rod or long rod, the maintenance cycle can be stable within 5 hours, some manufacturers only use 4 hours.
