去年我厂生产了数十台HG6/13—1型锅炉,其中炉排部件包括:有缝炉排,每台300件,每件毛重4.3公斤;边炉排,每台40件,每件毛重4公斤;薄片炉排,每台48件,每件毛重0.5公斤;总计每台重1474公斤。采用RQTSi—4.5,RQTSi—5.5两种含硅耐热球铁。锅炉发货后,大部分用户反映良好,个别用户则反映有断裂情况,例如:盘锦九化公司的锅炉在使用约140个小时后,炉排片断裂300多块。哈尔滨印染厂的锅炉在使用约1440小时后,炉排片断裂60多块。而且都是在位于750～800℃温度场的主燃区炉排片断裂最多。断
Last year, our factory produced dozens of HG6 / 13-1 boilers, of which the grate components include: Grate with each, 300 pieces, each weighing 4.3 kilograms; side grate, each 40, each gross weight 4 kg; sheet grate, each 48, each 0.5 kg gross weight; total weight of 1474 kg each. Using RQTSi-4.5, RQTSi-5.5 two heat-resistant ductile iron containing silicon. After the boiler was delivered, the majority of users responded well, and individual users reflected the breakage. For example, after about 140 hours of operation of the boiler at Panjin Nineu Company, the grate rupture was over 300 pieces. Harbin printing and dyeing plant boiler in use for about 1440 hours after the grate break more than 60 pieces. Moreover, the rupture of the grate rupture in the main combustion zone at the temperature of 750-800 ℃ is the most. Off
