电厂钢厂化工数控机床SGMJV-C2AAA2E中惯量旋转型伺服电机
A/D转换器选用TLC83,该芯片工作温度区间为~7℃,属于8位串行控制模数转换器,易于和微处理器接口连接,该器件的分辨率及量化误差是影响温度测量精度的重要原因,以铜-康铜热电偶以及测量放大倍数可知由于分辨率及量化误差而引起的误差不大于.2℃,因此由于放大以及A/D转换而引起的温度测量误差合计不大于.6℃,相对于一般供暖系统的设计温差2℃而言,由于上述原因而引起的误差不大于3%,这一精度是比较高的。

乌克兰方面曾把纯镁脱硫工艺与美国、德国选用的复合镁剂脱硫工艺的技能经济指标进行了比较,比较条件是相同处理1t铁水,铁水原始含硫量为.4%。能够看出,纯镁喷吹比复合镁喷吹其镁的运用率要高1%-15%,而喷吹本钱下降了1.1-1.57美元/t铁水。武钢一炼钢厂平改转投产初期铁水预处理选用的是复合镁喷吹工艺(原工艺),后来又改为纯镁喷吹工艺(新工艺),他们对这两种工艺的比照曾宣布在“22年全国炼钢连铸出产技能会议文集“中(P.64-P,67)。

作者曾对自行车左右曲柄热锻模采用上述工艺经高温115℃加热淬火后,用井式气体渗炭炉66~68℃加入少量甲醇和煤油进行保温。两次回火处理后模具使用寿命成倍提高。高温淬火+低温回火(62~64℃)。对于压陷形式失效的热作模具,可以提高其硬度,提高热强度和耐磨性,用115℃淬火后用62~64℃回火的强刃化处理工艺。作者曾在摩托车零件的精锻模采用次工艺,使用效果较好。模具的耐磨性曾加。
