用偏磷酸盐与硫酸协调处理热网循环水

Gongye shui chuli, 1987
我省现有中压炉发电机组31台;东北地区近200台,总发电量近200万千瓦、煤耗较高压机组高1/3。如低压机组改为低真空运行冷却水供热、煤耗将降至高压机组水平。虽然国内冷却水采用偏磷酸盐处理已有很多先例,但汽轮机凝汽器低真空运行,冷却水处理此法还没有人用过。由于热网水运行温度一般为60±5℃,全部循环系统是封闭的,与大气隔绝,因此它与一般冷却水的水质特性运行工况是不同的。

冷却速度对真空电弧熔炼CuCr25合金组织及性能的影响

Gaoya dianqi, 1999
采用真空电弧熔炼法制备CuCr25合金,随合金凝固时的冷却速度不同,合金的组织将发生很大变化,而不同组织对合金的性能特别是电击穿性能将产生不同的影响,必须选用一种最合适的冷却方式对熔炼后的合金进行冷却凝固.通过对不同冷却方式下合金的组织变化及其对耐电压强度影响的研究,确定水冷凝固法作为真空电弧熔炼CuCr25合金的主要冷却方式.
