为提高电功机车产品质量,满足转向架构架焊接后进行整体加工消除内应力的工艺要求,在已进行模拟试验并取得必要数据的基础上,设计了一台大型全硅酸铝纤维罩式电阻炉(外形见图),于一九八六年五月正式投产。该炉炉膛尺寸为7.4×3.27×1.5(米~3),配置功率240千瓦,最高炉温600℃,电控柜采用可控硅过零脉冲调节,可按工艺要求进行程序控制。炉子投产后对提高产品质量及节约能源取得较显著的效益: 1.提高构架制造质最,减少或消除了
In order to improve the product quality of electric locomotives and meet the process requirements of integral process to eliminate internal stress after the bogie frame is welded, a large all-aluminum silicate fiber shroud resistor has been designed based on the simulation test and the necessary data obtained. Furnace (see picture), in May 1986 formally put into operation. The furnace hearth size of 7.4 × 3.27 × 1.5 (m ~ 3), configuration power of 240 kW, the maximum furnace temperature of 600 ℃, SCR cabinet with zero-crossing pulse adjustment, according to process requirements for program control. Stove put into operation to improve product quality and save energy to achieve more significant benefits: 1. To enhance the quality of the framework of the manufacture, reduce or eliminate
