我厂是国内生产6102系列柴油机的大型企业,在铸件的熔化工艺上,应用电弧炉进行快速提温和调质,采用双联作业生产出高质量的柴油机铸件。 1980年初我厂柴油机小批量生产时,选用了HDL-1.5t电弧炉。随着生产规模的增大,1985年应用HKS-1250/10型的矿热炉变压器替换了原电炉变压器。电弧炉采用低电压、大电流、大功率熔炼。电炉的平均工作电流从3000A提高到5000A。为解决短网载流量大,每组铜排由宽厚比为3/100的三根增加到五根,
Our factory is a large-sized enterprise that produces 6102 series diesel engines domestically. In the melting process of castings, the arc furnace is used for rapid temperature raising and quenching and tempering. The dual-operation is used to produce high-quality diesel engine castings. Early 1980 I Diesel small batch production, the selection of HDL-1.5t electric arc furnace. With the increase of production scale, the application of HKS-1250/10 submerged arc furnace transformer was replaced by the original electric furnace transformer in 1985. Electric arc furnace with low voltage, high current, high-power melting. The average operating current of the electric furnace increased from 3000A to 5000A. In order to solve the short network traffic, each group of copper by the aspect ratio of 3/100 of the three to five,
