德国曼内斯曼迪马克冶金技术公司开发了一种生产不锈钢的三联工艺,即:EAF(电弧炉)-MRP-L(使用氧枪的金属精炼转炉)—VOD(真空吹氧脱碳装置)。这套工艺和设备已于1988年4月在比利时的ALZ厂投产。其电弧炉、转炉和VOD装置的出钢量分别为85t、100t和100t。在该工艺路线中,偏心炉底出钢型电弧炉仅用作熔化装置,从出钢到出钢的时间为75min。MRP-L转炉主要用作快速脱碳装置,它配有2支可移动式氧枪,1根为工作
Mannesmann, Germany Mandemark Metallurgical Technology has developed a triple stainless steel production process: EAF (electric arc furnace) - MRP-L (metal refining furnace with oxygen lance) - VOD (vacuum oxygen blowing decarburization unit) . The process and equipment were put into operation at the ALZ plant in Belgium in April 1988. The tapping capacity of the electric arc furnace, converter and VOD unit is 85t, 100t and 100t respectively. In the process route, eccentric hearth tapping type electric arc furnace is only used as a melting device, from tapping to tapping time is 75min. MRP-L converter is mainly used as a fast decarburization device, it is equipped with two portable oxygen lance, a work for
