Single-electrode-stem atmosphere-controllable electroslag furnace for efficient production

Abstract

The invention discloses a single-electrode-stem atmosphere-controllable electroslag furnace for efficient production, and belongs to the technical field of electroslag furnaces. The electroslag furnace solves the technical problems that an electrode stem lifting device of an electroslag furnace in the prior art adopts two groups of mechanisms to switch consumable electrodes to work, so that the temperature is difficult to control at the same level as before after the temperature changes in the switching process, and the quality level of produced steel ingots is reduced. The electroslag furnacecomprises an electrode stem rotating device, the electrode stem rotating device is connected with an electrode stem lifting device, an electrode stem lifting frame is arranged outside the electrode stem lifting device in a covering mode, an electric brush device is installed on the electrode stem lifting device, a crystallizer is installed below the electrode stem lifting device, the upper end ofthe crystallizer is covered with an atmosphere protection cover, and the lower portion of the crystallizer is sequentially connected with a bottom water tank and a double-layer trolley adjusting device. According to the electroslag furnace, the step of electrode switching is omitted, the whole production process is continuously carried out without power failure, the temperature is constant, the texture uniformity of the steel ingot is effectively guaranteed, and the product quality and the working efficiency are improved.

Problems solved by technology

This patents describes different methods or techniques for producing special steels with improved performance compared to existing ones. These processes involve improving material utilization rates while reducing costs and enhancing productivity. Additionally, they aim to provide stable electric current conduction paths without causing harm caused by electrical arcs. To address these issues, the present inventors propose adding sacrificial elec trodem plugs made of refractory alloy powder instead of traditional iron core wires. By doing away with the original design of the immersion type elecerochromatography furnaces, the technical effects include increased accuracy and precision in liquid phase separation, reduced risk of contamination, simplified handling procedures, less thermal stress upon startup, better cooling capabilities, easier replacement of consumables, longer life span, prevention against failure modes like cracks, deterioration under harsh conditions, and avoidance of potential danger zones called hot spikes.
