Description

TECHNICAL FIELD

[0001] The utility model relates to a novel electroslag remelting furnace technical field, specifically, a novel electroslag remelting furnace. BACKGROUND

[0002] The novel electroslag remelting furnace is a device for remelting metal by using the heat energy generated by electric current through high-resistance slag.

[0003] The electroslag remelting process is that the lower end of the electrode is immersed in molten slag. A large amount of heat is generated when the alternating current passes through the high-resistance slag pool, which melts the end of the electrode immersed in the molten slag. The metal droplets generated by melting pass through the slag pool and drop into the metal pool, and then are cooled and condensed into ingots by the water-cooled crystallizer. In this process, the metal droplets are in full contact with the high-temperature high-alkalinity slag, producing strong metallurgical chemical reactions, which refines the metal. The steel subjected to electroslag remelting has high purity, low sulfur content, few non-metallic inclusions, smooth and clean ingot surface, uniform and dense, uniform microstructure and chemical composition.

[0004] The novel electroslag remelting furnace has wide application, and is mainly applied in the steel industry, the metallurgical industry, etc. Different slag materials can be used to refine various alloy structural steels, heat-resistant steels, bearing steels, forging die steels, high-temperature alloys, precision alloys, corrosion-resistant alloys, high-strength bronze, and other non-ferrous metal alloys such as aluminum, copper, iron, and silver; different shapes of crystallizers can be used to directly produce high-quality cast steel parts such as large-diameter steel ingots, thick slabs, hollow tube blanks, large diesel engine crankshafts, rolls, large gears, high-pressure containers, and gun barrels.

[0005] In the electroslag remelting process, the molten metal may not completely solidify into steel ingots after passing through the crystallizer. At this time, the metal liquid and sparks in the furnace body are easy to splash onto the surrounding equipment, causing damage to the surrounding equipment. UTILITY MODEL CONTENTS
