Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0019] like figure 1 As shown, it is a structural schematic diagram of an embodiment of the electroslag remelting furnace with stable lifting in the present invention. The electroslag remelting furnace with stable lifting in this embodiment includes a crystallizer 1 and a vertical support 2 located on one side of the crystallizer 1. The vertical support 2 is provided with a cross arm 3 slidingly fitted thereon. The end of the cross arm 3 away from the vertical pillar 2 is located above the crystallizer 1 and is provided with a holder 4, on which an electrode 5 protruding into the crystallizer 1 is clamped and fixed. , the holder 4 includes two oppositely arranged clamping pieces ...

Abstract

The invention discloses an electroslag remelting furnace stably rising and falling. The electroslag remelting furnace comprises a crystallizer and a vertical supporting column which is provided with a cross arm slidably matched with the vertical supporting column. A clamping device is arranged on the end, being located above the crystallizer and being away from the vertical supporting column, of the cross arm. An electrode stretching into the crystallizer is fixed to the clamping device in a clamped mode. The clamping device comprises two oppositely arranged clamping pieces. A clamping cavity used for clamping the electrode is formed between the two clamping pieces. Distributor plates connected with a power supply device are arranged on the side wall of one side of the cross arm. Connecting cables are arranged between the distributor plates and the two clamping pieces. A lifting slide sleeve is arranged at the other end of the cross arm. The vertical supporting column is provided with a driving mechanism which comprises a driving motor fixedly mounted at the top end of the vertical supporting column. An output shaft of the driving motor is fixedly connected with a threaded screw rod. A limiting base is arranged at the lower end of the vertical supporting column and sleeves the lower end of the threaded screw rod in a rotary cooperation mode. The lifting slide sleeve is provided with an inner threaded sleeve matched with the threaded screw rod.

Description

technical field [0001] The invention belongs to the technical field of electroslag remelting equipment, and in particular relates to an electroslag remelting furnace. Background technique [0002] Electroslag remelting is a method of smelting using the resistance heat generated when the current passes through the slag as a heat source. Its main purpose is to purify metals and obtain steel ingots with uniform and dense clean structure. Steel remelted by electroslag has high purity, low sulfur content, less non-metallic inclusions, smooth surface of steel ingot, clean, uniform and dense, uniform metallographic structure and chemical composition. [0003] Electroslag remelting furnaces are widely used, mainly in the steel industry, 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-stre...
