Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention, but the examples cited are not intended to limit the present invention.

[0025] Such as figure 1 Shown is a schematic structural diagram of an embodiment of an electroslag remelting furnace accurately positioned in the present invention. The electroslag remelting furnace accurately positioned in this embodiment includes a mold 1 and a vertical pillar 2 located on one side of the mold 1. The vertical pillar 2 is provided with a cross arm 3 that is slidably fitted with the cross arm 3, and the cross arm 3 is away from the vertical support. One end of 2 is located above the mold 1 and is provided with a holder 4, and an electrode 5 extending into the mold 1 is clamped and fixed on the holder 4. The holder 4 includes two clamping pieces 6 disposed oppositely, and ...

Abstract

The invention discloses an electroslag remelting furnace with the accurate positioning function. The electroslag remelting furnace with the accurate positioning function comprises a crystallizer and a vertical supporting column located on one side of the crystallizer; the vertical supporting column is provided with a transverse arm in sliding fit with the vertical supporting column; the end, away from the vertical supporting column, of the transverse arm is located above the crystallizer and provided with a holder; an electrode extending into the crystallizer is clamped and fixed to the holder; the electroslag remelting furnace with the accurate positioning function further comprises a transverse arm lifting mechanism used for controlling lifting of the transverse arm, a stand column rotation mechanism used for controlling the vertical supporting column to rotate, and an electrode centering mechanism used for centering and positioning of the crystallizer and the electrode; the electrode centering mechanism comprises a supporting seat fixedly arranged below the crystallizer and a position adjusting mechanism used for adjusting the position of the supporting seat; the crystallizer is fixedly installed on the supporting seat; universal idler wheels are arranged below the supporting seat; and photoelectric sensors used for detecting the position of the electrode are annularly and evenly arranged on the top face of the crystallizer.

Description

Technical field [0001] The invention belongs to the technical field of electroslag remelting equipment, and specifically 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 the metal and obtain a clean, uniform and dense steel ingot. The steel remelted by electroslag has high purity, low sulfur content, few non-metallic inclusions, smooth, clean, uniform and dense ingot surface, and uniform metallographic structure and chemical composition. [0003] Electroslag remelting furnaces are widely used, mainly in the steel industry and metallurgical industry. The use of 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...
