Problems solved by technology

[0003] At present, the ignition equipment used in domestic vacuum refining furnaces has long relied on imports, and the imported ignition devices are split into two - three sections, assembled on site (see figure 1 ), the conduit 2 and the high-voltage ignition cable 3 are segmented, and are butted and connected through the helical structure 21 of the conduit and the helical structure 31 of the high-voltage ignition cable respectively. Splicing together, what's more, due to shaking and other reasons during the operation of the equipment, the joints are easy to loosen

Embodiment Construction

[0013] from figure 2 , image 3 It can be seen from the figure that an ignition device for a vacuum refining furnace is composed of an ignition head 1, a conduit 2, a high-voltage ignition cable 3, an ignition transformer 4, and a lifting cylinder 5. The conduit 2 is an integral seamless steel pipe, and its straightness is guaranteed after measures such as straightening and centerless grinding. The external thread of one end of the ignition head 1 is spirally connected with the internal thread of one end of the conduit 2, and one side of the external thread of the ignition head 1 extending into the conduit 2 is reinforced with a set screw 6, and the high-voltage ignition cable 3 is connected with the ignition The end of head 1 with external thread is fixedly connected by nut 7; after conduit 2 passes through lifting cylinder 5, its other end is screwed on ignition transformer 4, and then reinforced with set screw 8; one end of high-voltage ignition cable 3 is connected to le...

Abstract

The invention discloses an ignition device for vacuum refining furnace with smart structure and stable quality. The ignition device is formed by the combination of an ignition head, a duct, a high-voltage ignition cable, an ignition transformer, and a lifting cylinder; the ignition head is firstly connected with the high-voltage ignition cable and then linked with the duct; the duct is an integrated seamless steel pipe; the ignition transformer is firstly connected with the high-voltage ignition cable and then linked with the duct. The device has the advantages that due to the integrated design of the ignition device, the clever structure is characterized by not needing centration, and successfully solves the problems of poor contact due to unideal centration when the imported similar equipment is installed on the steel-making site and the falling of an ignition pipe due to the jitter of equipment in the running process, thereby avoiding a series of losses; simultaneously, the installation process is simplified and product qualification rate and quality are greatly improved; the ignition device is widely applied to Tangshan Iron and Steel Company, Handan Steel, Baoshan Iron & Steel Co., Ltd., and Xinyu Steel.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to an ignition device for a vacuum refining furnace which is used on a steelmaking furnace in vacuum refining of molten steel (RH method) and a preheating gun which is ignited and ignited Structural improvements. Background technique [0002] Vacuum refining of molten steel (RH method) is a new type of smelting technology in the metallurgical industry. The top gun and preheating gun equipment used in it are the most important mechanical equipment, and these two equipment must be ignited before work. gas. [0003] At present, the ignition equipment used in domestic vacuum refining furnaces has long relied on imports, and the imported ignition devices are split into two - three sections, assembled on site (see figure 1 ), the conduit 2 and the high-voltage ignition cable 3 are segmented, and are butted and connected through the helical structure 21 of the conduit and...
