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 & SteelCo., Ltd., and Xinyu Steel.
Description
Technical field
The present invention relates to technical field of metallurgical equipment, relate in particular to the top rifle that uses on the converter in the molten steel vacuum refining (RH method), preheating rifle and the architecture advances of a kind of ignition device for vacuum refining furnace of igniting for its igniting.
Background technology
Molten steel vacuum refining (RH method) is a kind of novel smelting technique of metallurgy industry, and use therein top rifle, preheating rifle equipment are wherein vital plant equipment, the combustion gas wherein and these two kinds of equipment must ignite before work.
The equipment that ignites that uses on the present domestic vacuum refining furnace depends on import for a long time; The ignition device of import is split as two---and three sections,, assembly unit (see figure 1) at the scene; Conduit 2 and high-voltage ignition cable 3 segmentations; The helical structure 31 of helical structure 21 through conduit and high-voltage ignition cable docks and is connected simultaneously respectively, and during the assembly unit butt joint, often bad or other reason can't be stitched together owing to high-voltage ignition cable 3 centerings; What is more in equipment running process owing to reasons such as shakes, and unclamp easily the joint.
Therefore, structure how to improve above-mentioned ignition device for vacuum refining furnace has just become research topic of the present invention.
Summary of the invention
The objective of the invention is: the shortcoming situation to the import ignition device has proposed ingenious, the stay-in-grade ignition device for vacuum refining furnace of a kind of structure.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of ignition device for vacuum refining furnace is combined by ignition head, conduit, high-voltage ignition cable, ignition transformer, lift cylinder; The one termination external screw thread of ignition head and the internal thread of conduit one termination carry out spiral and connect, and stretch into the externally threaded side of ignition head of conduit simultaneously and reinforce with holding screw, and high-voltage ignition cable has externally threaded this termination to be fixedly connected through nut 7 with ignition head; Conduit is through behind the lift cylinder, and its other end spiral is reinforced with holding screw on ignition transformer again; One termination of high-voltage ignition cable is connected with ignition head, and its another termination is connected with ignition transformer.
Advantage of the present invention is: owing to be designed to all-in-one-piece ignition device; Be that conduit is an integral seamless steel pipe; High-voltage ignition cable also is a monoblock type; This structure characteristics cleverly is without centering, and to produce centering when installing undesirable and the loose contact that occurs and equipment are shaken in running and the appearance point fire tube comes off in that steel-making is on-the-spot successfully to have solved the import same category of device, avoided a series of loss; Simplify mounting process simultaneously, greatly improve product percent of pass and quality.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done description further.
Fig. 1 is the partial structurtes explosion views of existing product segmentation butt joint;
Fig. 2 is the product structure figure of one embodiment of the invention;
Fig. 3 is the A face structure enlarged drawing of Fig. 2.
Among the figure: 1, ignition head; 2, conduit; 21, the helical structure of conduit; 3, high-voltage ignition cable; 31, the helical structure of high-voltage ignition cable; 4, ignition transformer; 5, lift cylinder; 6, holding screw; 7, nut; 8, holding screw.
The specific embodiment
Can find out that from Fig. 2, Fig. 3 a kind of ignition device for vacuum refining furnace is combined by ignition head 1, conduit 2, high-voltage ignition cable 3, ignition transformer 4, lift cylinder 5.Conduit 2 is an integral seamless steel pipe, and through guaranteeing its linearity after the measures such as alignment, centreless grinding processing.The one termination external screw thread of ignition head 1 and the internal thread of conduit 2 one terminations carry out spiral and connect; Stretch into ignition head 1 an externally threaded side of conduit 2 simultaneously and reinforce with holding screw 6, high-voltage ignition cable 3 has externally threaded this termination to be fixedly connected through nut 7 with ignition head 1; Conduit 2 is through behind the lift cylinder 5, and its other end spiral is reinforced with holding screw 8 on ignition transformer 4 again; One termination of high-voltage ignition cable 3 is connected with ignition head 1, and its another termination is connected with ignition transformer 4.
This courage is widely used in Tangshan Iron and Steel Co, Handan steel mill, Baoshan Iron & Steel Co., Ltd, Xinyu steel mill.
