Infrared positioning device for mounting iron shell on submerged nozzle and operation method thereof

Abstract

The invention discloses an infrared positioning device for mounting an iron shell on a submerged nozzle and an operation method thereof. The infrared positioning device comprises a base and an infrared gradienter, wherein a cylindrical positioning block is arranged on the upper surface of the base; the positioning block is connected with an axial casting hole; the infrared gradienter is arranged in front of the base; leveling devices used for adjusting a submerged nozzle are arranged between the base and a submerged nozzle base; when the infrared positioning device is used, the submerged nozzle is arranged on the upper surface of the base; the cylindrical positioning block is inserted into the axial casting hole; the infrared gradienter is started; the leveling devices are arranged betweenthe upper surface of the base and the lower surface of the submerged nozzle base; a dual-cross positioning line of the infrared gradienter is overlapped with the center of the base and a radial casting nozzle; the infrared positioning device is capable of ensuring that the submerged nozzle is vertically arranged and simultaneously ensuring that the side hole is not deviated; then the submerged nozzle is coated with fire clay and is covered with the iron shell; and the upper surface of the iron shell is adjusted to be horizontal state. The infrared positioning device is capable of improving the mounting accuracy of the iron shell and the submerged nozzle and ensuring that axes of the iron shell and the submerged nozzle can be overlapped.

Description

technical field [0001] The invention relates to the field of processing and assembly of a submerged water inlet, in particular to an infrared positioning device for installing an iron shell of a submerged water inlet. Background technique [0002] The submerged water inlet is widely used in the casting field. Its main function is to prevent the secondary oxidation of the tundish injection flow and the splashing of molten steel during the casting process, to prevent the mold slag from being involved in the molten steel; to improve the flow state of the injection flow in the mold and heat distribution. And thereby promote the uniform growth of the billet shell in the crystallizer, which is beneficial to the removal of gas and inclusions in the steel. Since the submerged nozzle has remarkable effects on improving the quality of the slab, improving the working conditions, stabilizing the continuous casting operation, and preventing the surface defects of the slab, it is adopted...

Problems solved by technology

[0004] In order to solve the deficiencies in the prior art, the present invention provides an infrared ray positioning device for the installation of the iron shell of the submerged water inlet, which solves the problem that the positioning clamp cannot ensure the distance between the submerged water inlet and the iron shell after being fixed during the clamping process. The axis coincides, resulting in a decline in product quality and technical problems such as low yield
