Problems solved by technology

However, its disadvantages are as follows: First, the processed quick-change surface is easily stained or damaged in the subsequent production operations such as steel shell installation and glazing.
For example, when installing the steel shell, it often happens that the processed quick-change surface is stained by refractory mud, and the quick-change surface is stained by the glaze when the anti-oxid

Example Embodiment

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings of the specification, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0031] see Figure 1-Figure 6 , Quick-change immersion nozzle steel shell installation device, which is composed of two parts of support frame 1 and positioning frame 2. Positioning frame 2 is assembled in support frame 1, used to fix quick-change immersion nozzle 3, making quick-change immersion type The vertical axis 36 of the steel pouring channel of the nozzle 3 is perpendicular to the bottom plane of the steel shell, so that the horizontal line 40 at the center of the outlet hole 35 of the quick-change immersion nozzle is parallel to the two opposite sides of the steel shell 34, and the positioning frame 2 can be carried by the quick-change immersion The nozzle 3 vertically moves up and down relative to the support frame 1....

Abstract

The invention relates to a quick-changing submerged nozzle and steel shell installation device and method. The installation device is composed of a supporting frame and a positioning frame, wherein the positioning frame is assembled in the supporting frame and is used for fixing a quick-changing submerged nozzle to ensure that the vertical axis of a cast steel passageway of the quick-changing submerged nozzle is vertical to the bottom plane of a steel shell and the central horizontal connection line of a discharge hole of the quick-changing submerged nozzle is in parallel to two opposite sides of the steel shell, and the positioning frame can carry the quick-changing submerged nozzle to move vertically up and down relative to the supporting frame. The installation device has the advantages that the steel shell is installed before milling and grinding of a quick-changing surface, then glazing operation is performed after fire clay is dried, milling and grinding of the quick-changing surface are finally performed with the bottom surface of the steel shell as a datum, and thus the perpendicularity of the processed quick-changing surface and the cast steel passageway of the submerged nozzle is guaranteed; as the surface milling is performed in the final procedure, the processed quick-changing surface can be prevented from contamination and damages of other operation steps.

Description

technical field [0001] The invention relates to a production process equipment of a quick-change submerged nozzle, in particular to a quick-change submerged nozzle steel shell installation device and method for continuous casting. Background technique [0002] Quick-change submerged nozzle is the most widely used protective cast refractory product in the steel continuous casting production process. It is used in conjunction with a specially designed quick-change mechanism to quickly replace the submerged nozzle that has reached the end of its service life on-line to improve production efficiency. During quick change, the new submerged nozzle slides from the spare position in the quick change mechanism to the casting position by hydraulic pressure in the guide groove of the quick change mechanism, and squeezes the submerged nozzle to be replaced away from the casting position. Complete the quick replacement of the submerged nozzle under the circumstances. After the quick cha...
