Example Embodiment

[0020] Below in conjunction with the accompanying drawings, the specific embodiments of the present invention are described in one step:

[0021] See figure 1 , figure 2 , is the structural schematic diagram of the embodiment of the flow field intensity indicator of the present invention, including a hanger 1, a horizontal foot 2, a hook 3 and a flow measuring plate 4. The bottom of the hanger 1 is symmetrically provided with a horizontal foot 2, and the hanger 1 A hook 3 and a dial 5 are arranged on the upper, and the flow measuring plate 4 is hung on the hook 3. The flow measuring plate 4 is an integrated structure composed of a pointer 6, a hanging ring 7, a connecting rod 8 and a float 9. A leveling screw 10 is provided at each end of the leveling foot 2 . The hanger 1 is provided with a horizontal horizontal bubble 11 and a vertical horizontal bubble 12 respectively. Before the test, the leveling screw 10 needs to be adjusted so that both the horizontal horizontal bubb...

Abstract

The invention relates to the field of plate blank continuous casting and particularly relates to a method for measurement of flow-field direction and intensity in a crystallizer and a flow-field intensity indicator. The method is characterized in that the flow-field intensity indicator is used to monitor the flow-field intensity and direction in the crystallizer in a casting process and quantitative analysis on possibility of cutting slag of steel slag interfaces in the crystallizer is performed and used as the basis of adjustment of related parameters of the crystallizer. The flow-field intensity indicator is characterized by including a hanger, horizontal footstands, a hook and a flow measurement board. The flow measurement board is an integral structure which is formed through combination of a pointer, a hanging ring, a connecting rod and a floater. Compared with the prior art, the beneficial effects of the flow-field intensity indicator are that an operator is capable of detecting different conditions: different steel types, different pulling rates, different immersed water port insert depths and argon blowing flow and the like so that change rules of the flow field in the crystallizer under different conditions are obtained and thus flowing method of steel water in the crystallizer can be adjusted, controlled and optimized so as to improve external and internal qualities of casting blanks.

Description

technical field [0001] The invention relates to the field of slab continuous casting in iron and steel smelting technology, in particular to a method for measuring the direction and strength of a flow field in a mold and a flow field strength indicator. Background technique [0002] In the process of continuous casting, after the molten steel flow field in the mold flows out from the spit hole of the immersion nozzle, it impacts the copper plate on the narrow side of the mold, and then is divided into upward flow and downward flow, and the quality of the casting billet is good. It is closely related to how the flow stream in the device operates. At present, there are equipment such as mold expert system for monitoring the flow field in the mold, but it only monitors the changes of temperature and friction in the mold, and there is no effective monitoring equipment and means for the change of flow field form and flow field intensity. [0003] Affected by the casting speed, t...
