Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] Since the inclined pouring angle of the holding furnace pouring platform of the holding furnace is related to the pouring water speed, within a certain pouring time, the tilting speed value of the holding furnace hydraulic pouring platform should be different between different inclined water outlet angle intervals. If the tilting speed of the holding furnace is too fast, the poured molten steel will gather at the smaller water outlet of the diversion groove, even when it is detected that the molten steel in the mold mouth reaches the critical point (that is, when the extracted edge arc length value is greater than or equal to the predetermined value ), the holding furn...

Abstract

The present invention relates to the production field of casting technique, in particular to an automatic pouring method and system for a heat preserving furnace pouring platform. By collecting an inclined effluent angle of a heat preserving furnace of the heat preserving furnace pouring platform, a pouring reference datum angle of the heat preserving furnace satisfying the pouring amount is obtained. If the inclined angle of the heat preserving furnace is equal to the pouring reference datum angle, the heat preserving furnace stops inclining. After a predetermined time, a molten steel image from a diversion trench discharge hole to a pouring mold gate is collected, and a molten steel flow velocity value is obtained according to the molten steel image. The extracted molten steel flow velocity value is compared with a corresponding predetermined velocity range. When the molten steel flow velocity value exceeds the corresponding predetermined velocity range, the inclined pouring angle of the heat preserving furnace is adjusted to control the flow velocity of the molten steel within the corresponding predetermined velocity range, so as to solve the problems of the existing technology that the inaccurate control on the pouring angle causes molten steel waste when the heat preserving furnace automatically pours, and the pouring efficiency is low.

Description

technical field [0001] The invention relates to the field of casting technology production, in particular to an automatic pouring method and system for a pouring platform of a holding furnace. Background technique [0002] Because there is still a big gap between my country's steel production technology and developed countries, this makes my country's billet production efficiency only 1 / 3 of that of foreign countries. The low production efficiency and energy shortage seriously restrict the development of my country's steel industry. In recent years, the iron and steel industry has developed many new technologies and processes around improving the efficiency of steel production and reducing energy consumption of steel. Among them, mold casting technology is a major energy-saving and consumption-reducing technology, and its application degree has become a measure of steel An important indicator of the level of production technology. [0003] At present, the field of rapid pro...
