Embodiment Construction

[0016] The present invention proposes a stirring chamber for stirring molten metal and its usage method, which will be described below with reference to the accompanying drawings.

[0017] like Figure 1-Figure 4 The schematic diagram of the structure of the molten metal container and the stirring chamber shown. The structure of the stirring chamber shown in the figure is composed of a melt container 1, a stirring chamber 2, an upper stop 3, an upper retarding rib 4, a lower retarding rib 5, a lower bottom 6, a temperature sensor 7 and a liquid-taking / pouring port 8, the top of the mixing chamber 2 is a narrowed upper stop 3, one end of the upper stop 3 is installed with a temperature sensor 7, and the other end is a liquid intake or pouring port 8; in addition, above and below the stirring chamber 2 The inner wall of the melt container 1 is respectively provided with rib-shaped raised upper retarding ribs 4 and lower retarding ribs 5, and the lower bottom 6 of the melt con...

Abstract

The invention discloses a stirring cavity used for stirring metal melt and a use method thereof, which belong to the field of material processing apparatuses for metallurgy, casting, chemical engineering and the like. The stirring cavity structurally consists of a melt container, a stirring cavity body, an upper stop opening, an upper blocking flange, a lower blocking flange, a lower bottom, a temperature sensor and a liquid taking / pouring port. According to the stirring cavity, the melt liquid level inside the stirring cavity is narrowed, so the stirring effect is effectively stopped from transferring to the liquid level, and the problems of melt oxidation and entrapped air risk are solved. The stirring cavity can be applied to various metal melt stirring and casting occasions; when the stirring cavity is used for batch-type casting such as pressure casting, the stirring cavity is adopted as the internal cavity structure of a pouring ladle; when the stirring cavity is used for continuous casting, the stirring cavity is adopted as the internal cavity structure of a melt hot top and can be directly connected with a continuous casting crystallizer; and full automation is realized in the whole process of melt stirring, chemical refining and casting in a pressure casting site.

Description

technical field [0001] The invention belongs to the field of material processing equipment such as metallurgy, casting, and chemical industry, and particularly relates to a stirring chamber for stirring molten metal and a use method thereof. Background technique [0002] In metallurgy, casting, chemical and other material processing fields, it is often necessary to apply various stirring treatments to metal melts, such as: stirring preparation of semi-solid metal slurry, implementing forced homogenization and stirring treatment of metal melts, etc., to Promote the dissolution of elements and make the temperature and composition field of the melt highly uniform. This overall strong shear and stirring treatment of the metal melt can improve the nucleation and growth environment of crystallization, and finally obtain a uniform and fine casting structure. However, strong agitation also causes some disadvantages, for example: agitation breaks the original calm of the melt surfac...
