Problems solved by technology

[0003] Chinese patent CN203972770U discloses a ceramic filter screen support and flow guide component, which can complete the effective support of the filter screen, but the function of the flow guide part is not perfect
This solution mainly has the following disadvantages: 1) The filtered metal liquid needs to be equipped with an additional ceramic tube to introduce the metal liquid into the cavity, which increases the complexity and cost of the operation; 2) The additional ceramic tube is not positioned when it is docked with the support seat, Butt joint misalignment is prone to occur; 3) The ceramic support seat is easy to be too close to the cavity during use, and the gap between the filter support seat and the cavity cannot be sealed, resulting in gap pouring; 4) The height of the filter support seat is relatively large, plus Porcelain tubes butted on the top will easily lead to an increase in the height of the sand box, further increasing the cost

Embodiment Construction

[0026] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 3 As shown, the present invention provides a filter support seat on the one hand, including: a filter screen placement port 1 for placing the filter screen; a molten iron slow flow chamber 2 located inside the filter screen support seat, the molten iron slow flow chamber 2 and the filter The net placement port 1 is in communication; and the molten iron flow channel 3 is used to communicate the molten iron slow flow chamber 2 with the external cavity.

[0028] It should be noted that, in the above-mentioned embodiment, the filter screen support seat is configured such that the molten iron passes through the filter screen placed in the filter screen placement port 1 to filter, then enters the molten iron slow flow chamber 2, and then enters the outside through the molten iron flow channel 3 cavity. Of course, in addit...

Abstract

The invention provides a filter screen supporting seat. The filter screen supporting seat comprises a filter screen placing opening used for placing a filter screen, a molten iron slow-flow cavity located in the filter screen supporting seat and a molten iron flow guiding channel used for communicating the molten iron slow-flow cavity and an external cavity, and the molten iron slow-flow cavity communicates with the filter screen placing opening. The invention further provides a pouring system combining the filter screen supporting seat with the molten iron flow guiding channel and a pouring method thereof.

Description

technical field [0001] The invention relates to the technical field of casting, and more specifically relates to a filter screen support seat, a pouring system and a pouring method. Background technique [0002] Traditional casting mostly uses cupolas to smelt molten metal, but a large amount of dust and exhaust gas will be emitted during the process of smelting molten metal, causing serious environmental pollution. With the country's emphasis on environmental protection, cupolas are gradually replaced by induction furnaces. The induction furnace melts all the raw materials put into the furnace through electromagnetic induction. All the oxidized slag produced during the melting process can only be "removed" by manual or mechanical means, and this process cannot completely remove the oxidized slag, making it difficult to obtain pure metal liquid. On the other hand, for the gravity casting of large castings, due to the large drop of the metal liquid during the pouring proces...
