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] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 to Figure 3 As shown, one aspect of the present invention provides a filter screen support seat, comprising: a filter screen placement port 1 for placing a filter screen; The net placement port 1 is communicated; and the molten iron guide channel 3 is used for connecting 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 base is configured so that the molten iron is filtered through the filter screen placed in the filter screen placement port 1, and then enters the molten iron slow-flow chamber 2, and then enters the outside through the molten iron guide channel 3. cavity. Of course, in addition to molten iron, other metal water can also be used for casting, and the present invention is not limited thereto.

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 particularly, to a filter screen support seat, a pouring system and a pouring method. Background technique [0002] Traditional casting uses cupola furnaces to smelt molten metal, but the process of smelting molten metal will emit a lot of dust and waste gas, causing serious environmental pollution. With the country's emphasis on environmental protection, cupola furnaces are gradually replaced by induction furnaces. The induction furnace melts all the raw materials put into the furnace through electromagnetic induction. All the oxide slag produced during the melting process can only be "scraped off" by manual or mechanical means, and this process cannot completely remove the oxide slag, so it is difficult to obtain pure slag. metallic liquid. On the other hand, for the gravity casting of large castings, due to the large drop of the metal liquid during the pouring process, the flow rate...
