Description

Continuous casting filter device for liquid copper and its alloys

technical field

The utility model relates to an upward-leading continuous casting filter device for liquid copper and its alloys, which is mainly used for filtering solid impurity components such as molten slag and carbon slag in the upward-leading continuous casting device for liquid copper and its alloys.

Background technique

In the production process of cable products such as copper and its alloy catenary wires, contact wires, and suspension wires, in order to ensure the stability of the alloy composition of the products and the excellence of the material structure, the upward continuous casting method is used to cast them processing. Since charcoal is used for oxygen barrier treatment during the smelting process of upward continuous casting, it is easy to cause inclusions such as charcoal to enter the crystallizer. There are defects such as inclusions in the rod. Therefore, in order to prevent solid impurities such as slag and carbon slag from entering the upward continuous casting rod, it is necessary to use a filter device to filter the liquid copper and its alloys to avoid the above-mentioned defects of the upward continuous casting copper rod.

At present, the filtration methods for metal alloy solutions are mostly found in casting processes such as casting and sand casting, and the filter materials are mostly ceramics and alloys, but the filtration methods for continuous casting are rarely mentioned. Due to the high viscosity and high temperature of liquid copper and its alloys, and the poor adhesion of ceramic or alloy filter materials to solid impurities, the filtering effect on liquid copper and its alloys is not ideal.

Utility model content

The technical problem to be solved by the utility model is to provide a continuous casting filter device for liquid copper and its alloys, which can effectively filter solid impurities such as molten slag and carbon slag in the continuous casting copper rods for the above-mentioned prior art. Guarantee the quality of continuous cast copper rods.

The technical solution adopted by the utility model to solve the above problems is: a continuous casting filter device for liquid copper and its alloys, which includes a graphite cooling tube, a graphite tube sleeve and a graphite filter screen, and the graphite tube sleeve is set in a graphite cooling At the rear end of the tube, the graphite cooling tube and the graphite tube sleeve are connected by bayonet joints. A plurality of holes are evenly opened on the outer peripheral wall of the graphite tube sleeve, and a graphite filter is arranged inside the graphite tube sleeve.

The graphite filter adopts a multi-layer mesh structure, and its surface is honeycomb.

A certain gap is reserved between the graphite filter screen and the bottom of the graphite tube sleeve.

Compared with the prior art, the utility model has the advantages of:

The utility model is a continuous casting filter device for liquid copper and its alloys, which can fully filter solid impurities such as molten slag and carbon slag entering the crystallizer together with the copper liquid through a specially designed graphite filter screen; The graphite filter is a specially treated multi-layer mesh structure, the surface of the material is honeycomb, which has little influence on the flow velocity of the liquid copper alloy, and has excellent adsorption effect on the solid impurity components, which ensures the efficient filtration of the graphite filter As a result, it overcomes the characteristics that the viscous liquid copper and its alloys are not easy to filter, and has many advantages such as good filtering effect and less influence on the flow velocity of liquid copper and its alloys.

detailed description

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 ~ Fig. 3, a kind of liquid copper and its alloy in the present embodiment lead continuous casting filtering device, it comprises graphite cooling tube 1 and graphite tube cover 2, and described graphite tube cover 2 is set in graphite cooling tube At the rear end of the tube 1, the graphite cooling tube 1 and the graphite tube sleeve 2 are connected through bayonet joints. A plurality of holes 4 are evenly opened on the outer peripheral wall of the graphite tube sleeve 2, and the inside of the graphite tube sleeve 2 is provided with Graphite filter 3;

The graphite filter screen 3 adopts a multi-layer mesh structure, and its surface is honeycomb;

A certain gap is reserved between the graphite filter screen 3 and the bottom of the graphite tube sleeve 2 .

It works as follows:

Liquid copper and its alloys enter the interior of the graphite tube sleeve and the graphite cooling tube through the specially designed holes of the upward lead graphite tube sleeve, and the flow mode and direction are shown by the arrows in Figure 1. When liquid copper and its alloys flow through the graphite filter, the graphite filter is a specially designed multi-layer mesh structure, and the surface of the material is honeycomb, which has a strong adsorption effect on non-melted solid impurities, and can Solid impurity components such as slag and carbon slag contained in the continuous casting of liquid copper and its alloys have a high-efficiency filtering effect, and have little influence on the flow velocity of liquid copper and its alloys. In addition, there is a certain gap between the graphite filter and the bottom of the graphite tube sleeve, which allows the solid impurities adhering to the graphite filter to accumulate to a certain extent and then automatically settle to the bottom of the graphite tube sleeve to prevent it from blocking the graphite filter and prolong graphite filtration. The service life of the net. After that, the filtered liquid copper and its alloys enter the graphite cooling tube for rapid cooling and crystallization.

In addition to the above-mentioned embodiments, the utility model also includes other implementation modes, and any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the claims of the utility model.
