The underflow type passage mechanism comprises a communication pipeline (3) used for communicating a smelting furnace (1) and a heat insulation furnace (2), wherein alloy solution (13) is set in a structure and can flow to the heat insulation furnace (2) from the smelting furnace (1) along the communication pipeline (3), an outer ring of the communication pipeline (3) is respectively provided with a heating device (4) and a cooling device (5), and the underflow type passage mechanism also comprises a control component (6) used for controlling the opening and the closing of the heating device (4) and the cooling device (5). The mechanism and the method provided by the invention have the advantages that the structure is simple, the dismounting and the assembly are convenient, the long-period contact of the alloy solution and the air can be avoided, the zinc oxidation is reduced, and the alloy solution quality is improved.

Description

technical field [0001] The invention belongs to the technical field of alloy solution converters, and more specifically relates to a submerged channel mechanism for alloy solution converters. The invention also relates to a method for controlling alloy solution flow using the submerged channel mechanism for alloy solution converters. Background technique [0002] In the prior art, the alloy solution in the melting furnace needs to be flowed into the holding furnace by using the height difference between the high and low furnaces, and there is an exposed launder in the middle. When the launder structure transports the alloy solution, the alloy solution is in contact with the air, and the metal zinc in the alloy solution with a low melting point undergoes an oxidation reaction with the external oxygen, resulting in large zinc loss, high heat loss, and white zinc oxide powder. , is brought into the air by the airflow, causing great environmental pollution and causing great harm...

AI Technical Summary

Problems solved by technology

When the launder structure transports the alloy solution, the alloy solution is in contact with the air, and the metal zinc in the alloy solution with a low melting point undergoes an oxidation reaction with the external oxygen, resulting in large zinc loss, high heat loss, and white zinc oxide powder. , is brought into the air by the airflow, causing great environmental pollution and causing great harm to the health of production employees

At the same time, when the alloy solution flows into the holding furnace through the tank, air and sundries will be brought in, resulting in pores and inclusions in the casting billet, which will affect the product quality

The holding furnace is always in the open state. Although there will be a layer of slag on it, it is often exposed to the air and oxygen, and the zinc loss will also increase, and the heat loss will also increase.
