Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown in FIG. 2 , the non-ferrous metal smelting and heat preservation composite furnace of this embodiment includes a smelting furnace 1 and a heat preservation furnace 3 , and a continuous casting crystallizer 4 is provided at the exit 32 of the heat preservation furnace 3 . A channel 31 is provided between the smelting furnace 1 and the holding furnace 3, and the channel 31 is a conduit 31a made of a material with good high temperature resistance. A control valve 2 is provided at the channel 31, and the valve 2 is an adjustable valve with adjustable flow rate. It includes a valve body 24 and a valve stem 22. The valve body 24 is placed horizontally on the bottom of the melting furnace 1. The upper side of the middle part of the body 24 is provided with an insertion cavity 25 into which the valve stem 22 can exten...

Abstract

It relates to a non-ferrous metal smelting and heat preserving composite furnace comprises smelting and heat preserving furnaces and through ways between them, control valve at the through way, featuring in one end of the said through way connecting with the bottom of the smelting furnace, the other end connecting with the heat preserving furnace bottom, and the outlet of the heat preserving furnace at the bottom of the heat preserving furnace. Compared with existing techniques, it can effectively avoid the consumption of evaporable and oxidizable metals, reducing material cost, improving production environment, and prevents unsatisfactory effect on the quality due to the drawing of air of the smelting metal. It does not interfere with the heat preserving furnace casting, keeping consistent alloy composition control with that of the detachable furnace, realizing feeding through furnaces, with the highest working temperature rising up to 1500 DEG C, with extensive application.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal casting furnaces, in particular to a smelting and heat preservation composite furnace applied to the regeneration of yellow miscellaneous copper. Background technique [0002] At present, the traditional process of using scrap copper to produce brass rods is to melt the raw materials in the melting furnace first, and then pour the molten copper into the holding furnace for continuous casting after the composition of the copper liquid is qualified. Volatilizes to form white zinc oxide mist, which not only causes metal loss, but also pollutes the production environment. From the analysis of the mechanism of zinc mist generation, it can be known that a layer of zinc oxide film will be formed on the surface of the copper liquid when it is left standing, which hinders the further evaporation of zinc, but the copper liquid is disturbed when the furnace is poured, which destroys the zinc oxide ...
