Metal smelting and pouring system

Abstract

The invention relates to a metal smelting and pouring system which comprises a pouring device and a furnace door device of a smelting furnace. The pouring device comprises an input runner connected tothe smelting furnace and connected with a buffering tank, the furnace door device comprises a furnace door and a furnace door moving device, the furnace door comprises an outer frame side, a mesh-type framework refractory pouring layer arranged in the outer frame side and a full refractory pouring layer, and furnace door moving device comprises a lifting rope connected between the furnace door and a furnace door driver. The metal smelting and pouring system is reasonable in structure and good in pouring liquid delivery quality, and ingot recycling quality of regenerated aluminum is improved.

Description

technical field [0001] The present invention relates to a recycled metal recovery system. In particular, it relates to a metal smelting and pouring system. Background technique [0002] One of the characteristics of recycled metal smelting and recovery including recycled aluminum is that there are a large number of smelting slag, impurities, etc. with a large difference in weight and thickness in the smelting liquid. If the quality of the ingot is serious, the ingot is like bean curd slag when it is reused, and it cannot be used normally. At the same time, the quality of the ingot is also affected by the oxidation problem during the transportation of the smelting liquid, the temperature change of the metal smelting liquid, etc., due to regeneration There is a long gap between the smelting of metal and the process of pouring ingots. To obtain good ingot quality, the transportation of smelting liquid is also a key and important process link. Due to the particularity of the r...

[0002] One of the characteristics of secondary metal smelting and recovery including secondary aluminum is that the smelting liquid contains a large number of sintered ash and impurities with large differences in weight and thickness. When the impurities are not removed in place, it will affect the secondary metal ingot recycling In severe cases, the ingots are like bean curd dregs when they are reused, and cannot be used normally. At the same time, the quality of the ingots is also affected by the oxidation problem during the transportation of the smelting liquid, the temperature change of the metal smelting liquid, etc., due to regeneration There is a long distance between metal smelting and casting ingot process, and the transportation of smelting liquid is also a key and important process link in order to obtain good ingot quality

Due to the particularity of recycling metal smelting liquid, there are certain technical limitations in terms of technology and equipment to purify or filter it. However, the existing metal regeneration smelting ingots include conveying devices such as input channels, etc., due to The structure and the corresponding conduction methods are unreasonable. On the one hand, it is difficult to have effective impurity removal measures. At the same time, due to its long-distance transportation, the casting liquid is cooled and oxidized by the ambient air when it flows through the input channel. A layer of oxide skin formed on the surface is brought into the mold together, and a large number of air bubbles and residues are entrained in the casting liquid. On the one hand, the surface of the ingot is rough, and on the other hand, the residue may form a layer on the surface of the ingot. The residue layer of bean curd slag, and the temperature change of the metal smelting liquid transported over a long distance due to the cooling of the ambient air will affect the smelting recovery efficiency and the quality of the ingot, and secondary heating may be required when the transport distance is long
