Ceramic foam filter UAE is used for smelting and recycling of aluminum scrap

When cutting metal castings, chips account for about 20% of the weight of the casting, up to about 30%. The aluminum shavings in the process of recycling products can reduce production costs and have good economic benefits.

The purpose of waste aluminum pretreatment technology is to realize the mechanization and automation of waste aluminum separation, to maximize the removal of metal impurities and non-metallic impurities, and to effectively separate waste aluminum.
The most ideal method of sorting waste aluminum is to divide the waste aluminum into several categories according to the main alloy composition, such as alloy aluminum, aluminum magnesium alloy, aluminum copper alloy, aluminum zinc alloy, aluminum silicon alloy and so on.
This can reduce the difficulty of removing impurities and adjusting the composition during the smelting process, and can comprehensively utilize the alloy components in the aluminum scrap, especially the aluminum scrap containing high zinc, copper, and magnesium should be stored separately and can be adjusted as a smelting aluminum alloy. Ingredients of raw materials.

The charging principle
1. The order of loading materials should be reasonable. The correct charge depends on the nature and condition of the charge added, and the fastest melting should also be considered
When loading, first install small pieces or thin pieces of scrap, aluminum ingots and large pieces in the middle, and finally the intermediate alloy. The intermediate alloy with easy melting point is installed in the middle and lower layers. The charged materials should be evenly distributed in the molten pool to prevent overweight.
Small pieces or thin plate materials are installed in the lower layer of the molten pool, which can reduce burning loss, and at the same time can protect the furnace body from direct impact and damage of the large pieces of material. Some intermediate alloys have high melting points. For example, AL-NI and AL-MN alloys have a melting point of 750-800 ° C and are installed in the upper layer. Due to the high temperature in the upper part of the furnace, they are easy to melt and have sufficient time to diffuse. Conducive to the composition control of the melt.
The charge is level, and the melting speed is almost the same everywhere. This can prevent the local metal from overheating caused by heavy weight.
The charge should be fed into the furnace once, and two or more additions will increase the non-metallic inclusions and gas content.

Ceramic foam filter UAE is one of the keys to the alloying, purification and refinement of aluminum scrap smelting process. Ceramic foam filter UAE can remove the non-metallic inclusions in the aluminum alloy melt, adopt the flux treatment in the furnace, and the ceramic foam filter technology outside the furnace has already become an important means of aluminum liquid purification.

Ceramic foam filter is specially designed for the production of high-quality foundry products in aluminum casting workshops, reducing waste materials due to impurities, reducing costs due to impurity defects, achieving faster extrusion or hot rolling speed, improving productivity, and easy alloy replacement. Increase casting flexibility without the need to retain metal.
