Aluminum Refiner usage and introduction

An appropriate amount of refining agent is added to the smelting of aluminum alloys, because it can play the role of degassing and removing impurities, so that the aluminum alloy solution is more pure and improves its mechanical properties. There are many precautions for adding refining agent. The following describes the specific use method.

Introduction to the use of refining agent
Generally, Aluminum Refiner is sprayed. It has more contact area with aluminum liquid. The powdered refining agent is sprayed into the solution through the powder sprayer. Generally, nitrogen and argon are used as the carrier for spraying, and a large number of dispersed bubbles will be formed in the aluminum alloy solution. During the bubble floating process, the aluminum melt will be fully contacted to remove the gas and inclusions in the aluminum liquid in time.
Add refining agent should be added according to the weight of the aluminum liquid, because too much or too little will affect the properties of the aluminum alloy, so it must be calculated before adding. During the operation of the refining agent, the operator should freely control the refining flow through the barometer and powder feeder, so as to control the rolling degree of the aluminum liquid, which can reduce secondary pollution.
The amount of refining agent added is 0.10-0.20%, the customer should choose according to the actual situation during use. After the refining agent is added, it must be fully agitated to give full play to the role of the refining agent. The specific slag and pouring should be determined according to the situation. Generally, the pouring is carried out in advance, but the residue cannot be poured.
The above is the introduction of the use method of refining agent. The refining agent contains a variety of metal elements, which plays an important role in the smelting of aluminum alloys. After addition, it can also change the properties of aluminum alloys and make it more widely used, so refining Agent is essential in aluminum alloy smelting.

What are the common effects of adding Aluminum Refiner
In the process of smelting aluminum, degassing and slag removal are required, so an appropriate amount of refining agent needs to be added. The refining agent is easy to decompose at high temperature, and the generated gas is easy to produce hydrogenation reaction, and the adsorption capacity is relatively strong, and it will also escape from the melt, thereby playing the role of purifying the melt, which needs to be used in the refining stage .
The refining agent can be used in various aluminum alloy melts, especially the pure aluminum needs to be cleaned in time during the smelting process, so as to improve the properties of aluminum. When in use, it needs to be sprinkled on the liquid surface, fully agitated and still, and then slag treatment. Some inert gas can be sprayed into the aluminum solution, which has a better effect.
Adding Molten Aluminum Refining needs to pay attention to the amount of control, as far as possible, the weight is 0.3% of the weight of the aluminum liquid, and it must be added according to the purity of the aluminum liquid. During the addition, the temperature of the aluminum liquid needs to be controlled at about seven hundred baidu, and then the switch of the refining irrigation is turned on to purge nitrogen, so as to avoid re-oxidation and make the melt more pure.
The refining agent plays a role of purification. The refining time increases according to the amount of aluminum, and the size of the bottom switch of the tank must also be mastered to avoid clogging of the tube. After adding the refining agent, the utilization rate of the metal can be improved and the mechanical properties of the metal can be improved. Therefore, an appropriate amount of refining agent should be added according to the situation of the aluminum liquid.
