Product advantages: Aluminum and aluminum alloy additives adopt a metal powder addition mechanism, achieving stable element yield and an economical production method, avoiding the burning loss of aluminum and alloy elements caused by high melting temperature; At the same time, the molten salt contained is beneficial for purifying the aluminum liquid.

Instructions for use: Aluminum and aluminum alloys can be directly added to the furnace or holding furnace before refining. In order to achieve the desired yield of alloy elements, the following aspects need to be coordinated.

1. Operating temperature:

Aluminum and aluminum alloy additives are sensitive to temperature, so the temperature of the aluminum liquid needs to be controlled at 750 ± 5 ℃ when adding additives; Otherwise, it will prolong the stay time.

2. Slag removal:

Additives should be added after removing the surface scum to prevent them from being wrapped or floating by the scum.

3. Let it stand still

In order to effectively control the uniformity and stability of the alloy composition, the additive needs to be left to stand for 20 minutes after addition, so that the metal elements can fully react with the aluminum liquid; After standing still, stir to evenly distribute the alloy elements.

4. Joining method and process

Directly adding the additive into the molten pool will automatically sink, and with the gasification reaction of the molten salt, the block agent will float up and down in the aluminum liquid; At this point, a small flame is generated on the surface of the aluminum liquid, and the metal powder particles in the block agent disperse in the aluminum liquid and form aluminum compounds. Until the reaction is complete; The concentration of alloy elements around the bulk agent in the aluminum liquid is very high, and a certain diffusion time or artificial agitation is required to facilitate diffusion.

Usage:

The furnace material is melted and stirred, and samples are taken for analysis; Calculate the amount of additive added based on the analysis results. The formula for calculating the amount of addition is as follows:

Addition amount (kg)=(target value - content of the element before addition) * melt amount/(actual yield 90% * content of the element in the additive 75%)

When the temperature of the aluminum liquid reaches 750 ℃, peel off the floating slag on the surface of the aluminum liquid; Evenly add the additive to the melt and let it stand for 20-30 minutes, then stir for 5 minutes; Let it stand for another 5-10 minutes for sampling and analysis.

Packaging and Storage: 500g/piece, 2kg/bag, 20kg/box, stored in a dry place to avoid moisture.

Shelf life: 6 months

Advantages: 1. Larger and lower cost. 2、 Due to the absence of hydrogenation as the raw material, there will be no increase in gas content in the aluminum melt.

Features: The block weighs 250 grams, contains 20% titanium (50 grams), and the rest is a component of aluminum alloy that can be refined and refined. It can cover the melt to isolate air. This product does not reduce the strontium deterioration effect and does not pollute the aluminum liquid.

Usage: After aluminum melting and slag removal, add 20 # titanium additive into the aluminum liquid at 750 ± 10 ℃, let it stand for about 15 minutes, stir evenly, and take samples for analysis.

Packaging: 250g/piece, 20kg/box

Storage: Keep in a ventilated and dry place, with a shelf life of 12 months.
