Flux For Rotary Furnace SALT BATH FOR ROTARY FURNACE

General Description

The most commonly used furnace in the secondary aluminium industry is the rotary furnace where aluminium scrap is melted under a layer of salt which consists of a mixture of chlorides and cryolites. There are various possible combinations of this salt flux. However after several trials and customers feedbacks, Flux 475 has proved to be the best combination for Aluminium melting in Rotary furnace.

Advantages :

• Flux 475 enhances the heat transfer to the metal
• It prevents the oxidation of the metal
• The salt takes up contaminants, such as oxides, carbides and others contained in the scrap or produced by reactions during the melting process
• Homogenous mixture for the alloy is achieved
• Helps in cleaning, covering as well as drossing of molten aluminium

Application Instructions for use :

The amount of salt used for the melting process depends on the scrap characteristics and varies in a range of 5-8% of the aluminium scrap charge.

First, the salt is melted down in the rotary furnace. Next the scrap is charged into the salt bath. After the metal is molten it is tapped and the salt slag is cast into steel moulds where it cools down. The advantage of the rotary furnace is that even highly contaminated scrap can be handled.

Features:

• Covering fluxes prevent oxidation losses of aluminium during melting. Thus improving the yield of molten metal from the charge.
• Drossing-off fluxes absorb oxides and non-metallic inclusions. It reduces the incidence of inclusions in the castings and also reduces the loss of metal through the dross.
• Modifying fluxes improve the mechanical properties of aluminium – silicon alloys by refining eutectic microstructure.
• Recovering fluxes help extract maximum aluminium from hot dross.
• Reclaimed fluxes minimise the melting losses associated with the melting of chips, turnings and borings.
• Furnace cleaning fluxes retain the melting capacity and efficiency of furnace while improving the life of the refractory lining

General Description:

ZINCREX range of fluxes are in powder form and are used for protecting and cleansing zinc and its alloys during melting and for high recovery of zinc from drosses.

Purpose:

Normally zinc is prone to oxidation during melting and the dross formed contains lot of metallics in it.

ZINCREX range of products help in reducing the oxidation during melting as well as recovering metallics from the dross.

Benefits:

ZINCREX range of products:

1. Curtail formation of zinc oxide and hence metal losses 
2. Ensure scimming with low metal content 
3. Clean the metal thoroughly and absorb suspended bodies and dirt 
4. Enalble recovery of clean metal from low grade skimming and drosses

Instructions for use:

ZINCREX Standard

Add sufficient ZINCREX(about 0.25% by weight) during early stages of melting to form cover. When the change is compeletely molten, add a further 0.25% of ZINCREX and plunge and rabble well into the melt, preferably with a perforated plunger. After all reactions have ceased, allow the melt to settle for a few minutes before skimming clean and pouring.
ZINCREX-85

Allow the dross to cool and blacken overall so that all flame has died out and there are no visible incandescent hot-spots, which could cause excessive fumes.Do not let the temperature rise above 400⁰C during treatment.Rabble the black dross and add ZINCREX-85 until a powdered residue is obtained.On rabbling further, the application rate (usually from 0.25 to 0.5% depends upon the quantity of dross treated. Avoid excessive additions and add a little at a time.Skim the powdery residue with a perforated skimmer. Once a good separation is obtained, do not restir.For maximum metal recovery, place the skimmer in a preheadted in a conical shaped dross cart, where with stirring more metal is released through the bottom.

 

Standard Packing: 20kg fibreboard drum

Precaution:

ZINCREX compounds are hydrophobic and the containers should be kept securely closed when the products are not in use.
