Ferro Titanium 70

Ferro Titanium 70, an intermediate alloy of titanium and iron, is used as a purifying agent for steel.

The international market has a large demand for high-titanium ferro-titanium with high titanium content, but my country's current ferroalloy factories generally only produce ordinary medium and low-titanium ferro-titanium. For high titanium iron with (Ti) 65%-75% and (Al) ≤4%, few manufacturers officially produce it.

Abnormal phenomena in ferrotitanium smelting:

1) When the wet charge is mixed with the charge, boiling occurs, the furnace gas escapes unevenly, and a large amount of charge is sprayed out; magnesia contains moisture and is also sprayed when making a sand nest. 

2) The charge is mixed unevenly and the smelting proceeds unevenly.

3) The unit heat distribution is low, the reaction is slow, and the smelting time is long. The reason is that the reducing agent is insufficient, the calorific value is low, or the preheating temperature of the charge is low, resulting in a cold stroke of smelting. There is more slag stuck to the bottom of the iron ingot, there are more iron particles in the slag, or the iron ingot is poorly fused and is loose or contains slag.

4) The unit heat distribution is high or the preheating temperature is high, the reaction is violent, the slag is stirred, causing slag spraying, the iron ingot is hard and difficult to break, the iron ingot contains high aluminum content, and the output is reduced.

Factors affecting titanium recovery rate in high ferrotitanium smelting:

1) As the unit heat distribution increases, the titanium recovery rate increases. But when the heat distribution reaches 3250kj/kg, the titanium recovery rate decreases.

2) When the unit heat distribution is constant, as the amount of lime increases, the recovery rate of titanium increases. However, if too much lime is added, the melting point of the slag decreases, the reaction temperature decreases, and the recovery rate of titanium decreases.

3) When the upper part is ignited, the titanium recovery rate can reach more than 73%.

4) The finer the particle size of the aluminum particles, the higher the recovery rate of titanium. In addition to reducing the recovery rate of aluminum particles with large particle sizes, the aluminum content of the alloy also increases.
