Titanium iron smelting rotary kiln

The process of directly reducing ilmenite in a rotary kiln refers to feeding qualified raw materials such as ilmenite to a rotary kiln. In the rotary kiln, the generated high-temperature flue gas forms a countercurrent motion with the material, and the charge is heated to 900-1050 ° C. Up to 1150 ° C, the ilmenite is reduced to a high grade titanium-rich material. We added the temperature measurement and automatic adjustment control system of the rotary kiln on the original basis to ensure the quality of the calcined product. In addition, a special cylinder insulation device is used to ensure efficient use of heat.

product description

Technical performance and characteristics

Kiln head injection furnace coal gasification

Coal gasification is carried out using a gas generator to produce a producer gas rich in CO and H2, which is injected into the kiln to supply heat to the reduction reaction and provide a portion of the reducing agent.

Efficient use of heat, automated control

The rotary kiln lining is made of composite kiln lining with refractory castable and thermal insulation castable. The rotary kiln establishes an automatic control system, which can conveniently and quickly control the temperature of each point in the kiln to ensure that the temperature fluctuation is small and strive to reach a constant temperature.

working principle

The rotary kiln direct reduction method is the main method for coal-based direct reduction industrial production. The process of directly reducing ilmenite in coal-based rotary kiln refers to sending qualified ilmenite raw materials and partially reduced coal to the workshop daily silo, according to After a certain proportion of ingredients, the belt conveyor is sent to the kiln end feeding end, and is fed into the kiln through the feeding tube. The rotary kiln has an inclination of 2.5-3°, and the loaded charge is slowly moved toward the discharge end by the rotary motion and the inclination of the rotary kiln. The burning coal and part of the reduced coal are injected from the discharge end of the kiln head and burned with a certain amount of primary air to generate high temperature flue gas. The flue gas and the charge are countercurrently moved, and the charge is heated at 900-1050℃, not exceeding 1150℃, and the ilmenite is reduced to a high grade titanium rich material.
