Transient heat transfer model of kiln wall and kiln crust thickness optimization;

In the process of using sintering technique of rotary kiln to produce alumina,the shape of kiln crust is complex and the temperature measurement is difficulty.

During the process of producing alumina in the rotary kiln with sintering technique,the shape of kiln crust is complex and the temperature measurement is difficult.

The physicochemical properties of matte-kiln-crust, su ch as its chemical component, phase compositions, phase distribution, component s on the micro-area, smelting point, viscosity and so on, were investigated by use of various kinds of experimental ways.

The formation mechanism of the iron-kiln crust in the high temperature zone is investigated.

Study on Protective Effect of Slag-kiln Crust in Volatilizing Kiln of Zinc Leached Residue and Its Application;

We prepare the refractory in burning zone of rotary cement kiln through different pressing and burning schedule and draw the following conclusion through detecting the physicochemical characteristics in the room temperature and high temperature, kiln coating adherence and erosion-resistance to clinker.

This paper analysis the common technical malfunctions problems for the new dry rotary kiln,such as how to stable decomposition of limestone and burning temperature which brought about over burning clinker and under burnt clinker, established one intellectualized control system of the new type try-process burner was put forward.

The main topic of this paper discusses the problems existing in the system of pre-decomposing kiln, and then shows some improving measures of the problems and effect of these measures.
