Goal of the article is to study the influence of temperature on the stress state of the housing of a continuous rotary unit, to determine the static and geometric parameters in the lining of the housing under the influence of high temperatures. Significance. The housing of a rotary unit, as a rotating shell, under the influence of loads not only bends and deforms in cross-sections, but also is significantly exposed to temperature effects, since the temperature during material firing reaches 1600…2300 ºС.

It is proposed to execute control of linearity of geometrical axis of rotary kilns’ frame by electronic devices. Use of them enhance operativeness and accuracy of measurement.

Existing optical-mechanical control methods and means of linearity of rotary furnace’ axis are very complicated and do not provide needed accuracy. Proposed new methods of engineer-geodetical control by total stations are not so complicated and provide needed accuracy.

The development of modern geodetic techniques made it possible to monitor large-sized equipment and easy methods with high accuracy. The method of measuring the diameters of the bands by total station directly during control rotary furnaces.

The development of modern technique has led to the improved methods for the determination of geometric parameters of the big-sized rotary kilns. There are methods measuring of the rotary kilns axizes. It is shown, that use total station allow provide effective operation of this equipment.
