Abstract

The invention discloses a construction method for using a fireproof material in a rotary cement kiln. The construction method is characterized by comprising the following steps of new cylinder cleaning in a construction position; local wire arranging; laying of silicon-mullite series of bricks; laying pressure controlling; rotary kiln reexamining; checking and accepting. The construction method disclosed by the invention has the beneficial effects that the construction safety is ensured through the control on a key link, the laying quality is ensured, and a quality accident is prevented from happening; the construction specification of the fireproof material of the rotary cement kiln is supplemented; an effective laying standard is provided for allocating silicon-mullite series and high-aluminum series to various kiln types; the problems in a traditional laying method that since lot drawing and grape hanging phenomena are generated, the running period is seriously affected, a quality accident is caused, and the external image of an enterprise is seriously affected are solved.

Description

Technical field [0001] The invention relates to the field of cement rotary kiln building, in particular to a construction method using refractory materials in the cement rotary kiln. Background technique [0002] At present, this new technique involves the construction of refractory materials in cement rotary kilns, especially when the construction quality of silicon-mo series and high-aluminum refractory bricks cannot be guaranteed. According to the new technique, the construction quality can be effectively guaranteed. It is a practical type in the general rules of kiln construction. New Technology. The traditional method is based on the old masonry method. There is no condition to rely on effective tools and standards, and the construction quality cannot be guaranteed. Silimo series bricks are alternative products developed and put into the market in recent years. Its characteristics are low thermal conductivity and high strength. However, its surface is flat and tradition...
