Abstract

The invention discloses a prefabricated part for a kiln head cover of a cement kiln and a preparation method thereof. The prefabricated part comprises a wear-resistant layer and a heat-insulating layer which are formed by pouring from bottom to top in sequence; A T-shaped groove is arranged between the layers, the depth of the T-shaped groove is 1 / 2 of the thickness of the preform, and the thickness ratio of the wear-resistant layer and the thermal insulation layer is 3:1; preparation method : S1: casting and vibrating the wear-resistant layer; S2: casting and vibrating the heat-insulating layer above the wear-resistant layer; S3: baking, cooling and cooling to obtain a prefabricated part for a kiln head cover of a cement kiln. The prefabricated part of the kiln head cover of the cement kiln prepared by the invention has high strength, good heat insulation, prevention of heat loss and excellent wear resistance.

Description

technical field [0001] The invention relates to the technical field of environmental protection and energy-saving materials, in particular to a prefabricated part for a kiln head cover of a cement kiln and a preparation method thereof. Background technique [0002] The main equipment in the firing workshop of the new dry process cement production line includes rotary kiln, precalciner, cyclone preheater and grate cooler. Reasonable long-term, safe and stable operation. With the development of rotary kilns to large-scale, the inner space of the kiln head cover is getting larger and larger, and the lining of the kiln head cover is often cracked and peeled off due to wear resistance, frequent sudden changes in cold and heat, and thermal shock. The kiln head cover of cement kiln is generally composed of calcium silicate board and refractory castable. Although the technology is more advanced, it is necessary to weld the anchors in advance, and then install the cut calcium silica...
