Embodiment 1

[0023] Example 1, such as figure 1 , 2 Shown, a kind of grate cooler throat refractory construction method is characterized in that: it comprises the following steps to complete; steel structure installation → Anchor installation → Calcium silicate board installation → Treatment of the interface between old and new castables → Formwork and expansion joints → pouring → Formwork removal and maintenance;

[0024] Said steel structure installation:

[0025] The steel structure includes: shaped steel 1, steel plate 2, first anchor 3, double-layer calcium silicate board 4, expansion joint plate 5, brick support plate 6, second anchor 7, and single-layer calcium silicate board 8.

[0026] Lateral Grate Cooler Throat

[0027] The top of the throat of the horizontal grate cooler adopts H250 type steel 1 with a spacing of about 450mm to ensure that the spacing between anchor pieces is 250mm; the lower part of the steel plate 1 is fully welded with 8-12mm thick steel plates 2; S...

Abstract

The invention discloses a construction method for a fireproof material of a throat part of a grate cooler. The construction method is characterized by comprising the following steps of steel structure installing, anchoring part installing, calcium silicate board installing, new and old castable interface processing, formwork and expansion joint reserving, pouring and formwork demounting and maintaining. The construction method has the beneficial effects that the service life of the throat part of the grate cooler is prolonged through the fireproof material of the throat part of the grate cooler and changing of the structure of the throat part of the grate cooler, and the damaging speed is reduced. Meanwhile, the method is simple in technology and small in engineering amount.

Description

technical field [0001] The invention relates to a construction method of a refractory material in the throat of a grate cooler. Background technique [0002] At present, the refractory material in the throat of the grate cooler is affected by the working conditions, and the damage speed is relatively fast. The general service life is about half a year, which brings hidden dangers to the normal operation of the equipment. In order to improve the service life of the refractory material in this part, we are constantly improving the technology At the same time, it is also constantly summarized and improved; the service life has been greatly improved. Contents of the invention [0003] The purpose of the present invention is to provide a construction method for the refractory material in the throat of the grate cooler, so as to solve the problem that the service life of the refractory material in the throat of the grate cooler has been greatly improved. [0004] The technical ...
