Microstructure Analysis of Used Silica Brick in Coke Oven of Meisteel

Microstructure analysis shows quartz remains more or less in used silica brick for coking chamber of coke oven, and quartz gradually becomes metastable cristohalite and then translates into tridymite in used brick for high temperature combustion chamber.Phase change of silica brick only limits to transformation of quartz and metaslable cristohalite.When finished,structure of silica brick tends to stable.Carbon sedimentates and graphitizes helping to protect the silica brick and improve heat conductivity of silica brick for coking chamber.

Study and Application of Sealing Material for Coke Oven Chamber

1IntroductionSome coke ovens have been in operation for over20years in Baosteel,cracks and leaks are found in thesilica brick walls and roofs of coke oven.The existenceof cracks causes the emission of smoke from ovens,which may probably affect the service life of oven.Thewall surface is often destroyed by the extension ofcracks,resulting in eventual shutdown of the oven.Inorder to obtain stable coke oven operation over a longterm,many kinds of repair techniques,such as hot re-pairing,gunning,…

Research and Application of Wear Resistant Refractories for Cooling Zone of Large Scale Coke Dry Quenching Ovens

In order to prolong the service life of the cooling zone of large scale coke dry quenching ovens,six kinds possible refractories for the cooling zone of large scale coke dry quenching ovens: SiC containing brick A,SiC containing brick B,mullite-andalusite brick,spinel containing brick,zirconia containing brick,corundum-mullite brick and grade B mullite brick,were analyzed in properties. It is found that the cooling zone lining adopting SiC containing bricks or mullite-andalusite bricks has much longer service life. Based on this,a new type of wear resistant brick was developed. The brick has a compressive strength of 135 MPa,a wear loss of 2. 10cm~3(only a quarter of that of the grade B mullite brick),and a higher bulk density than the grade B mullite brick. The application of the brick in a 140t·h~(-1)coke dry quenching oven showed that it performed better than the grade B mullite brick. The cooling zone adopting the new bricks has a lower coke discharging temperature,which is beneficial to the enhancement of heat recovery efficiency and steam power generation.
