Method for flame spraying of gunite on lining of
For example it is best to repair the lining of a converter immediately after a discharge of steel and slag when the lining temperature is 1 200° to 1 400° C. The method according to the invention also can be used for guniting metallurgical units of a cylindrical shape such as converters and steel-teeming ladles.
Slag splashing technique in converter operationIspatGuru
· With this knowledge one can establish a suitable repair strategy for the worn out regions to extend the campaign life of the linings of the converter. Maintenance and repair techniques of refractory lining include coating with slag. This is done through guniting of the refractory material or by the slag splashing on the damaged refractory lining.
Lining (Refractory)an overview ScienceDirect Topics
· The sintering zone (the burning zone) is characterised by high-temperature (1500–1800°C) corrosion and extreme wear on the refractory lining. For this zone magnesia–spinel or magnesia–chrome bricks or less commonly magnesia-enriched dolomite are used. The burning zone of a rotary cement kiln is normally lined with basic bricks.
Repair of converter liningWanhao Refractory
Repair of converter lining. In the process of steelmaking in converter due to the impact of molten iron and scrap on the lining the scouring of the lining in the smelting of molten steel and slag and the chemical erosion of the slag to the lining the converter lining will be damaged to varying degrees during use. The lining is gradually thinned.
