Embodiment Construction

[0005] Such as figure 1 As shown, the direct pouring filling layer is between the mold and the remaining lining. The pouring material is poured from direction A, and the tip of the pneumatic pick vibrates at the load-bearing point on the inner wall of the mold. When the ladle lining has reached its service life, there is no need to remove the working layer, only the residual steel on the bottom and wall of the ladle needs to be removed. Fill the bottom of the bag first, and then sit on the wall-wrapped mold after the health preservation is completed. The cavity between the mold 1 and the original working layer 2 is the layer to be filled, and the pouring material of the same material with specially made smaller particles is injected into the filling layer. Weld multiple load-bearing points 3 on the inner wall of the mold, and vibrate the inner wall of the mold with a pick to make the pouring material continue to flow down until it reaches the density (the density is slightly ...

Abstract

The invention relates to a working-layer-demounting-free direct pouring method of a pouring-formed ladle lining. The method includes: without demounting a working layer, after a wall-wrapping mould is seated, forming a cavity, namely a filling layer, between the mould and the original working layer, injecting special pouring materials small in particle and identical in material into the filling layer, and vibrating the inner wall of the mould with an air pick to enable the pouring materials to flow downwards continuously until the density (the density is slightly smaller than that of a conventional vibrating method by a vibrating rod) is reached. The method is simple in process, high in efficiency and low in power consumption, and cost can be saved by more than 40%. Besides, the method can be widely used as a method for pouring ladle linings of steel plants.

Description

Technical field: [0001] The invention relates to a production method of a ladle lining in a steelmaking plant, in particular to a method for direct pouring of a pouring-formed ladle lining without dismantling a working layer. Background technique: [0002] When the pouring formed ladle lining reaches the end of its service life, the working layer needs to be removed for pouring operations. The construction period is long, the labor intensity is high, and the consumption of refractory materials is high, resulting in a lot of waste. What was invented: [0003] The invention overcomes the deficiencies of the prior art and provides a direct pouring method without demolition of the working layer. The direct pouring method of pouring formed steel ladle lining without dismantling the working layer is: without dismantling the working layer, after sitting on the wall-wrapped mold, the cavity formed between the mold and the original working layer is filled with special small par...
