Embodiment

[0040] The bottom of the 300-ton carbon-free steel ladle in H Steel Plant uses carbon-free prefabricated brick masonry. The leakage of molten steel into the permanent layer of the bottom of the ladle often occurs after the bottom of the ladle is used, posing safety hazards. After changing the bottom of the bag to the integral pouring mode, the leakage of molten steel has been eliminated, but it is difficult to repair the bottom of the bag and it is difficult to unpack it. When the package is unpacked, the castable material at the bottom of the package falls off in one piece, resulting in waste of refractory materials.

[0041] A carbon-free steel ladle composite cladding bottom construction technology, after being applied to the 300-ton carbon-free steel ladle of H Steelmaking Plant, the leakage of molten steel to the permanent layer of the ladle bottom has never occurred. When the ladle is used for 25 furnaces, the prefabricated bricks in the impact area of ​​the molten steel...

Abstract

The invention provides a carbon-free steel ladle composite ladle bottom constructing technology. The technology is applied to guarantee that the ladle bottom repairing difficulty and the repairing cost are reduced while a ladle bottom is safely used. The carbon-free steel ladle composite ladle bottom constructing technology comprises the following steps that a ladle bottom is cleaned, pouring of perpetual lining casting materials is carried out, maintaining is carried out, pouring of ladle bottom working layer casting materials is carried out, maintaining is carried out, ladle bottom working bricks are constructed, and baking is carried out; and the technology is used for constructing the ladle bottom, the first-layer perpetual lining casting materials can achieve the aims of guaranteeingthe ladle bottom safety and the thermal insulation and heat preservation effect, the second-layer ladle bottom working layer casting materials guarantee the using safety of the repaired ladle bottom,and the third-layer carbon-free prefabricated bricks can be locally replaced and mended by replacing damaged parts. The steel ladle bottom using safety, the ladle bottom repairing difficulty and ladlebottom repairing cost have contradiction all the times, the three-layer refractory material structures of the composite ladle bottom well solve the problems.

Description

technical field [0001] The invention relates to the repair and use of the bottom of a refined carbon-free ladle in the iron and steel metallurgy industry, and is a construction process for a composite bottom of a carbon-free ladle. Background technique [0002] Iron and steel metallurgy technology is developing rapidly, the smelting process is diverse and complex, and high temperature and high vacuum smelting are gradually increasing. This is more and more higher to the use requirement of carrying molten steel container. The refining ladle is the container with the harshest conditions in the molten steel refining process. The application of special refractory materials in the ladle is relatively large, and the configuration of refractory materials is diverse. While various refractory materials perform different smelting functions, the matching of the life of each refractory material becomes the key to the overall life of the ladle. [0003] Due to the different service li...
