    The quality of ladle masonry is related to the service life of nozzle base bricks, breathable bricks, etc., and may also affect the quality of finished steel products. Before masonry, the inner lining material of the ladle needs to be removed. Before unpacking, a certain amount of preparation is required. First, carefully check the thickness of the ladle wall, the bottom of the ladle, the nozzle seat brick, and the air-permeable brick to see if there are large brick gaps. Before entering the ladle, it is necessary to observe whether there is any hanging or loose steel slag on the upper side of the ladle, and make corresponding treatments to avoid the steel slag falling during the operation and causing injury.

    After the unpacking is completed, the overall ventilating bricks, nozzle block bricks, etc. are masonry.

    Masonry of the overall breathable brick: clean the parts of the breathable brick reserved for the permanent layer of the bag bottom; use a crane to align the steel pipe of the breathable brick at the reserved hole at the bottom of the ladle, put it firmly, and sit upright; around the breathable brick and the bottom of the bag The gap between the bricks is filled with castable.

    Masonry of runner block bricks: check the condition of runner block bricks to ensure that there is no cracking, deformation, etc. that affect the use. Generally speaking, the installation accuracy requires that the height of the female socket end face of the block brick and the reference plate of the fixed frame of the mechanism should be less than 125mm, and Measured from any position, the size fluctuation is within 1mm; when installing, put the nozzle block into the positioning ring, rotate the block properly, make the cement and the block have good contact, and sit on the block. At this time, the thickness is required to be ¡Ü1mm ; The gap between the perimeter of the seat brick and the bottom brick of the permanent layer shall be filled with the seat brick repairing material.

    The masonry perfection of the overall breathable bricks and nozzle block bricks occupies a large proportion in the process of ladle masonry, and it is also indispensable for molten steel refining. As a professional refractory manufacturer, firstfurnace@gmil.com has produced breathable bricks, nozzle block bricks, electric furnace covers, etc. for 18 years. It has excellent characteristics such as long life, thermal shock resistance, erosion resistance, and erosion resistance. It has a patented formula and unique design. trustworthy!
