As method of the invention, comprising the following steps:
Big set, middle set, small set are installed, and the transition plates of annular is placed on the step of middle set left end annular；
Annular accommodating space between the circumferential surface and the outer peripheral surface of middle set left end of the big set tilt stage of cleaning；
It with 5mm graphite packing, 5mm copper wire, stirs, be then filled in accommodating space and consolidate after being mixed with water fire clay；
Again with thering is water fire clay to tamp and keep filler face concordant with middle set end face；
Put annular seal plate in the left end of middle set, by annular seal plate along being continuously welded in transition plates, by ring
The outer of shape sealing plate is continuously welded on the inner peripheral surface of big set tilt stage.
Annular accommodating space, is first to use between the circumferential surface and the outer peripheral surface of middle set left end of the big set tilt stage of cleaning
Wire brush is cleared up, and is then cleared up again with air-blowing.
The configuration of the present invention is simple is easy to make, and blast furnace gas can be effectively blocked and leak from big set with middle set faying face, and have
Effect prevents the outer shifting nose of middle set, has ensured the safety in production of enterprise, has improved the production efficiency of enterprise.
