Embodiment 1

[0054] Such as figure 1 As shown, the embodiment of the present application provides a method for pouring and installing an integral iron hole mud sleeve, which includes the following steps:

[0055] Step S100: Prepare the mud sleeve castable;

[0056] Step S200: making a clay sleeve mold;

[0057] Step S300: casting and forming the mud jacket with the help of the mud jacket mold;

[0058] Step S400: taking out the mud jacket from the mud jacket mold and drying;

[0059] Step S500: Put the mud sleeve into a plastic bag and seal it;

[0060] Step S600: cleaning up the old material of the mud jacket to form a mud jacket frame;

[0061] Step S700: apply adhesive around the mud sleeve frame;

[0062]Step S800: put the dried mud jacket into the mud jacket frame and glue it with an adhesive;

[0063] Step S900: Proofreading the mud cover.

[0064] It should be noted that step 100 can be performed before step S200, or after step S200 and before step S300, that is to say, as lo...

Abstract

The application provides an integral pouring and installing method for a taphole mud sleeve and a blast furnace taphole structure, which belong to the technical field of blast furnaces. The pouring and installation method of the integral iron mouth mud sleeve includes: making a mud sleeve mold; casting and forming the mud sleeve with the help of the mud sleeve mold; taking out the mud sleeve from the mud sleeve mold and drying; cleaning the old materials of the mud sleeve to form a mud sleeve frame; Smear the adhesive around the frame; put the dried mud set into the frame and bond with the adhesive. By pouring the integral mud jacket off-line, and then bonding the mud jacket to the inner sleeve frame with an adhesive, the quick replacement of the mud jacket can be realized, the blast furnace shutdown time can be reduced, the blast furnace shutdown rate has been greatly reduced, and the blast furnace shutdown rate has been greatly improved. Blast furnace capacity, reducing production costs.

Description

technical field [0001] The present application relates to the technical field of blast furnaces, and in particular, relates to a method for pouring and installing an integral cast iron sheath. Background technique [0002] At present, the tapholes of blast furnaces are all equipped with iron hole mud sleeves. The function of the mud sleeves is to protect the nozzle of the hydraulic gun from being completely sealed with the tap hole channel during the plugging process. The purpose of blocking the iron gate. [0003] The iron sheath is always eroded by high-temperature slag and iron, and the frequency of damage is relatively high. Normally, a newly poured iron sheath has a service life of 3-6 months. When the taphole sheath is severely worn or damaged, it is necessary to shut down the blast furnace for more than 12 hours to cooperate with the repair of the taphole sheath, otherwise the taphole must be stopped. [0004] Under the existing technical conditions, the method of r...
