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 casing 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 invention provides an integral taphole clay jacket pouring installation method and a blast furnace taphole structure, and belongs to the technical field of blast furnaces. The integral taphole clay jacket pouring installation method comprises the steps that a clay jacket mold is manufactured; clay jacket pouring forming is carried out by means of the clay jacket mold; a clay jacket is taken out of the clay jacket mold and dried; clay jacket old material is cleared to form a clay jacket frame; the periphery of the clay jacket frame is coated with an adhesive; and the dried clay jacket is putted into the clay jacket frame to be bonded with the adhesive. According to the method, the integral clay jacket is subjected to offline pouring, and then the clay jacket is bonded in the clay jacketframe through the adhesive so that the operation of quickly replacing the clay jacket can be realized, the blowing-down time of a blast furnace is shortened, the blowing-down rate of the blast furnace is greatly reduced, the productivity of the blast furnace is improved, and the production cost is reduced.

Description

technical field [0001] The present application relates to the technical field of blast furnaces, in particular, to a pouring and installation method for an integral iron hole mud sleeve and a blast furnace iron hole structure. 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 tec...
