Abstract

The utility model discloses a hot stuffy slag pool for steel slag, which mainly includes reinforced concrete walls (1) on the four walls of the slag pool, and is characterized in that several T-shaped grooves (2) are arranged on the side walls of the reinforced concrete wall (1) One or more H-shaped steels (3) are inserted in each T-shaped groove (2), and more than two steel billets are inserted between the H-shaped steels (3) in two adjacent T-shaped grooves (2) ( 4). The utility model can divide the original whole billet from top to bottom into multiple pieces for installation without adding fixing devices, thereby reducing the volume of each billet, increasing the number of free ends of the billet and reducing the number of each billet. The deformation of the billet increases the service life of the hot stuffy slag protection and its fixing devices, reduces the production cost and improves the operation rate.

Description

A hot stuffy slag pool for steel slag

technical field

The utility model belongs to the field of metal smelting, in particular to a hot stuffy slag pool for steel slag.

Background technique

At present, the four walls in the hot slag pool of steelmaking slag need to use steel billets as guard plates to protect the pool wall of the hot slag pool. Due to the technical requirements of the hot slag pool, it is necessary to pour hot steel slag at 1100°C into the stuffy slag pool , and then pour water to cool. The protective plate of the hot stuffy slag pool currently used is to install multiple steel billets with the same length and depth as the hot stuffy slag pool around the hot stuffy slag pool and fix them with the wall of the hot stuffy slag pool with long bolts. Large temperature changes in the slag pool (from 1100°C to about 80°C) lead to large deformation of the billet guard plate and deformation of the guard plate fixing bolts, which eventually lead to failure of the fixing device, inward dumping of the guard plate, and production interruption. Due to the large volume and thickness of the billet, it is difficult to restore the original shape, and the maintenance and replacement time is long. Since the fixing bolts of the guard plate penetrate the side wall of the hot stuffy slag pool, it is quite difficult to replace it, and sometimes the ground needs to be destroyed. In addition, because the hot stuffy slag pool is in a high-temperature alkaline steam environment during production, it leads to equipment maintenance and replacement. Frequently. The existing hot stuffy slag pool guard plate and its fixing device have relatively short service life, high production cost, and great impact on production.

Utility model content

The purpose of the utility model is to provide a steel slag hot stuffy slag pool that can be quickly installed or replaced, and can reduce the deformation of the billet and increase the service life.

The purpose of this utility model is a hot stuffy slag pool for steel slag, which mainly includes reinforced concrete walls on the four walls of the slag pool. Insert multiple H-shaped steels one by one or in sections, and insert more than two billets between the H-shaped steels in two adjacent T-shaped slots. A gap of 1 to 10mm is left between the T-shaped groove, the H-shaped steel and the billet.

The replacement and installation of the H-shaped steel and steel billet of the utility model can be installed by a crane in the factory building, which is convenient and fast, can save a lot of installation time, and provides a guarantee for the smooth progress of production. The utility model can divide a whole steel billet from top to bottom into multiple pieces for installation, and does not need to add fixing devices, can reduce the volume of each steel billet, increase the number of free ends of the steel billet, and further reduce the number of each steel billet The amount of deformation increases, the service life of the hot stuffy slag guard and its fixing devices is increased, the production cost is reduced, and the operation rate is improved.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figures 1, 2, and 3, a hot stuffy slag pool for steel slag mainly includes reinforced concrete walls 1 on the four walls of the slag pool. Several T-shaped grooves 2 are arranged on the side walls of the reinforced concrete wall 1, and each T-shaped Insert one or multiple H-shaped steel 3 into the slot 2 (the H-shaped steel can be divided into two or more sections if the slag pool is deep), and insert more than two pieces of H-shaped steel 3 in two adjacent T-shaped slots 2 The billet 4. A gap of 1 to 10 mm is left between the T-shaped groove 2, the H-shaped steel 3 and the billet 4.

The number of T-shaped grooves 2 in the hot stuffy slag pool can be arranged according to the size of the slag pool, and the size of the H-shaped steel 3 is determined according to the thickness of the steel billet 4. The size of the T-shaped groove 2 is determined according to the size of the H-shaped steel 3. According to the size of the T-shaped groove The size of 2 determines the size of the reinforced concrete wall 1. And determine the size of each billet according to the deformation of the billet.

When installing or replacing, only need to insert the H-shaped steel 3 in the T-shaped groove of the side wall with a crane, and then insert the steel billet 4 of the corresponding size between the H-shaped steel 3 in two adjacent T-shaped grooves 2 . Due to the plug-in type between each part, the installation or replacement time can be greatly reduced and the production efficiency can be improved. Since there is a certain gap between the T-shaped groove 2, the H-shaped steel 3 and the steel billet 4, the deformation and destructive force generated by the expansion of the billet can be reduced or even eliminated, and the protection plate and its fixing of the hot stuffy slag pool are improved. The service life of the device greatly reduces production and maintenance costs.
