Embodiment Construction

[0013] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Depend on Figure 1-Figure 7 Given, the present invention is made up of a plate-shaped grate body 1, a T-shaped positioning sleeve 2 and a checker brick transition block 3, and the grate body 1 is provided with circular through holes 4 evenly arranged at intervals of regular triangles. , the hole walls 5 between the holes all become the load-bearing structure of the grate, and the positioning sleeve 2 is a T-shaped cylindrical body composed of a large ring sleeved on one end of a small cylinder, and the small cylinders are equidistant The intervals are placed in the circular through holes 4 evenly arranged on the grate body 1, the lower end face 6 of the large ring is placed on the hole wall 5 of the grate body, and the positioning on the grate body 1 is placed at intervals. The sleeve 2 forms regularly arranged position...

Abstract

The invention relates to a hot-blast furnace combined grate suitable for stacking checker bricks with different structures, and can effectively solve the problem that the checker bricks are broken due to slippage between the checker bricks and the grate. A grate body is provided with round through holes; each positioning sleeve is a T-shaped cylinders formed by sleeving a big ring at one end of a small cylinder; small cylinders are arranged in the round through holes at equal intervals; the lower end faces of big rings are arranged on the hole walls of the grate body; positioning sleeves arranged on the grate body at intervals form positioning lug bosses; the positioning lug bosses are matched with grooves on checker brick transition blocks; and the checker brick transition blocks are arranged on the grate body and closely combined with the checker bricks. By the hot-blast furnace combined grate, the accuracy of stacking the checker bricks is improved, the through hole rate of the checker bricks is improved, the checker bricks are prevented from being damaged, and the effects of improving a flow field structure and enhancing heat transfer are achieved.

Description

technical field [0001] The invention relates to a combined hot blast stove grate suitable for stacking checker bricks of different structures used in a hot blast stove regenerator of a blast furnace. Background technique [0002] The grate for the hot blast stove is a cast iron structure used to support the regenerator, and usually adopts a whole structure or a structure divided into several large blocks, on which checker bricks are placed directly. It is very easy to cause the small holes of the checker bricks to be difficult to align with the through holes of the large fire grates, resulting in a decrease in the through-hole ratio of the checker bricks. In addition, the thermal expansion coefficient of the grate is quite different from that of the checker brick, which will cause slippage between the checker brick and the grate during operation. This sliding movement cannot be realized due to the load bearing on the checker brick. This will easily cause damage to the check...
