Task of the present utility model provides a kind of part of organizing a performance of constructing that is used for the blast-furnace tuyere zone, and it improves the soundness at this position by shape and the size that changes blast-furnace tuyere zone structural member for building, thereby prolongs the work-ing life of blast furnace integral body.
For finishing above-mentioned task, the utility model according to the characteristics in blast-furnace tuyere zone design one group with other position structural member for building of blast furnace subassembly inequality.This subassembly contains the separate piece (1 of three kinds of shapes at least, 2,3), separate piece 1 and separate piece 2 all are cuboids or are similar to cuboid, and make the cancave cambered surface that is complementary with blast-furnace tuyere equipment peripheral shape on a face of above-mentioned two separate piece, separate piece 3 is to be provided with a tenon in the cuboid end; The above-mentioned volume that is equipped with separate piece is 5～20 times that the used standard type in other position of blast furnace is built the part volume by laying bricks or stones.With the blast-furnace tuyere zone that the subassembly of this kind structure is built by laying bricks or stones, the equipment masonry construction peripheral with it in air port is similar to forms an integral body.So can improve the weight capacity and the corrosion resistance in zone, air port, prolong the work-ing life of blast furnace integral body with firm partial measure.
One end of the cancave cambered surface of above-mentioned separate piece 1 is along the boss that extends radially outwardly out of this cambered surface.
Above-mentioned each separate piece build by laying bricks or stones should make each separate piece in conjunction with after the slit interlaced.
Because the utility model has adopted the difform subassembly of large volume in the blast-furnace tuyere zone, it has broken the tradition that people can only build blast furnace with unified canonical form member by laying bricks or stones, prolonged the work-ing life of blast furnace greatly, but also can improve brickwork speed 50%.As to a 350m
3Blast furnace, the economic benefit that is produced in a year can reach more than 1,000 ten thousand yuan.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the surface structure synoptic diagram of three kinds of separate piece of the utility model;
Accompanying drawing 2 is the vertical cross section figure that build blast-furnace tuyere zone, back by laying bricks or stones;
Accompanying drawing 3 is the vertical views of building blast-furnace tuyere zone, back by laying bricks or stones;
Provide the appearance structure of constructing three main separate piece in the subassembly among Fig. 1, wherein, separate piece 1 is cuboid or is similar to cuboid, is provided with the cancave cambered surface 11 that caves inward on one of cuboid bigger face, and the size of its depression radian should be complementary with the radian of blast-furnace tuyere equipment two covers.And the end at cancave cambered surface 11 extends outward a boss 12, and this boss is used to protect air port two covers, in order to avoid air port two covers are subjected to the corrode of liquid scum in the stove.Separate piece 2 also is a cuboid or is similar to cuboid, is provided with a cancave cambered surface that caves inward 21 on big face of cuboid, and the cylindrical radian of this cancave cambered surface and the big cover of air port equipment is complementary.For general blast furnace, an air port equipment periphery only needs four separate piece 1 and eight separate piece 2 to build by laying bricks or stones.But also can select the number of above-mentioned separate piece according to the size of blast furnace.Separate piece 3 is the members that are used to build by laying bricks or stones middle part, two air ports, also can be referred to as sandwich member.Separate piece 3 is relative flat slightly cuboids, and is provided with a tenon 31 in the cuboid end.The volume of each above-mentioned separate piece is 5～20 times of other position of blast furnace used canonical form structural member for building volume, because the increase of each separate piece volume, the steadiness after blast-furnace tuyere zone masonry construction forms can be increased, and also the slit that forms between the separate piece can be reduced.
