Description
Technical field
The utility model belongs to converter fire resistive material product field, more particularly to a kind of converter bottom and molten bath transitional brick.
Background technology
Steel-making is very big with the consumption of refractory brick, and directly affects life-span and the smelting cost of converter.Converter
Working lining is directly contacted with high-temperature molten steel, slag, by the chemical erosion of high-temperature slag, is washed away by molten steel, slag and furnace gas, also
By adding mechanical impacts during steel scrap etc. to act on, working environment is very severe.In converting process, due to the condition of work at each position
Difference, deteriorate situation and the amount of deteriorating of liner is also different.For this situation, the difference of the damaged condition of backup lining brick is built by laying bricks or stones
The refractory brick of unlike material or identical material different stage, here it is so-called integrated block heater.It is easily damaged or is difficult the portion of repairing
Position, builds high-grade magnesia carbon brick by laying bricks or stones;Damage relatively light and easily repair position, middle-grade or low-grade magnesia carbon brick can be built by laying bricks or stones.
Flat brick masonry is returned in traditional converter bottom and the use of building by laying bricks or stones at molten bath position, returns the position that flat brick is contacted with bottom brick
It is the inclined-plane for returning flat brick.The corrode of furnace bottom and the molten iron of the existing molten condition of molten bath position working environment, has and adds steel scrap again
Gouging abrasion, and gas can cause to wash away during blowing.Bottom brick can reduce height because corroding during converter use, expose
Bottom brick and the contact site for returning flat brick.That returns flat brick and bottom brick builds that direction is different easily to produce gap by laying bricks or stones, can increase furnace bottom
The danger of position drill steel.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provide a kind of simple in construction, easy to maintenance, anti-to invade
Erosion ability is strong, can increase the thickness of converter molten pool position brick, it is to avoid the converter bottom in gap and molten bath transitional brick occurs in brick body.
In order to solve the above technical problems, what the utility model was realized in.
Converter bottom and molten bath transitional brick, its transitional brick body are in hexahedron structure；The top surface of the transitional brick body with
Bottom surface is parallel；The top surface and bottom surface are isosceles trapezoid；The area of the top surface is less than base area；The base of the top surface
And waist base corresponding with bottom surface and waist it is parallel successively.
As a kind of preferred scheme, two base length of top surface described in the utility model are：48mm≤A≤99.2mm；
76.5mm≤B≤100.7mm；Two base length of the bottom surface are：52.5mm≤C≤129.2mm；83.5mm≤D≤
130.6mm。
Further, transitional brick body described in the utility model is a height of：850mm≤L≤1000mm.
The utility model adds molten bath position again in the case where not influenceing the liquid steel level height of smelting process requirement
The thickness of brick, while avoiding causes the danger of drill steel using returning flat brick and gap easily occur.Add furnace bottom and molten bath transition
The corrosion resistance at position, makes furnace bottom and the erosion rate at molten bath position reach synchronization, is provided for the later maintenance of converter lining
It is convenient.

Embodiment
As shown in Figures 1 to 3, converter bottom and molten bath transitional brick, its transitional brick body 1 is in hexahedron structure；The transition
The top surface 201 of brick body 1 is parallel with bottom surface 202；The top surface 201 and bottom surface 202 are isosceles trapezoid；The top surface 201
Area is less than the area of bottom surface 202；The base of the top surface 201 and waist are parallel successively with the corresponding base in bottom surface 202 and waist.
Two base length of top surface 201 described in the utility model are：48mm≤A≤99.2mm；76.5mm≤B≤
100.7mm；Two base length of the bottom surface 202 are：52.5mm≤C≤129.2mm；83.5mm≤D≤130.6mm.This reality
It is a height of with the new transitional brick body 1：850mm≤L≤1000mm.
The utility model can be always built to molten bath in operation is actually built by laying bricks or stones from furnace bottom, make the transition of bottom brick and molten bath brick
The magnesia carbon brick in region can be perpendicular to converter shell direction.In the case where not influenceing the molten steel page height of smelting process requirement
The thickness of molten bath position brick is added again, while avoiding causes the danger of drill steel using returning flat brick and gap easily occur.Increase
Furnace bottom and the corrosion resistance of molten bath intermediate location, make furnace bottom and the erosion rate at molten bath position reach synchronization, are Converter
The later maintenance of lining provides facility.
It is to be understood that specifically described above with respect to of the present utility model, be merely to illustrate the utility model and not
The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, still can be with
The utility model is modified or equivalent substitution, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
