EAF bottom needs load-bearing, high temperature resistant, heat insulation function to be possessed and have enough mechanical strengths and tightness.Mesh
Before widely used bottom construction (as shown in Figure 1 and Figure 2) be more than locomotive face, to lay steel plate or cast steel plate as base plate 1,
One layer of magnesia brick bed course 3 is built again by laying bricks or stones on base plate 1.The weak point of this structure is as the use time to be increased, due to load-bearing and touch
Hitting effect, the magnesia brick on upper strata can gradually loosen so that it is overall structure performance declines, and not only tightness reduces, insulation effect declines,
Safety is significantly reduced.Additionally use magnesia brick to build bed course 3 by laying bricks or stones and there is also that cost is high, manually build time length by laying bricks or stones and labor intensity is big
Etc. drawback.
Summary of the invention
This utility model provides the bottom construction of a kind of fused magnesite electric melting furnace, and furnace bottom bed course uses castable
The overall structure form of one-time-concreting molding, has that intensity height, good integrity, weight capacity be strong, that high-temperature-resistant thermal-insulation is good is excellent
Point；The most also there is low cost, convenient construction and reduce the features such as labor intensity, good through practical application effect.
In order to achieve the above object, this utility model realizes by the following technical solutions:
The bottom construction of a kind of fused magnesite electric melting furnace, including base plate, furnace bottom bed course and coaming plate；Described base plate and coaming plate
Being made up of steel plate or cast steel, stove filled along the tube structure of base plate outward flange circumferentially disposed formation radial-sealing, cylinder by coaming plate
Foot mat, furnace bottom bed course is to be poured the overall structure formed by castable；Outside coaming plate, symmetry sets several suspension hook.
Described base plate is octagon, and coaming plate is tied along the octagonal cylinder of base plate outward flange circumferentially disposed formation radial-sealing
Structure, fills furnace bottom bed course in octagonal tube structure.
When described base plate is made up of steel plate, thickness is not less than 20mm；When base plate is made up of cast steel, thickness is not less than 60mm.
Described furnace bottom cushion thickness is 200～250mm.
It is welded to connect between described base plate and coaming plate.
Compared with prior art, the beneficial effects of the utility model are:
1) furnace bottom bed course uses the overall structure form of castable one-time-concreting molding, has intensity height, globality
Advantage good, that weight capacity is strong, high-temperature-resistant thermal-insulation is good；The most also there is low cost, convenient construction and reduce labor intensity etc.
Feature, good through practical application effect；
2) base plate is provided with the tube structure that coaming plate is formed, and castable is directly at the mould of tube structure with base plate composition
Molding is poured as furnace bottom bed course in tool；
3) setting suspension hook on coaming plate, facilitate furnace bottom integral hoisting, simplify installation process further, furnace bottom construction is very convenient.
