Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
The refractory protection 100 for metallurgical furnace of the utility model embodiment is described referring to Fig. 1.
As shown in Figure 1, comprise heat-insulation layer 10 according to the refractory protection 100 for metallurgical furnace of the utility model embodiment, be located at heat-insulation layer 10 above and by laying fireproof bricks permanent layer 20, be located at permanent layer 20 above and by laying fireproof bricks working lining 30 and be located at working lining 30 and the first impermeable layer 40 formed by ramming mass above.
The refractory protection 100 for metallurgical furnace according to the utility model embodiment is stacked gradually defined an entirety by heat-insulation layer 10, permanent layer 20, working lining 30; permanent layer 20 and working lining 30 adopt refractory brick to pile up and form to make protective layer have good fire resistance; and the first impermeable layer 40 of being made up of ramming mass is set above working lining 30 to cover the brickwork joint between the refractory brick forming working lining 30, make refractory protection 100 have good anti-permeability.
In a preferred embodiment, refractory protection also comprises the second impermeable layer 50 being located at and being formed between heat-insulation layer 10 and permanent layer 20 and by ramming mass.Like this, the second impermeable layer 50 is arranged between heat-insulation layer 10 and permanent layer 20 to strengthen the anti-permeability of refractory protection 100 further.One of ordinary skill in the art will appreciate that, the constituent of the first impermeable layer 40 and the respective concrete thickness of the second impermeable layer 50 and ramming mass can be arranged as required.
Advantageously, the side docking of the adjacent refractory brick 31 of working lining 30 or partial transposition, side is inclined-plane.Particularly, in the concrete example shown in Fig. 2, two adjacent refractory brick docking of composition working lining 30, namely the side of two refractory brick 31 overlaps completely.In the concrete example shown in Fig. 3, two adjacent refractory brick 31 partial transpositions of composition working lining 30, namely the side of two refractory brick 31 only partially overlaps.
Further, the refractory brick 31 of working lining 30 is truncated rectangular pyramids shape or wedge shape.Particularly, in the concrete example shown in Fig. 4, the refractory brick 31 of working lining 30 is truncated rectangular pyramids shape, and the extended line of four inclines of this truncated rectangular pyramids meets at a bit.In the concrete example shown in Fig. 5, the refractory brick 31 of working lining 31 is wedge shape, and the extended line of the incline of this wedge shape intersects on straight line.Thus, lock mutually between refractory brick adjacent in working lining 30, refractory protection 100 inside is connected tight, reliable.
With reference to Fig. 1, between working lining 30 and the first impermeable layer 40, be also provided with the barrier bed 60 of the brickwork joint between the refractory brick covering working lining 30.Thus, barrier bed 60 covers the brickwork joint of working lining 30 with the brickwork joint preventing foreign matter from entering working lining 30.
Wherein, the refractory brick of working lining 30 and/or permanent layer 20 is the one in magnesia brick, magnesite-chrome brick, magnesia-alumina brick, magnesia carbon brick, alumina chrome brick, carbon brick, silicon carbide brick.Like this, the high temperature resistance of refractory protection, erosion resistibility is enhanced.
Preferably, heat-insulation layer 10 is built by laying bricks or stones by clay brick or high-alumina brick and is formed.Thus, heat-insulation layer 10 has the advantages such as heat insulation, sound insulation, the moisture absorption.
When the refractory protection of the utility model embodiment is applied on metallurgical furnace, the furnace bottom of metallurgical furnace adopts refractory protection, and heat-insulation layer 10 forms the outside of furnace bottom, and the first impermeable layer 40 forms the inner side of furnace bottom.In metallurgical furnace blow-on temperature-rise period, the first impermeable layer 40 can prevent the motlten metal in metallurgical furnace from entering working lining 30; The bottom temperature of metallurgical furnace raises and after maintaining a period of time, the refractory brick of working lining 30 fully expands and brickwork joint between adjacent refractory brick fully makes up, even if the first impermeable layer 40 is worn, the brickwork joint of working lining 30 closes, and the motlten metal in metallurgical furnace still can be stoped to infiltrate working lining 30.
