Abstract

The utility model discloses a whole fibre furnace door which is used for a rolled steel heating furnace. An n-shaped frame (1) is manufactured by using a steel plate welding or casting method, the inner side of a top beam of the frame (1) is weld with a plurality of perforating ribs (2) or is fixed with a plurality of perforating ribs (2) by screw bolts, and a refractory fibre blanket (4) penetrates through the perforating ribs (2) in a sheety mode and is tightly arranged in an inner cavity of the frame (1). After the total thickness of the refractory fibre blanket (4) achieves the requirement which is needed, a press plate (3) is arranged on the other end of the perforating rib (2), the press plate (3) is tightly screwed and presses the refractory fibre blanket (4), and the refractory fibre blanket is matched with a lifting mechanism of the normal furnace door. The whole fiber furnace door has the advantages of light weight, long service life, convenient maintenance, convenient replacement and favorable heat insulation effect, and can be widely used for various heating furnaces or forging furnaces.

Description

Heating furnace is with full fiber fire door

Technical field the utility model relates to a kind of full fiber fire door of using on heater for rolling steel or the forge furnace of being applied to, and belongs to the F23C5/02 class.

The fire door of background technology heater for rolling steel is a consumable accessory, particularly heating furnace end charging and discharging fire door and with conventional with brick or water the fire door of material feeding construction, often have shortcomings such as big, the anti-contingency ability of weight, life-span weak point, the easy oxidation of steel member, deformed damaged, heat-insulating property difference, these shortcomings are used at the middle fire door of CSP (abbreviating CSP as) heating furnace and are showed more obviously.In the heating furnace operation process, because fire door needs frequent lifting, the fire door of other versions is very short service life, might cause bigger miscellaneous equipment damage or product rejection in case control is broken down.Before the utility model, no matter the well-known specialized company of home or overseas does not all also solve the good scheme of this difficult problem, the way that the selection of many producers is given it up, not only heat loss is big, goes back near the steel construction piece of easy burn-out fire door, and contaminated environment.

Summary of the invention task to be solved in the utility model provides a kind of full fiber fire door of new structure, and this full fiber fire door has that making is easy to maintenance easily, in light weight, the advantage of long service life, good heat-insulation effect.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: make " ㄇ " type framework with the sheet metal welding or with casting method, wear muscle at the inboard welding of the back timber of this framework or the bolt N root steel that is connected, being fixed on steel with the several layers of refractory fiber blanket certain thickness, that size is suitable wears on the muscle, after the number of plies of wearing the refractory fiber blanket folded piece on the muscle or gross thickness reach necessary requirement, wear supporting pressing plate or press strip on the muscle at every, remove this boatswain chair that on framework, also is connected.

Adopt heating furnace that as above technical scheme makes with full fiber fire door compared with prior art, its advantage is: 1. weight has only about 1/10 of former fire door; 2. can improve 3～5 times service life; 3. using water wisely; 4. make with easy to maintenance; 5. good heat-insulation effect.

Description of drawings

Fig. 1 is the Facad structure schematic diagram of heating furnace described in the utility model with full fiber fire door, also is specification digest accompanying drawing of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic.

The specific embodiment is described in further detail the specific embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in drawings, 1 is framework, and 2 for wearing muscle, and 3 is pressing plate, and 4 is refractory fiber blanket, and 5 is boatswain chair.Boatswain chair 5 is connected in the outside of framework 1 back timber, welding of framework 1 available metal steel board or casting are made into " ㄇ " shape structure, on the inboard of framework 1 back timber equidistant or not disposed at equal distance N root (N＞1) wear muscle 2, wear one of muscle 2 with can adopt welding or bolt fixed mode being connected of framework 1 back timber, refractory fiber blanket 4 passes in the inner chamber that muscle 2 in layer is assemblied in framework 1, when the gross thickness of the refractory fiber blanket 4 in framework 1 inner chamber reaches necessary requirement, adjacent refractory fiber blanket 4 is installed pressing plate (or press strip) 3 in the other end of wearing muscle 2, and each layer refractory fiber blanket 4 compressed.Pressing plate (or press strip) 3 can adopt special-shaped fastener to fix welding or tacks by the hole of wearing on the muscle 2 with wearing being connected of muscle 2.

During enforcement, be applied to the use scene with the heating furnace that assembles with full fiber fire door, in the circular hole of boatswain chair 5, again steel wire rope linked to each other with the lowering or hoisting gear of conventional fire door with the tight bolt of steel wire rope, promote or the decline fire door according to the produced on-site needs, realize purpose described in the utility model.

Claims

1, a kind of heating furnace is with full fiber fire door, by framework (1), wear muscle (2), pressing plate (3), refractory fiber blanket (4), boatswain chair (5) and form, it is characterized in that: boatswain chair (5) is connected in the outside of framework (1) back timber, framework (1) is " ㄇ " shape structure, disposed inboard at framework (1) back timber has N root (N＞1) to wear muscle (2), refractory fiber blanket (4) passes muscle (2) and is assemblied in the inner chamber of framework (1), at the adjacent refractory fiber blanket in other end (4) of wearing muscle (2) pressing plate (3) is installed.
