Abstract
The utility model discloses a tunnel-type bright annealing furnace with a detachable furnace top for a stainless steel belt; and the furnace top plate of the traditional tunnel-type furnace body is transformed into the detachable furnace top. The furnace top is formed by an iron plate cover, below which refractory fibers are lined; the furnace body is welded into a rectangular box by the iron plate; two sides and the bottom plate of the furnace body are lined with refractory bricks and the middle part of the furnace body are provided with a furnace pipe; flanges are arranged at the periphery of the lower opening of the furnace top cover and the periphery of the upper opening of the furnace body; and the furnace top cover and the furnace body are fixedly connected by fastening screws through the flanges at the periphery; the planes of the flange at the periphery of the furnace top cover and the flange at the periphery of the furnace body are sealed with high-temperature resistant gaskets. The refractory fibers lined below the iron plate cover are fixed by using hanging bars which are welded below the bottom of the iron plate cover. The tunnel-type bright annealing furnace with the detachable furnace top for the stainless steel belt has the advantages that: when the inside of the furnace part needs to be overhauled or the furnace pipe needs to be replaced, the furnace top cover can be dismounted only by unscrewing the fastening screws of the flange at the periphery of the furnace top cover without breaking and dismounting the furnace top cover; thereby, the maintenance cost of a user is saved, the maintenance time is shortened and the normal production is not influenced.
Description
Technical field
The present invention relates to the metal heat treatmet apparatus field, especially refer to the dismountable tunnel like Stainless Steel Band of a kind of furnace roof bright annealing oven.
Background technology
Metal products often will be through bakingout process in the course of processing.Especially Stainless Steel Products also must keep original luminance brightness.So to stainless annealing treatment equipment is various informative vertical horizontal pallet car type and tunnel like arranged now.And, then be in a kind of tunnel like bright annealing oven, to carry out to the thermal treatment of Stainless Steel Band.Stainless Steel Band is entered from this head of stove, and heating zone, cooling section come out from the other end then in the middle of the process of passing through tunnel.Said tunnel is exactly a burner hearth, and the molybdenum filament of middle mount high power is made the heating original paper, up and down thermal insulation material such as four sides lined with refractory bricks.It not is flue that the stove that has also is provided with the horse that metal sheet is welded into.But the four sides of this tunnel like stove all is the box-type furnace that is welded into steel plate; If in use just in case inner heating original paper damages or furnace deformation needs to change; Trouble has just been come, and must sever steel plate, just can change or maintenance work after removing refractory materials.So the structure of body of heater corrected is very important.
Summary of the invention
The objective of the invention is: existing conventional tunnel formula bright annealing oven case structure is corrected, make it to become the dismountable tunnel type furnace body of furnace roof, convenient to inside maintenance and replacing flue.
The technical scheme of technical solution problem of the present invention is: the dismountable tunnel like Stainless Steel Band of furnace roof bright annealing oven; Form by tunnel type furnace body and furnace top cover; It is characterized in that the stove roof plate of tunnel type furnace body is transformed into dismountable furnace roof; Said furnace roof serves as a contrast refractory fibre down by the iron plate lid to be formed, and said body of heater is welded into rectangular box by iron plate, and flue is established in lined with refractory bricks, centre on two side and the base plate; Bead periphery and body of heater upper edge hole periphery are equipped with flange under the said furnace top cover, and furnace top cover is fixedly connected with fastening screw with the flange of body of heater through periphery.
Seal with high temperature resistant liner between said furnace top cover periphery flange and the body of heater periphery flange plane.
The refractory fibre of said iron plate lid lower liner is fixed with being welded on the beneath muscle that hangs of iron plate lid.
The meliority of the utility model is, when body of heater inside needs overhaul or changes flue, as long as unscrew the fastening screw of furnace top cover periphery flange, unloads furnace top cover and just can carry out, and needn't tear down with going to war.For the user practices thrift maintenance cost and time, can not influence ordinary production.
Description of drawings
Fig. 1 is the utility model side (broken section) synoptic diagram;
Fig. 2 is the utility model front schematic cross-section;
Each division name is claimed and numbered among the figure: 1-furnace top cover, 2-flange, 3-body of heater, 4-fastening screw, 5-refractory fibre, 6-hang muscle, 7-elevated-temperature seal pad, 8-refractory brick, 9-flue.
Embodiment
As depicted in figs. 1 and 2, the dismountable tunnel like Stainless Steel Band of furnace roof bright annealing oven is made up of tunnel type furnace body 3 and furnace top cover 1, is that the stove roof plate with former tunnel type furnace body is transformed into dismountable furnace top cover 1.Furnace top cover 1 serves as a contrast refractory fibre 5 down by the iron plate lid and forms; Body of heater 3 is welded into rectangular box by iron plate; Flue is established in lined with refractory bricks, centre on two side and the base plate; 1 time bead periphery of furnace top cover and body of heater upper edge hole periphery are equipped with flange 2, and both flanges through periphery of furnace top cover 1 and body of heater 3 are fixedly connected with fastening screw 4.Seal with refractory seals pad 7 between furnace top cover 1 periphery flange 2 and body of heater periphery flange 2 planes.Be welded with under the iron plate lid and hang muscle 6, refractory fibre 5 is being fixed under the iron plate through hanging muscle 6.
When body of heater inside needs overhaul or changes flue, as long as unscrew the fastening screw 4 of furnace top cover 1 periphery flange 2, the furnace top cover that unloads 1 is sling with loop wheel machine, just can keep in repair body of heater 3 inside.Maintenance finishes, and hangs reposition to furnace top cover 1 again, before putting into, must earlier elevated-temperature seal pad 7 be set level, and uses fastening screw 4 that furnace top cover 1 and body of heater 3 is fastening then.
Claims (3)
1. the dismountable tunnel like Stainless Steel Band of furnace roof bright annealing oven; Form by tunnel type furnace body (3) and furnace top cover (1); It is characterized in that the top board of tunnel type furnace body (3) is transformed into dismountable furnace roof; Said furnace top cover (1) is made up of iron plate and the refractory fibre (5) that serves as a contrast down, and said body of heater (3) is welded into rectangular box by iron plate, and flue (9) is established in lined with refractory bricks on two side and the base plate (8), centre; Bead periphery and body of heater (3) upper edge hole periphery are equipped with flange (2) under the said furnace top cover (1), and both are fixedly connected furnace top cover (1) and body of heater (3) with fastening screw (4) through peripheral flange (2).
