Abstract
A conveyor belt (1) for a strand sintering furnace. The conveyor belt (1) is formed into an endless loop from a number of rectangular steel plate elements (2) that are sequentially connected to each other. The plate element comprises two long edges (3, 4) in the lateral direction of the conveyor belt, which are parallel with and spaced from each other. The long edge (3, 4) of a similar adjacent second plate element is connected to each long edge (3, 4). The plate element comprises two short edges (5, 6) in the longitudinal direction of the conveyor belt, which are spaced from each other by a distance corresponding to the width (L) of the conveyor belt. Each plate element (2) includes a number of holes (7) to enable the flow-through of the gas that is used in sintering. The holes (7) in the plate element (2) are grouped into essentially rectangular elongated groups of perforations (A) in the direction of the conveyor belt, the groups of perforations (A) being parallel with each other and spaced from each other by an imperforated gap (e). The holes (7) in each group of perforations (A) are grouped into a number of subgroups (B), a first imperforated area (9) being between each one of them. Between the subgroups (B) adjacent to each long edge (3, 4) of the plate element (2) and the long edge (3, 4), there is a second imperforated area (10).
Description
The application is that to be called " conveyer belt and the method for repairing this conveyer belt ", international filing date be that August 14, international application no in 2008 are that PCT/FI2008/050461, national applications number are dividing an application of 200880103015.3 application for a patent for invention to name.
Technical field
The present invention relates to the conveyer belt limiting in the preorder of claim 1.The present invention also relates to the method limiting in the preorder of claim 7.
Background technology
Continuous band sintering is used for bonding (agglomerizing) pelletizing after making fine ore pelletizingization, improves intensity and the activity of pelletizing.
As the example of belt sintering technology, can mention belt sintering stove, belt sintering stove is for the production of ferrochrome and be divided into several sequential areas, in each of these regions, has different temperature condition.Belt sintering equipment comprises conveyer belt, and this conveyer belt is the steel band of perforation.This conveyer belt is transmitted around two deflection roll as endless belt.At the front end place of stove, wet new pelletizing is fed on steel band to form the bed of number cm thick.Steel band transmits dry, the heating of pelletizing bed by stove and sintering region and arrives stable or equilibrium region, and after this pelletizing bed is further through the cooled region of order.After passing cooled region, the pelletizing of sintering leaves belt sintering equipment at afterbody.
Conveyer belt forms endless belt by order a plurality of rectangular steel plates elements connected to one another, and each steel plate element comprises two the horizontal long edges along conveyer belt.Long edge is parallel to each other and be spaced apart from each other, and similarly the long edge of adjacent the second panel element is connected to each long edge.Distance along two minor face edge each intervals of the panel element longitudinally of conveyer belt corresponding to the width of conveyer belt; In other words, panel element extends on the whole width of conveyer belt.Each panel element comprises perforation, by this perforation, for the gas of sintering, can flow through conveyer belt and to the pelletizing bed on the top of band.It is the elongate perforations group of rectangle that perforation in panel element assembles along the basic of the direction of conveyer belt, these perforation groups puncherless gap parallel to each other and spaced apart.
For example, the conveyer belt according to known technology is disclosed in patent specification FI111100B.Perforation group extends to each long edge of panel element always as substantially continuous punched areas.
The connecting welding that a problem of known technology is similar adjacent panel element is difficult, because perforation overlaps with weld seam and weld seam is inhomogeneous and continuous.When using conveyer belt, also there is the danger of bond open.In addition,, when the conveyer belt position damaged and damaged at some positions will be by built-up welding (deposition weld), carry out built-up welding and also have problems.The weld seam of heap welding plate always intersects with perforation; Therefore, the weld seam of heap welding plate will not become that do not disconnect and continuous weld seam.The structure that this makes welding difficulty and weakens conveyer belt.
Summary of the invention
The object of the invention is to eliminate above-mentioned shortcoming.
Especially, the object of the invention is to disclose a kind of conveyer structure, this structure makes always in unperforated annular region, to form connecting line and the heap weld seam of panel element.
Other object of the present invention is to disclose a kind of conveyer belt, and this conveyer belt is firmer than former, the tendency of avoiding or at least significantly reducing punched areas plastic deformation, breakage and need to repair.
Other object of the present invention is to disclose a kind of favorable method of repairing damaged conveyer belt.
Conveyer belt according to the present invention is characterised in that the feature providing in claim 1.The method according to this invention be characterised in that in addition the feature providing in claim 7.
Conveyer belt according to the present invention forms endless belt by order one group of rectangular steel plates element connected to one another, each rectangular steel plates element comprises: along two horizontal long edges of conveyer belt, described edge is parallel to each other and be spaced apart from each other, and similarly the long edge of adjacent the second panel element is connected to each long edge; With two the minor face edge longitudinally along being sent to, these two minor face edge each intervals are corresponding to the distance of the width of conveyer belt; Each panel element comprises and is used in the perforation that the gas of sintering can flow through, and the perforation in panel element assembles the elongated rectangle perforation group substantially along the direction of conveyer belt, the parallel to each other and puncherless gap of each interval of described perforation group.
According to the present invention, the perforation in each perforation group assembles a plurality of subgroups, and imperforated first area is between each subgroup.Between the subgroup and long edge at each long edge of adjoining plate element, be furnished with imperforated second area.
An advantage of the invention is, the rigidity of perforation has been improved in imperforated region, makes in conveyer belt, to avoid forming the permanent deformation such as fold.Due to imperforated region, the lateral stiffness of conveyer belt, horizontal controllability and also improving service life.In addition, heap weld seam and attachment weld can always be formed in unperforated annular region, have facilitated the quality of welding and improve weld seam.
According to the present invention, in the method, from conveyer belt, remove a part, this part comprises the subgroup that damaged area extends to its region, and the opening that the part that makes to remove stays is edge limited by not disconnecting of extending along unperforated annular region.Then, form the heap welding plate of the shape with this opening, this heap welding plate has a plurality of subgroups corresponding to the part having removed in the position substantially the same with removing those positions in part.The edge of heap welding plate is welded to the edge of opening by continuous weld.
In the embodiment of conveyer belt, perforation is evenly distributed in the surf zone of subgroup.
In the embodiment of conveyer belt, perforation is the horizontal slotted hole along conveyer belt, along the lateral arrangement of conveyer belt, embarks on journey.The end of slotted hole longitudinally interlocks along conveyer belt.
In the embodiment of conveyer belt, the width of slotted hole is about 1:5 to the ratio of its length.
In the embodiment of conveyer belt, the width of imperforated first area is greater than 5mm, preferably 20mm or larger at least.
In the embodiment of conveyer belt, the width of imperforated second area is greater than 5mm, preferably 20mm or larger at least.
