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
Technical field
The present invention relates to the conveyer belt that limits in the preorder of claim 1.The present invention also relates to the method that limits in the preorder of claim 7.
Background technology
The continuous band sintering is used for bonding (agglomerizing) pelletizing after making the fine ore pelletizingization, improve the intensity and the activity of pelletizing.
As the example of belt sintering technology, can mention the belt sintering furnace, the belt sintering furnace is used to produce ferrochrome and is divided into several sequential areas, has different temperature condition in each of these zones.The belt agglomerating plant 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 the steel band to form the bed of number cm thick.Steel band transmits the pelletizing bed to be stablized or equilibrium region by drying, heating and sintering zone and the arrival of stove, and after this pelletizing bed further passes the cooled region of order.After passing cooled region, the pelletizing of sintering leaves the belt agglomerating plant at afterbody.
Conveyer belt forms the 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 second panel element is connected to each long edge.Along two minor face edge each intervals of the panel element longitudinally of conveyer belt distance 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, and by this perforation, the gas that is used for sintering can flow through conveyer belt and the pelletizing bed to the top of band.Perforation in the panel element assembles along the direction of conveyer belt basic and is the elongate perforations group of rectangle, these perforation groups puncherless gap parallel to each other and spaced apart.
For example, conveyer belt according to known technology is disclosed in patent specification FI 111100B.The perforation group extends to each long edge of panel element always as continuous basically punched areas.
The connection welding that a problem of known technology is similar adjacent panels 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 built-up welding plate always intersects with perforation; Therefore, the weld seam of built-up welding plate will not become that do not disconnect and continuous weld seam.This makes that welding is difficult and the structure of the conveyer belt that weakens.
Summary of the invention
The objective of the invention is to eliminate above-mentioned shortcoming.
Especially, the objective of the invention is to disclose a kind of conveyer structure, this structure makes the connecting line and the built-up welding that can always form panel element in unperforated annular region stitch.
Other purpose 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 purpose 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 that provides in the claim 1.The method according to this invention be characterised in that the feature that provides in the claim 7 in addition.
Conveyer belt according to the present invention forms the 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 second panel element is connected to each long edge; With two minor face edge longitudinally that the edge is sent to, these two minor face edge each intervals are corresponding to the distance of the width of conveyer belt; Each panel element comprises the perforation that the gas that is used in sintering can flow through, and the perforation in the panel element assembles the elongated basically rectangle perforation group 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 son groups, and imperforated first area is between each son group.Between the child group and long edge at each long edge of adjoining plate element, be furnished with imperforated second area.
An advantage of the invention is that the rigidity of perforation has been improved in imperforated zone, make and in conveyer belt, avoid forming permanent deformation such as fold.Because imperforated zone, the lateral stiffness of conveyer belt, horizontal controllability and also improving service life.In addition, built-up welding seam and attachment weld can always be formed in the unperforated annular region, have made things convenient for the quality of welding and improve weld seam.
According to the present invention, in the method, remove a part from conveyer belt, this part comprises the child group that damaged zone extends to its zone, and the opening that the feasible part that removes stays is edge limited by the not disconnection of extending along unperforated annular region.Then, form the built-up welding plate of shape with this opening, this built-up welding plate with remove part in substantially the same position, those positions in have corresponding to a plurality of sons of the part that has removed and organize.The edge of built-up 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 son group.
In the embodiment of conveyer belt, perforation is the horizontal slotted hole along conveyer belt, embarks on journey along the lateral arrangement of conveyer belt.The end of slotted hole vertically 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 bigger at least.
In the embodiment of conveyer belt, the width of imperforated second area is greater than 5mm, preferably 20mm or bigger at least.
