Method for fitting or retrofitting a sinter cooler

A method for fitting a sinter cooler, which sinter cooler comprises a cooler grate chain with an endless chain of cooler cars, each cooler car having a front edge and a rear edge, the method comprising, for at least one cooler car:

• installing a lamella grate for holding sinter material and allowing air flow through the grate so that a support structure is connected to the cooler car and a plurality of lamellae are supported by and individually movable with respect to the support structure during operation of the sinter cooler, and are disposed to allow air flow between neighbouring lamellae, wherein the support structure comprises at least one support element disposed underneath the plurality of lamellae to support the plurality of lamellae, and at least one downholder that is adapted to limit an upward motion of at least one lamella is installed such that at least a portion of the downholder is disposed above the at least one lamella (12), and wherein the support element has an upper contour that at least partially corresponds to a profile of the lamellae.

A method for retrofitting a sinter cooler, which sinter cooler comprises a cooler grate chain with an endless chain of cooler cars, each cooler car having a front edge, a rear edge and a rigid grate for holding sinter material and allowing air flow through the rigid grate, the method comprising, for at least one cooler car:

• removing the rigid grate;
• and
• installing a lamella grate so that a support structure is connected to the cooler car and a plurality of lamellae are supported by and individually movable with respect to the support structure during operation of the sinter cooler, and are disposed to allow air flow between neighbouring lamellae, wherein the support structure comprises at least one support element disposed underneath the plurality of lamellae to support the plurality of lamellae, and at least one downholder that is adapted to limit an upward motion of at least one lamella is installed such that at least a portion of the downholder is disposed above the at least one lamella, and wherein the support element has an upper contour that at least partially corresponds to a profile of the lamellae.
