Problems solved by technology
[0003] After long-term use, the sections of the inner and outer curves are worn to varying degrees, and the uneven deformation of the curved rails in each section accelerates the deformation and wear of the curved rails
[0004] like figure 1 As shown in , when the wheel of the platform turns upwards after entering the curve, the friction between the wheel and the curve changes from the original rolling friction to the sliding friction, resulting in the wear of the curve
In severe cases, it will affect the safe operation of the trolley and cause deviation
If it is replaced as a whole, the cost is too high, and the maintenance time is too long, usually 10-20 days

Abstract
The invention discloses a sintering machine head curve repair technology. A sintering machine head curve comprises a curve base, an outer curve and an inner curve, the outer curve and the inner curve form a trolley bend, and trolley guiding elements move in the trolley bend. The repair technology includes repairing of surface abrasion of the trolley bend and crack processing between the trolley bend and the curve base, wherein a method of layered surfacing of multi composite metal is adopted for the repairing of the surface abrasion of the trolley bend. According to the technology, a trolley track can be repaired to restore to original size and strength to meet the need of production by combining actual abrasion, base material component performance and working conditions and adopting a mode that layered surfacing of the multi composite metal is combined with track replacement; the situations that a welding surface strips, welding deformation is large and an original installation form is affected are avoided, the problems of off-tracking and the like of the trolley are solved, and cost and maintenance time are greatly lowered.
Description
technical field [0001] The invention belongs to the technical field of metallurgical industry production, and relates to the equipment maintenance technology of the belt sintering machine, more specifically, the invention relates to a sintering machine head bend repair process. Background technique [0002] The head curve of the sintering machine in the iron and steel plant is an important part of the belt sintering machine. It is divided into two parts, the inner and the outer curve, which are mainly used for the upward turning of the return trolley. Generally, the trolley curve is spliced into an approximate arc by three sections of curved rails, which is convenient for the trolley to slide in the inner and outer curves. [0003] After long-term use, the sections of the inner and outer curves are worn to varying degrees, and the uneven deformation of the curved rails in each section accelerates the deformation and wear of the curved rails. [0004] Such as figure 1 As ...
