Description
Technical field
The present invention relates to the method for a kind of slide mill maintenance, specifically a kind of slip ring to slide mill carries out online method of repairing.
Background technology
Slide mill is mainly used in cement production enterprise, for the grinding of clinker.At present, after slide mill Long-Time Service, often can cause distortion because of reasons such as wear smooth ring cracking in webs.Slip ring due to slide mill is welded on grinding cylinder, eliminates welding stress and use after special purpose machine tool grinding by heat treatment, such as: the slip ring width at least 600mm of φ 4.2 × 13m slide mill; Thickness about 50mm, once slip ring distortion, traditional method for maintaining is: within deflection (Site Detection circular runout value)≤2mm, utilizes welding to support the methods such as adjustment or manual polishing and repairs, its effect is undesirable, is only generally to maintain to run; For deflection (Site Detection circular runout value) more than > 2mm's, general is all return manufactory to carry out repair process, its method processing time is long, usually about need with 3 months, cost is large, add production cost significantly, cause the waste of a large amount of man power and material simultaneously, even have influence on market management.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of slip ring to slide mill and carry out online method of repairing, the method is repaired at the scene, ensure repairing effect, processing time shortens greatly, avoids and transports back and forth, significantly reduces production cost and enhances productivity simultaneously.
To achieve these goals, a kind of slip ring to slide mill of the present invention carries out online method of repairing, and comprises the following steps:
A () be welding operation platform based on slide shoe bearing civil engineering platform;
(b) slow-speed slide mill, evenly divide 3-4 some amesdial to carry out measurement to find out deformation values at slip ring and holder watt contact surface, and deformation values that whole slip ring surface is surveyed marked off deformed region, namely the raised or sunken size of whole slip ring circumferential surface made a mark; Slip ring is divided into 6 ~ 8 equal portions amesdials and measures its slip ring linearity, with the minimum place of straightness error value for basis of reference point;
C () installs equipment for grinding, support is fixed, centering, and the water detection of equipment for grinding bed piece is put down, and bistrique driving wheel is adjusted and slip ring axis being parallel;
D () is according to measurement markers, reference said reference point in step (b), on bistrique driving wheel, abrasive band contacts with slip ring, by machine tool feed, to being out of shape, raised zones peak is roughly ground successively, partly fine grinding, fine grinding, polishing, wherein: corase grind selection 30 ~ 60 object abrasive band, abrasive band width >=100mm, belt wheel revolution: control at 700 ~ 1100rpm according to slip ring material and case hardness; Carry out half fine grinding when grinding driving wheel and slip ring contact surface >=80%, select 80 ~ 150 object abrasive bands, abrasive belt wheel revolution controls at 1000 ~ 1200rpm; Refine when grinding driving wheel and slip ring contact surface >=95%, select the abrasive band of more than 200 orders, abrasive belt wheel revolution controls at 1200 ~ 1500rpm; During slip ring circularity≤0.4mm, grinding reparation completes, and carries out polishing with polishing abrasive belt, makes slip ring roughness reach standard-required;
E the holder watt of () scraping crawler shoe, ensures slip ring and asks the contact zone of tiling to form continuous uniform the contact zones distributed, make a holder watt Bearing pattern be no less than 2 point/10 × 10mm2.
As preferably, in step (d), roughly grind selection 50 object abrasive band, abrasive band width 110mm, belt wheel revolution: 900rpm; Half fine grinding, selects 120 object abrasive bands, abrasive belt wheel revolution 1100rpm; Fine grinding, selects 220 order abrasive bands, abrasive belt wheel revolution 1300rpm.
Sliding crawler mill slip ring is the core position that slide mill runs, be easy to wearing and tearing, distortion, to compare traditional restorative procedure, the present invention installs equipment for grinding at the scene, grinding reparation is carried out to sliding crawler mill slip ring, equipment for grinding bistrique selects abrasive band, sbrasive belt grinding is except having the same swiping of emery wheel and shear action, make it to produce plastic deformation, chilling layer change and top layer in addition to tear, and owing to rubbing, contact point temperature is raised, and the Thermoplastic flow caused waits comprehensive function, thus grinding surface quality is better, ensure that repairing effect; In addition the method does not need to return manufactory and changes distortion slip ring end grinding cylinder and upper special purpose machine tool grinding process, and the processing time shortens greatly, avoid and transport back and forth, significantly reduces production cost and enhances productivity simultaneously.
Detailed description of the invention
The invention will be further described below.
A kind of slip ring to slide mill of the present invention carries out online method of repairing, and comprises the following steps:
A () be welding operation platform based on slide shoe bearing civil engineering platform;
(b) slow-speed slide mill, evenly divide 3-4 some amesdial to carry out measurement to find out deformation values at slip ring and holder watt contact surface, and deformation values that whole slip ring surface is surveyed marked off deformed region, namely the raised or sunken size of whole slip ring circumferential surface made a mark; Slip ring is divided into 6 ~ 8 equal portions amesdials and measures its slip ring linearity, with the minimum place of straightness error value for basis of reference point;
C () installs equipment for grinding, support is fixed, centering, and the water detection of equipment for grinding bed piece is put down, and bistrique driving wheel is adjusted and slip ring axis being parallel;
