Abstract
The utility model discloses a fixing structure for heat insulation cotton in a heat insulation cover of a 2050 hot rolling machine, wherein, a plurality of steel strips are longitudinally and horizontally laid on heat insulation cotton blocks horizontally laid on the heat insulation cover, two ends of each steel strip are fixed at the edge of the heat insulation cover, through holes are formed at the intersections of the longitudinal and the horizontal steel strips, and bolts are inserted into the through holes and screwed on the heat insulation cover. The fixing structure can be used for reliably fastening the heat insulation cotton on the heat insulation cover, prevents the heat insulation cotton from falling off during the operation of the rolling machine, improves the rolling quality of plate blank, and prolongs the repair cycle of the heat insulation cover.
Description
Technical field
The utility model relates to the fixed structure of heat-preservation cotton in a kind of 2050 continuous hot-rolling mill stay-warm cases.
Background technology
2050 continuous hot-rolling mills are in service to reduce thermal losses in the slab rolling process by stay-warm case, on the stay-warm case by metal fixing tiling polylith heat-preservation cotton.During the milling train operation, from the process of static setting in motion, the slab nose can clash into heat-preservation cotton to slab under stay-warm case, the metal fixing of heat-preservation cotton from stay-warm case will be torn if nose is higher; Stay-warm case puts down when beginning to be incubated simultaneously, and the high temperature slab continues the metal fixing of heat-preservation cotton is toasted, and causes the metal fixing fracture, causes the heat-preservation cotton piece to come off, and has influenced the insulation of high temperature slab.
Because heat-preservation cotton comes off, must change the serious heat-preservation cotton that comes off during the milling train periodical repair, and the quantity of changing heat-preservation cotton is to determine all to change or the part is dug and repaiied according to the size of the area that comes off basically, so the quantity that the minimizing heat-preservation cotton comes off is to reduce the overhaul of the equipments load, realizes an effective way of cost efficiency.
Summary of the invention
Technical problem to be solved in the utility model provides the fixed structure of heat-preservation cotton in a kind of 2050 continuous hot-rolling mill stay-warm cases, this fixed structure can reliably be anchored on heat-preservation cotton on the stay-warm case, avoid heat-preservation cotton coming off in the milling train running, improve the rolling quality of slab, prolonged the time between overhauls(TBO) of stay-warm case.
For solving the problems of the technologies described above, the fixed structure of heat-preservation cotton comprises stay-warm case and the some heat-preservation cotton pieces that are tiled on the described stay-warm case in the utility model 2050 continuous hot-rolling mill stay-warm cases, also comprise some steel bands, described some steel bands become vertical and horizontal to be overlying on described each heat-preservation cotton piece and described stay-warm case edge is fixed at two ends, and described vertical steel band and horizontal steel band infall have through hole and penetrate bolt twists on described stay-warm case.
Be each heat-preservation cotton piece of secure fixation, be covered with a vertical steel band and a horizontal steel band on above-mentioned each heat-preservation cotton piece at least.
For making some steel band secure fixation on stay-warm case, above-mentioned some steel bands two ends are by being fixedly welded on described stay-warm case edge.
For further improving heat insulation effect, this fixed structure also comprises the chamotte layer, and described chamotte layer is coated on described some heat-preservation cotton pieces surface.
Because the fixed structure of heat-preservation cotton has adopted technique scheme in the utility model 2050 continuous hot-rolling mill stay-warm cases, be on some steel bands each heat-preservation cotton piece of becoming vertical and horizontal to be overlying on to be tiled on the stay-warm case and the stay-warm case edge is fixed at the steel band two ends, vertically steel band and laterally the steel band infall have through hole and penetrate bolt and twists on stay-warm case.This fixed structure can reliably be anchored on heat-preservation cotton on the stay-warm case, avoids heat-preservation cotton coming off in the milling train running, has improved the rolling quality of slab, has prolonged the time between overhauls(TBO) of stay-warm case.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the schematic diagram of heat-preservation cotton fixed structure in the utility model 2050 continuous hot-rolling mill stay-warm cases,
Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
As depicted in figs. 1 and 2, the fixed structure of heat-preservation cotton comprises stay-warm case 1 and the some heat-preservation cotton pieces 2 that are tiled on the described stay-warm case 1 in the utility model 2050 continuous hot-rolling mill stay-warm cases, also comprise some steel bands 3 and 4, described some steel bands 3 are overlying on described each heat-preservation cotton piece 2 with 4 one-tenth vertical and horizontal and described stay-warm case 1 edge is fixed at two ends, and described vertical steel band 3 and horizontal steel band 4 infalls have through hole 5 and penetrate bolt 6 twists on described stay-warm case 1.
Be each heat-preservation cotton piece of secure fixation, be covered with a vertical steel band 3 and a horizontal steel band 4 on above-mentioned each heat-preservation cotton piece 2 at least.
For making some steel band secure fixation on stay-warm case, above-mentioned some steel bands 3 and 4 two ends are by being fixedly welded on described stay-warm case 1 edge.
For further improving heat insulation effect, this fixed structure also comprises chamotte layer 7, and described chamotte layer 7 is coated on described some heat-preservation cotton pieces 2 surfaces.
This fixed structure is easy to make, with low cost, steel band can be selected the good material of heat resistance for use, under the prerequisite that does not change the original planform of stay-warm case, realize the effectively fixing of heat-preservation cotton piece by steel band, solved present 2050 milling trains and changed the repair rate problem of higher, and then improved the heat insulation effect of milling train stay-warm case owing to the heat-preservation cotton piece comes off, prolong the time between overhauls(TBO) of stay-warm case, reduced the cost of overhaul of milling train.
