Abstract
The utility model discloses the composite roll production equipment, which is provided with a furnace jacket(5), an induction heating coil(3) and a protecting jacket(2) on a casting mould base(9). The bottom of the furnace jacket(5) is provided with a location hole(6), the protecting jacket(2) is arranged outside the furnace jacket(5), and the induction heating coil(3) is provided between the furnace jacket(5) and the protecting jacket(2). The design of the utility model is reasonable. Compared with other roll manufacturing installations, the composite roll production equipment has the advantage that the installation is simple, and sizes of the induction heating coil and the furnace jacket just need to be changed to produce rolls with different model numbers according to requirements; the production cost is effectively reduced; the investment is less; the production technology is simple, and the operation is easy; the production efficiency is high.
Description
Affiliated technical field
The utility model belongs to the production equipment technical field of roll, and what relate generally to is a kind of composite roll production equipment.
Background technology
Roll is the critical component of steel rolling, also is consumable accessory, and along with the raising of mill speed, the requirement of breaker roll is more and more higher, and the performance of solid roll can not satisfy needs of production, therefore, all actively carries out the Application and Development of composite roll both at home and abroad.At present, the manufacturing of composite roll can be divided into substantially: centrifugal process, continuous casting process (CPC method), electroslag remelting welding method (ESR Cladding method).
The roll of centrifugal process manufacturing improves a lot than the performance of solid roll, has also played important effect for the application of modern roll.But its centrifugal equipment shortcoming be invest too big, its technology is difficult to grasp, the rotary speed of metal mold in the time of when producing the roll of different-diameter, need determining to pour into a mould, also to determine the pouring temperature and the time of the molten iron of core in addition according to the molten iron that pours into core to the influence of binder course and transition region, the too big or too little quality that all can influence roll of the thickness of its transition zone is difficult to hold; Centrifugal process also is easy to generate component segregation.
Continuous casting process (CPC method) and electroslag remelting welding method (ESR Cladding method) are present advanced technologies, and two kinds of equipment investments are very high.The formation of CPC method binder course affects the decrease speed of roller core, and comparatively speaking, the production efficiency of CPC method is lower.ESR Cladding method is to be similar to the CPC method, only substitutes eddy-current heating with electroslag remelting, and roller core does not need precoated shet, but essential strict control reflow process, production efficiency is lower, and technology is difficult to be grasped.
Summary of the invention
The utility model proposes a kind of composite roll production equipment, can reduce the roll production cost, simplify production technology, improve the quality of products.
For achieving the above object; the technical scheme that the utility model is taked is: boiler clothing, load coil and protective sleeve are set on the casting mold base; the bottom of boiler clothing is provided with locating hole, and protective sleeve is arranged on outside the boiler clothing, is provided with load coil between boiler clothing and protective sleeve.
The utility model is reasonable in design, has compared following advantage with other roll manufacturing installations:
1, device is simple.The roll of production different model if desired, the size that only needs to change load coil and boiler clothing gets final product.
2, investment cost is low.
3, production technology is simple, easily operation.Whole process only needs roller core is heated to uniform temperature, pours into a mould then to get final product.
4, production efficiency height.
Description of drawings
The utility model accompanying drawing is a structural representation.
Among the figure, 1, cover plate, 2, protective sleeve, 3, load coil, 4, dry sand, 5, boiler clothing, 6, locating hole, 7, water inlet pipe, 8, outlet pipe, 9, the casting mold base.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in drawings, present embodiment is that boiler clothing 5, load coil 3 and protective sleeve 2 are set on casting mold base 9.Have 2/3rds dry sand and 1/3rd sodium silicate sand in the casting mold base 9, boiler clothing 5 adopts refractory material or sand mold to make, its bottom has locating hole 6, this locating hole 6 is joined with the roller core kiss, purpose is to allow the bottom of roller core imbed in the molding sand in the casting mold base 9 by the locating hole 6 of boiler clothing 5 bottoms position, and uses CO then
2Drying up (or water alcohol light dry) fixes.Load coil 3 and protective sleeve 2 all are arranged on outside the boiler clothing 5, are fixed on the casting mold base 9 by cover plate 1 up and down.Protective sleeve 2 is made after adopting molding sand to add the waterglass oven dry; load coil 3 is between boiler clothing 5 and protective sleeve 2; along boiler clothing 5 coiling settings; water inlet 7 is positioned on the casting mold base 9 with delivery port 8; leave the space of about 3-5mm between load coil 3 and the boiler clothing 5; pressure damages boiler clothing too greatly when avoiding pouring into a mould, and is filled with 4 pairs of boiler clothings 5 of dry sand and protects in this space.Present embodiment in use, ready-made roller core is put into boiler clothing 5, and the locating hole 6 that makes the bottom pass boiler clothing bottom also enters in the casting mold base 9 and positions, connecting power supply then heats 3 pairs of roller cores of load coil, after the roller core temperature reaches design temperature, cast then, watered and covered the borax insulation, continue heating a period of time, cut off the electricity supply, draw by the water inlet 7 injection cooling waters of load coil 3 and by delivery port 8 then, to be cooled finishing promptly obtains composite roll.
Claims (3)
