Abstract
The utility model relates to a roll used in the steel rolling machinery. The utility model is characterized in that a core axle 5 is made from a discarded roll; more than one pair of key ways is processed on the corresponding positions on both sides of a core axle and a roll sleeve 4; metallic keys can be arranged in the key ways; slag welding, molten steel casting and molten iron casting can be used for filling the key way positions to fix the core axle 5 and the roll sleeve 4.
Description
The utility model relates to a kind of roll that uses in rolling machinery.
In rolling machinery, roll is one of most important parts, the production cost height, and consumption is big, especially produces the iron and steel enterprise of cut deal material, because the quantity that operation roll of mill consumes is big, thereby the cost of its product is improved.Current, a lot of R﹠D institutions and manufacturer have dropped into great amount of manpower and material resources for the high-quality roll of exploitation low price.
Abroad, have only and use the backing roll that adds cover on the minority cold-strip milling train, this roll all is hot charging usually, because the magnitude of interference is difficult to grasp, not the roller shell cracking after installing, be exactly after using a period of time on the milling train, roller shell rotates and axial motion, thereby seldom uses.
The purpose of this utility model is to provide a kind of composite roll, and this roll adopts scraps roll manufacturing mandrel, thereby greatly reduces manufacturing cost, and anufacturability is good, the functional reliability height.
The purpose of this utility model is achieved in that utilizes the roll of scrapping to make mandrel 5, strong groove more than processing on mandrel 5 and the position, roller shell 4 corresponding both sides is a pair of, in the keyway metallic bond can be installed, also can fill and use molten steel with electroslag welding, the molten iron casting is full of strong groove location mandrel 5 and axle sleeve 4 is fixed, use electroslag welding method to fill that strong groove is fixed and to adopt casting molten steel, iron to be full of strong groove fixing, keyway shape outside size on mandrel 5 and the roller shell 4 is big, the inside size is little, concentrates to avoid stress.
Adopt metallic bond to fix, should between bearing inner sleeve and roller shell, install and fix cover.
Drawings and Examples:
Fig. 1 overlaps the composite roll schematic diagram for fixing strong the adding of band
The composite roll schematic diagram of Fig. 2 for fixing with the molten steel casting keyway
Fig. 3 is a composite roll roller shell schematic diagram
Fig. 4 is a composite roll mandrel schematic diagram
Embodiment 1: accompanying drawing 1 is disclosed to be an embodiment of the present utility model, mandrel: Φ 755 * 3454mm, roller shell: (Φ 755 * Φ 965 * 3454mm) is worked into the size of requirement, keyseat then with scrapping roll with mandrel 5 to internal diameter * external diameter * length.The hot charging that the roller shell 4 that processing is over is heated in heating furnace requires temperature, again mandrel 5 and roller shell 4 is carried out hot charging, again key is packed in the strong groove afterwards, during use, in axle sleeve 1,7 with roller shell 4 between install and fix and overlap 2,6 and prevent axial motion.
Embodiment 2: accompanying drawing 2 is disclosed to be another embodiment of the present utility model, mandrel: mandrel: Φ 755 * 3454mm, roller shell: (Φ 755 * Φ 965 * 3454mm) is worked into the size of requirement, keyseat then with scrapping roll with mandrel 5 to internal diameter * external diameter * length.The roller shell 4 that processing is over is heated to the temperature that hot charging requires in heating furnace, again mandrel 5 and roller shell 4 are carried out hot charging, be full of keyway with molten steel or molten iron then, the surface and the end face of last breaker roll carry out machining and surface treatment, to improve the wearability and the service life of roll.
The roll that the utility model utilization is scrapped is made roller core, greatly reduces the roll manufacturing cost.This composite roll can be used for hot rolled steel plate mill working roll and hot-rolled and cold-rolled cut deal mill backing roll, also can be used for conticaster and make the straightening roller.Thereby have very big social benefit and an economic benefit.
Claims (2)
1, a kind of composite roll, form by roller shell 4, mandrel 5 etc., it is characterized in that: utilize and scrap roll manufacturing mandrel 5, keyway more than processing on mandrel 5 and the position, roller shell 4 corresponding both sides is a pair of, in the keyway metallic bond can be installed, also can be full of the keyway position mandrel 5 and roller shell 4 are fixed with the electroslag welding filling with molten steel, molten iron casting.
2, composite roll according to claim 1, it is characterized in that: use electroslag welding method filling keyway is fixed and is adopted casting molten steel, molten iron to be full of the fixing composite roll of keyway, keyway shape outside size on mandrel 5 and the roller shell 4, the inside size is big, and its transition portion is the transition of Da Yuan angle.
