Abstract
The utility model relates to the equipment of a normalizing furnace in the production of steel rolling, in particular to a water cooling roller of a normalizing furnace. According to the technical scheme of the utility model, the water cooling roller of the normalizing furnace comprises a hollow shaft and a roller sleeve, wherein the roller sleeve is sleeved at an outer ring at the middle part of the hollow shaft, one end of the hollow shaft is provided with a rotary joint, and the other end of the hollow shaft is provided with a shaft head. The water cooling roller of the normalizing furnace is characterized in that a spiral guide vane is arranged in the hollow shaft. The utility model has the advantages that the spiral guide vane is arranged in the hollow shaft, an unordered water flow process is compelled to be changed into an ordered uniform process, cooling water contacts with the inner surface of the hollow shaft fully, the temperature difference of water flowing through the local inner section of the hollow shaft is effectively improved, axial bending caused by a radial temperature difference is thoroughly eliminated, and the service life of a furnace roller is prolonged.
Description
Technical field
The utility model relates to the equipment of normalizing furnace in a kind of steel rolling production, relates in particular to a kind of normalizing furnace water cooled rolls.
Background technology
The normalizing furnace water cooled rolls is mainly used in the stainless steel plate of moderate thickness heat treatment furnace.This furnace roller is nickelic, the chromium heat-resisting steel material, and is in thick stainless steel plate in high temperature (more than the 1200 °) conveying for a long time.Because working condition is abominable, hot strength requires high, and the body of roll easily produces other defects such as bending, and influence that steel plate carries in stove stable and the serious accident of hitting furnace wall happen occasionally.The roller buckling problem of especially middle heat section is of common occurrence, and to scrap the ratio that accounts for quite high because of the furnace roller bending causes.
We have adopted a lot of measures to want to solve the buckling problem of water cooled rolls in the normalizing furnace.We it has been generally acknowledged that two reasons for the generation of furnace roller buckling problem in the past: at first be that user's use is wrong, as cut off the water supply, at high temperature stop operating, cause roll bending.Next is a manufacturing process, thinks that furnace roller at high temperature uses, and to making part without ageing treatment, does not eliminate as welding process stress, with regard to processed finished products, meets high temperature stress release during use and causes bending.As time goes on, the user uses strict working specification, and our manufacturing process is also day by day ripe, but body of roll buckling problem does not have change yet.Trace it to its cause, may be relevant with water-cooling structure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and water-cooling structure is transformed completely, and once and for all solves the furnace roller buckling problem.Example has adopted new water-cooling structure furnace roller in certain stainless steel Heavy Plate Plant, uses from 2005 never to take place last year to cause stopping production or more renewing furnace roller because of the furnace roller bending.
According to the technical solution of the utility model, described normalizing furnace water cooled rolls comprises tubular shaft and roller shell; described roller shell is placed on the outer ring at tubular shaft middle part; end at tubular shaft is provided with swivel joint, and the other end of tubular shaft is a spindle nose, it is characterized in that: the spirally-guided blade is set in the described tubular shaft.
Form cavity between described roller shell and the tubular shaft; The two ends of described roller shell are provided with first end plate, the 4th end plate respectively; Between described first end plate and the tubular shaft key is set; A side of first end plate is provided with second end plate in described cavity; A side of the 4th end plate is provided with the 3rd end plate in described cavity.
Filling ceramic insulating material in the described cavity.
Described first end plate is a cylindrical body, is collar flange on the top of first end plate; Described second end plate, the 3rd end plate, the 4th end plate are ring bodies.
Water inlet pipe, rising pipe are set in the described swivel joint.
The utility model has the advantages that: the spirally-guided blade is set in tubular shaft, force unordered flowing water to be in order even process, water coolant fully contacts with the tubular shaft internal surface, effectively improve the temperature difference in current cross section in the tubular shaft part, thoroughly eliminate, prolonged the work-ing life of furnace roller because of radial temperature difference causes axial bending.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, the normalizing furnace water cooled rolls comprises tubular shaft 1 and is placed on the roller shell 5 of tubular shaft 1 outer ring, at an end of tubular shaft 1 swivel joint 10 is set, and the other end of tubular shaft 1 is a spindle nose 8; In the described tubular shaft 1 spirally-guided blade 9 is set.
Form cavity between described roller shell 5 and the tubular shaft 1, filling ceramic insulating material in the cavity.The two ends of described roller shell 5 are provided with first end plate 3, the 4th end plate 7 respectively; Between described first end plate 3 and the tubular shaft 1 key 2 is set, in order to fix first end plate 3; A side of first end plate 3 is provided with second end plate 4 in described cavity; A side of the 4th end plate 7 is provided with the 3rd end plate 6 in described cavity.Described first end plate 3 is a cylindrical body, forms collar flange on the top of first end plate 3; Described second end plate 4, the 3rd end plate 6, the 4th end plate 7 are ring bodies.The fixedly effect of roller shell 5 is played in the setting of four end plates, and simultaneously the collar flange of first end plate 3 and the 4th end plate 7 also play ceramic insulating material is sealed in effect in the cavity.
In the described swivel joint 10 water inlet pipe, rising pipe are set.
During work, water coolant flows into tubular shaft 1 from the water inlet pipe of swivel joint 10, and the water that is heated then returns swivel joint 10, flows out from rising pipe.
Existing water cooled rolls is after water coolant flows into tubular shaft 1, flow out when getting back to swivel joint 10 from right-hand member, water (flow) direction is randomness, when the body of roll is subjected to hyperthermia radiation to tubular shaft 1, because tubular shaft 1 is influenced by unordered water coolant, can cause uneven cooling, cause tubular shaft 1 inequality of being heated, cause STRESS VARIATION and produce bending.
The utility model increases spirally-guided blade 9 in tubular shaft 1, force unordered flowing water to be in order even process, and water coolant fully contacts with tubular shaft 1 internal surface, effectively improves the temperature difference in current cross section in the tubular shaft part.Can continue cumulative height though water coolant flows to the left end water temperature from right-hand member, it can produce the axial stress elongation, and thoroughly elimination causes axial bending because of radial temperature difference.
