Technical field
The utility model relates to a kind of large forged back-up roll roll neck Cooling protector.
Background technology
The quenching technology of large forged back-up roll comprises heat hot process in thermal pretreatment, inductor block or the process furnace in preheating oven and spray cooling process.
Wherein, when large forged back-up roll 4 carries out heat hot process in process furnace, the roll neck 41 at two ends needs to be supported by carrying roller 5, as shown in Figure 1.Owing to being high-temperature atmosphere in process furnace burner hearth 6, and whole heat-processed needs lasting 5 ~ 9 hours, and the speed of rotation of carrying roller only has 1 ~ 22 turn/hour, therefore, the factors such as the thermal radiation in process furnace burner hearth 6 and self thermal conduction of large forged back-up roll 4 can cause large forged back-up roll 4 roll neck place temperature to raise, to such an extent as to exceed the tempering temperature of large forged back-up roll 4 conditioning heat treatment, thus roll neck can be caused to lose efficacy.
Utility model content
The purpose of this utility model is to solve the problem, the large forged back-up roll roll neck Cooling protector provide a kind of thermal radiation that can effectively intercept in process furnace burner hearth, avoiding roll neck temperature too high.
The technical scheme realizing the utility model object is: a kind of large forged back-up roll roll neck Cooling protector, and it is made up of two symmetrically arranged water-cooled bodies; Each water-cooled body includes semicircle hollow body, web plate and cooling module; Described semicircle hollow body to comprise in steel plate in the outer steel plate of the semi-cylindrical that is welded as a whole, semi-cylindrical, upper steel plate, lower steel plate, the outer steel plate of semi-circular shape, semi-circular shape steel plate in steel plate and half truncated cone-shaped;
Described web plate is weldingly fixed on the outer steel plate of described semi-cylindrical; Described cooling module comprises water inlet pipe, rising pipe and for by described water inlet pipe and the described rising pipe releasable connection rotatable connectors on the outer steel plate of described semi-cylindrical.
Described web plate is provided with 1 ~ 3.
Described web plate is provided with adjustment open holes.
The positively effect that the utility model has: large forged back-up roll roll neck Cooling protector structure of the present utility model is simple, easy to make, can repeatedly use.This roll neck Cooling protector is arranged on process furnace two ends, utilizes recirculated water to cool roll neck place, effectively can intercept the thermal radiation in process furnace burner hearth, thus avoid roll neck temperature too high, ensure that the mechanical property at roll neck place can not be damaged.

Fig. 2 is the structural representation of one of them water-cooled body of roll neck Cooling protector of the present utility model.
Fig. 3 is the right view of Fig. 2.
Fig. 4 is that B in Fig. 2 is to partial enlarged drawing.
Embodiment
Large forged back-up roll roll neck Cooling protector of the present utility model is made up of two symmetrically arranged water-cooled bodies.
The structure of one of them water-cooled body is shown in Fig. 2 and Fig. 3, and this water-cooled body comprises semicircle hollow body 1, web plate 2 and cooling module 3.
Semicircle hollow body 1 to comprise in steel plate 12 in the outer steel plate 11 of the semi-cylindrical that is welded as a whole, semi-cylindrical, upper steel plate 13, lower steel plate 14, the outer steel plate 15 of semi-circular shape, semi-circular shape steel plate 17 in steel plate 16 and half truncated cone-shaped.
Wherein, in semi-cylindrical, the length (in Fig. 3 left and right directions) of steel plate 12 is less than the outer steel plate 11 of semi-cylindrical; In semi-circular shape, the height (in Fig. 3 above-below direction) of steel plate 16 is less than the outer steel plate 15 of semi-circular shape; In half truncated cone-shaped, steel plate 17 to be weldingly fixed in semi-cylindrical in steel plate 12 and semi-circular shape between steel plate 16.Upper steel plate 13 and lower steel plate 14 are in pentagon.
In half truncated cone-shaped, the design of steel plate 17 can protect large forged back-up roll body of roll roll neck junction can not produce pit due to collision, ensure that quality product.
Web plate 2 of the present utility model is provided with two, is respectively one end and is weldingly fixed on the first web plate 21 in the middle part of the outer steel plate 15 of semi-circular shape and one end and is weldingly fixed on the outer steel plate 15 of semi-circular shape and the second web plate 22 be positioned at above the first web plate 21.Two web plates 2 are all connected (see figure 4) by bolt assembly with the back up pad 9 being fixedly mounted on process furnace two ends in use.
Adopting two web plates 2 namely can ensure, roll neck Cooling protector of the present utility model is stable is arranged on process furnace two ends.
Web plate 2 and back up pad 9 are equipped with installation adjustment hole 2-1,9-1; installation adjustment hole 2-1 length wherein on web plate 2 is 126mm; the length of the installation adjustment hole 9-1 in back up pad 9 is 360mm; web plate 2 and back up pad 9 adopt (same plane) mode connected vertically, can carry out radial and axial adjustment as required like this to roll neck Cooling protector of the present utility model.
The outer steel plate 15 of semi-circular shape is respectively equipped with water-in and water outlet, cooling-part 3 comprises water inlet pipe 31 and rising pipe 32 and rotatable connectors 33(internal thread square elbow), water inlet pipe 31 is connected respectively by the water-in on the outer steel plate 15 of rotatable connectors 33 and semi-circular shape and water outlet with rising pipe 32, thus make water coolant at semicircle hollow body 1 internal recycle, both the thermal source in large forged back-up roll heat-processed had been realized effectively to intercept in roll neck place, play protection roll neck not by the effect of heating, ensure that the body of roll is overall by the effect of heating simultaneously, prevent large forged back-up roll roll neck overtemperature, destroy roll neck place and have mechanical property.
The using method of roll neck Cooling protector of the present utility model is as follows: before large forged back-up roll enters process furnace, just need roll neck Cooling protector of the present utility model to be installed to process furnace two ends (the roll neck place between the medium-and-large-sized support roll roll neck 41 of Fig. 1 and the body of roll), high-temperature heat-resistance fibrous encapsulation is adopted between symmetrically arranged two water-cooled bodies, also high-temperature heat-resistance fibrous encapsulation is adopted between the inwall of steel plate 12 and the roll neck of large forged back-up roll in two semi-cylindrical, heat resisting brick is then adopted to fill between steel plate 11 and process furnace outside two semi-cylindrical.During installation, ensure that the semicircle hollow body 1 at process furnace two ends, web plate 2 and back up pad 41 are all in same level, then with bolt connect, fixing, make it can not slippage, finally water inlet pipe is connected with outer water tube with rising pipe, ensures cooling water circulation unimpeded.
