The utility model provides a heat roller, and the heat roller realizes a connection of an inner cavity of the heat roller and an outer wall conical surface of the heat roller through advanced diffusion welding technology, a plurality of inclining and cylindrical liquid cavities are arranged on a sidewall conical surface of the roller body, a rotation radius of an axis of the cylindrical liquid cavity in an evaporation section is greater than the rotation radius of the axis of the cylindrical liquid cavity in an condensing section, a novel conical surface structure provides an needed inclination angle for realizing heat transmission backflow, heat is transmitted from the evaporation section to the condensing section through evaporation of liquid in the cylindrical liquid cavities, and liquid backflows from the condensing section to the evaporation section by a component force of centrifugal force, so evaporation and condensation backflow function of the cylindrical liquid cavities is realized. Heat roller in the prior art has disadvantages of large heat transfer thermal resistance, low filling ratio, poor isothermality, complex processing, and the like, the novel conical surface structure hot roller solves problems existing in the prior art, and has the advantages of large heat transfer area, high filling ratio, large backflow power, simple manufacturing process, good heat transfer effect, good isothermality, low cost, and the like.

Description

A kind of hot-rolling

Technical field

The utility model relates to the roll extrusion instrument field, special relates to a kind of hot-rolling.

Background technology

In the prior art; Making hot-rolling is the direction punching in bar upper edge and hot-rolling rotating shaft level, will buy heat pipe made of copper then and insert in the hole, and realizes encapsulation at last; Be provided with return-flow structure in the heat pipe made of copper; Make the steam of evaporator section be back to condensation segment, the current direction evaporator section of condensation segment, this manufacturing process is comparatively complicated.

Hot-rolling of the prior art manufacturing process in manufacture process is complicated, and cost is higher.

The utility model content

The purpose of the utility model is in manufacture process, to realize complex process to the hot-rolling that exists in the prior art; The cost problem of higher; A kind of hot-rolling is provided; Be provided with the column fluid chamber in the sidewall of hot-rolling, the axis of column fluid chamber is in the radius of turn of the evaporator section radius of turn greater than condensation segment.

Further, the axis of column fluid chamber and hot-rolling rotating shaft are positioned at same plane.

Further, the inner chamber of hot-rolling and outer wall are taper shape.

Further, the quantity of column fluid chamber is a plurality of.

Further, the liquid of dress is water in the column fluid chamber.

Further, the cross section of column fluid chamber is the groove shape.Cross section in the present embodiment is meant, with the vertical plane of hot-rolling rotating shaft.

Further, the column fluid chamber of groove shape evenly distributes in the sidewall of rod body.

Further, the column fluid chamber surfacing of hot-rolling is the material that does not react with column liquid intracavity liquid.

Because column fluid chamber and rotating shaft have certain inclination angle; When hot-rolling when rotating at a high speed, the evaporator section heated liquid becomes gas and reaches condensation segment to heat by evaporator section, gas becomes liquid after the condensation segment condensation; Liquid is back to evaporator section by condensation segment under the effect of centrifugal force component; Thereby realize the gas-liquid circulation, constantly pass to outer wall to heat by inner chamber, thereby make outer wall isothermal better performances; Manufacturing process becomes simply, and cost also reduces greatly, heat transfer efficiency also is improved greatly.

Fig. 2 representes the sectional side view of the embodiment hot-rolling that the utility model provides.

The specific embodiment

Below in conjunction with Figure of description the utility model preferred embodiment is described, the sidewall of hot-rolling is divided into inwall and outer wall, and inwall and outer wall all have a certain degree with rotating shaft, is used for guaranteeing liquid in the fluid chamber required inclination angle of refluxing.And the hot-rolling inwall is to be connected through technological realization of advanced person's Diffusion Welding with outer wall; The sidewall of hot-rolling has a plurality of fluid chamber to be used for transmitting heat; And can not gang up each other between fluid chamber and the fluid chamber; The rotation hot-rolling can produce bigger pressure when operating temperature is rotated at a high speed, advanced Diffusion Welding technology can not only realize that large tracts of land welds simultaneously, and Diffusion Welding can guarantee the design strength requirement of fluid chamber.Like Fig. 1, shown in 2; Be provided with column fluid chamber 2 in the sidewall 1 of hot-rolling; The axis of column fluid chamber and hot-rolling rotating shaft have a certain degree; The axis of column fluid chamber is in the radius of turn of the evaporator section radius of turn greater than condensation segment, and promptly the axis of column fluid chamber is in the evaporator section 21 of column fluid chamber 2 distance H 1 apart from the hot-rolling rotating shaft, greater than the axis of column fluid chamber in the condensation segment 22 of column fluid chamber 2 distance H 2 apart from the hot-rolling rotating shaft.During work, hot-rolling is in high temperature and rotation at a high speed, because H1 is greater than H2; Liquid in the column fluid chamber 2 is water for example, will under action of centrifugal force, flow to column fluid chamber 2 evaporator sections 11; Because the inner chamber 3 of evaporator section 11 next-door neighbour's hot-rollings is equipped with thermal source in the inner chamber 3, the heat of thermal source can be transmitted to the evaporator section 11 of column fluid chamber 2 through sidewall 1; Water becomes steam after evaporator section 11 is heated; Along with the increase of steam, steam will be with heat to be passed to roll body condensation segment 22, and water is met the water of cold back liquefy at condensation segment 22.Above process can constantly move in circles; The hot-rolling of rotation leans on the liquid in the column fluid chamber to realize heat transmission through evaporating so at a high speed; Become liquid state again through condensation again, this hot-rolling manufacturing process is simple, with low cost, the good and heat transfer efficiency advantages of higher of hot-rolling outer wall isothermal.

For easy to process, can adopt the axis and the hot-rolling rotating shaft structure at grade of column fluid chamber.

The inner chamber and the outer wall of hot-rolling are taper shape.

The quantity of column fluid chamber can be a plurality of.

The liquid of dress can be water in the column fluid chamber, or other liquid heat-conducting medium.

The cross section of column fluid chamber is the groove shape.Cross section in the present embodiment is meant, with the vertical plane of hot-rolling rotating shaft.

The column fluid chamber of groove shape evenly distributes in the sidewall of rod body.

The column fluid chamber surfacing of hot-rolling is the material that does not react with column liquid intracavity liquid.

What should explain at last is: above embodiment only in order to the explanation the utility model technical scheme but not limit it; Although the utility model has been carried out detailed explanation with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical scheme of the utility model, also can not make amended technical scheme break away from the spirit and the scope of the utility model technical scheme and these are revised or be equal to replacement.
