Abstract
The utility model relates to a laminar flow cooling roller, which comprises a driving unit, a transmission joint, shaft frames, support plates, a cooling roller main body and an inner cavity, wherein the cooling roller main body is of a cylindrical structure inside which a coaxial cavity is formed; the cooling roller main body is arranged horizontally and transversely; the shaft frames are coaxially arranged at the two ends of the cooling roller main body; one end of the cooling roller extends out of the shaft frames, and the driving unit is coaxially arranged on the end part of the cooling roller; the driving unit is connected with the cooling roller main body through the transmission joint; a metallurgy bonding layer is coaxially attached to the outside of the cooling roller main body; a threaded layer is uniformly formed between the metallurgy bonding layer and the cooling roller main body. The metallurgy bonding layer of about 0.05-0.1 millimeter is formed on the surface of the cooling roller by dense metal crystal structures formed by an alloy powder coating, and the bonding strength is about 400MPa. The laminar flow cooling roller is high in impact resistance, wear resistance and corrosion resistance, is in the profile of a mirror face, and has long service life.
Description
Technical field
The utility model belongs to heavy duty equipment field, especially a kind of laminar flow chill roll.
Background technology
Laminar flow chill roll is carried with laminar flow cooling in finish rolling with between batching to finished strip at hot rolling mill, hot rolling conveying roller road should bear the shock loading of finished strip, simultaneously there is again certain bond strength and ensures the polishing machine of roller-way, under the effect of cooling water spray, also to bear stress alternation (cold and hot fatigue) and part and be pressed into load, the effect of contact slide load.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of structural strength is high, shock resistance good, the laminar flow chill roll of wear-and corrosion-resistant, long service life.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of laminar flow chill roll, comprise drive train, transmission joint, pedestal, gripper shoe, chill roll main body and inner chamber, chill roll main body is the cylinder barrel shaped structure that an inside is shaped with coaxial cavity, chill roll main body horizontal cross arranges, all be coaxially installed with a pedestal at chill roll main body two ends, one end of chill roll is stretched out pedestal and is coaxially installed with a drive train in chill roll end, between this drive train and chill roll main body, save and be connected by transmission, it is characterized in that: chill roll main body is outward coaxially all with a metallurgical bonding layer; The uniform screw thread layer that is shaped with between described metallurgical bonding layer and chill roll main body.
And the thickness of described metallurgical bonding layer is 0.05-0.1mm.
Advantage of the present utility model and good effect are:
Alloy powder coating of the present utility model forms fine and close metallic crystal and is organized in the about 0.05-0.1mm of chill roll surface formation
Metallurgical bonding layer, the about 400MPa of its bond strength, shock resistance is better, wear-resisting, corrosion-resistant, outward appearance is minute surface, and long service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A portion partial enlarged drawing in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of laminar flow chill roll, comprise drive train 1, transmission joint 2, pedestal 3, gripper shoe 4, chill roll main body 5 and inner chamber 7, chill roll main body 5 is the cylinder barrel shaped structure that an inside is shaped with coaxial cavity 7, chill roll main body horizontal cross arranges, all be coaxially installed with a pedestal 3 at chill roll main body two ends, one end of chill roll is stretched out pedestal and is coaxially installed with a drive train 1 in chill roll end, saves 2 be connected between this drive train and chill roll main body by transmission.
Innovative point of the present utility model is:
Chill roll main body is outer coaxial all with a metallurgical bonding layer 6 from dissolubility alloy powder coating formation 0.05-0.1mm, and the shock resistance of this metallurgical bonding layer is better, wear-resisting, corrosion resistance and good.
In order to strengthen the main stability of wear-resistant coating, the uniform screw thread layer 8 that is shaped with between described metallurgical bonding layer and chill roll main body.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the utility model and claims, various replacements, variation and amendment are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
