Abstract
The invention discloses a high temperature and wear resistant double-layer composite hearth roll, which comprises a roller and roll shafts connected to both ends of the roller. The roll shafts are inserted into the ends of the roller to form cooperation and fixed connection. The roller is a double-layer composite cylinder, which is formed by compounding of an inner alloy layer and an outer quartz ceramic layer covering the alloy layer. Further improvements lie in that: two positioning pins radially running through cooperating parts of the roller and the roll shafts are disposed at the cooperating parts of the roller and the roll shafts, and one of the positioning pins partially runs through the other positioning pin. The double-layer composite hearth roll provided by the invention has the characteristics of high strength, high temperature resistance, low thermal expansion, good chemical stability, stable high temperature performance, no deformation, smooth and delicate surface, and good wear resistance, etc., the problems of roll surface oxidation and furnace roll nodulation are well solved, and loosening and peeling phenomena cannot come into being. The roller and the roll shafts are in reliable connection, and the connection strength is high, so that the double-layer composite hearth roll provided by the invention has high structural strength.
Description
Technical field
The present invention relates to a kind of bottom roller of annealing oven.
Background technology
Bottom roller of annealing oven comprises roller, is connected to the roll shaft at roller two ends, and roll shaft inserts roller end, forms and coordinates and adopt welding process to be fixedly connected with.The furnace bottom roll roller of prior art is generally the individual layer tube structure of being made by heat-resisting alloy steel, now also have and adopt the double-layer barrel structure that covers graphite carbon sleeve or ceramic coating on refractory alloy steel cylinder, but phenomenon, the quality product that impact is produced and the normal productions such as the furnace bottom roll of these several structures all can occur roll surface oxidation, furnace roller dross, loosens and peel off.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of solution roll surface oxidation, furnace roller dross problem are provided, can not produce high temperature resistant, the Wear-resistant double-layered composite furnace bottom roller of loose and peeling phenomenon.
The present invention is achieved through the following technical solutions technical object.
High temperature resistant, Wear-resistant double-layered composite furnace bottom roller, comprise roller, be connected to the roll shaft at roller two ends; Described roll shaft inserts roller end, forms and coordinates and be fixedly connected with; Its improvements are: described roller is two-layer compound cylindrical shell, by the alloy layer of internal layer with cover outer field quartz-ceramics layer and be composited.
The present invention further improves and is: described roller, roll shaft matching part are provided with two alignment pin that radially run through roller, roll shaft matching part, and an alignment pin wherein partly runs through another root alignment pin.
Further improvement of the present invention is: described alignment pin two ends are welded and fixed in the pilot hole that is connected to roller.
Further improvement of the present invention is: described two alignment pin are mutually vertical.
The present invention compared with prior art, has following positively effect:
1, roller is two-layer compound cylindrical shell, by the alloy layer of internal layer with cover outer field quartz-ceramics layer and be composited, make the present invention there is the features such as intensity is high, high temperature resistant, thermal expansion is little, chemical stability good, have stable high-temperature performance, indeformable, smooth surface is fine and smooth, wear resistance is good, solve preferably roll surface oxidation, furnace roller dross problem, can not produce loose and peeling phenomenon.
2, roller, roll shaft matching part are provided with two alignment pin that radially run through roller, roll shaft matching part, and an alignment pin wherein partly runs through another root alignment pin, like this, alignment pin difficult drop-off, roller is connected with roll shaft reliably; Alignment pin runs through roller, roll shaft matching part significantly improves roller, roll shaft strength of joint.
3, alignment pin two ends are welded and fixed in the pilot hole that is connected to roller, can further prevent that alignment pin from coming off, and further improve roller and roll shaft connection reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the local enlarged diagram of I part in Fig. 1.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
High temperature resistant, Wear-resistant double-layered composite furnace bottom roller shown in the drawings, comprises roller 1, is connected to the roll shaft 2 at roller 1 two ends; Roll shaft 2 inserts roller 1 end, forms and coordinates and be fixedly connected with; Roller 1 is two-layer compound cylindrical shell, by the alloy layer 1.1 of internal layer with cover outer field quartz-ceramics layer 1.2 and be composited.Like this, make the present invention there is the features such as intensity is high, high temperature resistant, thermal expansion is little, chemical stability good, have stable high-temperature performance, indeformable, smooth surface is fine and smooth, wear resistance is good, solve preferably roll surface oxidation, furnace roller dross problem, can not produce loose and peeling phenomenon.
The reliability and the strength of joint that in order to improve roller 1, are connected with roll shaft 2, the present invention is provided with two alignment pin 3 that radially run through roller 1, roll shaft 2 matching parts at roller 1, roll shaft 2 matching parts, and alignment pin 3 parts wherein run through another root alignment pin 3; In the present embodiment, alignment pin 3 two ends are welded and fixed in the pilot hole that is connected to roller 1, and two alignment pin 3 are mutually vertical, can further prevent that alignment pin 3 from coming off, and further improve roller 1 and roll shaft 2 connection reliability.
