Abstract
A roller for delivering steel billets features a tungsten carbide ring is adhered to its matrix at the position where it is easily worn by inorganic adhesive. Its manufacture or repair method includes such steps as processing by turning, washing, adhering, solidifying and welding stop rings. Its advantages are high resistance to abrasion and cracking, and long service life improved by 10-15 times.
Description
Technical field
The present invention relates to a kind of roller of transporting steel billet and manufacturing, restorative procedure, especially compound type conveying roller, claimed technical scheme belongs to the feedway technical field.
Background technology
The roller material of the transporting steel billet that existing steel rolling mill, steel plant continuous casting machine use is cast steel or cast iron, is integral structure, and whole hardness of roll body is identical, and this gives and uses the conveying roller use to bring many inconvenience.On the one hand, because roller use location difference, the worn-down degree is also inequality, the suitable hardness of roll body that uses should be differentiated, the hardness height is answered at position easy to wear, worn-down position hardness can not reduce, on the other hand, its integral structure roller hardness is low, easy to wear, wear no resistance, and the wearing and tearing that conveying roller is too early are when causing changing working expenditure, effort and spare part expend height, changing the more frequent field of employment of roller, this replacing has become influences the principal element that capacity rating improves, and therefore, is necessary whole conveying roller is improved.
Summary of the invention
Technical matters to be solved by this invention is, use the easy wear problems in position to propose a kind of technical scheme of transformation at roller, a kind of hardness height is provided, has roller than the compound type transporting steel billet of high-wearing feature, resistance to cleavage, this conveying roller can adopt different hardness of roll body according to operating needs, to overcome low shortcoming of conveying roller life-span in the prior art.For this reason, the present invention's method that also will provide a kind of manufacturing, repair this roller.
Technical scheme of the present invention is;
A kind of roller of transporting steel billet, it is characterized in that: between matrix and carbon tungsten roller ring, inorganic glue is arranged, matrix is cast steel, cast iron roller or worn out roller, carbon tungsten roller ring thickness is more than 5 millimeters or 5 millimeters, the tolerance clearance of roller matrix and carbon tungsten roller ring is 0.15-0.3mm, carbon tungsten roller ring Main Ingredients and Appearance WC70%, Co30%, carbon tungsten roller ring hardness: HRA84 is at the outside of carbon tungsten roller ring welding baffle ring.
The method of the roller of the transporting steel billet of a kind of manufacturing, reparation, bonding carbon tungsten roller ring on the matrix abration position, this method is as follows:
1) at roller matrix abration position diameter place's turning 10mm or more than the 10mm;
2) roller matrix and the roughness of roller surfaces place, carbon tungsten roller ring cooperation place are below 3, and the matrix external diameter is with 60 ° of sharp knives, and by depth of cut t=0.25mm, feed s=0.8mm, car go out the chaser flower;
3) gluing of surfaces is handled; Oxide on the roller matrix surface is cleaned down, with acetone difference washing roll adhesive portion external diameter, carbon tungsten roller ring (2) internal diameter and both sides;
4) bonding employing cupric oxide inorganic adhesive is bonding: 1 milliliter of phosphoric acid liquid adds 4-4.5 gram cupric oxide powder and joins glue, on copper coin, modulate and fully be in harmonious proportion with spatula, good glue is equal with rubber flap with being in harmonious proportion, repeatedly, promptly spread upon on two bonding planes uniformly, the roller matrix is stood up, then carbon tungsten roller ring is put to bonding location, removed cull;
5) solidify: placed 2-3 hour under the room temperature, send into baking oven and kept 1 hour for interior 50 ℃, be warming up to 80-100 ℃ of constant temperature again 2 hours.
6) with baffle ring (3) and roller matrix (1) weld together.
The roller of transporting steel billet of the present invention, roller have different hardness, and collars has higher resistance to abrasion, carbon tungsten roller ring hardness: HRA84, and especially red hardness is good when high temperature, long service life, and be difficult for wearing and tearing.Improve 10～15 times than cast steel, cast iron roller its comprehensive service life, and this roller is applicable to steel rolling mill, steel plant continuous casting machine transporting steel billet.
Description of drawings
Fig. 1 is the cutaway view of transporting steel billet roller of the present invention;
Fig. 2 is the cutaway view of carbon tungsten roller ring.
The specific embodiment:
As shown in Figure 1, select cast steel, cast iron roll subbase body 1, on abration position, use inorganic glue 4 bonding carbon tungsten roller rings 2, its Main Ingredients and Appearance WC70%, Co30%, carbon tungsten roller ring 2 thickness are more than 5 millimeters or 5 millimeters, the tolerance clearance of roller matrix and carbon tungsten roller ring is 0.15-0.3mm, and matrix 1 is cast steel, cast iron roller or worn out roller.For the bonding reparation of the roller of the transporting steel billet of carbon tungsten roller ring excessively, tear glue open as need, conveying roller can be immersed among the ammoniacal liquor, by knocking and the pressure effect, destroy glue-line.
Manufacturing of the present invention, the method for repairing this roller are as follows:
1) at roller matrix abration position diameter place's turning 10mm or more than the 10mm;
2) roller matrix and the roughness of roller surfaces place, carbon tungsten roller ring cooperation place are below 3, and the matrix external diameter is with 60 ° of sharp knives, and by depth of cut t=0.25mm, feed s=0.8mm, car go out the chaser flower;
3) gluing of surfaces is handled; Oxide on the roller matrix surface is cleaned down, with acetone difference washing roll adhesive portion external diameter, carbon tungsten roller ring (2) internal diameter and both sides;
4) bonding employing cupric oxide inorganic adhesive is bonding: 1 milliliter of phosphoric acid liquid adds 4-4.5 gram cupric oxide powder and joins glue, on copper coin, modulate and fully be in harmonious proportion with spatula, good glue is equal with rubber flap with being in harmonious proportion, repeatedly, promptly spread upon on two bonding planes uniformly, the roller matrix is stood up, then carbon tungsten roller ring is put to bonding location, removed cull;
5) solidify: placed 2-3 hour under the room temperature, send into baking oven and kept 1 hour for interior 50 ℃, be warming up to 80-100 ℃ of constant temperature again 2 hours;
6) with baffle ring (3) and roller matrix (1) weld together.
