おる。Detailed Description of the Invention (Industrial Application Field) The present invention relates to the improvement of rollers for continuous casting, and is widely used in the technical field of guiding and transferring red-hot high-temperature metal in continuous casting processes in steel plants. It is something that will be used.

Hot Charge Rolling: inserting a hot piece into a hot rolling heating furnace (Hot Charge Rolling)
With the spread of this method, the temperature of the slab tends to rise more and more, and as a result, the thermal load applied to continuous casting rollers becomes even greater, and the lifespan of the rollers is shortened.

料の使用が要求されている。In response to this, improvements in the material of the rollers are being considered, but recently it has become common to overlay heat-resistant metal on new rollers. Under such circumstances,
The quality of the overlay welding material greatly affects the life of the roller, and there is a demand for the use of welding materials that are highly corrosion resistant, wear resistant, and heat check resistant.

2-3 layers of 3% Cr welding material are welded onto the surface of the roller using a submerged automatic welding method using a strip electrode, ensuring a build-up thickness of 3-7m as an effective layer after machining. It has become

を製作しているのが現状である。In addition, submerged welding using wire electrodes and gas shield welding are also used in some cases, but from the standpoint of efficiency, submerged welding using band electrodes (hereinafter referred to as band welding) is generally preferred. Currently, rollers for continuous casting are manufactured using this method.

を行なっている。By the way, although the installed continuous casting rollers exhibit corrosion resistance, toughness, abrasion resistance, and heat resistance in harsh environments, they eventually wear out and cracks develop, making it necessary to replace them. However, it is removed from the equipment and repaired,
The repair rollers undergo a cycle in which the degraded surface is removed by machining, the diameter of the roller is restored by overlaying using the above-mentioned hand welding method, and then the rollers are put back into use.

い状況になりつつおる。However, as the casting equipment becomes hotter and the thermal load on the continuous protective roller increases, the durability of the roller decreases, and the situation is becoming unsatisfactory with domestic welding using 13Cr-based welding materials.

Although the application of a high abrasive material with a high Overlaying by the highly efficient band welding method, which is widely applied in welding, or the general submerged welding method is extremely difficult and not suitable for practical use.

とえ耐用度は向上したとしても、莫大なローラ製作費乃
至補修費となるためコスト面で実用的ではない。In general, when applying the conventional welding method described above using this high-grade high-alloy material, in order to secure an effective welding layer of 3 to 7 m, the machining allowance for work area processing must be considered. It is not practical in terms of cost to perform overlay welding to a thickness of 5.5 to 10# in advance, because even if the durability is improved, the cost for producing and repairing the roller is enormous.

．． Although overlay welding with a thickness of 5 to 3 # is possible, in this case,
Penetration occurs in the base material, and due to the inevitable dilution rate, 1
It is impossible to uniformly and stably secure the targeted high alloy component on the roller surface using just a layer.

適用は困難である。In addition, a thermal spraying method is used to thinly fuse a high-grade, high-alloy material to the roller surface.As a result of investigating the durability of rollers manufactured using this thermal spraying method, we found that the thermally sprayed material was Because it is not metallurgically bonded to the base material, but is a mechanical (physical) bond, under harsh usage conditions, a major defect occurs in which the sprayed layer peels off before the surface wears out. Application to continuous casting rollers is difficult.

提供することを目的とする。(Problems to be Solved by the Invention) The present invention has been researched and developed to address the above-mentioned problems, and is suitable for overlaying high-alloy materials on the surface of rollers for continuous casting. By adopting the previously unanticipated "powder plasma welding method," it is possible to form a high alloy layer on the roller surface extremely effectively and economically, even under harsh usage conditions. The object of the present invention is to provide an epoch-makingly useful continuous casting roller whose service life can be significantly improved.

を特徴としている。(Means for Solving the Problems) In order to achieve the above object, the continuous casting roller according to the present invention uses a powder plasma welding method to coat the body surface of the roller with Hastelloy alloy, Stellite alloy, Colmonoid, etc. Thickness 0.5 by overlaying high alloy powder such as alloy
It is characterized by forming an effective build-up layer of the high alloy as thin as ~2.0 m.

合金目標成分を確保できないからである。In the present invention, the thickness of the effective build-up layer of high alloy is 0.5~
The reason for specifying the range of 2.0 m is that if the distance is 0.5 m or less, even if the material is made of a high-alloy material with high durability, the layer will be too thin, and wear will begin and fine particles will gradually occur. This is because tortoiseshell cracks may easily progress to the base metal, making it impossible to improve durability.Also, even if the powder plasma welding method applied in the present invention has a small dilution ratio, The penetration depth is about 0.05m, and if it is less than 0.5#, it will not be possible to secure a dilution rate of about 5%.
This is because the target alloy components cannot be secured.

２．０＃を限度としているからである。In general, the effective build-up layer thickness is 2. If it is O# or more, it will of course contribute to improving the durability, but in terms of cost, it will be an expensive roller, and the criticality of cost effectiveness for manufacturing rolls for continuous casting in each steel mill will be ,
This is because the limit is 2.0#.

．． A roller for continuous casting was manufactured by removing 8 m as a cutting allowance and having effective build-up layers 6 of O0γ thickness at regular intervals. The manufacturing conditions are shown in the table below.
次に、既述した各従来法で最も母材ローラへの稀釈率が
小ざいバンド溶接法と上記本発明の実施例の場合を比較
した結果、本発明の場合の稀釈率が著しく小さかった。Next, as a result of comparing the band welding method, which has the smallest dilution rate to the base material roller among the conventional methods described above, and the case of the above embodiment of the present invention, the dilution rate in the case of the present invention was extremely small.

けで充分でおる。Therefore, when performing construction using the conventional band welding method, at least two layers of welding are required to ensure the target components on the roller surface, and it depends on the roughness of the welding surface and the amount of heat input during internal welding. It is necessary to allow for a machining allowance of around 2.5M due to dimensional changes due to the occurrence of distortion, but in the case of the present invention, the target component can be sufficiently secured on the roller surface with a thin overlay layer of single welding, and the machining allowance is also 0. It is sufficient to expect .8 to 1.0#.

使用回数をも増大できるものである。(Effects of the Invention) As detailed above, the continuous casting roller according to the present invention has a high gold overlay layer with excellent heat resistance, abrasion resistance, and corrosion resistance formed on the surface of the body. In addition to being able to withstand use under the harsh environmental conditions of continuous casting equipment, the roller uses a "powder plasma welding method" that was previously unanticipated for this type of roller when forming the elevated gold overlay layer. Since the amount of high alloy penetration into the base metal is small and the dilution rate can be kept small, the thin effective build-up layer with a thickness of 0.5 to 2.0 mm by only one layer welding can withstand harsh usage conditions. It has the advantage of ensuring sufficient target components on the roller surface, and even if high-grade materials are used, the cost is not as high as that of conventional rollers manufactured by overlaying 13Cr materials, and the durability is greatly increased. In addition to this, the amount of machining required for the built-up area during roller manufacturing and repair is naturally reduced, making it easier to manufacture and repair.
This can significantly contribute to reducing processing costs, and can also increase the number of times the roller can be reused.
