れたセラミック溶射ロールに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ceramic spray roll that is used in a cold rolling process and has excellent pick amp resistance.

、平均寿命は４ケ月イー：Ｉ負である。Conventionally, Sendzimir mills' Teflex rolls for stainless steel have been used with Cr plating on the surface of the metal roll, but due to the relationship between the adhesive strength and surface hardness between the coating and -IJJ material, plating peeling and roll scratches may occur. , wear occurs, and the roll life varies from one week to six months, with an average life of four months.

ンク溶身４０−ルを適用することはできなかった。Recent technology has advanced into the field of ceramic coating or Cr coating for the purpose of improving bond strength and wear resistance t1. However, in the Kanba process, when ceramic 910-ru is applied instead of Cr metal 7-kilo, the problem of pink amplifier occurs. In particular, it was not possible to apply Ceraminku Solu 40-L to Teflextrol of Senshimia Mill for stainless steel because it did not affect the quality of the pink amplifier or strip.

である。The reason is as follows. The surface of the roll needs to have a roughness of +a to prevent the strip from slipping. This roughness formation process is similar to that in the case of coating, in which the roughness of the roll surface is adjusted by shot fracturing, and then the final plating film is formed.
In case 4, after forming the sprayed coating, the roughness is adjusted using Nyontoplast. Therefore, in the latter case, the tips of the protrusions that form the surface roughness become sharp, and fine metals and foreign matter are deposited on the slip, resulting in a so-called pick amplifier.

The purpose of the above machine is to reduce the life span of rolls for the rolling process by 1Δ, with the advantages of high wear resistance and adhesive strength. In order to eliminate the pink amplifier that occurs on the surface, the aim is to limit the 711 degree range and mold the tip of the microprotrusion into a round shape to improve the resistance to pimples, quakes, and pimples. do.

、冷延プロセス川のロールとしてはピンクア。To explain the production of the ceramic thermal spray roll according to the present invention, the ceramic is coated on the surface of the metal roll using the dregs explosion thermal spraying method or the plasma blasting process by 47 people. After forming one film of ri, the roughness of the roll surface is adjusted after polishing and blasting. Table II at this stage
The '11 profile has a protrusion or sharpness as shown in the Th++ s diagram, and is pink for a cold rolled process roll.
