Abstract
The utility model relates to a hard coating of a roller for continuous casting machines, wherein a roller of a continuous casting machine is provided with a tungsten carbide medicated core chromium series stainless steel materials in a resurfacing welding mode. The utility model can prevent a delivery roller from being cut through effectively during the flame cutting of a casting blank and make the performance of the roller stable. The utility model has the advantages of no crack, high temperature resistance, corrosion resistance, abrasion resistance, shock resistance and non-stick casting blank, and the service life of the utility model are more than 18 months.
Description
One. technical field
The utility model belongs to straightening roller and the conveying roller hard cladding that conticaster is used.
Two. technical background
Strand is being carried out in drawing, alignment and the course of conveying, and mechanical load is big especially, causes the strand translational speed very slow, in carrying the strand process, because of cutting machine does not cut off strand fully, and need people manually to cut off, owing to grasp bad dynamics with flame cutter, often make flame cutter that conveying roller is cut perforation, thereby roller is scrapped, caused waste, as carrying out surface treatment with spraying or surfacing pair roller, its cover layer easily comes off, and adhesion is not strong; In addition, the straightening roll surface contacts with strand for a long time, and it is fast that its temperature is risen, the temperature height, again through cool water shower, repeated multiple times just usually chaps roll surface, is subjected to the corrosion of high-temperature oxydation and cooling water, roll surface very easily peels off, cause unevenly, have a strong impact on cc billet surface quality, body of roll mechanical strength also reduces greatly; Generally have only about 3 months service life.
Three. summary of the invention
The purpose of this utility model, to provide exactly a kind of with carbide alloy conticaster with roller on built-up welding one deck hard cladding.Conticaster with roller on built-up welding hard cladding is arranged, the conticaster roller is No. 45 steel or common alloy material, method with built-up welding is welded in carbide reactor on the roller, form hard cladding, hard cladding adopts tungsten carbide medicine core chrome stainless steel, and it is thick that built-up welding thickness can be 1～10mm, and it can use the required coverage of technology controlling and process, make coating and matrix itself have enough bond strengths, to satisfy needed intensity and performance in the production process.The utility model is owing to adopt carbide alloy to cover conticaster with on the roller, can prevent from effectively when the hand cut strand conveying roller cut and wear, the stable performance of straightening roller is not chapped, high temperature resistant, corrosion-resistant, wear-resistant, shock resistance, anti-flame cutting, not sticking strand, service life can be more than 18 months, and economic benefit is very remarkable.
Four. description of drawings
Be conticaster roller and hard cladding structural representation among the figure.
As shown in FIG., conticaster adopts No. 45 steel with roller 1 and hard cladding 2, conticaster with roller, and the Delstrain 414N-O alloy material that hard cladding adopts Shanghai Si Taili company to produce covers 3mm on the roller with the method for built-up welding with it.
Claims (2)
1. conticaster is made up of roller and hard cladding with the hard cladding of roller, it is characterized in that: going up built-up welding at conticaster with roller (1) has hard cladding (2).
2. the conticaster according to claim 1 hard cladding of roller, it is characterized in that: hard cladding (2) is a tungsten carbide medicine core chrome stainless steel material.
