Abstract

A kind of non-adhibit steel material that used in reeling machine which consists of the following elements: 0.30-0.70% C, Cr,0.50-1.0% Si, 1.0-1.50% Mn, 0.03% P,0.02% S, 1.0-2.0% Mo, 0.2-0.4% V, 5.0-8.0% W, 0.02-0.05% Co, and Fe the rest. The adhibit phenomena was eliminated by reducing the Cr content in hard facing deposit in roller surface greatly(5.0-8.0%),increasing Mo,V,W,Co content to improve the intensity, rigidity and abradability so that the non-periodicity impress in band iron was reduced by 70%.

Description

technical field [0001] The invention relates to a roll surface material, in particular to a non-stick steel material for the surface of a coiling auxiliary roll of a coiler. Background technique [0002] In the prior art, the surface of the coiling auxiliary roller of the hot rolling coiler is mostly made of martensitic stainless steel welding wire (the surface of some of the auxiliary coiling roller of the hot rolling coiler is also made of spray welding, but this type of roller surface is not suitable for coiling high-strength The specific composition of the martensitic stainless steel wire material used on the surface of the coiling roll is shown in Table 1 below: [0003] Table 1 Martensitic stainless steel welding wire material composition list (weight %) for the surface of the winding roll [0004] C Cr mn Ni Si other Fe Hardness 0.5～0.6 10～14 1.5～1.8 1.0～1.2 0.18～0.2 ...
