Abstract
The present invention relates to a high-hardness weldable wear-resistant casting alloy. Its composition is composed of (wt%) C 0.1-0.6, Si 2-5, Mn 0-0.7, P less than or equal to 0.05, S less than or equal to 0.05, Ni 2-6, Al 0-0.06, Cu 0-2, Mo 0-0.5, Cr 7-13, B 1-4, and the rest is Fe. This material not only possesses higher wear-resisting property, but also possesses good weldability, its smelting process is simple, castability is good, so that it is applicable for casting wearing parts of various vulnerable parts.
Description
The invention belongs to ferrous alloy, be applicable to the cast moulding body of the abrading section of industry consumable accessorys such as manufacturing, mine, building materials, coal, electric power.Utilize the vulnerable part of alloy of the present invention and process program combination, can improve 3-5 times of work-ing life.
Tup, strike plate, pick tooth, the pick of the crusher of industries such as mine, building materials, coal, electric power all are consumable accessorys.At present the consumable accessory great majority are all made with carbon steel, low alloy steel and high mangaenese steel, and these consumable accessorys are mostly used bearing under the operating mode of low, moderate ballistic strong abrasive wear, and the part abrasion are big, change frequent, productivity is low, steel quantity consumption is big.The only a few factories and miness adopt built-up welding vulnerable part surface to improve application life, because cost is high and complex process fails to popularize.
The objective of the invention is to make and a kind ofly have: as cast condition high hardness weldable wearproof, price be low, have build-up wear-resistant concurrently, good castability, and can utilize covered arc welding with enclose, point, plug welding connect form, the high hardness wear-resisting type body after AC and DC is tied 422 welding rod common process and will be cast is welded on being ground on the position of consumable accessory.

The cost of this high hardness weldable wearproof alloy is lower by 1/3 than C-Cr-B alloy, and hardness of cast form HRC55 can satisfy the effect requirement with cast iron, carbon steel, low alloy steel, high mangaenese steel welding.
Embodiment:
The present invention is with common molybdenum-iron, height, medium carbon ferrochrome, ferrosilicon, ferro-boron, red copper (electrolytic copper), electrolytic nickel and A
