Abstract
The present invention relates to a high-hardness, weldable and wearproof casting alloy which belongs to a ferrousalloy. The present invention has the ingredients (by weight percentage) of 0.1 to 0.6% of C, 2 to 5% of Si, 0 to 0.7% of Mn, at most 0.05% of P, at most 0.05% of S, 2 to 6 % of Ni, 0 to 0.06% of Al, 0 to 2% of Cu, 0 to 0.5 % of MO, 7 to 13% of Cr, 1 to 14% of B and Fe as the rest; the material has the advantages of high wearproof property, good weldability, simple smelting process and good casting property, and is suitable for casting wearing terrain type bodies of various wearing 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, it is frequent to change, production efficiency 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 the complex process end can be popularized.
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 chemical ingredients of alloy provided by the invention is as follows: (calculating by weight per-cent): carbon (C) accounts for 0.1-0.6%; Element silicon (Si) accounts for 2-5%; Manganese element (Mn) accounts for 0-0.7%; Phosphoric (P)≤0.05%; Element sulphur (S)≤0.05%; Nickel element (Ni) accounts for 2-6%; Molybdenum element (Mo) accounts for 0-0.5%; Chromium element (Cr) accounts for 7-13%; Copper (Cu) accounts for 0-1%; Boron (B) accounts for 1-4%; Aluminium element (Al) accounts for 0-0.6%; All the other compositions are ferro element (Fe).
The chemical ingredients of the alloy of preferentially selecting for use is: (calculating by weight per-cent): carbon (C) accounts for 0.25%; Element silicon (Si) accounts for 4.2%; Manganese element (Mn) accounts for 0.3%; Nickel element (Ni) accounts for 4%; Molybdenum element (Mo) accounts for 0.3%; Chromium element (Cr) accounts for 11%; Copper (Cu) accounts for 0.8%; Boron (B) accounts for 2. 3%; Aluminium element (Al) accounts for 0.3%; All the other compositions are ferro element (Fe).
The cost of this high hardness weldable wearproof alloy is lower by 1/3 than C-Cr-B alloy, and hardness of cast form HRC＞55 can be welded with cast iron, carbon steel, low alloy steel, high mangaenese steel, satisfy job requirements.
Embodiment:
The present invention is with common molybdenum-iron, high, medium carbon ferrochrome, and ferrosilicon, red copper (electrolytic copper), electrolytic nickel and A carbon steel waste material are raw material.
The chemical ingredients of alloy is: (calculating by weight per-cent):
Carbon (C) accounts for 0.25%; Element silicon (Si) accounts for 4.2%; Manganese element (Mn) accounts for 0.3%;
Nickel element (Ni) accounts for 4%; Molybdenum element (Mo) accounts for 0.3%; Chromium element (Cr) accounts for 11%;
Copper (Cu) accounts for 0.8%: boron (B) accounts for 2.3%; Aluminium element (Al) accounts for 0.3%;
All the other compositions are ferro element (Fe) and other impurity element.By this prescription melting in induction furnace, require to adopt sand mo(u)ld, disappearance mould, die and precision casting according to difference then.The various type bodies in casting back do not need thermal treatment.Tie the conventional weldprocedure of 422 welding rods and carbon steel and high mangaenese steel, cast iron welds and reaches service requirements.
