Abstract
This invention relates to a type of dh nodular cast iron abrasion resistance jaw. Alloy element is mainly added with type of compound mineral material power at first. Alloy materials includes (%) CaC2 (carbide)/Ca 0.03-0.05,MgO(magnesia power)/Mg 0.01-0.02,Al0.40-0.50,[co(NH2)2]( urea)/N0.20-0.25, N2B4O7(boron sand)/B0.60-0.80,Al2O3(emery sand)/Al2O30.02- 0.03,TiO2(rutile)Ti0.03-0.04,ZrO2/Zr0.02-0.03, V2O5/V0.06-0.08,Nb2O5 .Ta2O5(tantalite power)/Nb .Ta 0.02-0.03,Cr2O3(chromite power)/Cr0.50-0.80,MoS2(molybdenite power)/Mo0.02-0.03,MnO2(pyrolusite power)/Mn0.20-0.30,REO(rare earth power)/RE0.50-0.60. After pre-heat, adding above alloy materials to hot metal which contains nodular cast iron in the ordinary smelting furnace, and using ordinary sand mold or metal mold to pour shaping. High antifriction property, low breakage rate, good impelling strength, and high corrosion stability.
Description
The present invention relates to a kind of cast iron alloy wear resistant jaw plate.
Existing ball mill white cast iron anti-wear blade of a sword plate, though use properties is preferably arranged, but it is expensive that appointed condition height, complex manufacturing, alloy material are worth, alloy material as the white cast iron anti-wear blade of a sword plate of chromium 15% molybdenum 30% and chromium 18% manganese 2.8% is to join steel scrap melting in basic electric arc furnace with " ferrochrome ", " ferro-molybdenum ", " manganeseirom " with the GB pig iron, also will carry out oxidation, reduction and adjustment Chemical Composition, particularly chromium 18% manganese 2.8% also needs rotten processing repeatedly after melting.Casting mold needs special sand, sand mold or heating resisting metal type, and chromium content height, special molybdenum is the alloy material of rare costliness.
Purpose of the present invention: be exactly to utilize common smelting furnace, simple technology, cheap alloy material to add in the iron liquid of common spheroidal graphite composition, can be cast as the higher ductile iron antiwear blade of a sword plate of resistance to abrasion.
The present invention is by (%) CaC

Add in the casting ladle after the above alloy material preheating and pour at common smelting furnace (tilting cupola, medium-frequency induction furnace), the molten iron of the common spheroidal graphite composition of melting gets final product casting.
Technical characterictic: the alloy material of adding is with the smart powder of the mineral substance of chemical combination attitude substantially, and is nitride forming element.
Through manufacturing experimently its performance: HRC (Rockwell hardness number) 55～60, J/cm
27～8 (notched bar impact strengths), rupture rate＜1%, corrosion resistance height, particularly wet mill use.
