Abstract
The present invention relates to high-silicon abrasion resistant cast steel. Carbon steel leftover or silicon steel leftover is adopted as raw materials; waste electrode graphite and other carburants are used to increase carbon; ferrosilicon alloy or SiC is used to increase silicon; molybdenum alloy is used for alloying; the ingredients of molten steel are controlled; a casting part is processed by heat. The abrasion resistant cast steel can work under an impact abrasion condition. Compared with high-manganese steel, the abrasion resistant cast steel has higher initial hardness and has still good abrasion resistance under abrasion conditions with a medium or small shock load. Compared with austenite-bainite nodular cast iron, the abrasion resistant cast steel has higher abrasion resistance, higher obdurability and wider applicable area. Compared with low-alloy steel, the abrasion resistant cast steel consumes less alloy elements, simplifies heat treatment, reduces cost and enhances abrasion resistance.
Description
The present invention relates to a kind of manufacture method of high-silicon abrasion resistant cast steel, belong to metallurgical technology field.
Existing casting wear-resistant steel mainly contains high mangaenese steel, carbon steel and low alloy steel, and casting graphitized steel three classes
[1-3]Wherein most widely used general in the high mangaenese steel of invention in 1882 with British Hadfield.The maximum characteristics of this steel are, under bigger shock load or contact stress effect, upper layer can produce work hardening rapidly, and are inner then still maintain good toughness.Therefore has good wear resistance.But in shock load or the not too high occasion of contact stress, this sclerosis effect that adds can not be given full play to, because the initial hardness of high mangaenese steel is very low, thereby wear resistance is very poor.
Carbon steel and low alloy steel mainly grows up as structured material rather than as wear resisting steel, and in order to improve wear resistance, adopting multi-element alloyed and strict thermal treatment is major measure, thereby cost is higher.
The casting graphitized steel is then substituted by spheroidal graphite cast iron, and in the wearing and tearing occasion that graphitized steel is suitable for, spheroidal graphite cast iron has better wear resistance.
Austria that developed recently gets up-shellfish magnesium iron (ADI) has good obdurability combination, is a kind of good high-abrasive material.But in the gouging abrasion occasion, the graphite among the ADI is inoperative.In addition, the carbon content basic fixed of matrix among the ADI is adjusted difficulty.
The objective of the invention is to study a kind of manufacture method of high-silicon abrasion resistant cast steel, it can be worked under the gouging abrasion condition, have higher initial hardness than high mangaenese steel, the wear resistance that under the abrasive conditions of middle or small shock load, still has; Have higher wear resistance and obdurability than Austria-shellfish magnesium iron, applicable surface is bigger; Lack than low alloy steel and to use alloying element, simplify thermal treatment, reduce cost, and improve wear resistance.
The composition prescription of the manufacture method of a kind of high-silicon abrasion resistant cast steel of the present invention's development is as follows: C Si Mn P S Mo0.6～1.2 1.8～3.0 0.4～0.6＜0.04＜0.04 0.2～0.5

2, with above-mentioned molten steel casting finished product workpiece;
3, the casting workpiece is heat-treated:
With the heating of≤100 ℃/speed at one hour rating, at 900 ± 20 ℃ of following austenitizings, soaking time 1～3 hour (every 2.5cm wall thickness 1 hour) is then at salt bath furnace (KON
350%+NaON
350%) quench in, quenching temperature is 280～400 ℃, 0.5～1.5 hour time.
At a large amount of medium and small ball grinding machine lining boards that use of China, excavator bucket teeth, grinder hammerhead, railway screen scarifier are taken off on the part such as chain and are used, and new steel grade should be realized improving work-ing life than existing material, the purpose that production cost reduces.
