Abstract
The invention relates to a novel low-MnCrNi cast steel material and a preparation method thereof. In the traditional engineering construction, concrete pump trucks are commonly used, and because the casting technology has defects and the produced pipe elbow for a pump truck has poor abrasion resistance and tensile strength, the quality and service life of a product are seriously influenced. The invention aims at providing a pipe elbow material which has the advantages of compressive resistance, strong abrasion resistance, low production cost and long service life. The pipe elbow material is formed by casting iron utilized as a main raw material as well as components containing carbon, silicon, magnesium, phosphor, sulfur, chromium, nickel, molybdenum and cobalt, and has the advantages of good compressive resistance and abrasion resistance, low production cost, less investment, fast response and good effect.
Description
Technical field:
The invention belongs to new metallic substance technical field, be specifically related to a kind of low manganese chromium nickel cast steel novel material and method for formulating.
Background technology:
As everyone knows, along with the develop rapidly of modernization construction, must rely on popularizing and using of modern engineering equipment, the concrete pump truck that in engineering construction, adopts, then be to improve construction quality, accelerate speed of application, the important mechanical implement of increasing work efficiency; And existing home-made pipe elbow all is to adopt conventional production methods, causes carbonization inhomogeneous, and closeization degree is low, and sintering character is poor, and therefore the strong head of the product tension of producing is extremely low with wear resisting property, causes the turnover rate height, has had a strong impact on concrete transport efficiency.Though pipe fitting, the elbow wear resisting property of part import at present are good, can cost an arm and a leg the high benefit that influences of cost.
Summary of the invention
The objective of the invention is defective according to above-mentioned technology, and provide a kind of low manganese chromium nickel cast steel novel material and method for formulating, it is poor that it can solve the existing pipe elbow wear resisting property of producing effectively, work-ing life is short, ineffective defective, and produce a kind of compressive resistance, wear resisting property is strong, production cost is low, the new high-abrasive material of long service life.
The present invention is achieved in that this product is is main raw material with iron, and is equipped with carbon, silicon, manganese, phosphorus, sulphur, chromium, nickel, molybdenum, the casting of cobalt composition formulated in combination and forms, and its method for formulating is as follows:
A prescription: weight precentagewise (%)
B technology
Above-mentioned materials is assorted by weight percentage, placed foundry furnace to melt, again with the molten metal material running castings, take out foundry goods then, foundry goods is taken out in the resolidification cooling of former back, and dead head and burr are removed in cleaning, thermal treatment (normalizing+tempering), check warehouse-in.
Beneficial effect of the present invention: this product is for engineering construction provides that a kind of wear resisting property is superpower, tensile strength good, long service life, abrasion resistance material that production cost is low, profitable.
Embodiment:
The best of a kind of low manganese chromium nickel cast steel novel material of the present invention and method for formulating is implemented prescription: chemical ingredients per-cent (%) by weight
Claims (2)
1. one kind low manganese chromium nickel cast steel novel material and method for formulating, this product are to be main raw material with iron, and are equipped with compositions combinations such as carbon, silicon, manganese, phosphorus, sulphur, chromium, nickel, molybdenum, cobalt, and the preparation casting forms, and it is characterized in that method for formulating is as follows:
A prescription: chemical by weight per-cent (%)
B technology:
Above-mentioned materials is assorted by weight percentage, placed foundry furnace to melt, again with the molten metal material running castings, take out foundry goods then, foundry goods is taken out in the resolidification cooling of former back, and dead head and burr are removed in cleaning, thermal treatment (normalizing ten tempering), check warehouse-in.
2. a kind of low manganese chromium nickel cast steel novel material according to claim 1 and method for formulating, the most accurate enforcement prescription of its this product of feature is as follows: chemical by weight per-cent (%)
