Abstract
The invention discloses a steel material for a corrosion-resistant mould. The steel material is characterized by comprising the following components by weight percent: 0.162%-0.219% of C, 0.45%-0.52% of Ni, 0.16%-0.34% of Cu, 0.16%-0.28% of P, 0.23%-0.29% of S, 0.453%-0.562% of Ti, 0.23%-0.25% of phosphorus cerium lanthanum alloy, 0.03%-0.05% of V and the balance of Fe and trace impurities. The steel material has very good corrosion resistance on substances such as acid and alkali and is compact in texture, and the maintenance cost of the mould made of the steel material can be greatly reduced.
Description
Technical field
The present invention relates to field of iron and steel smelting, be specifically related to a kind of preparation technology of die steel material.
Background technology
The methods such as mould refers in industrial production in order to injection moulding, blowing, extrudes, die casting or forging forming, smelting, punching press, stretching obtain various moulds and the instrument of desired product, are used for the instrument of formed article, are normally formed by metal manufacture.The mould-type that factory is used is at present mainly cast molding mould, extrusion moulding and die-casting forming die.These moulds inevitably and between formed article come in contact in process of production, often have soda acid on formed article, inevitably there will be the problems such as corrosion, will cause like this die face to occur spot, uneven, often need more mold exchange, increase production cost.
Summary of the invention
The problem existing for prior art, the object of the present invention is to provide a kind of preparation technology of corrosion-resistant die steel material, the wear-resistant type die steel material that described composition steel are manufactured, the materials such as soda acid are had to very strong erosion resistance, the densification of steel quality, the mould of being suppressed by steel of the present invention can greatly reduce maintenance costs.
For achieving the above object, the technical scheme that the present invention takes is: a kind of corrosion-resistant die steel material, it is characterized in that, and described steel are taking its raw material part composition of massfraction as (%): C 0.162～0.219, Ni 0.45～0.52, Cu 0.16～0.34, P 0.16～0.28, S 0.23～0.29, Ti 0.453～0.562, phosphorus cerium mischmetal 0.23～0.25, V 0.03～0.05, all the other are Fe and trace impurity;
Described corrosion-resistant die steel material, it is 95% nano-carbon powder that the C adding adopts content;
Described corrosion-resistant die steel material, the Ni adding, Cu adopt Ni25Cu11 alloy, and Ti adopts Ti16Fe84 titanium alloy;
Described corrosion-resistant die steel material, the phosphorus cerium mischmetal adding is containing cerous oxide 25-30%, lanthanum sesquioxide 20-30%, thorium dioxide 5-12%;
Described corrosion-resistant die steel material, production process comprises the steps: to get the raw materials ready, and melting drops into auxiliary material, and casting is quenched, and specifically comprises the steps:
(1) get the raw materials ready: select pig pickling to remove impurity, select Ni25Cu11 alloy, the Ti16Fe84 titanium alloy of respective amount nano-carbon powder, respective amount simultaneously;
(2) melting: the pig after pickling is put into smelting furnace, be heated to 2000 DEG C of fusings;
(3) drop into auxiliary material: in the pig iron liquid after fusing, drop into Ni25Cu11 alloy, the Ti16Fe84 titanium alloy of respective amount nano-carbon powder, respective amount;
(4) casting: evenly, iron liquid is poured into cast molding in the mould of different shaped shape;
(5) quench: rapid quenching after cast molding, the compactness of raising steel is carried out throwing flat processing in surface until mold cools down to normal temperature, smears to support and uses automotive engine oil.
Corrosion-resistant die steel material of the present invention, has very strong erosion resistance to materials such as soda acids, the densification of steel quality, and the mould of being suppressed by steel of the present invention can greatly reduce maintenance costs.
