Description
Technical field
The present invention relates to water-cooled nozzle field of material technology, particularly relate to the system of a kind of corrosion resisting steel for water-cooled nozzle
Preparation Method.
Background technology
The water cooling equipment of field of metallurgy is often used for the heat treatments such as quenching, makes gained alloy be strengthened, it requires water
Cool equipment has outstanding resistance to elevated temperatures.And the coolant in water-cooled often uses water or saline solution, easily make water cooling equipment
Surface oxidisation, therefore water cooling equipment also needs to have higher decay resistance.Alloy can be sent out with water cooling equipment in Cooling Process
Raw friction, therefore water cooling equipment also needs to have stronger anti-wear performance.
Water cooling equipment material often decay resistance of the prior art is not enough, needs a kind of new corrosion-resistant steel to be used for
Water cooling equipment.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes the system of a kind of corrosion resisting steel for water-cooled nozzle
Preparation Method, gained corrosion resisting steel have excellence decay resistance, and wear-resisting, resistance to elevated temperatures is good.
The preparation method of a kind of corrosion resisting steel for water-cooled nozzle that the present invention proposes, comprises the steps:
S1, raw material is warming up to molten condition obtaining liquid alloy, wherein the component of liquid alloy is by weight percentage
Including: C:0.1～0.25%, Cr:1.2～1.5%, Al:0.3～0.6%, Mg:1.2～1.6%, Zr:0.2～0.3%,
Ni:0.4～0.6%, Mn:1.2～1.3%, Mo:0.08～0.12%, V:0.1～0.13%, Co:0.03～0.06%, Ga:
0.02～0.05%, Ti:1.5～1.6%, Si:0.6～0.8%, remaining is Fe；Then cast obtains steel billet；
S2, heat treatment；
S3, boronising；
S4, cover conversion film.
Preferably, in S2, concretely comprising the following steps of heat treatment: slab heating-up is warming up to the programming rate of 5～8 DEG C/min
620～650 DEG C, be incubated 2～2.5h, be then warming up to 880～900 DEG C with the programming rate of 1～1.5 DEG C/min, insulation 45～
