Abstract
The invention discloses a manufacturing method of a metal valve. The metal valve has the beneficial effects of being resistant to corrosion, low in cost, high in thermal fatigue property and thermal stability and excellent in overall property through the material matching and the manufacturing process of metal materials. The metal valve has high surface oxidation resistance and is long in service life.
Description
Technical field
The present invention relates to a kind of manufacturing process of valve, particularly a kind of manufacture method of metal valve.
Background technology
Valve is generally made up of the valve internals of valve body and valve inner, can be divided into metal valve, Plastic valve and ceramic valve according to manufactured materials.
In production technology and technique, comparatively ripe in family expenses valve is metal valve, market comparatively common are stainless valve and copper valve, also cast iron valve is had in the product of low side a little, but there is considerable defect in existing metal valve, metal valve is in life-time service process, extremely easily there is the problems such as burn into gets rusty, plating exfoliation, can penetrate in domestic water gradually for the manufacture of heavy metals such as the lead in the alloy of metal valve, tin, domestic water is polluted, directly affects the healthy of people.
Summary of the invention
For solving the problem, the invention discloses a kind of manufacture method of metal valve.
In order to achieve the above object, the invention provides following technical scheme: a kind of manufacture method of metal valve, the material of described manufacture metal valve comprises as follows:
C1.2-2.6%Mn0.35-0.65%
Cr1.25-1.35%Mo0.80-0.90%
Si0.35-0.65Ni1.5-2.5%
All the other are Fe and inevitable impurity, and its manufacture method comprises the steps:
(1), by the material of above-mentioned each component carry out melting according to above-mentioned proportioning, smelting temperature is 1200-1330 DEG C;
(2), by the material after above-mentioned melting send in mould and build, placing temperature is 1150-1220 DEG C;
(3), mould is cooled 18-20 hour as in sand;
(4), by the metal valve base substrate of building carry out anneal, annealing temperature is 880-920 DEG C;
(5), again metal die base substrate is carried out quench treatment, quenching temperature is 950-1030 DEG C;
(6) the metal die base substrate after, step 5 being processed again carries out temper between 700-750 DEG C;
(7), by the metal die base substrate after tempered process carry out insulation 2-4 hour, be cooled to 200-250 DEG C to come out of the stove;
(8), emery wheel is adopted to refine metal die base substrate, surface working is smooth.
Beneficial effect:
Metal valve of the present invention, by above-mentioned material mixture ratio and manufacturing process, has corrosion resistance nature, with low cost, thermal fatigue property, thermostability are high and the feature of high comprehensive performance.And it has higher surface oxidation-resistant ability, long service life.
