Description
Technical field
The present invention relates to boat technique field, specially a kind of sintered hard alloy boat contact material.
Background technique
The alloy boat of W-Mo powder reduction both at home and abroad generallys use pure nickel, the casting of nickel chromium triangle system high temperature alloy or stainless steel at present
Expect welding manufacture, has many advantages, such as that elevated temperature strength is good, deforms small, low production cost, processed compared with other boat materials and boat
Technique has apparent advantage, by the favor of CEMENTED CARBIDE PRODUCTION industry.But all there is product and hold in cast superalloy boat
The difference defect such as the temperature received lower (about 900 DEG C or so), the short, boat easy to stick of service life, such as uses the pure nickel boat of casting technique
Ware, although performance is more stable under its high temperature, in use process, nickel boat surface is easily Nian Jie with tungsten powder material, i.e., in boat
Ware surface will form one layer be firmly combined with matrix, oxidation film not easily to fall off, cause in the preparation process of tungsten powder material
Waste is big, meanwhile, pure nickel boat elevated temperature strength is low, can occur in the case where pushing away boat power and thermal stress effect severely deformed, influences boat
Use.Nickel chromium triangle system high temperature alloy boat although elevated temperature strength and non-deformability with higher, but in reducing atmosphere
Work, Yi Fasheng spot corrosion, serious person may occur in which local perforations.Equally, also existed using the boat of heat-resistance stainless steel welding manufacture
Similar problem, and oxidation and spot corrosion are more serious, elevated temperature strength is also below nichrome.
Material selected by traditional boat contact material is more single, lower (about so as to cause the bearing temperature of traditional boat
It is 900 DEG C), cause traditional boat to be easy the situation of peeling in use, while being easy to happen the situation of viscous boat, in high temperature
Under state, product is also easy to be corroded by impurity, and then causes the qualification rate of product low, largely wastes resources of production, Jin Erti
High production cost.
Summary of the invention
The purpose of the present invention is to provide a kind of sintered hard alloy boat contact materials, to solve above-mentioned background technique
The low problem of traditional boat contact material bearing temperature of middle proposition.

Preferably, P≤0.04%, S≤0.04%, N≤0.04%, O≤0.04% in the inevitable impurity.
Preferably, boat contact material manufacture process the following steps are included:
(1) it suppresses cere: choosing medium temperature and cast wax material, then wax material is pressed into using pressure and is formed, to its cooling, solidification
After take out；
(2) it makes mold: bonding agent being mixed with ingredient, refractory material is made, is then applied to above-mentioned cere surface, instead
Overcoating is smeared 7-9 times, and the fireproof die of a thickness 7-9mm is made；
(3) dewax: temperature is 150-210 degrees Celsius in control autoclave, is protected and is dewaxed using vapor injection；
(4) roasting molding: the mold after dewaxing is placed in high-temperature heater, using continuous roasting, is gradually heated
Mode is heated to 920-1050 degrees Celsius and is roasted, and roasts 7-9 hours；
(5) melting: metallic nickel being added into smelting furnace, and metallic iron, crome metal, metal tantalum and metal is added after its fusing
Tungsten until fusing, then into melt be added rare earth silicon carry out pre-deoxidation processing, add graphite, adjust melt chemistry at
Point, final deoxidizing is carried out to melt using Titanium and metallic aluminium, it is Celsius to be adjusted to 1550-1700 for temperature after melting liquid deoxidizing processing
Degree；
(6) moulding by casting: above-mentioned melt being poured into the mold that roasting is come out of the stove, and the temperature of die casting is 920-1100
Degree Celsius, mold is placed on sand table after coming out of the stove and closely puts.
Preferably, the fireproof die includes mold shell surface and mold reinforcing layer.
Preferably, the mold shell surface is used as bonding agent using silica solution, the ingredient of the mold shell surface use zircon sand or
Zirconium powder.
Preferably, the mold mold reinforcing layer using silica solution as bonding agent, adopt by the ingredient of the mold reinforcing layer
With Mo Laisha or mullite powder.
Compared with prior art, beneficial effects of the present invention are as follows:
It can be improved using Ni-Fe-Cr-W system alloy by the method for Al element in boat contact material in the present invention
The intensity of boat reduces the pollution of impurity, by the addition of Ti element, can be improved the high-temperature corrosion-resistance performance of boat, in turn
The bearing temperature for increasing boat is greatly increased, to achieve the effect that non-scale and not glue boat.
