Description
Technical field
One kind of the invention belongs to casting technology field without nickel magnesium kier preparation method.
Background technology
Because metal magnesium alloy refining requires that nickel content cannot be greater than 2/1000ths in composition, therefore, prior art is adopted more
The magnesium kier welded with the high-quality boiler plate without nickel.Although this magnesium kier can ensure that the nickel content of magnesium alloy does not surpass
Mark, but due to being welding product, it is short life, uneconomical.And because the melt viscosity without nickel boiler steel is larger, entrained air bubbles are difficult
With discharge, the weight of overall magnesium kier is typically at 2 tons or so, and cast melt flow is big, gas caused by casting process（Mainly
It is hydrogen）Steel plate or much higher, the current casting method of the bottom of a pan difficulty is fabricated separately in delivery ratio, and the yield rate of monoblock cast is only
Have 40%, do not reach industrial requirement much.And magnesium metal smelting relies primarily on outside heated by gas and internal magnesium chloride is molten
Agent is smelted, and inside and outside wall erosion of both media to kier is very big, is invaded quickly once there is stomata and is expanded disease rapidly
Stove, cause magnesium liquid to reveal, notably lead to great security incident.
The content of the invention
Overcome the deficiencies in the prior art of the present invention, technical problem to be solved are using whole without nickel steel metallic magnesium refining pot
The problem of body manufacture is difficult, and air bubble content is high, and qualification rate is low.
In order to solve the above technical problems, the technical solution adopted in the present invention is：It is a kind of without nickel magnesium kier preparation method,
Including with submarine gate set-up mode and method of smelting：
1）The magnesium kier shape for being shaped as just putting of die cavity, mold are provided with four cast gates, and two of which is arranged on die cavity top
Portion side, two are arranged on the height and position of cavity bottom 1/3, and four cast gates are in cross distribution outside die cavity during vertical view, and are pushed up
The cast gate in portion faces position setting；
2）A diameter of 0.8-0.9d of the cast gate of top two, a diameter of 1.1-1.2d of the cast gate of bottom two, wherein d are magnesium kier
Wall thickness；
3）Casting is required with the melting without nickel steel liquid：Casting molten steel adds quality of molten steel in 1000-1100 DEG C of temperature
0.3-0.4% rare earth ferrosilicon melting 20-30min, cools the temperature to 850-1000 DEG C and is cast afterwards.
The molten steel of setting of the invention by cross cast gate, the cast gate of top two and the cast gate of bottom two is in respective mobilization
Under, form deviation and liquidate and small rotation direction pressure, molten steel on the one hand can be promoted to be full of die cavity faster, avoid flowing due to long
Journey causes molten steel temperature to decline for a long time, influences casting quality；On the other hand molten steel internal pressure can be increased so that cast
Gas caused by inside has a small amount of extruding discharge in journey, during a small amount of gas is extruded discharge, is formed and is relatively beneficial to gas
" recessiveness " passage of discharge, created favorable conditions for discharge of the molten steel full of gas after die cavity.
Refined in addition, the temperature more than 1000 DEG C adds rare earth ferrosilicon, in addition to the effects such as refining, deoxidation, also
Molten steel viscosity can be effectively reduced, to reduce exhaust resistance.
The method of the present invention is used to use can be brought up to without nickel steel monoblock cast magnesium kier, yield rate by original 40%
80%, further, the running channel of the cast gate of bottom two tilts down the inclination angle from the horizontal by 3-5 °.
The invention has the advantages that, the present invention passes through cast gate quantity, distribution and size compared with prior art
Design so that after casting molten steel enters die cavity, can multiple feed quickly fill chamber, when the molten steel of the cast gate of bottom two converges and top
When the molten steel of two cast gates converges, it can slightly change molten steel flow direction, produce a small rotation direction power, molten steel Inner Constitution is squeezed
Pressure acts on, and promotes gas discharging caused by casting cycle.And by way of high temperature refinery and cooling casting, reduction is equally poured
The viscosity of molten steel at a temperature of note, reduce exhaust resistance.So as to which entirety reduces the air bubble content of monoblock cast magnesium kier, greatly
Improve manufacture qualification rate, reduce raw material, the energy, artificial, waste of time.The method of the present invention is by original 40% casting
Make qualification rate and brought up to 80% so that monoblock cast magnesium kier can be used in industrial production.The magnesium kier of monoblock cast is not
Weld seam be present, structural strength and service life improve a lot, and production efficiency also greatly improves with respect to welding production.
