It is equipped with a viscosity sensor and a mixing stirrer capable of negative pressure sucking tackifying agent in the tackifying chamber, as well as mixing stirrer capable of negative pressure sucking foaming agent in the foaming chamber. The present invention has convenient continuous regulation on melt viscosity and capacity of maintaining homogeneous melt viscosity, and may be used in preparing foam aluminum or foam aluminum alloy with certain foam distribution and different density via controlling the foaming agent or foaming gas sucking amount.
Description
Technical field
The invention belongs to metal products and make the field, particularly a kind of foam melt method prepares the foam device of foamed aluminium or foam aluminium alloy.
Background technology
Foamed aluminium is a kind of novel porous metal material.Characteristics such as lightweight that it had and high specific strength make it can be used as the potential structured material; Characteristics such as the sound absorption that is had, sound insulation, heat insulation, fire-retardant, damping, absorption striking energy and electromagnetic shielding make it can be used as functional materials.Thereby in each high-tech area and general industry fields such as Aeronautics and Astronautics, transportation, electronics, military project, chemical industry, environmental protection, the energy, machinery, biologies, the application of foamed aluminium has received concern more and more widely.The preparation method of foamed aluminium mainly contains seepage flow casting, powder metallurgic method and foam melt method etc. at present.The seepage flow casting generally is used for making fine-crystal spume aluminium alloy; Powder metallurgic method is because the production cost height is not suitable for producing the foamed aluminum materials that the general industry field is used.Foam melt method technology is simple, but there is following deficiency in existing direct foaming of melt mass method: (1) operation easier is big, uses TiH as described in US.pat.3743353
2When preparing foamed aluminium, stir foamed time and require to be controlled at 1～2min as whipping agent.(2) can only intermittent operation, as method improvement as described in the CN1320710A foreign patent, make the foamed aluminium operation easier greatly reduce, but this method belongs to gap operating; (3) controlled not at that time, there is certain thickness solid in the foam bottom, and foam skewness in the foams; Just because of these deficiencies, caused the production cost of foamed aluminium high, also limited the large-scale commercial applications application of foamed aluminium.(4) in order to solve the high authority of interval type foamed aluminium production cost, U.S. Pat .pat6984356B2 has described a kind of continuous preparation method of foamed aluminium, but this patent can not be measured as required melt is carried out online tackify, thereby does not also point out to measure online adjustment whipping agent to obtain having the foamed aluminium product of different porosities how as required.
Summary of the invention
The objective of the invention is to, provide a kind of and can measure the device that the melt of preparation foamed aluminium is carried out online tackify, online adjustment flux foaming amount as required, can obtain foamed aluminium or the foam aluminium alloy product that foam has good uniformity and has different densities by this device, and melt tackify in the foamed aluminium preparation process and simple, the easy control of tackifying fusant foaming operation.
The objective of the invention is to realize by following manner:
Foam device of the present invention is divided into tackify chamber and foaming chamber by dividing plate, and the pod apertures that melt in the tackify chamber can flow to foaming chamber is left in the bottom of dividing plate; But the tackify chamber is equipped with the mixing agitator of viscosity sensor and negative pressure suction tackifier; But described foaming chamber is equipped with the mixing agitator that negative pressure sucks whipping agent or foamed gas.
A safe relief hole is stayed in foaming chamber bottom, so that when unforeseen circumstances occurring, material can in time be discharged in the foaming furnace.
The passage of the suction tackifier of the indoor mixing agitator of described tackify is provided with the adjustment supply valve and adjusts the tackifier feed rate.
The suction whipping agent of described foaming chamber mixing agitator or the passage of foamed gas are provided with the adjustment supply valve and adjust soakage.
In the tackify of the present invention chamber, reach the mixing agitator that negative pressure sucks tackifier but be equipped with viscosity sensor; Thereby can reach the purpose of the indoor melt viscosity of online adjustment tackify; In described foaming chamber, but be equipped with the mixing agitator that negative pressure sucks whipping agent or foamed gas, thereby bubble rate in can online adjustment tackifying fusant can obtain having the foamed aluminium product of different porosities at last.
System of the present invention can make tackify and the foaming in the foamed aluminium continuous casting process adjust simple to operate, the easy control of this kind adjustment as required; Can obtain foamed aluminium or the foam aluminium alloy product that foam has good uniformity and has different densities by this system.

Embodiment
The specific embodiment of the present invention is: after will changing the foaming furnace of system of the present invention over to from the qualified aluminum or aluminum alloy melt that found smelting furnace (1), successively melt is implemented tackify and foaming, make the foaming melt enter follow-up continuous casting system at last and cast continuously.Below in conjunction with accompanying drawing the present invention is elaborated.
(1) described foaming furnace of the present invention (2) is divided into tackify chamber (21) and foaming chamber (22) by refractory materials dividing plate (200), and the pod apertures (201) that melt in the tackify chamber can flow to foaming chamber is left in the bottom of dividing plate; A safe relief hole (220) is stayed in foaming chamber (22) bottom, so that when unforeseen circumstances occurring, material can in time be discharged in the holding furnace.
(2) described tackify chamber (21) is equipped with viscosity sensor (210) but and the mixing agitator (211) of negative pressure suction tackifier.The viscosity of tackify chamber melt can be adjusted by the control requirement; When melt viscosity is higher than span of control, can introduces new melt from smelting furnace, or adjust supply valve (212) and turn the tackifier feed rate down; When melt viscosity is lower than span of control, can adjusts supply valve (212) and transfer big tackifier feed rate.The negative pressure of mixing agitator (211), the vacuum that is produced by the rotor rotation melt of high speed rotating wherein obtains; After tackifier were sucked melt by negative pressure, the high-shear in the agitator was changeed stator rapidly tackifier and melt thorough mixing, thereby had guaranteed the homogeneity of melt viscosity in the tackify chamber.
(3) described foaming chamber (22) but be equipped with the mixing agitator (221) that negative pressure sucks whipping agent or foamed gas, its negative pressure is rotated the vacuum that melt produced by agitator high speed rotating rotor and is obtained; Behind whipping agent or foamed gas negative pressure suction tackifying fusant, the high-shear in the agitator is changeed stator rapidly whipping agent or foamed gas and melt thorough mixing, thereby has guaranteed the homogeneity that bubble distributes in the foaming chamber.The soakage of whipping agent or foamed gas can be controlled by adjusting supply valve (222) in the foaming melt, thereby can obtain the foamed aluminium product of different porosities.
