Abstract
The present invention relates to a kind of pelletizing high temperature alloy liquid. The production process includes pelletizing in rotary table as one a rotation part and water quenching the pellets. The production process is simple and has alloy temperature of 200-2000 deg.c, stable alloy pellet size of 0.5-5 mm, low investment in equipment, low power consumption and low cost.
Description
Technical field
The present invention relates to a kind of high temperature alloy liquid granulating method, particularly in air, be difficult for oxidation, when shrend, be difficult for the granulating method of the alloy liquid of chemical reaction.
Technical background
At present; the method of high temperature alloy liquid granulation generally is to utilize heating means that the granulation hopper is carried out outer insulation; make high temperature alloy liquid carry out granulation, then metallic particles is carried out shrend after by water leg cooling and air cold shock and obtain product by the granulation hopper.Being incubated for the granulation hopper needs consumes energy; Insulation needs to increase corresponding facility, with water leg the total cost of entire equipment is increased, and causes production cost to rise; Granulation speed in the granulation hopper is relatively also slower.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly carries out the method for granulation to high temperature alloy liquid, and it can improve granulation speed, and can cut down the consumption of energy and production cost.
Solving the scheme that technical problem of the present invention adopts is: alloy liquid is dripped granulation to the rotary turntable, and turntable places watch-quench tank, and alloying pellet drops down onto watch-quench tank again, directly cool off product.
Technical scheme of the present invention also comprises following proposal: the temperature that liquid high temperature alloy oozes from the granulation hopper outlet is 200 ℃～2000 ℃, leave involute formula shallow slot on the rotary turntable, groove width 2mm～10mm, groove depth 0.5mm～2mm, its rotary speed is 50 rev/mins～300 rev/mins; Alloy liquid is to drip to rotary turntable by the rectangle outlet of middle hopper, and the bore of outlet is wide to be 100 * 4mm～100 * 10mm.
Because alloy granulation of the present invention is to carry out on rotating movement parts, can simplify the structure of original granulation hopper greatly, does not need hopper is incubated in granulation, can save energy, and granulation is speeded up; In the shrend process,, do not need conventional water leg and cold shock air to cool off, so production cost is lower because alloying pellet directly falls into watch-quench tank.
Description of drawings
Fig. 1 is a facility schematic diagram of the present invention;
Fig. 2 is the turntable schematic diagram of facility of the present invention;
Each label is represented successively among the figure: granulation hopper 1, buncher 2, axle 3, turntable 4, cooling water pipe 5, watch-quench tank 6, water inlet 7, feed opening 8, pan tank 9, involute groove 10.
The specific embodiment
See Fig. 1; pour alloy liquid into granulation hopper 1; alloy liquid drops on the rotary turntable 4 from the rectangle outlet; temperature during drippage is 1000 ℃; rotary turntable 4 is circular; have involute groove 10 on it; groove width 2mm～10mm; groove depth 0.5mm～2mm; rotary turntable 4 drives with 75 rev/mins～200 rev/mins speed rotations through axle 3 under the control of buncher 2; alloy is being shaped by involute groove 10 granulations on it on the rotary turntable 4; the size of alloying pellet is by the speed of rotary turntable 4; the size of involute shallow slot; the size control of the height of granulation hopper 1 and the outlet of granulation hopper rectangle; alloying pellet falls into watch-quench tank 6; obtain product by feed opening 8 to pan tank 9 after the cooling water shrend, concrete parameter is face table 1 and table 2 as follows.
