Embodiment Construction

[0010] See figure 1 , pour the alloy liquid into the granulation hopper 1, the alloy liquid drips from the rectangular outlet onto the rotary turntable 4, the temperature when dripping is 1000°C, the rotary turntable 4 is circular, and there is an involute groove on it 10. The groove width is 2mm-10mm, the groove depth is 0.5mm-2mm. The rotary turntable 4 is driven by the shaft 3 under the control of the speed-regulating motor 2 to rotate at a speed of 75 rpm to 200 rpm. It is granulated and formed through the involute groove 10 on it, and the size of the alloy particles is controlled by the speed of the rotary turntable 4, the size of the involute shallow groove, the height of the granulation hopper 1 and the size of the rectangular outlet of the granulation hopper. The alloy particles fall into the water quenching tank 6, and after quenching with cooling water, the product is obtained from the feeding port 8 to the finished product tank 9. The specific parameters are shown i...

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 [0001] The invention relates to a granulation method of a superalloy liquid, in particular to a granulation method of an alloy liquid which is difficult to be oxidized in air and chemically reacted in water quenching. technical background [0002] At present, the method of granulating superalloy liquid is generally to use heating method to heat the granulation hopper externally, so that the superalloy liquid is granulated through the granulation hopper, and then the metal particles are cooled by water jacket and air-cooled for water treatment. Quenching to obtain the product. Insulation of the granulation hopper requires energy consumption; insulation needs to increase the corresponding facilities, together with the water jacket, the total cost of the entire equipment will increase, resulting in an increase in production costs; the granulation speed in the granulation hopper is relatively slow . Contents of the invention [0003] The technical problem to ...
