Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the present invention will be described in further detail.
As shown in Figure 1 and 2, a kind of shot-peening steel ball production equipment, comprise the tank 1 that cooling water is housed, hopper 2 is provided with directly over described tank 1 centre, be positioned at immediately below hopper 2 in the middle of described tank 1 and be provided with sub-material rotating disk 3, offer capaciting material groove 4 in the middle part of described sub-material rotating disk 3, sub-material rotating disk 3 perimembranous is evenly equipped with and is disposed radially and the discharging opening 5 be connected with capaciting material groove 4.Molten steel in hopper 2 falls into the capaciting material groove 4 of sub-material rotating disk 3, when sub-material rotating disk 3 rotates, radially scatters under centrifugal action from discharging opening 5, forms the molten steel drop 6 of certain diameter scope.
In the present embodiment, also to comprise circumferentially above sub-material rotating disk 3 and towards the air jet pipe 7 of molten steel drop 6 inject high pressure gas that flown out by discharging opening 5 and the sparge pipe 8 of inject high pressure water, the gases at high pressure that air jet pipe 7 and sparge pipe 8 spray respectively and water under high pressure can impact further to molten steel drop, drop second-time breakage is made to form the drop of smaller szie and obtain larger flying speed, guarantee that drop keeps spherical in cooling procedure, obtain the particulate steel ball that circularity is excellent.
In the present embodiment, the water jet 801 of described sparge pipe 8 and the angle between the puff prot 701 of air jet pipe 7 and horizontal plane are 30 ~ 60 ° and turn to away from sub-material rotating disk 3 side, and the optimal angle of this angle is 45 °.
