Embodiment Construction
[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0028] A cooling process for steel shot production and processing, using the following process steps:
[0029] S1: Add the raw materials to the smelting furnace by weight, adjust the temperature of the smelting furnace to 1600℃-1700℃, and smelt into an alloy solution;
[0030] S2: Add a refining agent to the alloy solution for refining and slag removal and sampling for inspection;
[0031] S3: The refined alloy solution is added to the rotati...

The invention discloses a producing, machining and cooling technology for steel shots. The technology comprises the following technological steps that S1: raw materials are added to a smelting furnacein parts by weight and are smelted to form an alloy solution; S2: a refining agent is added to the alloy solution for refining and slag removal; S3: the refined alloy solution is added to rotary-conecentrifugal atomizing equipment, so that a metal liquid film is formed on the surface of a rotary cone body and is atomized into tiny molten drops under the effect of centrifugal force and surface tension, and the tiny molten drops are thrown outwards; S4: a cooling medium is ejected in the direction perpendicular to the moving direction of the molten drops, so that the molten drops are granulated quickly and enter a cooling circulating device; S5: the steel shots are taken out, drained, dried, demagnetized and subjected to coarse screening; S6: the steel shots screened in S5 are ground to have edges and corners, and finished steel shot products are obtained; S7: the steel shot products prepared in S5 and S6 are subjected to rust removal and split packaging. According to the technology, the steel shots are produced with the rotary-cone centrifugal atomizing technology used in the existing steel shot production method, so that the problem that the continuity of mass production is not facilitated due to the fact that the steel shots accumulate easily during cooling in the existing technology is solved.
Description
Technical field [0001] The invention relates to the technical field of steel shot production technology, in particular to a steel shot production and processing cooling technology. Background technique [0002] Steel Shot (Steel Shot) is a kind of spherical particles made of special materials through special heat treatment. Steel shot is a commonly used metal workpiece processing material. The steel shot has a tight structure and uniform grain size. Treating the surface of the metal workpiece with steel shot can increase the surface pressure of the metal workpiece and improve the fatigue resistance of the workpiece. . The use of steel shots to treat the surface of metal workpieces has the characteristics of fast cleaning speed. Steel shots and steel grit have appropriate hardness and good resilience. The internal corners and complex shapes of the workpiece can be cleaned uniformly and quickly, shortening the surface treatment time , Improve work efficiency, is a very good surfa...
