Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a sintered flux production process. One is to solve the problem of unstable product quality in the same industry in China, which adopts a separate process of dry and wet stirring and separation; The process of metering and adding; the third is to increase the pre-drying process after granulation to remove the surface of the wet sticky material in view of the situation that the viscous material directly enters the drum dryer and is easy to stick to the wall of the dryer and the mate

Example Embodiment

[0026] An embodiment of the present invention is described with reference to FIG. 1 .

[0027] 1. Flux raw material formula (wt%): MgO+CaO=25%~30%; Al 2 O 3 +MnO=20~30%; SiO 2 +TIO 2 =15%~25%; CaF 2 =15%~25%;;FeO=1%~2%, K 2 O+Na 2 O=2%~3%, S≤0.04%, P≤0.04%.

[0028] 2. Flux preparation process:

[0029] ①Ingredients: After the required raw materials are re-inspected, they are ground into powders of different standard particle sizes, and then sieved and proportioned according to the required formula;

[0030] ②Stirring: Put the well-proportioned raw materials into the dry mixer for dry mixing, stir evenly, and then put it into the wet mixer, add an appropriate amount of water glass for wet mixing; the addition of water glass is carried out by pipeline transportation, and electronic scales are used for automatic metering addition. method.

[0031] ③ Granulation: the fully stirred raw materials are sent to the granulator for granulation;

[0032] ④Pre-drying: Pre-drying...

Abstract

The invention relates to a method for producing sinter solder, which comprises preparing material, mixing, making particles, pre-drying, drying, selecting, sintering, cooling, selecting, magnetic selecting, checking, and packing, wherein the invention uses dry-wet mixing separating technique, to eliminate the dead corner and confirm the uniform product, with stable product quality. And it uses vibration fluidize drying technique to reduce block ratio in drying process under 5%. And it coats anti-adhesive coat on the contact with material. The invention uses left heat recycle technique, to recycle the heat when cooling solder into former processes to dry the semi product. And the energy consumed by roller drier is from the left heat.

Description

technical field [0001] The invention relates to a production process of sintered flux. Background technique [0002] The production process of sintered flux in the prior art is: batching, stirring with water glass, granulation, drying, screening, sintering, cooling, screening, magnetic separation, packaging. Because the raw material of sintered flux is made by adding various mineral powders into the water glass solution, stirring and granulating, and the water glass solution is viscous, so the viscous material made after granulation is sent to the drum for drying. The inside of the machine is easy to stick to the wall of the dryer barrel, the more sticky the thicker it must be cleaned regularly. The cleaning method is to manually or mechanically knock the cylinder wall, which will generate a lot of noise, which not only directly affects the working environment of the workers, but also seriously damages the equipment. After the knock is damaged, the furnace cylinder must be ...
