The processing of special-shaped stone needs to be polished and polished, such as pillars, stigmas, carvings, lines, steps, countertops, arches, window sills, door frames, stone benches, stone tables, wash basins, etc. Nowadays, many stone processing plants are equipped with mechanical aids.
The advantages and disadvantages of using mechanical sanding are as follows:
First, the advantages of mechanical polishing stone polishing:
1. The consistency of grinding is good, the lines of different sizes can be installed in disorder, and have good interchangeability;
2, the polished line has no waves, the surface is flat and the straightness is very good;
3, used to polish the rotary body products with good arc degree, high luminosity; high efficiency;
4. Reduce the labor intensity of polishing and polishing operations;
5. Improve the working environment of polishing and polishing;
6, suitable for pipeline production;
Second, the mechanical polishing stone polishing defects:
1. The initial investment is high, requiring a certain amount of equipment, work space, and forming grinding wheel;
2, lack of certain flexibility, only suitable for large quantities of products;
3, for the different line types to make the corresponding forming tools, and the tool from the rough grinding, fine grinding, polishing and other series of grinding wheels are indispensable;
4. It is easy to break when polishing and slender lines;
5. The grinding wheel for polishing and polishing should be produced by professional manufacturers, and the precision of the forming wheel is high;
6, polishing and polishing the line luminosity is not very high, the surface of the line will have a trace of grinding and polishing marks affecting the appearance of the product, this mechanical polishing and polishing lines have the biggest shortcomings, but also need to solve the problem;
7, not suitable for sanding easily broken stone.
Third, polished stone polishing steps and points of attention:
1. Check whether the shape of the product conforms to the single shape of the production process, and it can enter the polishing process after passing the test;
2. Grinding and polishing the material of the foresight material for the glue treatment, and then grinding and polishing after the glue treatment is good;
3, first single-line drawing line to rough grinding, leaving 0.5MM fine grinding, water grinding allowance when rough grinding; splicing: will be polished and polished lines according to the installation diagram, and according to the surface color of the line to choose to ensure good color, pattern effect. After the line water mill 500#, the number is first unified according to the installation drawing requirements, and then the polishing is removed. This will not cause the interface of the polished and polished lines to be concave and convex;
4. When there is a misalignment at the interface, the distance of the transition section should be lengthened, the longer the better, and the straightness should be checked by the ruler when grinding;
5. After finishing the polishing and polishing lines, the quality inspection can pass the inspection;
6. Grinding and polishing of special-shaped handicrafts to improve luminosity and reduce wave breaks:
7. Choose a polishing material;
8. When polishing and polishing, each abrasive or grinding disc should be carefully inspected and polished to the polished surface after grinding and polishing. After the grinding, the latter should cover up the traces of the previous abrasive.
9, should pay attention to the water quantity control when polishing and polishing, the water quantity is insufficient to cause the smooth surface to be burnt;
10. When grinding and polishing, try to lengthen along the direction of the line, as long as possible, so as to avoid ripples;
11, the speed of polishing is faster;
12. Grinding and polishing electric tools with high speed;
13. It is best to use large-sized lines for polishing and polishing. This can reduce the amount of rough grinding work, and ensure that the lines are rough and have good quality and shape consistency.
Ferro Molybdenum
Ferro Molybdenum composed of molybdenum and iron, generally containing 50 to 60% of molybdenum, are used as alloying additives for steelmaking. Ferro molybdenum is an alloy of molybdenum and iron. Its main use is as a molybdenum addition agent in steelmaking. The addition of molybdenum to the steel allows the steel to have a uniform fine-grained structure and increase the hardenability of the steel, which is beneficial to the elimination of temper brittleness. In high-speed steel, molybdenum can replace a portion of tungsten. Molybdenum is used in combination with other alloying elements to produce stainless steels, heat-resistant steels, acid-resistant steels and tool steels, as well as alloys with special physical properties. Molybdenum added to cast iron can increase its strength and wear resistance.
