Effective Ways to Assess Shear Blade Welding Quality

In order to ensure shear blade welding quality, the welded blades should be carefully inspected to identify the cause of defects and make improvements. Before inspection, the blade should be sandblasted or lightly ground to remove solder and impurities adhering to the surface of the blade, and cleaned with kerosene. The inspection items and requirements are as follows:

1、Check weld strength: Use a green silicon carbide grinding wheel to grind the back of a blade and check the thickness of the solder layer, which should be below 0.15 millimeters. There should be no air holes or insufficient solder at the bottom surface of the tool tip support. The weld seam that is not filled with solder should not exceed one tenth of the total length of the weld seam. If there are pores, the blade will fall off during cutting.

2、 Check the position of the shear blade in the slot: if the blade is misaligned or sagging beyond the technical specifications, it should be re welded.

3、 Check welding strength: Use a wooden hammer or copper hammer to strike the blade with moderate force, or use an I-hammer to strike the blade with strong force. If the blade does not fall off from the blade body, it is considered qualified. Checking the welding strength of the blades may not be done individually, and spot checks are also used.

4、 Check the flatness of the blade: If there are obvious pits on the blade, it indicates that the blade is overheated and deformed, and should be burned down and re welded with a new blade.

5、 Check for cracks: After cleaning the blade with kerosene, if there are cracks, kerosene will penetrate into the cracks and black lines will appear, which can be observed with the naked eye. It can also be observed with a magnifying glass of 10-40 times.

Silicon carbide boasts high thermal conductivity and low coefficient of thermal expansion. Due to its chemical stability and strength, low density specific gravity, excellent wear resistance properties and corrosion resistant qualities, and excellent wear resistance characteristics it makes an excellent material choice for industrial furnaces, chemical machinery and equipment, electrical power generation plants, aerospace & defense applications.

At high temperatures, its excellent resistance to creep and thermal shock makes it suitable for high-temperature refractory applications such as burner nozzles, aluminium crucibles for aluminium smelting and flue gas desulphurization tubes. Furthermore, its corrosion and oxidation resistance and mechanical strength makes it useful in shed boards used in ceramic product firing kilns, vertical cylinder distillation furnace lining for zinc smelting, as well as steel and aluminum electrolytic cells.

Boron addition produces porous silicon carbide with superior electrical and thermal conductivity as well as flexural strengths, when nitrogen-sintered. When doped with various amounts of beryllium doping, some of it entrained within crystal grains serves as an acceptor and converts these crystals to p-type semiconductors. Foam Materials

Silicon carbide foam ceramics are ideal for demanding applications due to their combination of physical properties, including corrosion resistance, temperature stability, liquid permeability and high young modulus. They are currently utilized in combustion burners, sensors, molten metal filters and catalyst supports as well as pipeline systems and erosion protection applications.

Foaming of SiC is generally accomplished via gel-casting, wherein a colloidal ceramic suspension containing water-soluble monomers and a foaming agent is polymerized by decomposing them into gasses and solids (Figure 3). As shown, bubbles form, creating an enormous surface area per volume while still maintaining high mechanical strength (as depicted). This approach makes possible an extremely low bulk density while still maintaining strong mechanical integrity (as illustrated).

Rheological measurement methods are available to analyze the flow behavior and material properties of these slurries, as well as create foams of various recipes with different porosities; Duocel(r) foam boasts superior thermal conductivity due to its large free surface area compared with its volume.
