shrinking and re-contracting between the compacted powders.  Process, so that a strong bond between the binding agent particles, so that the products become strong, with a certain degree of hardness and sufficient strength. Most of the blades are made of bronze (Cu-Sn is the king) binder, so they belong to liquid-phase sintering and disappear in the liquid phase at the later stage of sintering. The main component of the liquid phase is low melting point tin. Due to the presence of liquid phase, the sintering speed is increased, the product shrinks significantly, and the density and strength of the product can be improved. 1. Sintering equipment and furnace atmosphere The most commonly used sintering equipment for the saw blade industry is the bell furnace. Its structure is shown in Figure 7-45 above and is 35mm thick.    The iron plate is enclosed in a shell, and the refractory lining is built on it, and the resistance wire is embedded as a heat source. The resistance wire size is determined by the design power of the furnace, and a φ3 5mm stuffed resistance wire is usually used. The design temperature of the bell furnace is usually 850 900 °C. The inner cover is made of heat-resistant stainless steel. Its role is to divide the bell furnace into two parts, inside and outside. The lower edge of the inner cover is inserted into the sealing groove of the furnace seat, so that the inner layer of the furnace forms a closed sintering chamber, facilitating the introduction of shielding gas. The saw blade to be sintered is placed (or placed directly on the furnace)  A sintering chamber. The outer side of the inner cover is a heating system. The outer cover is heated and heated. The heat is transmitted through the air and radiation to heat the sintering chamber and the temperature rises. The furnace seat is provided with a water seal groove, and the water injection in the tank acts as a water seal to prevent the escape of protective gas in the furnace and the entry of air outside the furnace (positive pressure during sintering). A thermocouple is installed at the center and sintered. At the time, the furnace is filled with protective gas to prevent oxidation of the sinter. The most commonly used protective gas is liquid nitrogen.  The solution of hydr.ogen is actually a mixture of hydrog.en and nitrogen. Gas and liquefied petroleum gas can also be used. If there is no condition for preparing a protective gas, the article to be sintered must be buried near the sintered product with charcoal during sintering, and the charcoal particles should be fine. The rest can be filled with larger particles of charcoal. Because of its simple structure, good sealing performance and even temperature distribution in the furnace,  The sintering chamber has a large volume, a large amount of primary sintering, easy operation, safe and reliable operation, small footprint, and high thermal efficiency. It is ideal to use a bell jar to sinter the saw blade. Diamond Drill Bits Set. Now it has become the most common sintering equipment for diamond products. Bell jar furnace temperature gradient is radial distribution. Large-diameter products are stacked in a single row, so when sintering large-diameter products, heat is uniformly distributed in all parts of the diamond layer. Small-diameter products use space as much as possible, and are often stacked in multiple rows, thus easily generating high temperatures on one side. Side temperature  Low phenomenon. Therefore, avoid uneven temperature when installing the furnace. Sintering products can also be used box furnace? The medium and small furnaces of 15 to 40 kW are often used. The box-type electric furnace used in industry is mostly open, that is, the furnace has no airtightness, so the gas protection during sintering cannot be realized, so it needs to be modified. The method of modification is to make a heat-resistant stainless steel furnace   , as shown in Figure 7 - 60 As shown in the figure, when the furnace door is fastened with screws, the furnace chamber is closed and the protective gas can be introduced. The box type electric furnace is characterized by its simple structure, reliable operation,
