Forging is a common forming method in mechanical manufacturing. The as-cast looseness and welding holes of the metal can be eliminated by forging, and the mechanical properties of forgings are generally better than castings of the same material. For important parts with high load and severe working conditions in machinery, forgings are mostly used except for plates, profiles or weldments that can be rolled with simple shapes.Vacuum Oil Quenching for steel hardening heat treatment Forging can be divided into cold forging and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the blank metal. Sometimes it is also called warm forging when it is heated but the temperature does not exceed the recrystallization temperature. However, this division is not completely uniform in production.MIM degreasing and sintering for ceramic hard alloy The recrystallization temperature of steel is about 460°C, but 800°C is generally used as the dividing line, and hot forging is above 800°C; it is called warm forging or semi-hot forging between 300 and 800°C.X6325A UNIVERSAL TURRET MILLING MACHINE Forging materials are mainly carbon steel and alloy steel with various components, followed by aluminum, magnesium, copper, titanium and their alloys. The original state of the material is bar stock, ingot, metal powder and liquid metal.X6325 X6325C X6325D UNIVERSAL TURRET MILLING MACHINE

The wear of the pipe wall is closely related to the concentration of solid materials in the airflow, the velocity of the flue gas, the characteristic hardness of the particles, and the geometry of the flow path. According to relevant research data, the amount of scouring wear is approximately proportional to the 3.6th power of the airflow velocity.Study on Vacuum Brazing Technology of Silver-Cu-Based Solder In CFB boilers, the concentration of solid materials is huge, usually up to dozens to hundreds of times that of pulverized coal boilers, and the flue gas flow rate is large, the particles are hard and sharp-edged, so driven by the high-speed flue gas, the CFB boiler The erosion and wear of the heating surface such as the water cooling wall is extremely serious.Vacuum carburizing of aviation gear steel Especially at the water wall at the top of the retaining wall, because it is located at the edge of the dense phase zone, it is not only strongly scoured and worn by the high-speed and high-concentration bed material and fuel airflow, but also has serious eddy current effect, cutting effect and centrifugal effect.HORIZONTAL MITRE BAND SAW MACHINE BS-460G The eddy current effect is at the four corners of the furnace. Because the side wall flow is formed here, more materials gather here. Due to the inertia of solid particles, the local wear is particularly obvious, and the cutting effect is reflected in the water wall at the root of the retaining wall. The reason is that Since the top of the protective wall provides a platform.HORIZONTAL MITRE BAND SAW MACHINE BS-460GB
