It is imperative to remove the furnace scale from forged fasteners

During the forging process of fasteners, a problem that cannot be ignored has quietly emerged - the formation of furnace scale. As a seasoned participant in the industry, LITAI Technology has deeply analyzed the significance of removing this type of scale.
When the fastener blanks are heated in the furnace, the oxidizing gases inside the furnace react rapidly with the metal surface, and the furnace scale is thus formed. Although these scales seem to be just a thin covering, they are actually very harmful. From the appearance, if the scale is not removed during forging, it is very likely to be pressed into the surface of the fastener, forming ugly pockmarks and pits, which greatly affects the appearance and surface flatness of the product. For applications with strict appearance requirements, this is undoubtedly a fatal defect.
The negative impact of oxide scale is far beyond the surface. Due to its high hardness, during the forging process, it acts like tiny abrasive particles, accelerating the wear of the die. Frequent friction causes premature wear and deformation of the die cavity, not only increasing the die replacement frequency and raising production costs, but also possibly leading to a decline in die accuracy, resulting in dimensional deviations of fasteners and affecting the stability of product quality. In subsequent processing stages, oxide scale also causes trouble. During mechanical processing, it intensifies the wear of cutting tools, shortens their service life, and increases processing and time costs. Moreover, if oxide scale remains on the surface of fasteners and enters the heat treatment stage, it will impede the uniform transfer of heat, causing non-uniformity in the structure and properties of fasteners, such as inconsistent hardness, which seriously affects the comprehensive mechanical properties and service life of the products.
So, how to effectively deal with the problem of furnace scale? LITAI Technology has provided the answer. The high-pressure water descaling equipment it launched utilizes the powerful impact force of ultra-high-pressure water jets to create erosion, peeling and thermal explosion effects on the surface of the scale. When the high-temperature fastener billets with scale pass through the descaling equipment, the high-pressure water instantly impacts the scale, causing it to quickly separate from the base material and be washed away. This method is efficient and environmentally friendly, and can thoroughly remove the scale without damaging the base material, laying a good foundation for subsequent forging processes.
The removal of furnace scale during the forging of fasteners is of utmost urgency. With the advanced descaling technology and equipment from LITAI Technology, forging enterprises can effectively enhance product quality, reduce production costs, gain a competitive edge in the fierce market competition, and produce higher-quality and more reliable fastener products.
