In the field of metal pressure processing, hot rolling causes plastic deformation of the metal through a rolling mill above the metal’s recrystallization temperature. The hot rolling process generally includes heating of raw materials, rolling of raw materials, cooling of finished products, and segmented packaging of finished products. Bar is a product of hot rolling. During the hot rolling process, bending will occur. Even after later straightening, it still cannot meet the requirements, resulting in batches of waste products. Causes of Bar Bending During Rolling Generally, the reasons for the bending of rolled parts are uneven cooling speed and inconsistent shrinkage during hot rolling; uneven heating temperature of raw materials; improper installation of rolling mill accessories during hot rolling, etc. At present, wire bar rolling control bending generally adopts online real-time control during the rolling process, such as adjusting the inlet and outlet guide devices of the rolling mill and optimizing the pass pressure configuration. However, due to the uneven temperature of the blank, the temperature difference between the head and the tail, and the uneven wear of the hole, the final control effect is not obvious. Solution There is a way to avoid bending of the bar during rolling....
An induction furnace for steel melting is a device that uses the principle of electromagnetic induction to heat and melt metal. It mainly consists of an induction coil, power supply, and furnace body. The induction coil is driven by the power supply to generate a high-frequency electromagnetic field, and the metal is heated and melted under the action of the electromagnetic field. Types of Induction Furnaces for Steel Melting Induction furnaces for steel melting mainly include the following types. Industrial frequency induction furnace: It uses an industrial frequency power supply for smelting. It is mainly used for smelting various cast iron and cast steel, mainly producing castings, with a capacity of 1.0~100t. Medium frequency induction furnace: uses a silicon-controlled frequency converter or frequency multiplier as the power supply to increase the frequency from 50HZ (60HZ) to 150~4000HZ. It is an important branch of the induction furnace and is mainly used for smelting special steel. The furnace capacity is 0.10~40t. Vacuum induction furnace: A furnace type that is smelted and poured in a vacuum. The power supply is similar to that of a medium-frequency induction furnace. It is mainly used for smelting special steel and alloys. The furnace capacity is 0.05~60t....
Metal casting involves injecting liquid metal into a mold to obtain a metal product in the desired shape. Metal Casting Methods In actual operation, metal casting methods include sand casting, investment casting, lost foam casting, metal mold casting, centrifugal casting, and pressure casting. These methods use gravity to fill the mold, and mold-making is a vital part of the entire production process. At the same time, due to the slow heat dissipation of the mold and the long cooling time, the casting production cycle time is also long. In addition, there is another metal casting method called continuous casting or strand casting. Continuous casting is to pour molten metal into the crystallizer of the continuous casting machine, and then continuously pull out the surface-solidified casting from the other end of the crystallizer. Continuous casting can produce billets or rods of any length. Sand Casting Process: Sand casting is a method of casting using a sand mold. The specific process needs several steps, including making a sand mold, injecting molten metal, cooling and solidifying, destroying the sand mold, and taking out the casting. Features: Sand casting has the advantages of low cost, short production cycle, and wide application range, but its...
With an aluminum melting furnace, we can frequently find a closed cooling tower. Apparently, we know what the closed cooling tower is used for. We just know it, but don’t know why and how it works. In this article, we will tell you there. A closed cooling tower is a type of cooling equipment. Its working principle is to ensure the cooling effect by utilizing the heat exchange between circulating air, spray water and circulating water. This type of cooling tower places a tubular heat exchanger inside the tower to achieve a cooling effect through heat exchange with air and spray water. Because it is a closed cycle, it can ensure that the water quality is not polluted, well protect the efficient operation of the main equipment, and improve the service life.

Selecting a steel casting line requires careful consideration of various factors to ensure that the chosen equipment meets your specific requirements. Here are some key steps to guide you in the selection process. Determine Casting Requirements Begin by clearly defining your casting requirements. Consider factors such as the size and complexity of the castings, the desired material properties, the required production volume, and any specific industry standards or regulations that need to be met. This will help you understand the capabilities and specifications needed for the casting line. Assess Production Capacity Evaluate your anticipated production volume and frequency. Determine the capacity and throughput required from the casting line to meet your production targets. Consider factors such as cycle time, number of molds produced per hour, and overall production efficiency. Evaluate Casting Techniques Familiarize yourself with various casting techniques available in the market, such as sand casting, investment casting, or continuous casting. Each technique has its advantages and limitations, and selecting the most suitable one depends on factors such as casting complexity, material properties, and cost considerations. Research Equipment Suppliers Conduct thorough research and identify reputable suppliers or manufacturers of steel casting lines. Look for suppliers with a proven track record,...
