The Production of Modern H-Beams using the Sachs Process
The Sachs process is a method of producing modern H-Beams with the use of steel rollers. This process is one of the main techniques used in manufacturing structural steel. It involves rolling round steel bar stock while it is still in a hot and malleable state and then finishing off the product by heating it and straightening it. The use of this process has enabled the production of high-quality H-Beams which are strong enough to be used in a variety of construction applications.
The Sachs process begins by heating the steel bar stock in a furnace up to 1650°F (around 900°C). This temperature is required to reduce the internal grain structure of the steel, thus allowing it to become malleable and flexible. Once the steel reaches the desired temperature, it is ready to be rolled. A four-high rolling mill is typically used to roll the steel. This machine consists of two large steel cylinders that are mounted vertically and two smaller cylinders that are mounted horizontally. As the bar stock is fed in between the two large cylinders, the smaller cylinders move in opposite directions along the length of the stock, progressively reducing its diameter. The duration that it takes to roll the steel depends on the grade of steel, the size of the rollers, and the amount of force required to roll the steel.
The rolled steel is then cut into the desired lengths and heated in a tempering or annealing furnace to help reduce any residual stresses in the steel. Upon cooling, the steel is visually inspected for defects. After any minor defects are rectified, the rolled steel is ready for the final step in the Sachs process. A machine called an end-planer or an end-rounder is used to straighten out the edges of the rolled steel. This is done by using a set of metal cutters to shear the steel down to the desired thickness and to remove any ridges along the edges.
Once this step is complete, the steel can be considered as finished H-Beams. They are then ready to be used in the construction of buildings and other structures. Modern H-Beams made with the Sachs process can be cut and formed easier than traditional H-Beams produced by traditional forging techniques. Thus, this process has revolutionized the production of H-Beams and has allowed them to be used in a wide range of applications. The process is also more energy-efficient and environment-friendly than the traditional ones, making it an ideal choice for manufacturers.
