2. Achieving Optimal Beam Alignment: The Power of Heat Straightening

   At American Crane & Equipment Corporation, we take immense pride in delivering superior quality products and services to our valued customers. As a leading provider of cranes and lifting equipment, we understand the importance of precise engineering and impeccable structural integrity. In our pursuit of excellence, we utilize various techniques to ensure that every component meets the highest standards. One such technique that plays a crucial role in achieving optimal beam alignment is heat straightening. In today’s blog, we will explore the general heat straightening procedure for rolled shapes and frames, shedding light on its benefits and applications within our industry.

   The Heat Straightening Process:

   Heat straightening involves the controlled application of heat to adjust the curvature of rolled steel sections and box girders, ultimately improving dimensional tolerances in terms of camber and sweep. By carefully manipulating the temperature of the steel, we can correct any deviations and align the beams according to our precise specifications.

   Heating Technique:

   To initiate the straightening process, we employ an oxygen-propylene combination with torch equipment fitted with a multi-orifice tip. The size of the torch tip is determined by the fitter based on factors such as base material thickness, the location of the heat pattern, and the magnitude of incremental straightening required. We utilize an oxygen-propylene combination at approximately 20 psi propylene and 60 psi oxygen for optimal results.

   Heat Application:

   The heating process follows a specific pattern to gradually straighten the beam. Predetermined marks are placed on the flange of the member prior to heating. The heat is then applied in a truncated triangle or semi-circular pattern, commencing from the concave side of the member. For a triangular pattern, the heating pattern may begin at the apex and progress towards the base at an included angle of 15 to 45 degrees. Alternatively, for a semi-circular pattern, the heating pattern starts at the flange edge and progresses up to a maximum of 4r, with the base of the pattern not exceeding 12 inches. Between heating cycles, the beam is allowed to cool to a maximum temperature of 250°F before subsequent reheating.

   Temperature Control:

   Careful temperature control is crucial to prevent overheating and ensure the integrity of the steel. The goal is to bring the temperature of the steel to between 1000°F and 1100°F as rapidly as possible without exceeding safe limits. Temperature-sensitive crayons are used to monitor the heat levels, with a minimum temperature range of 1000°F to 1250°F. Any heating that causes the material to exceed 1250°F is deemed unsatisfactory and requires rejection.

   Cooling Methods:

   After reaching a temperature of 600°F, quenching with water is strictly prohibited. Instead, we cool the material using dry compressed air. This controlled cooling process helps maintain the desired alignment achieved through heat straightening.

   Applications and Benefits:

   Heat straightening plays a vital role in our commitment to delivering beams that meet the stringent requirements of our customers. By employing this technique, we can rectify deviations in camber and sweep, ensuring that the rolled steel sections and box girders conform to the precise specifications needed for various applications. The benefits of heat straightening include:

   • Enhanced Structural Integrity: Heat straightening allows us to correct the curvature of beams, thereby improving their dimensional tolerances and overall structural integrity.
   • Precision Alignment: By employing precise heating patterns and temperature control, we can achieve optimal beam alignment, meeting the specific requirements of each project.
   • Cost and Time Efficiency: Heat straightening offers a cost-effective alternative to sourcing new beams, reducing the need for extensive replacements and minimizing project delays.
   • Sustainable Approach: By salvaging and straightening existing beams, we contribute to a sustainable construction approach by reducing waste and conserving resources.
