Abstract

The invention discloses a guide and guard beam device for hot-rolled section steel. The guide and guard beam device includes a guide and guard beam, and the guide and guard beam is prepared from ingredients with the following mass percentages: 3.6-5.2% Cr-Fe, 2.25‑3.36% B‑Fe, 3.33‑4.56% Mo‑Fe, 1.25‑2.22% Ti‑Fe, 1.85‑2.37% Si‑Fe, 4.5‑4.85% Al‑Fe, 0.75‑0.88% Carburizing agent, 0.8-1.0% ferromanganese, 0.63-0.82% nickel-chromium cast iron, 1.25-2.7% tungsten iron, 0.06-0.15% high-purity scandium alloy, 0.15-0.30% rare earth magnesium alloy, and the balance is iron ; Through the preparation method of the guide beam, the present invention can manufacture a guide beam with excellent performance and excellent wear resistance, and has a strong bearing capacity.

Description

technical field [0001] The invention belongs to the field of crossbeams, and relates to a hot-rolled section steel guide, in particular to a crossbeam device for hot-rolled section steel guides. Background technique [0002] In the field of hot-rolled section steel, the guide system of the blanking machine includes an import guide system and an export guide system. Both the import guide system and the export guide system are composed of four parts: leg knife, waist knife, standing board and beam. The beam is the most basic part of the whole guide system, which plays the role of support and load bearing. According to the number of passes on the roll and the height of the passes, multiple station plates are fixed on the beam. The current beam is a rectangular parallelepiped beam. Since the size of each pass (cutting depth) is different, a set of guides for a rolling mill needs to be prepared with a variety of station plates (including different specifications and spare parts...
