Miner SteelThe full name is mining I-beam, suitable for mine roadway support. The sold miner steel is also known as steel beam, which is a type of I-beam. Miner steel is divided into ordinary miner steel, light miner steel, and H-beam. Miner steel is widely used in various construction structures, bridge miner steel, vehicle miner steel, support miner steel, mechanical miner steel, etc.

Chinese name: Miner Steel

Miner steel English name: steel I beam

Nickname for miner steel: steel beam

Definition of miner steel: The cross-section shape is miner steel.

Miner steel product specifications: 10#-45# Applicable range: construction sites, decoration, decorative product material: Q235B Length dimensions: 6M, 9M, 12M

Disciplines of miner steel application: Materials Science and Technology; Metal Materials (secondary specialty); Steel Materials (discipline); Steel varieties (fourth-level specialty)

The concept of I-beam is also known as steel beam (English name: I Beam), which is a long steel bar with an I-beam cross-section. Industrial steel is divided into ordinary miner steel, light miner steel, and H-beam.

Industrial steel is widely used in various construction structures, bridges, vehicles, supports, machinery, etc. The flanges of ordinary I-beam and light I-beam gradually thin from the root to the edge and have a certain angle. The models of ordinary miner steel and light miner steel are represented by numbers and include the height of the waist, measured in centimeters. The web thickness, flange thickness, and flange width differ, with specifications represented as waist height (h) × leg width (b) × waist thickness (d) in millimeters, such as "ordinary 160×88×6", which means ordinary I-beam waist height 160mm, leg width 88mm, waist thickness 6mm. "Light industry 160×81×5", which means light industrial steel, waist height 160mm, leg width 81mm, waist thickness 5mm. The specifications of ordinary miner steel can also be represented by models, with models indicating waist circumference in centimeters, such as 16# ordinary worker.

For miner steel with the same waist height, if there are several different leg widths and waist thicknesses, it is necessary to add A-type I-beam, B-type I-beam, and C-type I-beam on the right side, such as ordinary 32# A-type miner steel, 32# B-type miner steel, and 32# C-type I-beam. The specifications of hot-rolled ordinary miner steel are 10-63#. The specifications of hot-rolled ordinary miner steel supplied by both parties are 12-55#.

Production process: Blank preparation → Billet heating → Rolling → Sawing or shearing → Cooling, cooling → Straightening, straightening → Surface cleaning → Packaging materials → Weighing → Packaging materials → Storage.

Material characteristics of miner steel:

Due to the relatively high and narrow cross-section dimensions of ordinary and light I-beams, the difference in the moment of inertia of the two main sleeves of this cross-section is very large. It is not suitable for axially compressed components or components that are bent perpendicular to the web plane, which makes its application range very limited. The use of I-beam should be selected according to the requirements of the design drawings.
