ANTO Mining W Steel Strip/Band

The W-shaped steel belt is a relatively new type of mine support material. The mine-used W-shaped steel belt is the main component of the anchor mesh support system. The mine-used W-shaped steel belt is the cornerstone of the overall structure of the roof. The commonly used steel belts for important means include mining W-shaped steel belts, flat steel belts with swallow-shaped wing-shaped steel belts, and reinforced trapezoidal π-shaped steel belts.

Among them, the W-shaped steel strip for mining is used for the special steel product that the steel strip is continuously cold-formed and rolled by using multiple sets of rollers. Because the steel strip produces a hardening effect during the process of cold-bending into a pad, the hardness of the plastic steel increases by 2 l0%-15% % Therefore, the large roof protection area of the mine W-shaped steel belt is especially suitable for using a large moment of inertia when there are many cracks but the roof pressure is not too large.

The Mine W-shaped steel belt has high rigidity and good bending performance, and the utilization rate of the cross-sectional area is relatively high, which basically meets the requirements of the bolt support for the performance of the steel belt. Compared with the flat steel strip, the w steel strip not only increases the flexural section modulus by 37 times, but also increases the stiffness by 70 times, and also increases the tensile strength by 12%--15% during the cold rolling process.
