Introduction
The YB/T5100-1993 Piano Wire Strand is a type of steel strand made of cold-drawn high-carbon steel wire and manufactured in accordance with the standard requirements of YB/T5100-1993. It is mainly used in high-tension cords, express train passenger envelopes, elevator ropes, and mine hoists for protecting passengers, vehicles and articles from unexpected breaking or slipping. In order to introduce the basic information of this type of steel strand, this paper will discuss its material, structure, production process and performance, as well as its application scope and standard requirements.
Material
The material of the piano wire strand is cold-drawn high-carbon steel wire, which needs to meet the requirements of the standard for chemical composition, mechanical properties and other relevant parameters. The chemical composition of the steel wire should meet the standard requirement of GB/T699-1988 or equivalent, the tensile strength of the steel wire should be not less than 1000Mpa, and the yield strength should be not less than 850MPa. The steel wire should also have the appropriate elongation and good toughness.
Structure
The piano wire strand is composed of a steel wire with a round cross section, a steel bar and a strand wrapping piece, as shown in Figure 1. The steel wire with a round cross section is the basic component of the piano wire strand, and the other components are used to enhance the strength and stability of the steel wire. The steel bar is used to fix the wrapping piece, and the wrapping piece is used to wrap around the steel wire to give it an overall structure.

Production Process
The production process of the piano wire strand consists of six steps. Firstly, the steel wire needs to be sheared into the desired length, straightened and then welded together to form a round steel pipe. Secondly, the round steel pipe needs to be rolled and drawn into a rectangular steel pipe. Thirdly, the rectangular pipe needs to be stranded with the steel bar and wrapping piece. Fourthly, the stranding process needs to be followed closely by a heat treatment process to ensure the final performance of the steel strand. Fifthly, the entire piano wire strand needs to be cleaned to remove any dust, oil or other impurities. Lastly, the piano wire strand needs to be inspected and tested to ensure that it meets the requirements of the standard.
Performance
The performance of the piano wire strand depends on its material and structure. The material of the steel wire affects its strength, wear resistance, tensile strength, and elongation. The structure of the piano wire strand affects its stability, tensile strength, and elongation. The standard requires the piano wire strand to have a tensile strength of at least 3200MPa, a breaking force of at least 1650MPa, and an elongation of more than 5%.
Application Scope
The piano wire strand can be used in high-tension cords, express train passenger envelopes, elevator ropes, mine hoists and other related products. It is mainly used as the main force bearing part for the safety and dependability of these products.
Standard Requirements
The YB/T5100-1993 standard requires the use of high-quality raw materials, specifies the requirements for the appearance, structure and chemical composition of the piano wire strand, and sets standards for the tensile strength, breaking force and elongation of the piano wire strand.
Conclusion
In conclusion, this paper introduces the basic information of YB/T5100-1993 Piano Wire Strand, including its structure, material, production process and performance, as well as its application scope and standard requirements. It is believed that this paper can help buyers understand the YB/T5100-1993 Piano Wire Strand more clearly and make better selection when they purchase it.
