specific Embodiment approach 1

[0045] DETAILED DESCRIPTION one: one kind of a wire according to the present embodiment nonmetallic inclusions embodiment test sample sampling method to ≤6mm φ5.5mm≤ wire diameter wire, for example, according to the GB / T10561-2005 sample 3 "diameter or side length of less than 25mm of steel rod, through the entire testing side cross-sectional diameter, its length should give assurance about 200mm 2 Test area ", the first plurality of wire 40mm taken as a sample;

[0046] A plurality of sample was then placed on a magnetic chuck metal base, φ5.5mm≤ sample using DIAMETER ≤6mm radius R 1 The semi-cylindrical groove, the grinding dimensions of 2.75 ~ 3mm, per 30 samples can be mounted on the metal base segments, the use of 30 sample grinder for grinding segments need 40min, the processing time for a single sample period an average of about is 1.3min;

[0047] If the sampling method of the conventional sampling method, the grinding machine to wire cutting, the remaining steps uncha...

specific Embodiment approach 2

[0048] DETAILED DESCRIPTION two: one kind of a wire according to the present embodiment nonmetallic inclusions embodiment of sampling specimens for testing to φ6mm ≤8mm wire 2 The inspection area is therefore first takes a number of 30-35 mm wires as a sample;

[0049] The plurality of samples are placed on the metal base on the electromagnetic suction cup, φ6mm 2 The semi-cylindrical slot, the grinding size is 3-4 mm, 35 test sections per metal base, using grinding machines for 35 test segments to be worn for 50 min, and the processing time of single sample segment is about 3 1.4min;

[0050] If the sample method is the existing sampling method, the grinding machine is changed to the wire cutting process, the remaining steps are not changed, and the wire cutting of the wire diameter ≤ 8 mm is as an example. The line cutting length is 6-8 mm, the length of the sample section is 30 -35mm, each processing can be installed with a sample segment, each sample processing time of 18 min....

specific Embodiment approach 3

[0051] DETAILED DESCRIPTION OF THE INVENTION 3: Sampling method of a wire non-metal clamp detection sample according to the present embodiment, as an example of φ8 mm 2 The inspection area is therefore first takes a number of wires 20-25mm as a sample;

[0052] The plurality of samples are placed on the metal base on the electromagnetic suction cup, φ8mm 3 The semi-cylindrical slot, the grinding size is 4-5mm, 40 test segments per time on the metal base are installed, and 40 test segments are used to abrasive for 1 h, and the machining time of a single sample section is approximately. 1.5 min;

[0053] If the sample method is the existing sampling method, the grinding machine is changed to the wire cutting process, the remaining steps are not changed, and the wire is used as an example of φ8mm

Abstract

The invention discloses a sampling method of a sample for wire rod non-metallic inclusion inspection, and belongs to the field of wire rod non-metallic inclusion inspection methods. According to the invention, the problems of low wire rod inspection efficiency and high wire rod inspection cost caused by a sampling method for wire rod inspection in the prior art are solved. The sampling method provided by the invention comprises the following steps: sampling a material section, designing a metal base for placing a sample section, and processing, grinding, embedding, manually grinding, cleaning and drying the sample section. By means of the sampling method of the sample for wire rod non-metallic inclusion inspection, the sampling time of the wire rod for inspection can be effectively prolonged, and compared with traditional wire cutting, the sampling time is shortened, the wire rod testing efficiency is improved, and the wire rod sampling cost is reduced.

Description

Technical field [0001] The present invention relates to a method for sampling a wire belongs to the field test methods nonmetallic inclusions in the wire. Background technique [0002] Is a minimum wire size of the hot-rolled steel section, the typical diameter of 5 to 9 mm were rolled round eight kinds of specifications is called the wire supply rolls. Due to the delivery wire coil, it is also known rod. Foreign wire and the concept of slightly different, in addition to a circular cross section may also have other shapes, where the diameter thereof due to the different needs of production technology and inconsistent. Depending on the high-speed wire mill can be divided into two kinds, and ordinary wire, the wire is generally made of ordinary carbon steel and high carbon steel. Steel according to different directories and distribution purposes, including ordinary low carbon steel wire rods hot-rolled, high-carbon steel wire rod, carbon rod electrode, quenching the threaded rod, w...
