What Is a Slickline?

Steel wire is one of the four major varieties of steel plate, tube, shape and wire. It is a reprocessed product made of cold-drawn hot-rolled wire rod.

Steel wire (steel wire) is one of the four major types of steel plates, tubes, shapes, and wires.

The main processes of steel wire production include raw material selection, iron scale removal, drying, coating treatment, heat treatment,

After the wire rod or intermediate wire blank is chemically descaled and coated, it needs to be dried at low temperature to remove hydrogen and moisture. Drying temperature is generally 26 ° C; 300 ° C. The temperature should not be too high to prevent the failure of the lubricating coating. Dehydrogenation is to exclude the hydrogen invading in the steel base during the pickling process, the purpose is to eliminate hydrogen embrittlement and restore the plasticity of the wire rod. The purpose of removing the moisture from the surface of the wire rod and drying it is to prevent the moisture from deteriorating the effect of using the lubricant. There are three commonly used drying facilities:

Drying box

It is a box with an upper cover, and its effective size is determined according to the maximum diameter of the spool. When working, the box is heated with 150 ~ 250 . The drying speed of this equipment is fast, the time is about 2-15 minutes, and the drying is relatively uniform.

Tunnel drying furnace

The combustion chamber under the furnace provides a heat source, and the temperature in the drying chamber can reach about 280 ° C. The bottom of the furnace is covered with trolley tracks and arched cast iron heat sinks. The dried wire rod or intermediate wire blank is hung on a trolley by a boom,

Heat treatment of heat-treated wire rod or steel wire semi-finished products is described in Wire Heat Treatment. Heat treatment includes three types of raw material heat treatment, intermediate heat treatment, and finished product heat treatment.

(1) The heat treatment of raw materials, that is, wire rods, is used in some medium and high carbon steel wires and

Plating treatment A layer of metal or alloy is plated on the surface of the steel wire that needs to be coated on a non-gloss surface. One of the purposes is to prevent the steel wire from corrosion to improve its service life.

According to the shape of the section, there are mainly circles, squares, moments, triangles, ellipses, flat, trapezoids, zigzags, etc. According to the size classification, there are extra fine <0.1 mm, finer 0.1 ~ 0.5 mm, fine 0.5 ~ 1.5 mm, medium 1.5 to 3.0 mm, 3.0 to 6.0 mm thick, 6.0 to 8.0 mm thick, extra thick> 8.0 mm; classified according to strength, low strength <390 MPa, lower strength 390 to 785 MPa, ordinary strength 785 to 1225 Mpa, higher strength 1225 ~ 1960 Mpa, high strength 1960 ~ 3135 Mpa, extra high strength> 3135 Mpa.

Product introduction:

This machine is a new-generation dual-space microcomputer-controlled electronic universal testing machine specially designed for universities and research institutes. test

The design of the main engine and auxiliary equipment draws on the advanced technology from abroad, with beautiful appearance, convenient operation and stable and reliable performance. The computer system uses the Zhongchuang controller to control the rotation of the servo motor through the speed control system. After the deceleration system decelerates, the moving crossbeam is moved up and down by the precision screw pair, and the sample is stretched, compressed, bent, and sheared. Mechanical performance test, pollution-free, low noise, high efficiency, with a very wide speed range and crossbeam moving distance, in addition to a variety of test attachments, in the mechanical performance test of metal, non-metal, composite materials and products, Has a very broad application prospect. This machine is widely used in the inspection and analysis of materials in construction and building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastics, textiles, household appliances and other industries. Ideal test equipment.

This machine adopts the all-digital AC servo speed regulation system with high speed regulation accuracy and stable performance and servo motor as the drive system, the Zhongchuang controller as the core of the control system, and the control and data processing software with WINDOWS as the operating interface to achieve the test force, The screen display of peak test force, beam displacement, test deformation and test curve, all test operations can be completed automatically on the computer with the mouse. Good humanized design makes the test operation easier. Based on the above technologies, the machine can realize closed-loop control of parameters such as test force, deformation and displacement, control modes such as constant stress, constant strain, and constant displacement, and various control modes can be smoothly switched. The machine fully meets the requirements of national standards, and can be tested and data processed according to GB, ISO, JIS, ASTM, DIN and users. It also has good scalability.
