UL wire is generally made of general and good quality. According to the steel distribution catalog and usage, wire rods include general low-hot rolled coils, high-quality wire rods, carbon welding rod wire rods, adjustable thread wire rods, steel wire rope wire rods, piano wire rods, stainless steel wire rods, etc.

What is the production process of UL wire?

UL wire is generally produced from ancient ships.

1. Heat the blank to above 1100 degrees Celsius through a walking furnace.

2. After heating, billet oven and high-pressure water descaling;

3. UL wire rod enters the rough rolling mill, which is a hot continuous rolling mill.

4. After rough rolling, it enters the water cooling section to lower the temperature and control the internal metallographic structure.

5. After leaving the water cooling section, it enters the intermediate rolling mill and the finishing rolling mill.

6. After the UL wire rod is finished rolled, it is spit out from the spinning head to form a coil.

7. Coiled wires cooled by air cooling part;

8. At the end of the air cooling section, the wire is shaped into a roll shape by Fuller.

9. Put the reel-shaped wire into the binding device and tie it up.

10. UL wire rods enter the finished product warehouse.

What are the classifications of UL wires?

​

1. General low hot-rolled disc (GB701-65). General low-hot rolled disc is made of low-carbon general carbon structural steel or carbon structural steel with a lower yield point. It is the most commonly used and widely used wire rod among wire rod varieties. (Also called stranded wire).

Main uses: General wire is mainly used to build reinforced concrete structures, and can also be used to make iron wire bindings with cold sugar. UL wire

2. UL wire rods are generally low-twist cold-rolled and hot-connected wire rods (ZBH4403-88). Twist-free cold-rolled and hot-connected wire rods are made by controlled cooling after twist-free high-speed wire rod rolling mills. The materials are the same as general wire rods, but without The advantages of twisted cold-rolled and hot-connected wire rods are high dimensional accuracy, good surface quality and high mechanical properties.

Main uses: torsion controlled cooling. The dimensional accuracy of hot rolled wire rods is divided into three grades: A, B and C. Levels A, B, and C are suitable for drawing, construction, packaging, welding rods, etc. Levels B and C are suitable for processing bolts, screws, nuts, etc.

3. Good quality UL wire (GB4354-84), good quality wire should be of good quality. One of the most widely used types of wires. UL wire

Main uses: 3360 high-quality wire rod is mainly used for processing carbon spring wire rods, oil-quenched and tempered carbon spring wire rods, prestressed wire rods, high-strength and good-quality carbon structural wire rods, galvanized wire rods, galvanized steel wire ropes, etc.

4. Good quality UL wire rods are cold without twisting and hot connected wire rods (ZBH44002-88). Good quality UL wire rods are cold without twisting and hot connected wire rods are rolled in a high-speed wire rod rolling mill and then subjected to controlled cooling. Compared with good quality wire, it has high dimensional accuracy, excellent surface quality and high mechanical properties.

The main purpose of UL wire is the same as that of good quality wire. Commonly used to manufacture carbon spring wire, oil quenched and tempered carbon spring wire, prestressed wire, high-quality carbon structural wire, galvanized wire, etc. 5. Rope manufacturing marine wire rod (YB349-64), rope manufacturing marine wire rod is one of the best quality carbon structural steel hot-rolled discs.

Main uses of UL wire: Joule manufacturing wire can be made of good quality carbon structural steel of 35, 40, 45, 55, 60, 65, 70, 75, 80, 85 steel. The chemical composition complies with the requirements of GB699 (Technical Conditions for Good Quality Carbon Structural Steel).
