Gr1 Gr2 Gr5 Titanium Channel Cold Or Hot Rolling ASTM B348 / ASME B348

Product Specification

Technology:

The invention relates to a production method for a titanium alloy U profile, belonging to the technical field of metal processing. Including the following steps :1. The raw material is titanium alloy round rod blank; 2. The bar is heated by a box-type resistance furnace and rolled into a square bar; 3. Use the ultrasonic flaw detection machine, and use the portable grinder to grind the surface; 4. Rolling; 5. Surface repair; 6. Pull and straighten with tension straightener; 7. Alkali pickling surface; 8. Then use the ultrasonic inspection machine for inspection.

The structure and characteristics of the U-shaped slot

1. U-shaped groove is a U-shaped steel with a cross-section, a variety of dimensions and specifications, usually made of hot rolled or cold bending.

2, U-shaped groove has high strength and stiffness, can withstand greater pressure, weight and impact.

3, U-shaped groove surface after rust treatment, with good corrosion resistance and weather resistance.

Second, the function of the U-shaped slot

1, load-bearing function: U-shaped slot can be used as the main load-bearing structure of the floor and roof plate, bearing the building's own weight and load.

2, support function: U-shaped groove can be used as a support structure, used to support the wall, roof and laminate of the building.

3, heat insulation function: the inside of the U-shaped slot can be filled with heat insulation material, play the role of heat insulation, improve the energy efficiency of the building.

Three, the use of U-shaped groove

1, building engineering: U-shaped trough is widely used in building engineering floor, roof and support structure.

2, road bridge: U-shaped groove can be used as a structure component of the bridge, used to carry the vehicle and pedestrian load of the bridge floor.

3, prefabricated building: U-shaped slot can be used as the main structural material of prefabricated building, improve the construction efficiency and quality of the building.

The strength of titanium is large, and the tensile strength of pure titanium can reach 180kg/mm². Some steels are stronger than titanium alloys, but the specific strength of titanium alloys (the ratio of tensile strength to density) exceeds that of high-quality steels. Titanium alloy has good heat resistance, low temperature toughness and fracture toughness, so it is often used as aircraft engine parts and rocket and missile structural parts. Titanium alloys can also be used as fuel and oxidizer storage tanks and high-pressure vessels. It is now used to make automatic rifles, mortar mounts and recoilless gun tubes. In the petroleum industry, it is mainly used for various vessels, reactors, heat exchangers, distillation towers, pipelines, pumps and valves. Titanium can be used as electrodes and condensers in power stations and as environmental pollution control devices. Ti-ni shape memory alloys have been widely used in instrumentation. In medical treatment, titanium can be used as artificial bones and various utensils. Titanium is also a deoxidizer in steelmaking and a component of stainless steel and alloy steel. Titanium dioxide is a good raw material for pigments and paints. Titanium carbide, carbon (hydrogen) titanium is a new type of cemented carbide material. Titanium nitride color is close to gold, and it is widely used in decoration.

Titanium and titanium alloys are widely used in the aviation industry, known as "space metal"; In addition, it is increasingly widely used in shipbuilding industry, chemical industry, manufacturing mechanical parts, telecommunications equipment, cemented carbide and so on.
