Benefits of technology

This patented technical effect described in this patents relates to improving the performance and productivity of producing complex structures made from materials like carbon fiber composites (CF), ceramics or metal matrix composite(MMC). These techniques involve continuously create stronger components that require less material compared to traditional methods such as cold pressing or welded joints. Additionally, they allow for efficient processing without generating excessive costs due to their large volume. Overall, these improvements result in better economic benefits through enhanced energy utilization during industrial applications while also being able to produce advanced forms at competitive prices.

Problems solved by technology

Technological Problem: The technical problem addressed in this patents relates to improving the performance and durability of materials like concrete or metal structures during their lifespan due to factors including high temperatures caused by heat from various sources, poor design practice methods, heavy loads needed for shipping, limited space available for storage, and difficulties associated with traditional thermal processing techniques requiring long cool down times.

Embodiment Construction

[0029] Specific embodiments of the present invention, such as figure 1 , 2 Shown, a kind of ultra-high-strength steel hot roll forming method, comprises the following steps:

[0030] ①. Send the sheet 4 at normal temperature to the feeding port of the heating conveyor 3;

[0031] ② After the sheet 4 enters the heating conveyor 3, it is continuously heated by the high-temperature heater 7, and the temperature controller 8 is used to control the temperature of the entire heating conveyor 3, so that the sheet 4 is completely austenitized in the heating conveyor 3 , the temperature is controlled at 800-1200°C, and the holding time is 3-10 minutes;

[0032] ③. After the sheet material 4 comes out from the discharge port of the heating conveyor 3, it is directly conveyed into the roll forming machine 2, and the high temperature heater 7 and the temperature controller 8 provided in the roll forming machine 2 ensure that the sheet material 4 is in the whole Keep the same temperatur...

Abstract

The invention provides a method and a device for hot rolling forming of super-strength steel. Compared with the prior art, the method overcomes defects of an existing hot stamping and normal-temperature rolling forming method for super-strength steel. According to the characteristics of super-strength steel, a super-strength steel hot rolling forming technology with good heating efficiency is designed. By means of the method, the strength of a formed part can be multiplied, few waste defective goods are produced, the quality is stable and reliable, the continuous production requirements of a modern enterprise are met, the production efficiency is improved, rebounding deformation of the formed part is controlled effectively by a cooling device, and better engineering application value is realized.
