Production processes of nm500 plate thickness size
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the NM500 plate thickness size steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
Jspl announced plans to build a 2.5-million-ton-a-year NM500 plate thickness size steel plant in the ramga region of the Indian state of Jharkhand. It is reported that the company has a wire mill, a bar mill and a steel service center in the region. The new steel plant is expected to be put into operation in two to three years. The completion of the new NM500 plate thickness size steel plant will be conducive to its integration and elimination of backward production capacity.
The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as NM500 plate thickness size. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.
For wear-resistant steel plate, it is not the higher the hardness, the better the wear resistance! Hardness is the basis of excellent wear resistance of NM500 plate thickness size, wear-resistant steel plate, but the relationship between hardness and wear resistance is not in direct proportion. The reason why wear-resistant steel plates are wear-resistant is that they have hard particles and soft matrix. Generally, in the process of wear, there will be some falling substances, which will be incorporated into the soft matrix and will not cause great damage to the surface.
