Product Description
Stainless steel bars are hot rolled or forged from stainless steel ingots.
The production of stainless steel bars emerged with the development of stainless steel. Due to the increasingly wide range of applications of stainless steel bars, such as the foundation of high-rise buildings in cold areas, isolation nets beside highways, household items, etc., the hot-rolled production of stainless steel bars has been greatly developed. 30% of stainless steel products in my country %, foreign countries only account for 8%-10%. With the rapid development of cutting-edge technologies such as petroleum, chemical industry, energy and atomic energy, aerospace, and marine development, higher comprehensive performance requirements have been put forward for stainless steel, which not only requires good corrosion resistance, but also requires high strength, high temperature and high pressure resistance. , radiation resistance, low temperature resistance and other properties, so that the types of stainless steel have been further developed.
Use
Mainly used for aircraft engine blades, casings, fasteners, combustion chambers, discs, shafts, combustion chamber walls, liquid oxygen kerosene engines, bomb bodies, gas cylinders, propulsion devices, etc. Widely used in aerospace, aviation, atomic energy, nuclear energy, petroleum, chemical industry, and food, environmental protection, marine development, boiler heat exchangers and other fields.
The cross-sectional shape of the bar is simple, and it is much larger than the general cross-section of the wire, so the heat dissipation is slow, the allowable rolling time is long, and the problem of large temperature difference between the head and the tail is not prominent, but the upper limit product is prone to insufficient compression ratio. Like other hot rolling, in order to be able to roll products with high dimensional accuracy, it is necessary to ensure that the heating is uniform and consistent, the stiffness of the rolling mill is as high as possible, and the cooling is consistent during rolling. There are also changes in the pass shape caused by wear during rolling, which affects the lasting stability of rolling.
The modern national economy contains many sectors, such as industry, agriculture, transportation, construction, commerce, health, etc., which are all important components of the national economy. The metallurgical industry is an important part of modern industry. The metallurgical industry provides high-quality raw materials for the machinery manufacturing industry, and the machinery industry in turn can provide excellent mechanical equipment for other industries
