Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many GH4049 alloy rod.
GH4049 is a Ni-Co-Cr-based deposition hardening deformation superalloy, the application temperature is lower than 950℃. The alloy has good oxidation resistance below 1000°C, and high high-temperature compressive strength below 950°C, which is suitable for the production of natural gas turbocharger blades with operating temperatures ranging from 850°C to 950°C. The key equipment includes hot rolling and forging bar stock and free forging turbine blades.
Application and characteristics of GH4049 superalloy
Alloys have been used to make aircraft engine turbine blades and other high temperature load-bearing parts. After a long period of manufacture and application, it has become one of the most widely used foliar raw materials.
Compared with similar nickel-based alloys in the same way, the alloy's hot working process plasticity is weak, but after electroslag remelting or vacuum pump electric remelting, its production and processing plasticity can be improved, with fracture at 1000 ° C ~ 1170 ° C The toughness is increased by 1~3 times.
Heat treatment process rules and regulations:
1200℃±10℃ heat preservation for 2 hours air cooling+1050℃±10℃ heat preservation for 4 hours air cooling+850℃±10℃ heat preservation for 8 hours air cooling, HB363~302
GH4049 is a nickel-based aging-strengthened alloy with high high temperature strength below 950 degrees, small notch sensitivity, good oxidation resistance and fatigue strength, but poor hot working plasticity. Vacuum consumable or electroslag remelting can improve its heat processing plasticity
GH4049 alloy has been used to make aero-engine turbine blades and other high-temperature load-bearing parts. After long-term production and use test, it has become one of the most widely used blade materials.
The new process of constant temperature toughness rolling is applied to the production practice of GH4049 alloy hot-rolled bars. The production process and product quality are relatively stable, and the products can meet the needs of the market in large quantities, so they have been well evaluated by users, both economic and social benefits. relatively significant.
