Heat-resistant steel shield castings
Heat-resistant steel protective cover has the characteristics of high temperature resistance, oxidation resistance and heat-fatigue resistance. Its design should take into account the high temperature resistance (usually 800 C~1200 C), corrosion resistance, lightweight, and meet the requirements of environmental protection. Material is commonly used in 1.4828 heat-resistant steel. Major uses include protecting equipment components from high temperature damage, preventing heat loss, or isolating high temperature areas to ensure safe operation.
application scenarios
In the energy industry, especially in power plants, gas turbines, boilers and other equipment may operate at high temperatures, and the shields are used to protect the surrounding components.
Heat protection covers may be required around the engine or exhaust system.
Mechanical manufacturing, industrial furnaces, heat treatment equipment may require a protective cover.
Protection may also be protection around high temperature reaction vessels in the chemical industry.
Protective covers are also used in waste incineration plants or waste heat recovery systems, meeting environmental protection requirements. In addition, the metallurgical industry of the blast furnace steel rolling equipment and other high temperature environment protection is also a potential use.
Heat-resistant steel protective shield is mainly used for the key protection of high-temperature industrial equipment, and its core uses and typical application scenarios are as follows:
1. Heat insulation and protection of high-temperature industrial equipment
Application fields: gas turbine, boiler, industrial furnace, metallurgical equipment, etc.
concrete purpose:
Heat insulation protection: prevent the heat overflow of high temperature equipment (such as power plant gas turbine shell), reduce the ambient temperature, and ensure the safety of personnel and stable operation of equipment.
Mechanical protection: in the metallurgical steel rolling production line or casting equipment, the protective cover can block the molten metal splashing or high temperature dust, to avoid the corrosion or damage of the equipment.
2. Automobile and machinery manufacturing industry
Application fields: engine exhaust system, turbocharger, high-temperature components of industrial machinery.
concrete purpose:
Automotive industry: used for diesel engine exhaust manifold, turbocharger shell, reduce heat transfer to the car body, improve energy efficiency and extend the life of components.
Mechanical manufacturing: install protective cover in the high temperature die area of injection molding machine and die casting machine to prevent thermal deformation and maintain production accuracy.
3. Chemical industry and energy industry
Application fields: petrochemical reactor, oil refinery cracking furnace, biomass power generation equipment.
concrete purpose:
Corrosion protection and sealing: in a high temperature and high pressure reaction environment, protective covers isolate corrosive gases (such as hydrogen sulfide) and protect sensitive instruments and pipes.
Waste heat recovery: in the waste incineration power plant, the protective cover is used for the heat insulation layer of the waste heat boiler to reduce the heat loss and improve the power generation efficiency.
4. Environmental protection and waste disposal
Application fields: waste incinerator, medical waste treatment equipment.
concrete purpose:
High temperature seal: in the feed inlet or grate area of the incinerator, the protective cover to prevent harmful gas leakage, and at the same time to withstand the high temperature in the furnace (up to 1200 C or above).
Corrosion resistance design: for the acid gas produced by waste incineration (such as HCl, SO ₂), the special alloy protective cover is used to extend the service life.
5. Special industrial scenarios
Glass manufacturing: The shields protect the transmission tracks and sensors from high temperature erosion in the molten glass production line.
Aerospace: the insulation layer of rocket engine test bench or high temperature test equipment (Germany has many aerospace technology companies, such as MT Aerospace).m
Typical application enterprise example
1. Energy industry: Gas turbine project of Siemens Energy (Siemens Energy).
2. Automobile manufacturing: the engine production line of Volkswagen (Volkswagen) and Daimler (Daimler).
3. Environmental protection field: EEW Energy from Waste waste incineration plant.
4. Chemical giant: BASF (BASF) high temperature reaction equipment.
