The main body of Chinese shipbuilding steel CCS D36 steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main Chinese shipbuilding steel CCS D36 production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
Heat-resistant steel thick plate is made of heat-resistant steel and is processed by hot rolling. According to different structure characteristics, it can be divided into four types: austenitic type, ferrite type, martensite type and precipitation hardening type. Chinese shipbuilding steel CCS D36, The heat-resistant steel plate is widely used in the manufacture of petroleum, chemical equipment, boilers, steam turbines, industrial furnaces and other components and other components working at high temperatures.
When using Chinese shipbuilding steel CCS D36, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.
In the production process of the ironmaking process, the moisture content and air temperature of the ironmaking blast furnace blast have a direct impact on the fuel consumption and fuel consumption structure of the ironmaking process. Blast furnace blast dehumidification is to remove the moisture in the blast furnace blast, eliminate the adverse effects of atmospheric humidity fluctuations on the blast furnace forward movement, and create stable operating conditions for the fans.
Chinese shipbuilding steel CCS D36, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.
