在運行時，鍋爐板受到鍋內(nèi)水與蒸汽的壓力作用，同時又受到火焰或煙氣的烘烤或沖刷，以及鍋水和煙氣中有害物質(zhì)對鋼材的腐蝕，其工作條件惡劣。
At run time, boiler plate pressure exerted by the water and steam, but also by flame or smoke baking or flushing, and boiler water in flue gas and harmful substances on the corrosion of steel, its working condition is bad.
其中主要是通過在整個生產(chǎn)過程中的工藝控制使最后得到的產(chǎn)品具有良好的焊接及冷彎性能、一定的高溫強度和耐堿性腐蝕、耐氧化等。因此對鍋爐鋼的性能要求比較嚴格，要同時擁有多種優(yōu)良工藝性能和良好質(zhì)價比以保證機組安全可靠運行。
Which is mainly through the entire production process control so that the resulting product has good welding and bending performance and a high temperature strength and alkali resistance, corrosion resistance and oxidation etc.. Therefore, the boiler steel performance requirements are more stringent, at the same time to have a variety of excellent technical performance and good quality to price ratio to ensure the safe and reliable operation of the unit.
由于鍋爐鋼板處于中溫高壓狀態(tài)下工作，除承受較高壓力外，還受到?jīng)_擊，疲勞載荷及水和氣的腐蝕，因此對鍋爐鋼材的性能要求比較嚴格。
Because the boiler plate is working under the condition of high temperature and high pressure, in addition to bear high pressure, but also by the impact, fatigue load and water and gas corrosion, so the boiler steel performance requirements are more stringent.
通常鍋爐使用的是中厚板，其材料有平爐冶煉的低碳鎮(zhèn)靜鋼或電爐冶煉的低碳鋼，含碳量Wc在0.16%-0.26%范圍內(nèi)。制造高壓鍋爐時則應用珠光體耐熱鋼或奧氏體耐熱鋼。
Usually use the boiler plate, the material has low carbon steel low carbon steel smelting furnace or electric furnace smelting, the carbon content in the range of 0.16%-0.26% Wc. Application of pearlitic heat-resistant steel or austenitic heat-resistant steel when manufacturing high pressure boiler.

Q245R鍋爐板軋制工藝的制定和技術措施上，充分結(jié)合煉鋼廠鑄機臺數(shù)多，坯料規(guī)格多，可靈活進行組坯軋制的特點，在滿足壓縮比的條件下，實現(xiàn)了軋制道次的優(yōu)化，減少了控軋時間對產(chǎn)量影響的不利條件，合理的制定了既能確保鋼板性能要求，又不影響軋機能力發(fā)揮的坯料配置。
The formulation and technical measures of Q245R boiler plate rolling process, fully integrated steel plant casting machines, material specifications, flexible features of group billet rolling, to meet the compression ratio, realize the optimization of rolling times, reduce the time of controlled rolling and unfavorable conditions for yield, reasonable the formulation ensures that the steel performance requirements, and does not affect the ability to play the rolling stock configuration.
