電力溝蓋板鋼模具的工藝離不開(kāi)熱處置，對(duì)于熱處置冷卻的工序也就非常之重要了，一般退火的冷卻速度最慢，正火的冷卻速度較快，電力溝蓋板鋼模具，淬火的冷卻速度更快。但還因鋼種不同而有不同的要求，例如空硬鋼就可以用正火一樣的冷卻速度進(jìn)行淬硬。加熱溫度是熱處理工藝的重要工藝參數(shù)之一，選擇和控制加熱溫度，保證熱處理質(zhì)量的主要問(wèn)題。保證熱處理質(zhì)量的主要問(wèn)題。加熱溫度隨被處理的金屬資料和熱處理的目的不同而異，但一般都是加熱到相變溫度以上，以獲得高溫組織。電纜溝蓋板鋼模具轉(zhuǎn)變需要一定的時(shí)間，因此當(dāng)金屬工件表面達(dá)到要求的加熱溫度時(shí)，還須在此溫度堅(jiān)持一定時(shí)間，使內(nèi)外溫度一致，電力溝蓋板鋼模具，使顯微組織轉(zhuǎn)變完全，這段時(shí)間稱(chēng)為保溫時(shí)間。它采用高能密度加熱和外表熱處理時(shí)，加熱速度極快，一般就沒(méi)有保溫時(shí)間，而化學(xué)熱處理的保溫時(shí)間往往較長(zhǎng)。更多了解，The process of steel mould for power ditch cover plate is inseparable from heat treatment, which is very important for the cooling process of heat treatment. Generally, the cooling speed of annealing is the slowest, and the cooling speed of normalizing is faster. For steel mould for power ditch cover plate, the cooling speed of quenching is faster. However, there are different requirements due to different steel types. For example, air hardening steel can be hardened at the same cooling rate as normalizing. Heating temperature is one of the important process parameters of heat treatment process. Selecting and controlling heating temperature is the main problem to ensure the quality of heat treatment. Main problems to ensure the quality of heat treatment. The heating temperature varies with the processed metal data and the purpose of heat treatment, but it is generally heated above the phase transformation temperature to obtain high-temperature structure. It takes a certain time to change the steel mold of the cable trench cover plate. Therefore, when the surface of the metal workpiece reaches the required heating temperature, it must be maintained at this temperature for a certain time to make the internal and external temperatures consistent. The steel mold of the power trench cover plate makes the microstructure change completely. This period of time is called the temperature keeping time. When it adopts high-energy density heating and surface heat treatment, the heating speed is very fast, and generally there is no holding time, while the holding time of chemical heat treatment is often longer.
