预热与加热
Preheating and heating
无变压器铁芯磁感应加热比功率小,一般选用无变压器铁芯高传感器加热淬火的热轧带钢*好是经炉中总体预热,其预热溫度应以追求完美做到硬底化层深层为总体目标决策,还应依据热轧带钢尺寸、传感器输出功率、是不是內外制冷以及淬火后是不是开展冷暴力为总体目标决策,预热溫度一般≥500~560℃为好。热轧带钢加热溫度适度提升30-45℃和马氏体化時间为8-15min来提升热轧带钢淬火的硬底化层深层。
The magnetic induction heating of non transformer iron core is smaller than power. Generally, the hot-rolled strip with high sensor of non transformer iron core is selected for heating and quenching. The best way is to preheat the strip in the furnace. The preheat temperature should be determined based on the overall goal of pursuing perfection and achieving the deep layer of hard bottom layer, and should also be determined according to the size of hot-rolled strip, output power of the sensor, temperature and temperature The overall goal of decision-making is whether the internal and external refrigeration and whether the cold force is carried out after quenching, and the preheating temperature is generally better than or equal to 500 ~ 560 ℃. In order to improve the deep hardening layer of hot-rolled strip, the heating temperature of hot-rolled strip is increased by 30-45 ℃ and the martensitization time is 8-15min.
洒水淬火
hardening by sprinkling
无变压器铁芯高传感器对热轧带钢开展磁感应加热淬火,因加热深层深,务必选用大水流量洒水淬火,必需时还需依靠管理中心孔开展大水流量的內外制冷,以获得高硬、超挖、地应力情况*好的高品质热轧带钢。选用大喷嘴、大水流量、低压力、多层面恒定的新式喷水嘴,并增加气体绝热变形致冷的制冷设备。
The magnetic induction quenching of hot rolled strip is carried out by the high sensor without transformer core. Because the heating depth is deep, it is necessary to select the high water flow sprinkling quenching. If necessary, it is also necessary to rely on the management center hole to carry out the internal and external cooling of high water flow, so as to obtain high-quality hot rolled strip with high hardness, over excavation and good in-situ stress. A new type of water spray nozzle with large nozzle, large water flow, low pressure and constant multi-layer surface is selected, and the refrigeration equipment with gas adiabatic deformation refrigeration is added.

淬火附设设备和测温仪器
Quenching equipment and temperature measuring instrument
要选用无变压器铁芯高传感器对热轧带钢加热淬火务必要有相对的附设设备,包含1)变压稳压管设备以保证工作电压输出功率的调节和工作电压的平稳。
In order to select the transformer free iron core high sensor to heat and quench the hot rolled strip, it is necessary to have relative attached equipment, including 1) voltage transformer and voltage stabilizing tube equipment, so as to ensure the regulation of working voltage output power and the stability of working voltage.
确保有充足大水流量的洒水淬火系统软件和低压力,大水流量的喷水嘴。此外,与全部磁感应加热一样,热轧带钢在磁感应加热淬火中应该有精确的测温仪器,电子光学高温计温度测量差值很大,可挑选英国IRCON企业红外线测温仪或中国高精密磁感应加热红外线测温仪、SMT温度控制追踪议等。
Ensure that there is sufficient water flow of sprinkler quenching system software and low pressure, high flow of water nozzle. In addition, as with all magnetic induction heating, there should be accurate temperature measuring instruments for hot rolled strip during magnetic induction heating quenching. The temperature measurement difference of electronic optical pyrometer is very large. You can choose infrared thermometer of British ircon enterprise or high precision infrared thermometer of Chinese magnetic induction heating, SMT temperature control tracking proposal, etc.
冷暴力
emotional abuse
要获高硬、超挖的高品质热轧带钢,经无变压器铁芯高传感器加热淬大后务必开展冷暴力,要有能开展-120℃冷暴力,以调节热轧带钢因淬火后的残留马氏体量,保证热轧带钢有高硬、较深的NM500耐磨板淬火硬底化层和*好地应力情况。
In order to obtain high-quality hot-rolled strip with high hardness and overbreak, it is necessary to carry out cold force after being heated and quenched by high sensor of transformer free iron core. It is necessary to carry out cold force at - 120 ℃ to adjust the amount of residual martensite of hot-rolled strip after quenching, so as to ensure that the hot-rolled strip has high hardness, deep quenched hard bottom layer of nm500 wear-resistant plate and good in-situ stress.
