中频电炉在材料入口温度、材料特性、生产线速度等因素的影响下,材料的出口温度的高低取决于控制体系输出功率的大小,功率越大,温度越高,反之亦然,功率决定温度。今天小编为大家州苗木 保定电动门 保定空压机 化粪池模具 微型蠕动泵 保定强夯 收费岛模具介绍的是中频电炉温度控制的注意事项:
Under the influence of factors such as material inlet temperature, material characteristics, and production line speed, the outlet temperature of the medium frequency electric furnace depends on the output power of the control system. The higher the power, the higher the temperature, and vice versa. The power determines the temperature. Today, the editor will introduce the precautions for temperature control of medium frequency electric furnaces:
在实际生产中,各种因素的干扰使得红外线高温计测不准,如被加热材料放射系数的改变、环境光线的影响、加热时产生的烟雾、钢丝的抖动使探头没有对准钢丝中心等。测不准会造成控制体系来回振荡,可以适当延长高温计的采样时间以避免这个问题。
In actual production, the interference of various factors makes the infrared Pyrometer inaccurate, such as the change of the radiation coefficient of the heated material, the influence of ambient light, the smoke generated during heating, and the vibration of the steel wire that makes the probe not aligned with the center of the steel wire. Uncertainty will cause the control system to oscillate back and forth, and the sampling time of the Pyrometer can be appropriately extended to avoid this problem.
材料入口温度的改变会严重影响材料加热后的出口温度,由于拉丝机生产的半成品钢丝的温度直接受冷却条件的影响,冷却效果越差,钢丝残留的热量越多,使得进人中频电炉钢丝的人口温度越高,因此人口温度直接受冷却条件的影响。
The change in material inlet temperature can seriously affect the outlet temperature of the material after heating. As the temperature of the semi-finished steel wire produced by the wire drawing machine is directly affected by the cooling conditions, the worse the cooling effect, the more heat remains in the steel wire, resulting in a higher population temperature entering the medium frequency electric furnace steel wire. Therefore, the population temperature is directly affected by the cooling conditions.
一般而言,半成品钢丝的温度要比气温高些,因此随着存放时间的变化,内外层钢丝的温度会不一样,这样就必须在生产中根据实际情况,适时恰当地修改材料的人口温度。
Generally speaking, the temperature of semi-finished steel wire is higher than the air temperature. Therefore, as the storage time changes, the temperature of the inner and outer layers of steel wire will vary. Therefore, it is necessary to modify the population temperature of the material in a timely and appropriate manner according to the actual situation in production.
