产品描述

武田机电

捷克VUHZ.A.S是世界最著名的结晶液位传感器制造商,产品广泛地应用于世界各大钢厂,在中国,宝钢,鞍钢,首钢京唐,唐钢,包钢,邯钢,湘钢,涟钢等大中小型钢厂都在使用VUHZ的液位检测产品.

VUHZ产品以其世界上最领先的科技水平,突破了传统的检测系统的局限, 传统的检测系统一般采用Co一60或浮球检测系统。其中Co—60检测虽然精度高,但其具有放射性,需要专业人员保管和使用,安全性不高。而浮球是采用耐材制造的,会受到钢水的侵蚀,需定期人为更换和预热,增加操作人员的劳动强度和中断整个控制系统降低铸机的效率。VUHZ公司电磁感应式传感器,测量范围为0~160mm。VUHZ传感器安装在结晶器的顶部。冷却系统采用直接用铸机的一次冷却水闭环冷却,几乎不用另增设备.

VUHZ结晶液位控制系统包括有VUHZ液位传感器SH7-S10,VUHZ前置放大器SH-P,VUHZ信号处理器SH-E,VUHZ液位传感器电缆,VUHZ信号处理器连接电缆, VUHZ螺栓,VUHZ传感器安装固定底座,VUHZ传感器保护盖板, VUHZ绝缘保护轴套, VUHZ导向垫板, VUHZ绝缘垫片及VUHZ工具.

MOULD LEVEL SIMULATOR H3

Mold level measurement is not sensitive to local meniscus disturbances, such as vortices caused by argon blowing, various types of waves, etc. Sensor's viewing field width is approx. 600 mm and sensor measures mean molten steel level at this section of the mold's width. Typical course of characteristic is shown in.
2.3 Electromagnetic sensor SH7-S10
The sensor has shape of prism. The sensor is made of stainless non-ferromagnetic steel. Two sensing coils are located symmetrically to the axis.
The sensor is fastened to the mold by means of sensor cover, which serves as a clamp and which protects the sensor as well. The sensor cover is screwed on to two special holders fixed to the water jacket – see chapter 4. The cable between sensor and pre-amplifier may consist of two parts. Flexible cable is firmly soldered to each sensor. On the mold top an intermediate connector coupling may be placed, which is connected with pre-amplifier by second part of the cable.

Digital setting-up of the slope, e.g.: 4 mA = 160 mm, 20 mA = 20 mm

VUHZ传感器内部基本结构原理。由励磁线圈S和检测线圈L和检测线圈R组成。励磁采用峰峰值15V频率800HZ的信号。由于浇注时钢液面上有保护渣层,而此励磁产生的电磁信号可以穿透10mm的渣层和18mm钢水。但该电磁信号不能穿透铜板,因此在传感器的其它部位使用铜质的外壳。电磁信号经过钢液面反射回来分别在两个检测线圈上产生与钢液面的高度成相应关系的感应电动势VL和VR。电动势Ve(Ve=VL+VR)和结晶器振动的频率(fo)和振幅(Fo)信号一起作为变送器的输入信号经过补偿、转换成标准的4~20mA液位信号。
