Design on Apparatus for Measurement of Heat Transfer Coefficient in Continuous Casting

This paper analyzes the importance of measuring heat tranfer coefficient in continuous casting in theory and sets out the way to calculate heat transfer coefficient and to design the apparatus. It consists of heating and controlling temperature system. It can amplify and collect the signal system, calcaulate and type the results of system, etc. There is a 8 bit micro-computer and micro-typcr in it.The process,from heating the probe to typing the result, can be done automatically. The measurement was made for many times in same conditions and the results were stable and reliable.
