	Introduction
	   Mould taper is an important control parameter in the continuous casting of steel. Properly tapered mould walls compensate for shrinkage of the solidifying strand to maintain good contact and heat transfer between the mould wall and shell surface without exerting extra force on the hot and weak shell. The amount of taper needed varies with steel composition and casting conditions, such as mould length, casting speed, and type of lubrication. Inadequate mould taper leaves an air gap between the mould wall and shell surface which leads to a hotter and thinner shell within the mould. Ferro-static pressure from the liquid core will bulge the weak shell within and out of the mould and even break out the shell in extreme situations. Excessive taper exerts extra load on the solidifying shell and increase dragging friction. Transverse cracks, shell buckling or even shell jamming and breakouts may occur.
	Since 1980’s, Huaxintianzheng Co. Ltd has developed a series of instrument to measure the taper of mould, gap of rolls, to meet the requirement of continuous casting steel production. It makes the measuring work easy and dependable. Now HXTZ can provide complete solutions to all kinds of mould taper measuring requirement for the customer.
