CONTROL OVER COOLING OF SLAB ON BASIS OF EFFECT OF REPEAT HEATING OF ITS SURFACE

There the purpose is to develop the theory of repeat heating of slab surface in the zone of repeat cooling, the methods and the manners to control the cooling of slab. The interconnection of thermal characteristics of pouring and the temperature state of equipment has been ascertained. The new manner of continuous determination of thickness of metal shell has been developed on the basis of use of effect of repeat heating of slab. The new manner of continuous measurement of temperature of slab surface and of prediction of quality of metal surface on this basis has been developed. The calibration method of system of repeat cooling of metal has been developed. The feasibility study for the overhaul of system of automatic regime has been presented. The means of continuous control of metal temperature have been developed. The means of continuous control of thermal conditions of slab have been introduced. The calibration method of system of repeat cooling, the engineering methods to determine the varibles of water cooling, the prediction methods of quality of slab surface according to the magnitude of its temperature have been accepted for introductionAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

Computational experiment on determination of load on the rollers of continuous casting machine

The article is devoted to calculations of load on rollers of a curvilinear continuous casting machine during bending of the ingot in the levelling section. The calculation takes into account the elastic and plastic characteristics of metal and the flexibility of the roller apparatus. Determination of load on rollers together with meeting other requirements such as reducing the cooling water consumption, minimizing the energy consumption enables optimizing the technology of slab cooling in the secondary cooling zone (SCZ) and obtaining metal of the required quality.</jats:p
