Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

An experimental setup for micro- and macro-studies of specific heat fluxes and thermomechanical properties of refractories has been developed. The influence on the heat resistance of refractory structures of thermal stresses, temperature field, shape and size of products under various heating conditions of their working surface is studied. It is shown that reducing the width of the side of the working surface of the refractory allows you to increase the speed and specific heat flux without violating the integrity of the structure of the refractory material. The distribution of the temperature fields of the refractory with a change in the heating rate of its working surface, as well as its shape, is studied. Ill. 5. Ref. 11.
