The article presents the results of an experimental study of the influence of the influence of twisting and bending forces on the terminals of sealed metal-glass products (MSI), leading to depressurization. The critical values ??of the angles of rotation and bending of the leads at which the glass starts to break are indicated. Shown are the technological features of the manufacture of MSI, which increase the strength properties of the metal-to-glass junction.
The results obtained are of interest in the manufacture of various sealed relays and devices, explain the possible reasons for the depressurization of devices.

The understanding of the problems of glass enterprises in the course of cold and hot repairs of glass melting furnaces is reflected. JSC "DINUR" offers assistance and joint cooperation with glass enterprises.
New developments of refractory products have been proposed, including the DSU-1 glass-linas grade, the characteristics of which make it possible to increase the operating life of the furnace. The characteristics of other refractory materials that can be used in various structural units of a glass furnace (vaults, regenerators, suspended walls, an arch of a loading pocket, burner blocks) are considered in detail.

Methods for measuring temperature and gas gradients in batch furnaces of a number of Gzhel enterprises for the production of artistic porcelain are considered. It is noted that the method of mapping furnaces of batch operation applied by the authors makes it possible to determine the gradients of temperatures and gaseous medium in the volume of the furnace cage. In this case, samples of porcelain mass, colored with iron and manganese oxides, temperature control rings were used. For a more uniform temperature distribution in the working zone of the furnace, it is recommended to use ALSITHERM refractory fiber for lining. Bibliography: 3 titles.
