The results of a petrographic study of the pore structure of chamotte filler, a binder of aluminosilicate refractory concretes and rammed chamotte bar are presented. It has been established that basically the porous structure of vibrocast aluminosilicate concretes produced by the Semiluki Refractory Plant is represented by closed round pores. Il. 6, bibliography: 5 titles.

JSC "Borovichi Refractory Plant" has developed and mastered the production of a number of new types of refractory products for the construction and repair of glass furnaces: shaped cup-type packing for regenerators of glass furnaces (chamotte, mullite-corundum and periclase-spinel compositions); fireclay lightweight with a density of 0.9, 1.0 and 1.3 g / cm3, having increased strength; large-block products for laying the bottom of glass furnaces; elements of the topside, working channels, burners and other elements of the glass-melting furnace (according to the customer's drawings) made of low-cement concrete. The products have an increased technical resource and have proven themselves well when used in a number of glass factories. Tab. 7, ill. 1, bibliography: 7 titles.

Semiluki Refractory Plant produces refractories using concrete technology and develops and improves compositions and technology for manufacturing large-sized products by vibrocasting. The Saratov Institute of Glass carried out operational tests of concrete samples and determination of their physical and mechanical characteristics. Tests of specimens fired at a temperature not exceeding 1000 ° C showed a sufficiently high compressive strength (from 40 to 60 N / mm
2 ). Tab. 1, ill. 1, bibliography: 4 titles.

To prevent glass defects formed from the lining that breaks down during operation, and to maintain the operable state of the float bath equipment, it is necessary to use high-quality refractory materials, developed taking into account the peculiarities of their service. At the Saratov Institute of Glass, the maximum permissible parameters of fluctuations in the composition of the gaseous medium in the melt bath, causing the destruction of the refractory lining, have been determined. Tests were carried out under operational conditions of new types of composite materials - concretes on a fireclay refractory base, manufactured at the Semiluki Refractory Plant. Tab. 1, ill. 1, bibliography: 3 titles.
