Abstract: FIELD: working of metals. 
     SUBSTANCE: invention relates to the processing of metals by pressure and can be used in deformation of tubular and rod-like products. Preliminarily, a load is applied to the rectilinear samples installed in supports at a given speed by means of a punch. The dependence of the residual deflection of the sample on the distance between the supports and the value of applied load, the maximum permissible load causing no plastic deformation of the cross-section of the sample, and the speed of application of the maximum permissible load are determined. The deflection of the product placed on the base surface in the deflection plane in the section with the greatest deflection and the size of the load base are determined. The section of the product with the greatest deflection, when placed on the supports set at the borders of the load base, is deformed with a reverse deflection at a speed determined on the sample at the maximum permissible load. The deflection and the size of the load base of all remaining curvilinear sections in the deflection planes are determined and said sections are deformed on the load base with reverse deflection. 
     EFFECT: required rectilinear shape of the product is obtained as a result while maintaining the shape of the cross-section thereof.

The foam stabilizer is one or more of modified polyethoxylated silicone (MPS), triethanolamine (TEA), diethanolamine (DEA), cocoalkyldimethyl betaine, and polyethylene glycol (PEG). To obtain the aforementioned gel, water glass is mixed with deionized water. Bring the mass concentration of liquid glass to 4%-35%. Mix uniformly until a mixed solution is obtained. At the second stage, the foaming agent, foam stabilizer and coagulant are successively added to the mixed solution and mechanical stirring at a speed of more than 1000 rpm until the final formation of a foamed gel. The aforementioned gel is used to feed into the mined-out space of a mine to combat spontaneous combustion of coal. The foamed gel obtained by mixing and foaming water glass, foaming agent, foam stabilizer and coagulant is fed into the goaf. It covers the surface of the coal mass, forming a foam layer that cools the mass and blocks oxygen. 
     EFFECT: increased efficiency of the fire-fighting effect without subsequent smoldering by slowing down the combustion rate, lowering the temperature of the combustion source, heat release and the formation of CO.
