    A method of producing a clad shaped body by roll-bond cladding of a sandwich-like cladding package closed on all sides, which is evacuated before being heated to rolling temperature employs a metallic intermediate layer comprised of a pure iron sheet provided between the base material comprised of steel and the cladding material comprised of titanium.

    1. The invention relates to a method for the manufacture of clad billets by rolling a multilayer closed bag in which there is a metallic intermediate layer between the steel base and the cladding: titanium substrate. A known method of making a clad billet is made by assembling a package from a base material and a titanium substrate, pumping heating air to the deformation temperature and rolling deformation. The disadvantage of the method is the low quality of the compound due to the formation of fragile metal compounds at its boundary. The purpose of the invention is to increase the penetrability of the compound by preventing the formation of brittle metallic compounds. The goal is achieved by the fact that before assembling the package, the substrate, at least from the side facing the base material, is covered with technically pure iron, and then air is pumped out at 1-10-150 ° C, and the deformation occurs at 650 750С. The application of technically pure iron to the substrate is carried out in a galvanic bath. Technically pure iron is deposited on the substrate from all lines. Kra go | and before coating it with technically pure iron, a wedge-shaped form is performed. After deformation on the outer side of the substrate, the layer of technically pure iron is removed. Approx. 1. On the base material, which is used as boiler sheet steel,. It is necessary to overlap titanium sheet. In order to form a multilayered plating bag, two slabs of steel with a size of 2000 x 1100 x X210 mm and two titanium sheets with a size of 1900 x 1000 x 30 mm are taken. Before assembly into the package, titanium sheets are electrolytically coated with technically pure iron with a shell thickness of 2. mm. A plating bag made of slabs and sheets subjected to pretreatment in the electrolyte, in which titanium sheets are occupied with an intermediate position between the base material, tightly welded with a perimeter (extrusion method). After unloading the package with a temperature of 110ISO C in a vacuum with a vacuum of 10 mm Hg. it is heated to 720 ° C. Hot rolling occurs at 720-680 ° C. The dimensions of the finished board 5220) 4200 mm. After opening the bag, the two clad sheets are 21 + 3 mm thick each. Of them make arched hearth boxes. For this, circles with a diameter of 3700 mm are cut out, which are heated for a short time before and then arched hearths of boxes with a section of 3000 mm are pressed from them. At the end, the surface of the substrate, protected by a layer of technically iron, is deciphered. Example 2. A titanium substrate is superimposed on the boiler sheet. After that, two titanium sheets of 2000 X 20 mm in size on both sides are clad with the method of explosive cladding with a layer of technically pure iron 2 mm thick. The edges of the cladding substrate are wedge-shaped so that pure iron-plating covers the substrate from all sides. Technically pure iron contains a maximum of 0.006% carbon. The dimensions of the ingot from the base material 2100X 1500X 150 mm. From titanium sheets with an iron sheath and ingots of the base material, a bag is assembled in the usual way, which is welded around the perimeter with a dense weld, and welding is performed under pressure from the press so that the number of honestly penetrating the air bag is minimal. and discharged, the vacuum under vacuum being 1 (H mmHg. Unloading the bag clad with the rolling method takes place at 110-150 ° C. The bag is then heated to 680-720 ° C and rolled on rollers, forming a slab of size 11400X 27805 34 ,four After separation of the package, two sheets clad with titanium have a thickness of 15 + 2.2 mm, and the surface of the titanium substrate is covered with a layer of technically pure iron with a thickness of 0.2 mm. The finished sheet has dimensions of 10,000 l 2500 x X 15 + 2 mm, significantly larger than the size of titanium-clad sheets.
