Description

(li-l) ilAKLT DED RECEIVING MULTILAYER SHEETS

one

The invention relates to the field of ferrous metallurgy, mainly for the production of double-layer sheets.

A package for producing multi-layer sheets is known, consisting of blanks of the base and cladding layers, connected by a sealing frame arranged with a gap relative to the cladding layer L.

The main disadvantage is the packet rupture in the gshastic deformation process.

The purpose of the invention is to prevent the package from breaking during plastic deformation.

This goal is achieved in that the frame is provided with clamps located along its perimeter in the gap between the frame to the cladding layer, with the height of the clamps being 0.026-0.027 package length and 0.0290,030 of the package width.

The drawing shows a bag for multi-layer sheets.

The package consists of the blank 1 of the cladding layer, the blank 2 of the main layer, the sealing frame 3 and the fixer 4 with a height of 0.025-0.027 package length and 0.029-0.030 width

it is located around the perimeter, whereby the blanks of the cladding layer are arranged in relation to the frame with a gap, taking into account the difference in the coefficients of linear expansion and the resistance to deformation and the cut flatness.

Fixing blanks cladding layer in the package prevents moving them during transport, which

0 reduces the likelihood of destruction of the release coating and the nickel coating, and also provides a predetermined gap between the frame and the workpieces. Example. A four-layer package consisting of two slabs of 16GS steel with dimensions 110/100 x 1200 1500 (numerator upper slab, denominator - lower) is made between two plates with a height of 22 x 1080 x 1330 made of 08X13 steel, sealing frames from a strip 40 mm wide and 49 mm high, and four clamps located along the perimeter, the size of the clamps

5 on the longitudinal side of 40 mm, on the transverse 35 mm. The bag is heated in a three-zone furnace and rolled according to the usual rolling pattern. Package rolling occurs without
