Description

The invention relates to a method for producing a heating floor which is used in particular for brewery installations.

The known heating bottom consists of a copper bottom and a steel strand of the duplicator and is made of spherical parts between which a heating space is formed. Straight copper plates for the bottom are cut into specified shapes and welded together) welds are forged and grinded. The weld is then shaped by tapping into the shape of a partial anulold and a spherical segment. At the same time, a duplicate beach is made in a similar way from the oak skin · Copper bottom and the steel beach of the duplicator rivet to each other, creating a single oel with an internal space between the two parts ·

Other «mother heating bottom is ooel and is made in the form of a conical duplicator · The bottom is welded from shaped stainless steel bales and shaped into a truncated cone · In the same way the beach of the duplicator is made in the same cone Then the bottom and the beach of the duplicator cling to each other and weld to each other at the edges and in the squeeze.

Spherical shaping is prone and consuming of heavy metals. Also, the process of making an oily heating floor is difficult and time consuming, in particular making extrusions on the beach of the duplicator, aligning the bottom with the jacket and making strength and sealing welds.

It therefore proposes a new method for producing a heating bottom, in particular a brewery bottom. The essence of the method is that the bottom and the jacket of the duplicator are formed into two gsometriques of the same shape, for example truncated cones, whereupon the bottom and jacket are welded together. continuous weld, welded intermittently in the area and subjected to a hydraulic overpressure predetermined such that by exceeding the yield point a permanent defoxmaoe occurs between the bottom and the jacket of the duplicator ·

This method of manufacture is less laborious and therefore more economical. The heating floor produced in this way is of the same quality as the bottom produced in a known manner *

For the production of the heating floor, it is possible to proceed as follows:

First, the seams are welded straight to the required area · Then a part of the developed truncated cone is burned on the firing machine · the parts are twisted, rolled together in a cylindrical cylinder and welded to each other in the truncated cone shape. Both truncated cones must be identical · Then the bottom and the jacket of the duplicator are placed on top of each other and connected to each other on the bottom and top base by a continuous weld · Then the truncated cone jacket of bottom and jacket of the duplicator is joined by spot welds with 250 mm pitch. Pressurized liquid is introduced through the throat between the bottom and the jacket of the duplicator. · By increasing the hydraulic overpressure by design, the yield limit is exceeded. thus creating a chamber space between the parts, a chock-shaped arrangement as the individual spot welds are located ·

If the distance between the bottom and the jacket of the duplicator reaches 25 mm in the individual space, the pressurization is terminated. Because the compression limit exceeds the elongation limit, a permanent defoxmaoe occurs for both parts materials so the chamber space remains permanent.
