(54) REGENERATIVE UNIT FOR PATENTING

WIRES

i

This invention relates to heat treating a wire.

Of the limestones for wire patenting, the closest to the technical essence is the installation containing unwinding and winding devices, rollers, isothermal holding bath and heating furnace with inlet and outlet openings l.

The disadvantage of the unit is that due to the oncoming movement of the wire in an isothermal holding bath, in the latter, without any additional devices, it is impossible to achieve a single, close to isothermal, temperature of the melt. And this leads to a reduced quality of the patented wire.

The counter-movement of the wire from the unwinding device to the winding device (x) and the installation of additional immersion devices in an isothermal holding bath create great difficulties in maintaining the unit.

The purpose of the invention is to reduce the production area occupied by the unit. .

This is achieved by the fact that the heating furnace is installed above the isothermal holding bath and is filled with filling channels, positioned and under the hearth.

FIG. 1 shows a patenting unit for steel wire; on fig. 2 - section aa and n of fig. J ..

The unit consists of a bath 1 of isothermal heating with melt, for example sodium nitrate, a heating furnace 2 located above the bath, a system of immersing 3, 4 and bypass 5, 6 rollers as well as unwinding and winding devices located on opposite ends of the unit (in the drawing shown).

The unit works as follows.

The cold wire 7 comes from the unwinding device to the watering roller 5 located above the molten bath 1 in front of the furnace 2 above the height of a person for ease of maintenance, and then next to the immersion rollers 3 and 4. In the area between the immersion rollers 3 and 4 of the wire, when heated, select part of the heat from the molten bath and heated to a temperature of about 450 ° C. steps into the furnace 2. The wire is pushed through the bath manually through the filling channels 8 located below the furnace 2 and above the melt 1, which causes no difficulties. In the furnace, the wire is heated to a predetermined process temperature of about 92 ° C. The wire is heated from the furnace through the immersion roller 3 enters the isothermal holding bath 1 again, gives off the melt of the bath at the entry point of the cold wire more intensively (which achieves a uniform temperature and melt temperature), keeps the thermal core in the melt and through the immersion roller 4 and bypass 6 is supplied to the remotest processing and to the winding device. The unit for the patenting of the design wire is easy and easy to implement. gives apachellosho to reduce the area occupied by them, thanks to

Claims (1)

Fyg, 1 placing the stove above the isothermal holding bath. The movement of the wire in a closed loop at the bath-furnace site allows fuel to be used more economically due to the regeneration of the heat of the heated wire in the bath melt and does not require maintenance. Formula for the use of the regenerative unit for the patent: - wire spinning, - containing unwinding and winding devices, rollers, isothermal holding bath and heating furnace with inlet and outlet openings, in order to reduce the production area occupied by the unit, the heating furnace is installed above the isothermal bath and is made with filling channels located under the floor.
