Definitions
- the present invention relates to a device and a method using this device for the purpose of coating of steel sheets by immersion in a liquid metal according to which the sheets pass through, so continues, an annealing oven and descend into the bath liquid metal through a metallic sheath extending between the oven and the bath and whose lower end plunges into the bath.
- intermetals in question have a size ranging from 2 to 50 microns and are made up of iron and alloy metals. These are in particular the delta phase (FeZn) and Fe 2 Al 5-x Zn x in galvanization, Fe 5 Al 20 Si 2 in aluzinc, Fe 2 Al 9 Si 2 in an aluminized galvanization bath with silicon and FeAl 3 in Galfan®.
- delta phase FeZn
- Fe 2 Al 5-x Zn x in galvanization Fe 5 Al 20 Si 2 in aluzinc
- Fe 2 Al 9 Si 2 in an aluminized galvanization bath with silicon and FeAl 3 in Galfan®.
- the required heating power is important, as well as the electrical consumption.
- the object of the present invention is to provide a new method and device for reducing substantially the formation of the aforementioned defects.
- the device proposed by the invention is that of claim 1 appended. Claims 2, 3 and 4 describe preferred embodiments of this device.
- the invention also relates to a method comprising the use of such devices, according to claims 5 and 6 appended.
- the invention is based on observations and measures relating to the formation of these faults and essentially consists in eliminating parameters and conditions favorable to the formation of defaults.
- the sheath Under normal industrial conditions, the sheath is subject to variations in thermal regimes as a result of inevitable variations in the level of bath surface, either by waves or by adding fresh metal (liquid or solid).
- the line of anchorage When, the line of anchorage is displaced, for example following a rise in the bath level, the temperature profile at this point is amended. In particular, cooler areas can be brought back to bath temperature. He was noticed that these conditions are favorable for dropping out of previously crystallized particles.
- the mechanism exact chemical is not known but could, for example, result from a partial solution or a transformation of the chemical composition. If, moreover, the particle thus detached is of lower density than the bath, it floats and can be attracted, trained and fixed on the sheet scrolling in its vicinity and thus create the appearance defects.
- a strip of sheet metal from from an annealing oven enters a liquid metal bath to undergo a coating, for example by galvanization. Between the oven and the bath, the sheet goes through a closed sheath which plunges into the metal bath.
- the sheath comprises, at least in the part which plunges into the bath, a double wall between which finds a heating system, for example resistors electrics placed under the control of a regulation including a skin temperature measurement, by example a thermocouple.
- a heating system for example resistors electrics placed under the control of a regulation including a skin temperature measurement, by example a thermocouple.
- the resistors and the regulation system are designed to ensure, permanently, in the included area between 3 cm above and 3 cm below the bath level and in particular at the level of the mooring line, a skin temperature inside the sheath which is located in the range between t - 30 ° C and t + 50 ° C, t being the temperature of the metal bath.
- Heating and thermal insulation of the sheath can advantageously complement each other without their association is compulsory, thermal insulation can be made with conventional insulators or with coatings ceramics.
