Description
Technical field
The utility model relates to a kind of zinc-aluminium liquid chute heating unit.
Background technology
Aluminium zinc liquid need be incubated processing in the pre-melting pan and the course of conveying between the main zinc pot of hot dip zinc-aluminium unit.The method of using is at present, between pre-melting pan and main zinc pot zinc-aluminium liquid chute is set, and the insulation well heater is installed above this chute; This well heater uses the resistance wire heating, and described resistance wire is arranged on the top of aluminium zinc liquid.
In the use of reality, the resistance wire in the well heater is very easy to damage, and only have only 5～7 days its work-ing life.The reason that the resistance wire of well heater damages mainly contains two aspects: the one, because resistance wire is positioned at aluminium zinc liquid top, is subjected to the corrosion of zinc-aluminium steam easily and damages; The 2nd, the resistance wire in the well heater is in the working order of heating always, and when the temperature of resistance wire was in more than 1350 ℃ for a long time, resistance wire was very easy to damage.And because the electric power incoming line of the resistance wire of well heater adopts the terminal stud mode, it is comparatively difficult to change the resistance wire that damages, and works 1 hour to its functional rehabilitation normal need 4 people from heater failure; If but heater resistance wire is damaged the untimely replacing in back, and the words that put into operation once more, when the aluminium zinc liquid in the chute will solidify after temperature dropped to a certain extent, will cause chute to stop up and damage the anti-material of chute, have a strong impact on the ordinary production of unit.
Summary of the invention
The purpose of this utility model is to provide a kind of zinc-aluminium liquid chute heating unit, and prolong its work-ing life greatly, and can change spare part fast, guarantees the reliable and stable operation of zinc-aluminium liquid chute, does not influence actual production.
For achieving the above object, the utility model provides a kind of zinc-aluminium liquid chute heating unit, and it comprises a well heater, and characteristics are also to comprise protecting sheet and temperature-control heat couple;
Described well heater inside is provided with resistance wire and refractory materials;
Described protecting sheet is installed in the bottom of well heater, the detachable replacing; This protecting sheet is made by silicon carbide;
Described temperature-control heat couple is installed in well heater inside, and the resistance wire of well heater is carried out the limit for height temperature control;
Described refractory materials is made by ceramic fiber, and it is fixedly mounted in the shell of well heater;
Further, also be provided with resistant to elevated temperatures supply lead in the utility model, the one end connects well heater, and the other end is provided with quick plug, and the power-line plug of this well heater can be matchedly connected with the supply lead in the unit housing.
The utlity model has following advantage:
1, corrosion-resistant, the utility model adopts the silicon carbide protecting sheet that aluminium zinc liquid steam and resistance wire are isolated, thereby in heat-processed, can reduce the corrosion of aluminium zinc liquid steam to heater resistance wire, more than work-ing life to 1 of prolongation resistance wire month; Reduce the consumption of resistance wire greatly, reduce production costs.
2, temperature-control heat couple is installed in well heater, resistance wire itself is carried out the limit for height temperature control, temperature is too high damages because of self to prevent resistance wire.
3, well heater and its supply lead adopt the mode of connection of quick plug-in, change rapid and convenient, can shorten the activity duration of maintenance greatly, normally only need 2 people to work from the heater failure to the functional rehabilitation 0.25 hour.Simultaneously, the replacing of the resistance wire of well heater can be carried out by off-line, does not influence ordinary production; Can solve zinc-aluminium liquid thus and damage because of heater resistance wire and cause temperature to descend solidifying and stop up the problem of chute, obviously reduce the number of times of the shutdown that unit caused because of the chute fault.
Description of drawings
The structural representation of the zinc-aluminium liquid chute heating unit that Fig. 1 provides for the utility model.
Embodiment
Following according to Fig. 1, a kind of preferred forms of the present utility model is described.
As shown in Figure 1, the structural representation of the zinc-aluminium liquid chute heating unit that provides for the utility model, it comprises a well heater 101, also comprises protecting sheet 102 and temperature-control heat couple 103;
Described well heater 101 inside are provided with resistance wire 1011 and refractory materials 1012;
Described protecting sheet 102 is installed in the bottom of well heater 101, the detachable replacing; This protecting sheet 102 is made by silicon carbide, can prevent the corrosion of zinc-aluminium liquid steam to resistance wire 1011;
Described temperature-control heat couple 103 is installed in well heater 101 inside, and the resistance wire 1011 of well heater is carried out the limit for height temperature control; When the temperature that records resistance wire 1011 when temperature-control heat couple 103 surpasses 1000 ℃, cut off the working power of resistance wire 1011, do not damage because of ultrahigh-temperature with protective resistance silk 1011; When the temperature that records resistance wire 1011 when temperature-control heat couple 103 was lower than 1000 ℃, the working power of closed resistance silk 1011 needed with the heating that guarantees the aluminium zinc liquid in 101 pairs of zinc-aluminium liquid of the well heater chute again;
