Furnace for processing dross in line, continuous hot dip galvanizing

 

Usage: the invention relates to the metallurgical industry and can be used for processing dross in line galvanizing. The essence: a furnace for processing dross in line, continuous hot dip galvanizing includes a housing divided into 2 sections by a partition with a pipe at the bottom and a third section located above the second section of the intake tube, while the third section attached vacuum wire and drain connection with valve, the first section has a perforated mold and cover with the heater connected pivotally to the body. The invention provides improved performance properties furnaces for processing of zinc dross. 1 Il.

The invention relates to metallurgy, and in particular to systems for hot-dip galvanizing steel strip.

Known electric furnace to obtain a zinc containing case Kolpakova furnaces, muffle, a perforated mold, the receiving mold.

A disadvantage of the known furnaces are high energy costs.

The challenge which seeks the proposed solution is to reduce energy costs, increase exploitation the project (plant), including bath for galvanizing with molten zinc, comprising a housing with walls and hearth, heating elements, placed in the walls and floor of the housing, and a lid pivotally connected to the housing, the furnace housing is made in 2 sections separated by a partition with a pipe at the bottom, and sealed the third section located above the second section and connected with it forcing the tube, while the third section attached vacuum wire and drain connection with valve. In the first section has a perforated mold and a hinged cover connected with the heating element.

The drawing shows a furnace for processing dross in line plant, General view.

Furnace for processing dross in-line galvanizing unit includes a housing 1 of the furnace, divided by a partition 2 to the pipe 3 sections 4 and 5, while section 5 is attached sealed section 6 to the discharge tube 7 and the drain pipe 8 with the valve 9 and the vacuum-wire 10, and in section 4 has a perforated mold 11, pivotally connected with the housing cover 12 with the heater.

The principle of operation of the furnace for processing dross in line plant next. Furnace for processing dross placed in the galvanizing bath, the edges of the section 4 are at the level of p is m, the molten metal is collected in sections 4 and 5, after a certain period of time turns on the vacuum pump (not shown), in section 6 creates a vacuum and the molten zinc from sections 4 and 5 of the discharge tube 7 is supplied in section 6, when disconnecting the vacuum pump opens the valve 9 and the molten metal is supplied into the tub line plant. Waste recycling of dross from the mold 11 is periodically cleaned.

Claims
