Abstract

FIELD: metallurgical industry, applicable in dross processing in line of hot-dip galvanizing unit. SUBSTANCE: the dross processing furnace in line of continuous hot-dip galvanizing unit has a body separated into two sections by a partition with a branch pipe in the lower part, and the third section located above the second section with a pressure pipe, a vacuum line and a drain branch pipe with a valve are connected to the third section, the first section has a perforated ingot mould and a cover with a heater hinge-joined to the body. EFFECT: improved operating properties of zinc dross processing furnaces.

Description

Изобретение относится к металлургии, а именно к установкам для горячего цинкования стальной полосы. The invention relates to metallurgy, and in particular to installations for hot-dip galvanizing a steel strip.

Известна электропечь для получения цинка, содержащая корпус колпаковой электропечи, муфель, перфорированную изложницу, приемную изложницу. Known electric furnace for zinc, containing a housing bell-shaped electric furnace, a muffle, perforated mold, receiving mold.

Недостатком известной электропечи являются высокие энергетические затраты. A disadvantage of the known electric furnaces are high energy costs.

Задача, на решение которой направлено предлагаемое решение - снижение энергетических затрат, повышение эксплуатационных свойств. The task to which the proposed solution is directed is to reduce energy costs, increase operational properties.

Вышеупомянутый недостаток исключается тем, что в печи агрегата непрерывного горячего цинкования (АНГЦ), включающего ванну для цинкования с расплавом цинка, содержащую корпус со стенками и подом, нагревательные элементы, размещенные в стенках и поде корпуса, и крышку, шарнирно соединенную с корпусом, корпус печи выполнен в виде 2-х секций, разделенных перегородкой с патрубком в нижней части, и герметичной третьей секции, расположенной над второй секцией и соединенной с ней нагнетающей трубкой, при этом к третьей секции присоединен вакуум-провод и сливной патрубок с клапаном. В первой секции имеется перфорированная изложница и шарнирно соединенная крышка с нагревательным элементом. The aforementioned disadvantage is eliminated by the fact that in the furnace of a continuous hot dip galvanizing unit (ANGC), which includes a zinc-plated bath with a zinc melt, comprising a housing with walls and a hearth, heating elements located in the walls and bottom of the housing, and a lid pivotally connected to the housing, the housing the furnace is made in the form of 2 sections, separated by a partition with a pipe in the lower part, and a sealed third section located above the second section and connected by a discharge tube, while a vacuum gadfly and drain pipe with valve. The first section has a perforated mold and a hinged cover with a heating element.

На чертеже показана печь для переработки дросса в линии АНГЦ, общий вид. The drawing shows a furnace for processing dross in the ANGC line, general view.

Печь для переработки дросса в линии АНГЦ содержит корпус 1 печи, разделенный перегородкой 2 с патрубком 3 на секции 4 и 5, при этом к секции 5 присоединена герметичная секция 6 с нагнетательной трубкой 7 и сливным патрубком 8 с клапаном 9 и вакуум-проводом 10, а в секции 4 имеется перфорированная изложница 11, шарнирно соединенная с корпусом крышка 12 с нагревателем. The furnace for processing dross in the ANGC line contains a furnace body 1, separated by a partition 2 with a pipe 3 into sections 4 and 5, while a pressurized section 6 with a discharge pipe 7 and a drain pipe 8 with a valve 9 and a vacuum wire 10 is connected to section 5 and in section 4 there is a perforated mold 11, a cover 12 with a heater pivotally connected to the housing.

Принцип работы печи для переработки дросса в линии АНГЦ следующий. Печь для переработки дросса размещена в ванне цинкования, при этом края секции 4 находятся на уровне расплава цинка. Дросс загружается в перфорированную изложницу 11 и секция 4 закрывается крышкой 12 с нагревателем, расплавленный цинк собирается в секциях 4 и 5, через определенные промежутки времени включается вакуум-насос (на чертеже не показан), в секции 6 создается вакуум и расплавленный цинк из секции 4 и 5 по нагнетательной трубке 7 поступает в секцию 6, при отключении вакуум-насоса открывается клапан 9 и расплавленный цинк поступает в ванну линии АНГЦ. Отходы переработки дросса из изложницы 11 периодически очищаются. The principle of operation of the furnace for processing dross in the ANGC line is as follows. The furnace for processing dross is placed in a galvanizing bath, while the edges of section 4 are at the level of the zinc melt. The throttle is loaded into the perforated mold 11 and section 4 is closed by a lid 12 with a heater, molten zinc is collected in sections 4 and 5, a vacuum pump is switched on at certain intervals (not shown in the drawing), vacuum is created in section 6 and molten zinc from section 4 and 5 through the discharge tube 7 enters section 6, when the vacuum pump is turned off, valve 9 opens and molten zinc enters the bathtub of the ANGC line. Dross processing waste from mold 11 is periodically cleaned.
