Description
С целью повышени тем пературы чугуна, выпускаемого из ваграчки , обычно прибегают к дуплекс-процессу, при котором чугун подогревают в электропечи.In order to increase the temperature of the cast iron produced from the furnace, it is usual to resort to a duplex process in which the iron is heated in an electric furnace.
Предлагаемый способ подогрева чугуна электрическим током непосредственно на выпускном желобе при выпуске чугуна из вагранки исключает применение громоздкой установки дуплекс-процесса.The proposed method of heating cast iron by electric current directly on the discharge chute when cast iron is released from the cupola eliminates the use of a cumbersome installation of a duplex process.
Дл осуществленн способа подогрева чугуна непосредственно на выпуске Б футеровку выпускного желоба помещают два угольно-графитных электрода 1 к 2 (см. чертеж), из которых один - / заделывают в футеровку в переднем конце желоба, а другой - 2 в заднем конце желоба, около выпускного очка вагранки. Электроды 1 и 2 служат контактами, к которым подключают электрический ток, замыкаемый струей текущего чугуна.For the method of heating the cast iron directly on release B, the lining of the discharge chute is placed by two carbon-graphite electrodes 1 to 2 (see drawing), one of which is / is embedded in the lining at the front end of the chute, and the other is 2 cupola discharge point. Electrodes 1 and 2 serve as contacts, to which an electric current is connected, which is closed by a stream of current cast iron.
Электроды 1 к 2 изолированы от корпуса кожуха желоба вагранки электроизол ционной прокладкой (миканит, асбест) и прочно соединены с медными шинами, подведенными в нижнюю часть желоба через соответствующие окна под каждым электродом / и 5. Медные шины имеют каналы вод ного охлаждени .The electrodes 1 to 2 are insulated from the casing of the cupola chute by an electrically insulating gasket (micanite, asbestos) and are firmly connected to the copper tires led to the bottom of the chute through the corresponding windows under each electrode / and 5. The copper busbars have water cooling channels.
Угольно-графитные электроды должны прочно соедин тьс с медными шинами дл обеспечени надежного контакта.Carbon-graphite electrodes must be firmly connected to the copper busbars to ensure reliable contact.
Силовой трансформатор 3 располагают возможно ближе к желобу, а всю электроан11аратуру управлени размещают на щите управлени около вагранки.The power transformer 3 is located as close as possible to the chute, and the entire electrical control is placed on the control board near the cupola.
Указанный способ нагрева чугуна на желобе при его выпуске из вагранки обладает высокой маневренностью, дава возможность варьировать температуру подогрева чугуна в широких пределах, допускаемых мощностью трансформатора.This method of heating the cast iron on the gutter when it is released from the cupola has high maneuverability, making it possible to vary the heating temperature of the cast iron within the wide limits allowed by the transformer power.

Дл обеспечени равномерности сечени струи жидкого чугуна, стекающей по желобу, радиус футеровки желоба делают равным 3 см вдоль. всего желоба,To ensure a uniform cross-section of the jet of liquid iron flowing down the chute, the radius of the lining of the chute is made equal to 3 cm along. total gutter
