Abstract

1495579 Metallurgical units NL INDUSTRIES Inc 29 July 1975 [12 Aug 1974] 31790/75 Addition to 1483613 Heading B3H A metallurgical unit comprises a stack of toroidal metal briquettes as described in Specification 1,483,613, the briquettes being held positioned to have apertures therein in alignment. The briquette (20), Fig. 2 (not shown), is a body of ferrous metal impregnated with magnesium metal and has a central aperture (24). The stack is placed in a container (21) having end closures (22) provided with apertures aligned with the apertures (24) and sealed by covers (23) which also fit into the apertures (24) of the outermost briquettes to hold the stack in alignment. In an alternative form, the briquettes 51 are located on a rod 52 between holding pins 53, the assembly being placed in a container 54. The rod protrudes through a top end closure 55 and ceramic cement 57 seals the opening around the rod. In a further embodiment a rod (42), Fig. 4 (not shown), passes through both ends of a container (41), in which are located briquettes (40), and the container assembly is held on the rod by pins (43). The briquettes may be removed from the container prior to immersion in molten iron or the container, which is of steel, may also be immersed in the melt. 0À65 lb. of Mg. is added to each ton of molten iron and a rapid reaction lasting four minutes follows. After eight minutes the briquettes and rod and the metal container, if present, are also dissolved. The rod is preferably of ceramic coated steel or all ceramic.

Description

(54) БЛОК РЕАГЕНТОВ(54) REAGENT BLOCK

1one

Насто щее изобретение относитс  к металлургии черных металлов, конкретнее к обработке чугуна металлическими брикетами насыщенными магнием.The present invention relates to the metallurgy of ferrous metals, more specifically to the processing of cast iron with metal briquettes saturated with magnesium.

Известны блоки реагентов, состо щие из дисков или металлических брикетов, насыщенных магнием и собранных в пакет .Reagent blocks are known, consisting of disks or metal briquettes saturated with magnesium and assembled into a bag.

Однако, их применение дл  обработки чугуна сложно, требует специальных устройств дл  погружени  бриктов в металл.However, their use for the treatment of cast iron is difficult, and requires special devices for immersing bricks in the metal.

Целью изобретени   вл етс  упрощение процесса обработки металлического расплава реагентам и.The aim of the invention is to simplify the process of processing molten metal reagents and.

Дл  достижени  поставленной цели, блок реагентов снабжен контейнером со стержнем , проход щим по его оси, причем блок реагентов установлен внутри контейнера и зафиксирован относительно него , проход щим через отверсти  по оси дисков или брикетов, и пальцем-фиксатором, введенным .в стержень под дисками или брикетами .To achieve this goal, the reagent unit is provided with a container with a rod passing along its axis, the reagent unit being installed inside the container and fixed relative to it, passing through the holes along the axis of the disks or briquettes, and with the latch finger inserted into the rod under the disks or briquettes.

На фиг. 1 изображен кольцеобразный брикет из железного скрапа, насыщенного металлическим магнием; на фиг. 2 - вертикальный разрез брикетов, вставленных вFIG. 1 shows an annular briquette of iron scrap, saturated with metallic magnesium; in fig. 2 is a vertical section of the briquettes inserted into

. контейнер; на фиг. 3 - стержень с детал ми дл  удержани  блока; на фиг. 4 - вертикальный разрез бриктов, вставленных в , контейнер со стержнем; на фиг. 5 - вертикальный разрез другой формы блока реаген5 тов.. container; in fig. 3 — rod with parts for holding the unit; in fig. 4 is a vertical section of the brikts inserted in the container with the rod; in fig. 5 is a vertical section of another form of the reagent block.

Металлический кольцеобразный брикет 1, изготовленный из спрессдванного пористого скрапа, насыщенного металлическим магнием, с отверстием 2 по центру собираетс  в пакет брикетов, который установлен 10 в контейнере 3 с концевыми стенками 4, имеющими ценУральные отверсти  5, которые закрываютс  плотно пригнанными крышками 6. Отверсти  2 в кольцеобразных брикетах соосны с отверсти ми 5 в концевых стенках контейнера 3. Стержень 7 пропускаетс  A metal ring-shaped briquette 1 made of pressed porous scrap saturated with metallic magnesium with a hole 2 in the center is assembled into a briquette bag which is installed 10 in container 3 with end walls 4 having central holes 5 which are closed tightly fitted with lids 6. Holes 2 in ring-shaped briquettes coaxially with holes 5 in the end walls of the container 3. The rod 7 is passed

15 через пакет и пальцы-фиксаторы 8 дл  удержани  пакета на стержне.15 through the bag and pins 8 to hold the bag on the rod.

Кольцеобразные брикеты 1 установлены в контейнере 3. Пакет монтируетс  на стержне 7 и удерживаетс  на нем пальцами-фикса20 торами 8.Ring-shaped briquettes 1 are installed in the container 3. The package is mounted on the rod 7 and held onto it by fingers-fixers 8.

Пакет другой формы (фиг. 5) собирает . с  из кольцеобразных, брикетов 1, предварительно помещенных на стержне 7, и удерживаетс  в определенном положении пальцами-фиксаторами 8. Предварительно собранные брШеты и стержень устанавливаютс  в контейнере 3, имеющем верхнюю концевую стенку 9, причем верхний конец стержн  выдаетс  из верхней концевой стенки. Отверстие , через которое стержень выходит из стенки заделываетс  керамическим цементом 10.A package of another form (Fig. 5) collects. with ring-shaped briquettes 1 pre-positioned on the rod 7 and held in a certain position with pins 8. Pre-assembled bricks and the rod are installed in container 3 having an upper end wall 9, with the upper end of the rod extending from the upper end wall. The hole through which the rod exits the wall is sealed with ceramic cement 10.

Брикеты изготавливаютс  из стального скрапа или железной стружки прессованием и имеют плотность от 25 до 50% плотности жидкого металла. Они прессуютс  в штампах кольцеобразной формы. Брикеты погружают в расплавленный металлический магний , который насыщает промежутки прессованных металлических кусочков. Затем несколько кольцеобразных брикетов укладывают один на другой и размещают в металлическом контейнере и через весь этого узел пропускают стержень. Узел удерживают на стержне пальцами-фиксаторами, введенными в стержень под дисками или брикетами. Если требуетс  могут быть использованы графитовые стержни. Блок реагентов погружаетс  в чугун и удерживаетс  под поверхностью металла. В течение первой минуты контейнер начинает раствор тьс  в металле и магний взаимодействует с чугуном, уменьша  содержащие серы в металле. Магний освобождаетс  из бриктов быстро, но не бурно . После трех или четырех минут больща  часть магни  раствор етс  и через п ть, шесть минут брикет и стержень сами начинают расплавлтьс . Такой пакет можно поднимать и опускать из металла, если это требуетс .Briquettes are made from steel scrap or iron shavings by pressing and have a density of from 25 to 50% of the density of the liquid metal. They are pressed into ring-shaped dies. Briquettes are immersed in molten magnesium metal, which saturates the intervals of pressed metal pieces. Then several ring-shaped briquettes are placed one on another and placed in a metal container and a rod is passed through the entire assembly. The node is held on the rod with fingers-clips inserted into the rod under the discs or briquettes. If required, graphite rods can be used. The reagent block is immersed in the cast iron and held below the metal surface. Within the first minute, the container begins to dissolve in the metal and the magnesium reacts with the iron, reducing the sulfur content in the metal. Magnesium is released from the bricks quickly, but not violently. After three or four minutes, most of the magnesium dissolves and after five, six minutes the briquette and the core themselves begin to melt. Such a bag can be raised and lowered from metal, if required.

Первоначальное содержание серы в чугуне было 0,041°/о, а после обработки блоком реагентов 0,023%. Блок прост и недорог в употреблении.The initial sulfur content in the iron was 0.041 ° / o, and after processing with the reagent unit 0.023%. The unit is simple and inexpensive to use.
