Description

При изготовлении конверториы.х фурм путем трамбовки в формах металлические сердечники, образующие соила фурмы, сильно зажимаюгс  в теле затрамбованной фурмы. Дл  извлечени  сердечников с помощью распорных болтов требуютс  значительные усили . Вмес1е с тем применение распорных болтов зат гивает извлечение фурмы из формы и приводит к частым ремонтам формы, вследствие срыва резьбы на распорных болтах и кромках корпуса формы.In the manufacture of converters. X tuyeres by tamping in the forms of metal cores that form the force of the tuyere, it is strongly clamped in the body of the tucked-down tuyere. To extract the cores using spacer bolts, considerable effort is required. Together with this, the use of spacer bolts tightens the removal of the tuyere from the mold and leads to frequent shape repairs, due to the breakdown of the thread on the spacer bolts and the edges of the mold body.

Предлагаема  форма дл  пневматического трамбовани  конверторных фурм отличаетс  от известных тем, что дл  извлечени  сердечников из тела затрамбованной фурмы используетс  автомобильный домкрат, а сердечники периодически поворачиваютс  дл  облегчени  их извлечени .The proposed pneumatic tamping form for the converter tuyeres differs from the known ones in that a car jack is used to remove the cores from the body of the tucked tuyere, and the cores are rotated periodically to facilitate their removal.

Применение предлагаемой формы допускает производство конверторных фурм повыщенной стойкости из корунда, муллита, хромо-магнезита и др. вместо обычных шамотных фурм.The application of the proposed form allows the production of converter tuyeres of increased resistance from corundum, mullite, chrome-magnesite, etc. instead of the usual chamotte tuyeres.

На чертеже изображена схема предлагаемой формы. Дл  изготовлени  фурмы в эту фор.му засыпают порци ми тощую щихту и трамбуют пневматической трамбовкой. Во врем  трамбовани  сердечники / периодически поворачивают вокруг своих осей с помощью гаечного ключа, что уменьщает прилипание к ним затрамбованной щихты и облегчает в дальнейщем извлечение их из тела фурмы. После набивки фурмы снимают накладку -2 и выравнивают поверхность рабочего конца фурмы.The drawing shows a diagram of the proposed form. To make a tuyere, this form is filled in with portions of lean skin and rammed with pneumatic ramming. During ramming, the cores / are periodically turned around their axes with a wrench, which reduces the adherence of the rammed guard to them and facilitates their further removal from the tuyere body. After packing the tuyere, remove the cover -2 and level the surface of the working end of the tuyere.

Дл  извлечени  сердечников / из фурмы 3 привод т в действие автомобильный домкрат 4 путем вращени  ручки 5. Указанный домкрат заключен в коробку 6, имеющую верхнюю крыщку 7 и нижнюю крышку 8. В верхней крышке 7 укреплены сердечники 1. Домкрат при своем подъеме давит на ползун, состо щий из основани  9 и четырех пальцев 10. Ползун своими пальцами давит на дно формы // и поднимает последнюю на 50-100 мм вместе с корпусом формы 12 и затрамбованной в нем фурмой 3. Затем снимают скобы 13 путем выбивани  клиньев //, и корпус формы 12 вместе с фурмой 3 перенос т, например, электротельфером на дерев нный щиток.To remove the cores / from the tuyere 3, the car jack 4 is activated by rotating the handle 5. The jack is enclosed in a box 6 having an upper lid 7 and a lower cover 8. In the top cover 7, the cores 1 are fastened. consisting of a base 9 and four fingers 10. The slide with its fingers presses the bottom of the mold // and lifts the latter by 50-100 mm together with the body of the mold 12 and the tuyere 3. tamped in it. Then remove the brackets 13 by knocking out the wedges //, and the housing of the mold 12 together with the tuyere 3 is transferred, For example, an electric hoist on a wooden shield.
