Description

Изобретение относитс  к области металлургии и может быть использовано, в частности при получении изделий из черных металлов .The invention relates to the field of metallurgy and can be used, in particular, in the manufacture of ferrous metal products.

Известен способ получени  проката из черных металлов, включающий отливку слитков с последующей деформацией их в твердом состо нии с целью придани  формы и получени  необходимых физико-механических свойств издели  1.There is a known method for producing rolled products from ferrous metals, which includes casting ingots with their subsequent deformation in the solid state in order to shape and obtain the necessary physical and mechanical properties of the product 1.

Однако этот способ требует больщих капитальных затрат при значительных отходах металла.However, this method requires large capital expenditures with significant metal waste.

Известны также способы формировани  слитков в жидком состо нии, включающие литье металла в кристаллизатор, образо;ва1Нный электромалнитным полем индуктора, и последующее затвердевание получаемой заготовки путем подачи на нее охлаждающей среды 2, 3. Недостатком этих способов  вл етс  то, что сталь при переходе из жидкого состо ни  в твердое не измен ет своих свойств и поэтому требуетс  последующа ,деформаци  заготовки с целью ликвидации литой структуры и получбии  определенных механических свойств.There are also known methods for forming ingots in a liquid state, including casting a metal into a mold, the electric field of an inductor, and the subsequent solidification of the resulting billet by supplying a cooling medium 2, 3 to it. the liquid state into the solid does not change its properties and, therefore, subsequent deformation of the workpiece is required in order to eliminate the cast structure and obtain certain mechanical properties.

С. целью исключени  деформации заготовки , сниже1ни  расхода металла и уменьшени  капитальных затрат при производстве слитка литье стали производ т в электромагнитном переформирующем устройстве, где жидкий металл после получени  формы и размеров конечного издели  нагревают до необходимой температуры, обеспечивают дегазацию и удаление примесей, а затем перевод т в твердое состо  ние путем совместного снижени  мощности электромагнитного пол  и усиливающегос  действи  охлаждаюп;ей среды.C. To prevent deformation of the workpiece, reduce metal consumption and reduce capital costs in the production of ingot, steel is cast in an electromagnetic re-shaping device, where the liquid metal is heated to the required temperature after receiving the shape and size of the final product, degassing and removing impurities and then transfer t into a solid state by jointly reducing the power of the electromagnetic field and the amplifying effect of cooling.

Чертеж по сн ет предлагаемый способ. Металл из разливочного устройства 1 через отверстие круглого сечени  поступает в электромагнитное устройство 2, в которомThe drawing explains the proposed method. The metal from the casting device 1 through the round hole enters the electromagnetic device 2, in which

Then the metal is heated to a certain temperature, 200-250 ° C higher than the liquidus temperature, is passed at this temperature through a vacuum ka-3
