Description

Известен способ дроблени  струи при обработке металла синтетическим шлаком, когда струю металла дроб т тазом при поступлении его в изложницу. Металл на обработку синтетическим шлаксм при этом поступает в виде капель.There is a known method of crushing a jet when processing metal with synthetic slag, when a jet of metal is crushed by a pelvis when it enters the mold. The metal to be treated with synthetic slags comes in the form of droplets.

По предлагаемому способу дл  устранени  вторичного окислени  металла лри дроблении, повышени  эффективности перемешивани  его со шлаком и снижени  содержани  серы и неметаллических включеиий в стали дробление струи металла производ т в слое шлака за счет применени  корундовых пластин.According to the proposed method for eliminating the secondary oxidation of metal during grinding, increasing the efficiency of mixing it with slag and reducing the sulfur content and non-metallic inclusions in steel, the crushing of a metal jet is performed in the slag layer by using corundum plates.

Способ предусматривает наводку синтетического шлака в изложнице расплавлением его специальным устройством пли заливкой в жидком виде. На жидкий шлак из ковша заливают металл. После создани  подушки из металла в шлак опускают корундовую пластину, размеры которой на 20-30 мм меньше ноперечного сечени  изложннцы. Удельный вес пластины больше шлака, но меньше металла, так что она плавает на поверхности металла подThe method involves the placement of synthetic slag in a mold by melting it with a special device or by pouring it in a liquid form. Metal is poured onto the liquid slag from the ladle. After creating a metal cushion, a corundum plate is lowered into the slag, the dimensions of which are 20-30 mm smaller than the cross section of the set. The specific gravity of the plate is greater than slag, but less than metal, so that it floats on the surface of the metal under

шлаком. Пластина «а 95% состоит из корунда, в качестве св зующего примен ют с.молу. При дальнейшей разливке стру  .металла проходит через шлак и, зДар  сь о пластину, размельчаетс  на капли, которые снова проход т через шлак вверх и вниз и затем стекают в зазор между изложницей и пластииой.slag. The 95% plate consists of corundum, cmola is used as a binder. During further casting, the metal passes through the slag and, on the plate, is crushed into droplets, which again pass through the slag up and down and then flow into the gap between the mold and the plastic.

Содержание серы в металле понижаетс  в 3-С раз по сравнению с ковшовой пробой, иThe sulfur content in the metal decreases by a factor of 3 ° C compared to bucket breakdown, and

повышаетс  чистота стали по неметаллическим включени м.The purity of the steel is improved by non-metallic inclusions.

Предмет изобретени Subject invention

Способ дроблени  струи металла ири обработке его С1П1тетическим шлаком, отличающийс  тем, что, с целью устранени  вторичного окислени  металла, более эффективного перемешивани  его со и лаком и повышени  чистоты стали по сере и неметаллическим включени м , дробление струи металла производ т в слое шлака за счет при.меиени  корундовых пластин.The method of crushing the metal stream and processing it with S1P1tetic slag, characterized in that, in order to eliminate the secondary oxidation of the metal, to mix it more efficiently with lacquer and increase the purity of the steel over sulfur and nonmetallic inclusions, the metal stream is crushed in a slag layer due to on.methienes corundum plates.
