| titleOfInvention | A kind of insert pipe for vacuum circulation degassing furnaces and preparation method thereof |
| abstract | The present invention relates to a kind of insert pipe for vacuum circulation degassing furnaces and preparation method thereof, belong to the external refining field of metallurgical production.The invention provides a kind of insert pipe for vacuum circulation degassing furnaces, the pouring layer that tubular stinger comprises tubular steel structure, builds the refractory brick on steel construction inwall by laying bricks or stones and be formed on steel construction outer wall, pouring layer comprises the lower pouring layer and upper layer that contact with each other, wherein, upper layer is when carrying out vacuum circulation degassing refining and slag contacts, lower pouring layer is when carrying out vacuum circulation degassing refining and steel contacts, and lower pouring layer external diameter is less than upper layer, forms T-type structure; Further, ZrO is comprised in the composition of lower pouring layer mould materialn 2 and TiOn 2 , wherein, ZrOn 2 add-on account for the 2-5% of lower pouring layer mould material gross weight, TiOn 2 add-on account for the 2-8% of lower pouring layer mould material gross weight.The present invention adopts lower pouring layer external diameter to be less than and upper layer, forms T-type structure, the dry slag of basically eliminate and steel contacts mould material, reduces scarfing cinder amount. |
