一种可在线更换出钢口端砖的出钢口
摘要：
一种可在线更换出钢口端砖的出钢口，其包括，按出钢口长短不同选择不用尺寸、块数后组合的出钢口套筒砖、依次连接于出钢口套筒砖的一端的出钢口端砖和内水口砖；其特征是，所述的出钢口端砖与内水口砖相对的一面开有一凹槽，凹槽内嵌设一与凹槽相匹配、可以单独更换的更换体，该更换体的外端面抵靠内水口砖。本实用新型可以在线更换出钢口端砖，使出钢口寿命比原有技术提高30％以上，提高产能和降低成本。
摘要（英）：

A steel tapping hole capable of replacing steel tapping hole end bricks on line comprises a steel tapping hole sleeve brick combined after selecting steel tapping holes with different sizes and blocks according to the different lengths of steel tapping holes, a steel tapping hole end brick and an inner water hole brick that are sequentially connected at one end of the steel tapping hole sleeve brick. The steel tapping hole is characterized in that the surface of the steel tapping hole end brick opposite to the inner water hole brick is provided with a groove that is internally embedded with a replacement body, wherein the replacement body is matched with the groove and can be separately replaced, and the outer end surface of the replacement body presses against the inner water hole brick. The steel tapping hole can replace steel tapping hole end bricks on line, prolong the service life of the steel tapping hole by over 30 percent compared with the original technology and improve the output and reduce cost.
