Therefore, to be replaced by the better performance of short hydraulic clay gun. And previous use blast furnace equipment of electric mud bubble pared, hydraulic mud bubble with mud making large thrust, pacted mud, pressing force is stable, pact structure, convenient operation, better adapt to the blast furnace, the advantages of high pressure, oil pressure device is not installed in the mud gun body, thus simplifying the mud gun structure. In view of the merits of the hydraulic clay gun and electric gun shortings, both at home and abroad in the development of the hydraulic clay gun, so that the hydraulic mud gun technology has been developed rapidly. The hydraulic clay gun is mainly posed of five parts: the clay beating mechanism, a pressing mechanism, a rotating mechanism, a locking mechanism and hydraulic control system.Key words: Hydraulic transmission、Mud bubbles、Type BG1第一章 緒論泥炮又稱為堵出鐵口機器。煉鐵爐出鐵后，必須迅速用耐火泥將出鐵口堵塞住，堵鐵口操作就是用泥炮進行的。泥泡按照驅動方式的不同泥炮可分為氣動式、電動式和液壓式。氣動式泥炮由于活塞推力小以及打泥壓力不穩定而被淘汰。目前我國高爐上廣泛使用電動泥炮，由于高爐大型化和高壓操作技術的實現以及爐前操作機械化的要求；再加上電動泥炮在實際使用中存在的問題，例如：外形尺寸大，特別是高度太大，妨礙出鐵口附近的風口進行機械化更換工作；打泥活塞推力不足，尤其采用無水泥炮時；絲杠及螺母磨損快、更換困難等等原因；促使液壓泥炮得到迅速發展。本論文在 BG 型液壓泥泡的基礎上進行設計，通過從打泥機構，壓炮機構，旋轉裝置三個方面進行了全方位的計算
