H系列自動加壓滑動水口節(jié)流機構(gòu)為框架式彈性壓緊結(jié)構(gòu)的機構(gòu)，底座、支架、滑動小車及液壓驅(qū)動四大部分。其中底座、支架是固定部分；滑動小車是活動部分，上水口磚、上滑板磚固定在底座內(nèi)不動；下滑板磚、下水口磚固定在滑動小車內(nèi)，配合液壓系統(tǒng)，使滑動小車在支架內(nèi)往復(fù)滑動，從而實現(xiàn)對鋼水的節(jié)流，該類型機構(gòu)結(jié)構(gòu)簡單、操作方便，是目前國內(nèi)鋼鐵企業(yè)在煉鋼控流技術(shù)上比較認可的機構(gòu)類型。

Type H Automatic Pressure-loading Slide Gate System for steel ladle is a frame type mechanism with elastic tensioning structure and consisting of four parts, namely, base, stand, sliding car and hydraulic driving system, among which base and stand are stationary part, and sliding car is moving part. Upper nozzle and plate are fixed within the base without moving; lower plate and nozzle are fit within the sliding car, driven by hydraulic system and with its reciprocating motion in the stand, flow control over molten steel is realized. Featured with simple framework and easy operation, such sliding system is well accepted by domestic steel plants in terms of flow control technology.
