 TH-AII型系列鋼包滑動水口機構分為,TH310-A55II、TH359-A60II、TH410-A70II、其中TH410-A70II機構介紹如下:
一、 TH410-A70Ⅱ型號解釋
TH —表示該機構為泰禾公司所設計410— 表示滑板磚的標準長度尺寸為410 mm
A — 表示機構為上下開門
70 — 表示滑板磚的最大標準孔徑為ф70 mm  Ⅱ — 表示為第二代機構 
二、 TH410-A70Ⅱ機構的主要技術參數
機構外型尺寸:   1240×520×346  (長×寬×高) 
機構壽命:                ≥2000爐
工作行程:                150 mm 
使用彈簧種類:        碟形彈簧
使用彈簧數量:        6×2組
彈簧使用溫度:        ≤450 ℃
三、 TH410-A70Ⅱ結構原理
        TH410-A70Ⅱ鋼包滑動水口機構由:底座、支架、滑動小車、彈簧組件及驅動組件等組成。
       機構以上、下滑板為界面分開,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不動,下滑板磚、下水口磚固定在滑動小車內,滑動小車可以在支架內往復滑動。滑動小車進入工作位后,彈簧便自動產生壓力,無需人工調整,機構給滑塊傳遞壓力的四個壓力點不變,始終建立在以上水口為中心的周圍。動力源通過驅動組件驅動滑動小車,從而實現對鋼水的節流。
四、 TH410-A70Ⅱ技術特點
        4.1壓力區域建立點恒定。滑塊在工作行程范圍內,機構給滑塊傳遞壓力的四個壓力點不變,始終建立在以上水口為中心的周圍。
        4.2 機構為框架式彈性壓緊結構,采用碟形彈簧壓緊滑板。結構合理、彈簧壽命長,此種結構的滑板界面容易建立一種恒定、均勻的壓力狀態,不受高溫和人為因素的影響。使用時溫度變化造成的熱膨脹及工人操作習慣不同造成的變化被彈簧所吸收,滑板界面始終處在一個恒定、均勻的壓力狀態下,使機構運行更平穩、安全性更高。
        4.3采用國內外先進的門式結構,機構拆裝耐火材料非常方便、操作簡單。
        4.4機構裝有風冷裝置,使機構使用更安全、可靠,彈簧壽命更長。
        4.5可以滿足滑板多次連滑使用要求。




TH-AII type ladle slide gate mechanism
TH-AII type ladle slide gate mechanism include TH310-A55II、TH359-A60II、TH410-A70II.and the introduction of TH410-A70II is as follows:
1. Type explanation of TH410-A70II
TH —represents the mechanism is designed by TaiHe
410 —represents the standard length of the slide plates is 410 mm
A —represents the structure of  the mechanism is up /down to make the gate opened or closed.
70— represents the maximum standard plug hole of the slide plates is 70 mm 
Ⅱ— represents the mechanism is the second generation

2. the main technical parameters of TH410-A70Ⅱ mechanism
Dimensions:             1240×520×346  (L × W × H)                                  
Service life :             ≥2000  heats
Stroke:                 150 mm 
Spring type:             disk spring
Spring quantities:         6 x 2 groups
Operating temperature of spring:   ≤450 ℃

3.  Construction and principle of TH410-A70Ⅱ
H410-A70Ⅱ ladle slide gate mechanism comprises: housing. support. slider. springs component and cylinder bracket.
The combination of the upper and slider plate is a boundary. housing is fixed on the base of the bottom of the ladle. support is opening part. and slider is active part.  Ladle nozzle and upper plate are fixed in the housing and slider plate and exchangeable nozzle are fixed in the slider. slider component can slide in the support component. A uniform and constant interfacial pressure is established through the spring component in the plate boundary. Under the working condition. support and housing are hinged together through the safety pin hinge. Pressure is transmitted to plate boundary through the support slide bar and the slider slide bar. Driven by the hydraulic cylinder. thereby achieving the flow control. 

4.Technical Features of TH410-A70Ⅱ      

4.1 The pressure area is constant. Slider is within the working stroke. The four pressure points where the mechanism pass the pressure to the slider is unchanged and is always around the center of the ladle nozzle.

4.2 The mechanism is of frame type and elastic compression structure. using disk spring to compress slide plate. The structure is reasonable and springs have long service life. With such kind of structure. the slide interface is easy to establish a constant and uniform pressure state and is not affected by high temperatures and human factors. Changes in thermal expansion caused by temperature changes and workers operating habits are absorbed by the spring when it is on service. The slide interface is always in a constant and uniform pressure state. which make the mechanism running more smoothly and security.   

4.3 Adopting the advanced gate structure. Disassembly of refractory is very convenient and easy operation.     

4.4 The mechanism has air cooling device to enable more secure and reliable operation and long spring service life.

4.5 It can satisfy the use requirements of the many times and continuous slide of the slide plate.
