Ladle Slide Gate Type LQG-B3-1

    

1Constitution and Working principleLQG-B3-1 ladle slide gate is composed of the housingthe carrier framethe sliderthe spring module and the drive units,etc. The mechanism is divided into two parts by the plate. The housing and the carrier frame are the fixed part, the slider and the spring module are the moving part .The nozzle and the bottom plate are fixed in the housing ,the slide plate and the exchangeable collector nozzle are fixed in the carrier frame, the slider makes reciprocal moving in the carrier frame. There is a constant and equal interface pressure on the bottom and slide plate setted up by the spring module, and the drive units make the slider reciprocal moving, so as to keep the speed of the flow

2NamingThe LQ series ladle slide gate are named by the maximum diameter of hole and the working stroke of the slide gate nozzleFor exampleLQG60120B3-1LQmeans the product is designed by Jinan Linquan Co., LtdGmeans the product is designed for ladle60 means the maximum diameter of the hole of the slide gate nozzle is 60mm120 - means the working stroke of the slide gate nozzle is 120mmB3-1- means the first type of the third generation of the left or right opening mechanism

3Technical Characteristics3.1 Framed elastic compression structure, the plate is compressed by the spring, thus the interface pressure is easy to set up, constant, equal ,accurate ,unaffected by the high temperature and the human factor. The different changes created by the heat expansion and the worker operation are absorbed by the spring, so the mechanism can work well throughout the constant and the equal pressure.Door type with automatic surface pressure establishment. The active surface is the left or right gate type structure, divided into the fixed part and the moving part by the bottom and the slide plate, and join together with the spring module. After the gate closes one side, the carrier frame is locked tightly by the spring module, starts the hydraulic cylinder to push the slider to the working position, as soon as the surface pressure automatically established, simple to use, reasonable and scientific structure3.3 Constant pressure transmission structure. When in working conditions, in traveling range the pressure transmitting point is established around the center of the nozzle hole constantly, does not change with the sliding. This pressure transmission structure is more reasonable, equal and safe.3.4 Spring insulated structure. The design had taken the high temperature to the elastic part influence in consideration, so it has used the unique heat insulation design and the reasonable spring arrangement, lets the spring far away from high temperature area, maximum limit reduces the heat load. And it has the air-coolled equipment, resulting in safer and more reliable, longer life3.5 The main body is the high intensity and anti-high temperature material, so its service life is long.3.6 Elastic part for the thermostable column helical spring, then it saves time, reduces manpower, reliable, long life and low cost.
