Title:
CONVERTER SLAG STOPPING SLIDE GATE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/036136
Kind Code:
A1
Abstract:
A converter slag stopping slide gate device with left and right gate blocks. An F-shaped fixed gate hinge seat (10) is provided on two sides of the fixed frame (1). The distance from a central hole of the gate hinge seat to a bottom of an internal slide gate block slot is 172-177 mm. A T-shaped spring cavity (51) is provided on two sides of an opening and closing frame (2) to accommodate the width of a spring pressure plate and a slide rail. A top side and a bottom side of the spring cavity are thickened and provided with an axial opening of a moving gate. The fixed frame (1) is fixedly provided on an adjustment frame (70), and will not exert any interference when the gate is opened at an angle of 110° or greater. When subject to pressure during operations, a surface pressure screw bolt (52) passes through a spring pressure plate (54), a spring (53), and the opening and closing frame (2), and is rotationally tightened on the fixed frame (1). The slide rail evenly transmits a surface pressure to an area between the inner slide gate block and an outer slide gate block. The device provides a large gate opening angle, low spring pressure fluctuations, even and constant transmission of surface pressure, easy off-line operations, simple maintenance, low costs, and excellent safety performance.
