Abstract
The invention provides a sliding nozzle mechanism used for tundish centrifugal pouring. By means of the sliding nozzle mechanism, the liquid steel pouring flow can be controlled, and the pouring operation can be stopped at any moment. The mechanism comprises a base fixed to the outer wall of a tundish, and an oil cylinder fixed on the base, a piston rod of the oil cylinder is connected with a union joint, the union joint is connected with a sliding body, and a support is arranged at the outer side of the sliding body; an upper water port is formed at an outlet of the tundish, an upper sliding plate, an intermediate sliding plate and a lower sliding plate are sequentially arranged at the outer side of the upper water port, the upper sliding plate is located inside the base, the intermediate sliding plate is located inside the sliding body, the lower sliding plate is located inside the support, and a lower water port is formed outside the support.
Description
Technical field
The present invention relates to a kind of sliding nozzle device, especially a kind of slide gate mechanism of middle bag centrifugal casting.
Background technology
During current domestic middle bag centrifugal casting, wrap, can not close during cast in adopting resistance to material to be directly connected in, flow is difficult to control, and in middle bag, molten steel must water and could stop.
This mechanism of invention, can control the flow of pouring molten steel in centrifugal casting process, can stop cast at any time.
Summary of the invention
The invention provides a kind of flow controlling pouring molten steel, stop the slide gate mechanism of the middle bag centrifugal casting of pouring into a mould at any time.
Realize the slide gate mechanism of a kind of middle bag centrifugal casting of the object of the invention, comprise the base be fixed on middle bag outer wall, be fixed on the oil cylinder on base, the piston rod of described oil cylinder connects connector, described connector connects slide mass, is provided with support outside described slide mass; The exit of described middle bag is provided with filling pipe end, is provided with upper slide, middle slide plate and lower skateboard successively outside described filling pipe end, and described upper slide is positioned at base, and described middle slide plate is positioned at slide mass, and described lower skateboard is positioned at support, is provided with the lower mouth of a river outside described support; Described support is fixed on base.
Described support comprises body, spring pull bar, spring and spring bearer plate; The both sides of described body are provided with groove, described bottom portion of groove and spring bearer plate are equipped with two through holes, described spring pull bar is through through hole, one end of described spring pull bar is fixed on base, the other end withstands on spring bearer plate by flange, described spring pull bar is installed with spring, and described spring is between spring bearer plate and bottom portion of groove.
Described middle bag outer wall is provided with pin and wedge, and described base is arranged on pin by alignment pin, and described wedge is positioned at below base locks base.
The beneficial effect of the slide gate mechanism of a kind of middle bag centrifugal casting of the present invention is as follows:
The slide gate mechanism of a kind of middle bag centrifugal casting of the present invention, can control the flow of pouring molten steel, stops cast at any time.
Accompanying drawing explanation
Fig. 1 is the structural representation of the slide gate mechanism of a kind of middle bag centrifugal casting of the present invention.
Fig. 2 is the explosive view of the slide gate mechanism of a kind of middle bag centrifugal casting of the present invention.
Detailed description of the invention
As shown in Figure 1, 2, the slide gate mechanism of a kind of middle bag centrifugal casting of the present invention, comprise the base 2 be fixed on middle bag 12 outer wall, be fixed on the oil cylinder 1 on base 2, the piston rod of described oil cylinder 1 connects connector 3, described connector 3 connects slide mass 4, is provided with support 8 outside described slide mass 4; The exit of described middle bag 12 is provided with filling pipe end 6, be provided with upper slide 7, middle slide plate 5 and lower skateboard 9 outside described filling pipe end 6 successively, described upper slide 7 is positioned at base 2, and described middle slide plate 5 is positioned at slide mass 4, described lower skateboard 9 is positioned at support 8, is provided with the lower mouth of a river 10 outside described support 8; Described support 8 is fixed on base 2.
Described support 8 comprises body, spring pull bar 13, spring 15 and spring bearer plate 14; The both sides of described body are provided with groove, described bottom portion of groove and spring bearer plate 14 are equipped with two through holes, spring pull bar 13 is positioned at through hole, one end of described spring pull bar 13 is fixed on base 2, the other end withstands on spring bearer plate 14 by flange, described spring pull bar 13 is installed with spring 15, and described spring 15 is between spring bearer plate 14 and bottom portion of groove.
Described middle bag outer wall is provided with pin 18 and wedge 17, and described base 2 is arranged on pin 18 by alignment pin 16, and described wedge 17 is positioned at below base 2 locks base 2.
Operation principle of the present invention: base 2 and support 8 are standing parts, and slide mass 4 is slippers.It is motionless that filling pipe end 6 is contained in middle bag 12, upper slide 7 is loaded on base 2 internal fixtion, and it is motionless that lower skateboard 9 is loaded on support 8 internal fixtion, and the slide mass 4 that middle slide plate 5 is housed can reciprocatingly slide between support 8 and base 2.Duty lower bottom base 2 and support 8 are connected into one by spring pull bar 13, upper slide 7, active interface between middle slide plate 5 and lower skateboard 9 by grooves on two sides on support 8 built with spring pull bar 13, spring bearer plate 14 and spring 15 set up constant, uniform interfacial pressure.Oil cylinder 1 drives slide mass 4 to drive middle slide plate 5 reciprocating by connector 3, make the number that staggers between the circular hole on the circular hole on middle slide plate 5 and upper slide 7 and lower skateboard 9 or align, thus realize controlling the flow of pouring molten steel, and reach and stop cast at any time.
Embodiment recited above is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; do not departing under the present invention designs spiritual prerequisite; the various distortion that the common engineers and technicians in this area make technical solution of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
