Technology Introduction:

On the basis of the third-generation "Sizing spout quick-change device with strong sealing" and combining with the new requirements put forward by the current users, our company independently researched and developed the fourth-generation quick-change device "Sizing spout quick-change casting device with accurate positioning and strong sealing" (Patent No.: ZL 2011 2 0014923.4), which adopts the technologies of four-guide column depressing guiding, countersunk hole-type rigid rolling connection, bi-directional fixing cylinder bracket Accurate positioning, integral moulding on the water outlet and other technologies, with the water outlet in place accurately, simple structure, easy to operate, safe and reliable use and other characteristics, is widely used.

The main advantages are:

1, accurate positioning of water spout: the cylinder bracket of this utility model adopts two-way fixation in vertical and horizontal directions, which improves the connection rigidity of the cylinder bracket and is not easy to produce deformation, so that the cylinder is accurately positioned in the process of replacing the lower water spout advancement, which hardly produces error, so that the correspondence between the lower water spout and the upper water spout when replacing the lower water spout is accurate, which improves the service life of the lower water spout and further ensures the quality of the molten steel; this The utility model also has the advantages of relatively low manufacturing costs, the overall structure is not easy to damage, long service life and so on.

2、Seamless connection of the upper water outlet: the quick-change upper water outlet used in this device is produced by adopting integral moulding technology. So that the zirconium core and the mother to achieve a seamless connection between. Eliminate the original quick-change spout in use due to clay failure caused by the zirconium core displacement, the phenomenon of clamping steel caused by the tampering of steel type of accidents. At the same time, the integral moulding spout production operation is simple, energy consumption is greatly reduced, is a high-quality energy-saving products, greatly improving the service life of the intermediate package of the quick-change device.

3、High-precision water outlet: The quick-exchange water outlet used in this device is produced by the integral forming technology. Make seamless connection between iron shell and mother body. Eliminate the original quick-exchange spout due to assembly reasons caused by the skew in the use of the spout gap is too large to appear tampering with the steel phenomenon and due to the assembly of the mud caused by the shell, replacement of deformation and other phenomena. Integral moulding downspout has more regular shape, better strength, improved service life and other characteristics, which can significantly reduce the number of times of downspout replacement and improve the life of the intermediate package.

4、Segmented support guide: the lower guide plate adopts the lever-type pressure application method, and the support plate is changed from the whole to two segments, which increases the flexibility of the action of the lower guide plate, and ensures that the force of the spring is uninterruptedly applied to the lower spout, so that the upper surface of the lower spout can be tightly sealed on the lower surface of the upper spout. In the whole process of use, uninterrupted pressure can compensate for the deformation of the device due to heat, so that the upper and lower spouts have been in a tightly compressed state.

5, countersunk hole type connection: the use of four guide columns under the guide, countersunk hole rolling lever connection, so that the overall height of the mechanism to reduce the flexibility of action, compact structure. The installation space of immersed spout is enlarged, which is conducive to the installation and replacement of immersed spout.

Adopting two-way fixed cylinder bracket, segmental support guide, countersunk hole connection, integral moulding quick-change upper and lower spouts, "Accurate positioning sealing strong sizing spout quick-change casting device" has the features of more convenient installation, safer and more reliable use, intermediate packet life enhancement, energy saving, etc., which is highly praised by the users.
