[0021] In order to deepen the understanding and knowledge of the present invention, the present invention will be further described and introduced in conjunction with the accompanying drawings.

[0022] Such as figure 1 — Figure 4 , A Φ500 segmented starting block head pouring connector, including a steel frame, a backing plate 1 and a hook head 10. The steel frame is a truncated cone-shaped steel cage welded by 26 Φ10 round steels, specifically one The Φ10 round steel 2 with a length of 1383 mm is used as the top beam of the steel cage, a Φ10 round steel 3 with a length of 1257 mm is used as the bottom beam of the steel cage, and 24 Φ10 round steel 4 with a length of 205 mm are used as the bottom beam. The connecting beams between the top beam and the bottom beam, wherein the diameter of the top beam is 400 mm and the diameter of the bottom beam is 450 mm, and all the connecting beams are evenly distributed between the top beam and the bottom beam at an angle of 15°. The backi...

Abstract

The invention provides a casting connector of a 500-diameter section dummy bar head in order to solve the problem of difficult ingot disconnection caused by cold material accumulation in a connector in the prior art. The casting connector comprises a steel bar framework, a base plate and a hook head, wherein the steel bar framework is formed by welding multiple pieces of round steel with the diameter of 10 mm; the base plate is aslant supported on the outer side of the bottom of the steel bar framework through multiple pieces of round steel with the diameter of 10 mm; the hook head is formed by welding multiple pieces of screw-thread steel and is welded and fixed to the bottom of the steel bar framework. The casting connector is ingenious in whole structural design, simple and reliable in structure, low in cost and convenient to use; a steel bar protective cage is put into a steel pipe before casting, an average interval of 20 mm is kept between the periphery of the protective cape and the inner wall of the steel pipe, then the hook is put into a dovetail groove, cold materials are put finally and can be fully melt, and a good ingot disconnection effect is ensured.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy continuous casting, in particular relates to a continuous casting production auxiliary equipment, in particular to a Φ500-section face dummy head pouring connector. Background technique [0002] Continuous steel casting refers to the molten steel held in the ladle that meets the requirements and is continuously poured into the crystallizer that has been blocked by the dummy bar through the tundish. After forming a solid primary shell in the crystallizer, it continuously enters the secondary cooling room and passes through the secondary cooling chamber. The process of cooling and solidification is called continuous casting for short. The traditional production process controls the flow of molten steel entering the crystallizer by using stopper rods in the tundish to open and close the nozzle, and installs connectors on the dummy head inserted into the lower mouth of the crystalliz...
