Material conveying steel pipe structure used for continuous casting slag adding machine

Abstract

The invention provides a material conveying steel pipe structure used for a continuous casting slag adding machine. The material conveying steel pipe structure comprises a first material conveying steel pipe and a second material conveying steel pipe, the second material conveying steel pipe is sleeved in the first material conveying steel pipe, the first material conveying steel pipe and the second material conveying steel pipe are both provided with multiple sections of auger shafts, and the multiple sections of auger shafts are fixed to the pipe wall of the first material conveying steel pipe and the pipe wall of the second material conveying steel pipe through transmission square shafts and bearing pedestals. The multiple sections of auger shafts are fixed to the pipe walls of the steel pipes through the transmission square shafts and the bearing pedestals, slag automatically input by a feeding bin is free of wear under pushing of spiral blades of the auger shafts and flows smoothly, and meanwhile the slag is output through through holes of the bearing pedestals; the bearing pedestals are fixed through positioning screws, and therefore the bearing pedestals can be prevented from rotating; and the problems that due to the fact that the diameters of material conveying steel pipes are small, and only flexible shafts can be mounted in the pipes, the flexible shafts and the walls of the material conveying steel pipes are worn, the material conveying steel pipes and the spring flexible shafts are replaced due to wear within a short time, and the maintenance cost is high are solved, and the service life of equipment is prolonged.

Description

Technical field [0001] The present invention relates to the technical field of coated crystal slag, in particular, a conveying steel pipe structure for continuous casting slag. Background technique [0002] Adding a protective slag to the liquid steel surface of the crystallizer in the continuous casting production is an indispensable process. At present, the slag-sagage mode of the slab joint casting machine in my country is mostly manual, and the manual degeneration is large, the crystallizer is the slag layer. Uncomfortable causing roll residue and other issues. [0003] From the 1980s, it has developed automatic slag-slag-sagging equipment, and has developed a variety of crystallizers, and my country has also launched some similar products in recent years. These products not only greatly improve the working environment, and solve the crystallizer. The slag layer is uneven and easy to cause roll residues, but there is still the following main disadvantages: one is to feed the ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a feeding steel pipe structure for a continuous casting slag adding machine. The structure of the invention is simple, and at the same time, it can overcome the problems caused by the use of flexible shafts and the feeding steel pipe wall due to the small diameter of the feeding steel pipe. Wear and tear, replace the feeding steel pipe and spring soft shaft due to wear in a short period of time, and the maintenance cost is very high
