Novel bloom continuous casting machine emergency shutdown oil cylinder

Abstract

The invention discloses a novel bloom continuous casting machine emergency shutdown oil cylinder and relates to the field of metallurgy. The novel bloom continuous casting machine emergency shutdown oil cylinder comprises an oil cylinder upper flange, a cylinder body and an oil cylinder lower flange, wherein the oil cylinder upper flange, the cylinder body and the oil cylinder lower flange are fixedly connected with one another. An oil cylinder hanging lug is fixedly mounted at the end close to the oil cylinder upper flange. A piston is arranged inside the oil cylinder upper flange, the cylinder body and the oil cylinder lower flange in a penetrating manner. According to the novel bloom continuous casting machine emergency shutdown oil cylinder, the oil cylinder upper flange and the oil cylinder hanging lug are of integrated design, and the defect that in the process of site secondary assembling, seal damage is possibly caused is overcome; in addition, a connected threaded rod is stressed more uniformly, and the strength is more reliable; a countersunk head screw thread does not need to be exposed, an arc-shaped groove is large in mounting clearance, and mounting is easier and moreconvenient to conduct; the novel oil cylinder is optimized from original five main components into the three main components, a seal is reduced, the oil leakage risk is lowered, use safety and reliability performance of the oil cylinder is improved, and the service life is remarkably prolonged; and the repair cost of spare parts and the labor intensity of workers are greatly lowered.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a novel accident cut-off oil cylinder of a bloom continuous casting machine. Background technique [0002] At present, in the continuous casting process of the continuous casting machine, if there are production accidents such as steel breakout and pull-off, the billet cutting cylinder must be able to quickly cut off the liquid steel casting flow to ensure that the continuous casting machine crystallizer, vibrating table, sector, etc. The core equipment will not be burned by the liquid steel casting flow, that is to ensure the safe and reliable operation of the continuous casting machine equipment. At present, the billet cutting oil cylinders of domestic bloom continuous casting machines are mostly square flanges, and the five main parts of the oil cylinder lugs, upper flanges, cylinder blocks, piston rods, and lower flanges are tightly connected by full-length double-ended screws at fo...

AI Technical Summary

Problems solved by technology

During the production process of the continuous casting machine, the operator has to disassemble and assemble the slab cutting oil cylinder every time the group is changed. Due to the difficulty of installation, the time is too long. While increasing the labor intensity of the operator, the auxiliary time is long, which affects the production of the continuous casting machine efficiency
