Energy-saving cutting device for continuous casting billet cutting

Abstract

The invention discloses a continuous casting billet cutting energy-saving type cutting device which comprises an operation main body, the operation main body comprises a placing seat, a cutting device is arranged at the top of the placing seat, the placing seat is provided with a conveying frame and a placing piece in a clamped mode through a limiting block arranged at the top of the placing seat, and the placing piece comprises a recycling box. The number of the recycling boxes is two, and the recycling boxes are symmetrically distributed with the conveying frame as the center. The energy-saving cutting device for cutting the continuous casting billet can effectively solve the problems that in the prior art, the temperature of the continuous casting billet is high, metal can be heated to the ignition point without excessive heat, in the cutting process, molten metal is blown by fast flowing gas and is prone to splashing to the periphery, people are prone to be accidentally injured, potential safety hazards exist, and the cutting efficiency is high. And meanwhile, a large amount of metal impurities generated after flame cutting need to be manually cleaned, and the labor intensity is increased.

Description

technical field [0001] The invention relates to the technical field of heating cutting, in particular to an energy-saving cutting device for cutting a continuous casting billet. Background technique [0002] Continuous casting and cutting is a method of using molten steel to solidify and form in the process of producing various steel products in steel plants. The specific method is that the molten steel continuously passes through the water-cooled crystallizer, solidifies into a hard shell, and then continuously pulls out from the outlet at the bottom of the crystallizer. [0003] The flame cutting of metal is a process of combustion reaction between metal and oxygen. The function of gas is to release heat through its own combustion to heat the metal to the ignition point. Due to the high temperature of the continuous casting billet itself, the metal can be removed without excessive heat. It is heated to the ignition point to cut off the billet; however, during the cutting ...

AI Technical Summary

Problems solved by technology

Aiming at the above-mentioned shortcomings in the prior art, the present invention provides an energy-saving cutting device for continuous casting slab cutting, which can effectively solve the problem in the prior art that the temperature of the continuous casting slab itself is relatively high, and it does not need too much heat to cut The metal can be heated to the ignition point. During the cutting process, the molten metal is blown by the fast-flowing gas, and it is easy to splash around, which is easy to accidentally injure people and pose a safety hazard. At the same time, a large amount of metal impurities produced after flame cutting need to be cleaned manually. The problem of increasing labor intensity
