An energy-saving cutting device for continuous casting billet cutting

Abstract

The invention discloses an energy-saving cutting device for continuous casting billet cutting. A conveying frame and a placing piece are snap-fitted and installed, wherein the placing piece includes a recovery box, and two of the recovery boxes are arranged symmetrically with the conveying frame as the center. The invention relates to the technical field of heating cutting. The energy-saving cutting device for continuous casting billet cutting can effectively solve the problem that in the prior art, the temperature of the continuous casting billet itself is relatively high, and the metal can be heated to the ignition point without excessive heat. The metal of the flame is blown by the fast-flowing gas, and it is easy to splash around, which is easy to injure people and has potential safety hazards. At the same time, a large number of metal impurities generated after flame cutting need to be cleaned manually, which increases the labor intensity.

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 iron and 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...

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing 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 does not require 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
