Continuous casting utter misery demolding device and demolding method thereof

Abstract

The invention provides a continuous casting utter misery demolding device and a demolding method thereof. The device comprises a first conveying line and a second conveying line which are arranged ina parallel connection manner and are used in turn and further comprises a water and steam separation device connected with the first conveying line and the second conveying line, a flow meter connected with the water and steam separation device, and a combustor with the flow meter; the first conveying line and the second conveying line each comprise an acetylene gas generation device, a washing device, a drying device, a pressure rise device and a pressure stabilizing device. The device has the following beneficial effects that acetylene can be completely combusted, the acetylene gas can be effectively prevented from being mixed in acetone for combustion, the carbon powder coating effect is improved, the service life of a crystallizer is prolonged, and the casting blank surface quality isimproved.

Description

technical field [0001] The invention belongs to the technical field of casting carbon-coating demoulding, in particular to a continuous casting charcoal-coating demoulding device and a demoulding method thereof. Background technique [0002] Continuous casting carbon coating demoulding refers to the use of acetylene and oxygen or air incomplete combustion during the continuous casting of high-melting metals, and the carbon powder produced by the flame is coated around the crystallizer to form a thin and uniform protective film. It not only plays the role of heat insulation, but also has the effect of demoulding. [0003] The existing continuous casting and rolling production line system uses bottled acetylene to be connected in parallel in the form of a busbar and mixed with oxygen or air for incomplete combustion to complete the carbon coating operation. Because bottled acetylene is a process of compressing gaseous acetylene into the bottle by dissolving acetylene in aceto...

AI Technical Summary

Problems solved by technology

Because bottled acetylene is a process of compressing gaseous acetylene into the bottle by dissolving acetylene in acetone, during the process of releasing gas from bottled acetylene, part of the acetone will also flow into the pipeline and burn with it, which will easily cause pipeline blockage, coating Inhomogeneity of the layer, uneven casting surface, short crystallizer life, etc. In addition, the gas pressure of bottled acetylene will continue to decrease with the extension of use time, which brings great difficulty to the control of the casting process. Finally, bottled acetylene When the gas pressure is lower than the requirements of the casting process, some gas remains, but it can no longer be used, and the gas cannot be completely consumed, which increases the production cost in disguise
