Abstract

The invention relates to a molten metal scum quick removal device and an operation method. The molten metal scum quick removal device structurally comprises a tapered scum collector, a tapered scum stopper, a scum collector lifting device and a scum stopper lifting device, wherein the tapered scum collector is in rigid connection with the bottom of the scum collector lifting device, the tapered scum collector is connected with the scum collector lifting device, and the scrum collector lifting device is fixed to the bottom of a transfer cart; the tapered scum stopper is connected to the bottom of the scum stopper lifting device, the scum stopper lifting device is fixed to the scum collector lifting device, the scum collector lifting device (3) is rooted on the transfer cart, and the transfer cart is located on transfer rails. The operation method of the molten metal scum quick removal device includes the first step of scum fetching, the second step of transferring and the third step of scum unloading. The molten metal scum quick removal device and the operation method have the advantages that scum removal actions of core components which are the tapered scum collector and the tapered scum stopper are rectilinear motions, the actions are simple, the risk is small, implementation is easy, and the reliability of execution mechanisms is high; the efficiency is high in the whole scum removal process, and heat losses of molten metal are effectively reduced; the molten metal scum quick removal device and the operation method can be adapted to removal of waste scum on the molten metal surface in the metallurgical process.

Description

technical field [0001] The present invention relates to a liquid metal scum quick-cleaning device and an operation method, in particular to a special device suitable for highly efficient removal of liquid metal scum in the process of non-ferrous metallurgy or ferrous metallurgy and its operation process, belonging to field of metallurgical technology. Background technique [0002] In the process of pyrometallurgy, the molten metal is contained in a molten metal ladle coated with heat-resistant materials. Due to the presence of impurities in the molten metal itself, or due to the process of removing impurities, the liquid metal in the molten metal ladle There will be floating dross on the surface whose density is generally lower than that of molten metal. If these scums are not removed cleanly in time, they will have a great impact on the quality of the metal. On the other hand, if the efficiency of the tools used to catch scum is low, it will reduce production capacity, in...
