The automatic cover opening device installed on the insulation ladle for cast iron pouring

Abstract

The invention discloses an automatic cover opening device arranged on a thermal insulation ladle for pouring cast iron, comprising a ladle body, a hanger, a ladle cover, an overturning shaft and a ladle dumping device. The first-stage worm, the first-stage worm, the second-stage worm, and the second-stage worm are provided with a pair of mounting brackets on the side wall of the ladle cover, and worm gear and worm elevators are arranged on both sides of the mounting frame. Rod, three-stage turbine and screw mandrel, the screw mandrel is connected with the mounting frame; the present invention is provided with a ladle dumping device and a right top cover mechanism, and utilizes the ladle dumping device to connect the left top cover mechanism, the right side top cover mechanism and the The top cover mechanism on the left side moves at the same time to control the up and down movement of the mounting frame, so that the ladle cover can be automatically topped, and the top cover and pouring of the ladle cover can be carried out synchronously, which is beneficial to the heat preservation of the ladle to ensure the pouring temperature of the molten metal and prolong the life of the metal. Liquid cooling time, prolong casting time, achieve the purpose of safe production.

Description

technical field [0001] The invention belongs to the technical field of casting melt containers, such as ladles, tundishes, sprue cups or the like, and in particular relates to an automatic cover opening device arranged on a heat-insulation ladle for cast iron pouring. Background technique [0002] The molten iron ladle is a necessary production equipment in the production of metal casting. It is used to hold the molten metal. When working, the molten iron ladle is poured into the sand casting gate by tilting the ladle. Due to the extremely high temperature of the molten iron, the operation of the molten iron ladle is safe and convenient. Ladle lining material, ladle carrying capacity, etc. all need to be considered. In the actual production process, the molten iron ladle is suspended and moved. If the transfer path and transfer time are slightly longer, the temperature of the molten iron in the ladle will drop significantly. In addition, most of the ladles are equipped with ...

[0002] The molten iron ladle is a necessary production equipment in the production of metal casting. It is used to hold the molten metal. When working, the molten iron ladle is poured into the sand casting gate by tilting the ladle. Due to the extremely high temperature of the molten iron, the operation of the molten iron ladle is safe and convenient. Ladle lining material, ladle carrying capacity, etc. all need to be considered. In the actual production process, the molten iron ladle is suspended and moved. If the transfer path and transfer time are slightly longer, the temperature of the molten iron in the ladle will drop significantly. In addition, most ladles are equipped with insulation covers, but their opening and closing structures are complicated and the insulation effect is poor.
