Honeycomb duct for ladle filler sand and sand adding method for ladle filler sand

Abstract

The invention relates to a honeycomb duct for ladle filler sand. The honeycomb duct (8) comprises a funnel (1), a hollow metal tube (2), a pendulum bob (3), a support (4), two flying rings (5) and a hinge (6); the funnel (1) is located at the top part of the hollow metal tube (2), and is in the shape of a horn mouth; the two flying rings (5) are symmetrically distributed at the outer edge of the funnel (1); the pendulum bob (3) is located on the hollow metal tube (2); the pendulum bob (3) and the hollow metal tube (2) are connected by the hinge (6), so that the pendulum bob (3) can conveniently swing to knock the hollow metal tube (2); the support (4) is located at the tail part of the hollow metal tube (2), and is used for fixing the honeycomb duct (8) in position. According to the honeycomb duct disclosed by the invention, accurate feeding of the ladle filler sand can be ensured, the usage amount of the ladle filler sand is reduced, and the self-opening rate of a ladle is increased.

Description

technical field [0001] The invention relates to iron and steel metallurgical equipment, in particular to a ladle drainage sand diversion pipe and a method for adding sand to the drainage sand. Background technique [0002] Drainage sand is the filling material for the nozzle at the bottom of the ladle, which can be sintered at a lower temperature. The surface facing the steel should not be sintered too thick, otherwise it cannot be poured automatically. The self-opening rate of the ladle is related to the type and quality of the drainage material, steel pouring conditions, refractory materials of the ladle, and the operating level of the workers. Under the premise of optimizing the drainage material, the effect of the addition of drainage sand on the self-opening rate of the ladle is particularly prominent. [0003] There are mainly two ways to add sand to the drainage sand: drop-in type and diversion tube type. The input type sand adding method is to manually input the dr...
