Problems solved by technology

When the molten iron tank pours the molten iron into the molten iron trough and then flows into the cast iron mold, the molten iron splashes seriously, resulting in a low yield of molten iron and severe slag accumulation in the splash area
The distance between the bottom surface of the nozzle and the cast iron mold cannot be adjusted during installation, which also causes serious splashing of molten iron, and the labor intensity of the operator when cleaning the slag is high, and the working environment is harsh
At the same time, the molten iron flow severely erodes the cast iron mold, which affects the service life of the cast iron mold

Embodiment Construction

[0011] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] As shown in the figure, the buffer and anti-splash dovetail iron launder of the cast iron machine includes the first buffer iron launder 3, the middle transitional iron launder 4 and the tail dovetail iron launder 7, and their shells are all low carbon steel plates It is welded, the inner wall of the groove is welded with anchor nails 8, and the refractory lining 6 is poured.

[0013] The molten iron ladle 1 is lapped on the front pillar 2 and tipped over slowly. The molten iron in the molten iron ladle 1 flows into the first buffer type iron receiving trough 3, and the first buffer type iron receiving trough 3 is installed between the molten iron tank and the middle transitional molten iron launder 4 During the period, the molten iron is poured in the first buffer type iron receiving trough to form a molten pool, and the buffered molten iron flow...

Abstract

The invention discloses a buffering splash-protection dovetail molten iron trough of a pig machine. The trough is designed into two sections of lap joint type dovetail structures and comprises a head buffering molten iron holding slot, a middle transition molten iron trough and a tail dovetail molten iron nozzle. The buffering splash-protection dovetail molten iron trough is integrally arranged between a molten iron tank of the pig machine and the upper chain belt of a driven wheel. Molten iron is cast to the head buffering molten iron holding slot through the molten iron tank and forms a molten bath, thereby relieving the impact of the molten iron. The middle transition molten iron trough buffers the flow of the molten iron twice, and the molten iron and the chain belt forms a 6-10 degree angle of inclination, and the even flow distribution of the molten iron enables the molten iron to evenly flow into a pig mold in a thin and wide waterfall shape. Compared with conventional integral molten iron troughs, the dovetail molten iron trough can reduce molten iron splashes, improve the yield of the molten iron, improve the working environment of operators, relieve the erosion to the pig mold and prolong the service life of the pig mold, and the surface quality of iron blocks is good. Moreover, transportation, installation and debugging are convenient, and meanwhile, the production and maintenance costs are reduced.

Description

technical field [0001] The invention relates to a buffer and anti-splash type dovetail-shaped iron launder used in conjunction with a cast iron machine. Background technique [0002] The molten iron launder is an important supporting equipment of the cast iron machine, through which the molten iron can be continuously injected into the cast iron mold and cooperate with the cast iron machine to complete the process of casting iron. At present, the cast iron machine is equipped with an integral molten iron flow trough with a rectangular cross section, and the molten iron flow nozzle and the chain belt are in a vertical direction. When the molten iron tank poured the molten iron into the molten iron launder and then flowed into the cast iron mold, the molten iron splashed seriously, resulting in a low yield of molten iron and serious slag accumulation in the splash zone. The distance between the bottom surface of the nozzle and the cast iron mold cannot be adjusted during inst...
