Abstract
The invention discloses a cast steel roll lower pouring type gating system, which comprises a bottom box, wherein a center circle sand box is connected to the bottom box; an upper roll neck sand box is connected to the center circle sand box; a riser sand box is connected to the upper roll neck sand box; a roll is arranged inside the bottom box, the center circle sand box, the upper roll neck sand box and the riser sand box and comprises an upper roll neck, a roll body and a lower roll neck; the lower roll neck is connected with a central casting pipe; a bottom pouring type gating system is arranged in the central casting pipe; and a refractory brick is arranged in the bottom pouring type gating system. The cast steel roll lower pouring type gating system has the advantages that the molten steel is stably injected, sand and foreign matters in a roll cavity and inclusion in the molten steel easily come up, and the like.
Description
Technical field:
The present invention relates to a kind of cast steel roll bottom pouring type running gate system.
Background technology:
General cast steel roll running gate system molten steel is not steady when injecting, and the field trash in sand grains, foreign matter and the molten steel in the roll die cavity precipitates easily.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide a kind of reliability high, a kind of cast steel roll bottom pouring type running gate system that processing cost is low.
The object of the invention is realized through following technical scheme: a kind of cast steel roll bottom pouring type running gate system; Comprise under casing; Be connected with the centre circle sandbox on the said under casing; Be connected with the roll neck sandbox on the said centre circle sandbox, be connected with the rising head sandbox on the said last roll neck sandbox, said under casing, centre circle sandbox, last roll neck sandbox, rising head sandbox inside are equipped with a roll.Said roll comprises roll neck, the body of roll and following roll neck, and said roll neck down is connected with feed trumpet, and feed trumpet is built-in with bottom gating, is provided with refractory brick in the said bottom gating.
The present invention has the following advantages: molten steel injects steadily, and the field trash in sand grains, foreign matter and the molten steel in the roll die cavity floats easily.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Label among the figure: roll neck, 9-feed trumpet, 10-bottom gating, 11-refractory brick under 1-under casing, 2-centre circle sandbox, the last roll neck sandbox of 3-, 4-rising head sandbox, 5-roll, the last roll neck of 6-, the 7-body of roll, the 8-.
The specific embodiment:
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of cast steel roll bottom pouring type running gate system like Fig. 1; Comprise under casing 1; Be connected with centre circle sandbox 2 on the said under casing 1; Be connected with roll neck sandbox 3 on the said centre circle sandbox 2, said going up on the roll neck sandbox 3 is connected with rising head sandbox 4, said under casing 1, centre circle sandbox 2, go up roll neck sandbox 3, rising head sandbox 4 inside are equipped with a roll 5.Said roll comprises roll neck 6, the body of roll 7 and following roll neck 8.Said roll neck 8 down is connected with feed trumpet 9, and feed trumpet 9 is built-in with bottom gating 10, is provided with refractory brick 11 in the said bottom gating 10.The present invention has molten steel and injects steadily, advantages such as the easy come-up of the field trash in sand grains, foreign matter and the molten steel in the roll die cavity.
