Abstract
The utility model relates to a modified asymmetric style single layer flat bottom plate of pouring lower, it is equipped with two asymmetric runner water passageways in the plate body upper surface center brick cup left and right sides, and the equal resistance loss that each ingot position was realized to the steel hole that emits that differs in aperture through reducing runner water passageway and runner water passageway to guarantee that every ingot mould rises at pouring in-process liquid level parallel and level, has once poured a batch of molten steel into the ingot on same bottom plate. The bottom plate has simple structure and convenient operation, enlarges the number of steel ingots poured at one time, reduces the consumption of the pouring pipe and the refractory material, improves the ingot casting efficiency and the utilization rate of the steel ingot mold, and is easy to popularize and apply.
Description
The utility model is a kind of steel-making ingot casting production bottom board, and the asymmetric that is particularly suitable for the pouring into a mould big section steel ingot single flat base plate of making a bet belongs to the steel-making ingot casting technology.
Auspicious have the steel-making ingot casting generally to adopt symmetrical expression to arrange the ingot mould base plate, is to arrange 4 or 8 ingot moulds about the center with the feed trumpet on a base plate promptly.If will once descend injection forming 6 or 10 steel ingots on same base plate, railway and casting ride face allow the width restriction can't arrange ingot mould because of being driven a vehicle.Produce about 84 tons of good ingot amounts as 80 tons of every stoves of steelmaking converter, if adopt B
84The ingot mould symmetrical expression arranges that every stove molten steel removes 8 B of a base plate that make a bet
84Outside the steel ingot, also the molten steel of remaining 2 steel ingots just need be poured on another piece base plate, is commonly called as " 8+2 " casting.This is to casting car operating rate, and refractory consumption rate is annotated taking of platform, and ingot quality etc. all produce harmful effect.Especially one heat steel water cast twice, prolonged the operating time behind the stove, and promptly the ingot casting time is longer than the duration of heat, thereby has limited the normal performance of converter production capacity, directly has influence on steel output.
The purpose of this utility model provides the single flat base plate of making a bet that a kind of asymmetric is arranged ingot mould, be suitable for once-cast 6 or 10 big section steel ingots, it is long and give mould preparation, ingot casting and steel etc. with one disadvantage to have overcome present symmetrical expression base plate duration of pouring, can make converter smelting and cast operation realize matched well, to satisfy the requirement of STEELMAKING PRODUCTION and steel.
The utility model is achieved in that the asymmetric single flat base plate of making a bet is made up of plate body [1], asymmetric molten stream runner [2] and [8] and center brick cup [5] etc., it is characterized in that: be respectively equipped with two molten stream runners [2] and [8] in the left and right sides of plate body [1] centre of surface brick cup [5], and the length of soup road [2] is longer than soup road [8], and the caliber of soup road [2] is greater than soup road [8].Have steel emitting hole [3] and [7] at Tang Dao [2] and [8] top, and the hole count of steel emitting hole [3] is more than steel emitting hole [8], the aperture of steel emitting hole [3] is greater than steel emitting hole [7].The cross section of molten stream runner is that circle can be oval.
This base plate adopts asymmetric to arrange ingot mould in use, promptly feed trumpet one side is arranged 4 or 6 ingot moulds on the base plate of same port, opposite side is arranged 2 or 4 ingot moulds, by adjusting length, caliber and the steel emitting hole of molten stream runner, realize the drag losses that waits of each ingot position, guarantee the concordant substantially rising of each ingot mould molten steel face in casting process, the one heat steel water of can once having made a bet on same base plate pours into steel ingot, make ingot casting and converter production coupling, thereby guaranteed the output and the quality of steel.
The utility model asymmetric single flat base plate of making a bet is compared with the symmetrical expression flat underside, and its advantage is:
1, the reducing molten stream runner can make the concordant rising of molten steel face in the asymmetric arrangement ingot mould, enlarges the steel ingot number of once making a bet, and has realized smelting and the matched well of pouring into a mould operation, has satisfied the requirement of STEELMAKING PRODUCTION and steel.
2, reduce the consumption and the residual steel loss of cast tube of feed trumpet, refractory material, improved ingot casting efficient and ingot mould utilization rate, reduced base plate and casting car occupancy etc.
3, simple in structure, easy to operate, safe and reliable, be easy to apply.
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is that make a bet single flat base plate and feed trumpet, ingot mould of the utility model asymmetric arranged schematic diagram.
As shown in the figure, the asymmetric single flat base plate of making a bet is made up of plate body [1], molten stream runner [2] and [8], steel emitting hole [3] and [7] and center brick cup [5] etc.Molten stream runner [2] and [8] are positioned at plate body [1] upper surface, center brick cup [5] left and right sides is asymmetric and arranges, the length of molten stream runner [2] is longer than molten stream runner [8], the caliber of molten stream runner [2] is greater than Liu Tangdao [8], molten stream runner is circular cross-section, and molten stream runner [2] is upward gone up steel emitting hole [7] greater than soup road [8] in the aperture of steel emitting hole [3].Ingot mould [4] (identical with the steel emitting hole number) can be arranged as 6 or 10 as required.During cast, as long as go up feed trumpet [6] and ingot mould [4] in place respectively at plate body [1], it is the center of the centrally aligned feed trumpet [6] of center brick cup [5], each steel emitting hole is aimed at the center of ingot mould, molten steel footpath feed trumpet [6] injects center brick cup [5], rise by steel emitting hole and inject every ingot mould [4] in flow through respectively molten stream runner [2] and [8], condensation demoulding mould is steel ingot.
