Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Examples

As shown in fig. 1 to 3, the foundry ladle for producing a high-speed steel roll according to the embodiment includes a body 10 and a gate 11 disposed on the body 10; a residue filtering mechanism 20 is arranged between the body 10 and the pouring gate 11, and the residue filtering mechanism 20 comprises a sliding groove 21 arranged on the body 10 and a residue filtering baffle 22 arranged in the sliding groove 21; the density of the filter residue baffle 22 is less than that of the molten iron contained in the body 10.

The filter residue baffle 22 slides up and down in the sliding groove 21, so that when molten iron is poured, the filter residue baffle 22 floats up under the buoyancy of the molten iron, the filter residue baffle 22 only blocks a floating layer on the molten iron, when the pouring amount is large, the amount of molten iron in the pouring gate 11 is large, the filter residue baffle 22 floats up, the molten iron flow opening is enlarged, and the molten iron flow is increased; when the pouring amount is small, the amount of molten iron in the pouring gate 11 is small, the filter residue baffle 22 floats downwards, the molten iron flow opening is reduced, and the molten iron flow is reduced; so that the outflow rate of the molten iron can be changed when impurities on the surface layer of the molten iron are blocked; and the situation that impurities on the surface layer of the molten iron escape from the bottom of the filter residue baffle 22 along with the reduction of the molten iron is avoided.

A transition groove 12 is arranged between the body 10 and the gate 11, and the bottom of the transition groove 12 is perpendicular to the side wall of the body 10; so that the molten iron can stay in the transition groove 12 for a moment and then flows out from the pouring gate 11, and the filter residue baffle 22 can float when the molten iron exists in the transition groove 12, thereby avoiding the phenomenon that the filter residue baffle 22 loses buoyancy and falls after the molten iron in the pouring gate 111 quickly flows out, and causing the residual molten iron in the body 10 to slowly flow out from the gap, and affecting the efficiency.

First limiting bulges 25 are arranged on two sides of the bottom of the filter residue baffle 22, and second limiting bulges 26 matched with the first limiting bulges 25 for use are arranged at the top ends of the sliding grooves 21; play spacing effect, filter residue baffle 22 breaks away from sliding tray 21 when avoiding the molten iron in body 10 too much.

The filter residue baffle 22 comprises a solid baffle area 27 and a filter screen area 28, and the baffle area 27 is arranged above the filter screen area 28; make the molten iron can reach the bottom in solid baffle district 27 fast for filter residue baffle 22 can float fast, can empty in body 10 the molten iron and when finishing soon simultaneously, remaining molten iron can filter out from filter screen district 28, and can not fall after losing buoyancy because filter residue baffle 22, and remaining molten iron can only follow the gap and flow out, influence efficiency.

The top end of the residue retaining plate 22 is provided with a limiting column 23, and a plurality of detachable weight plates 24 are sleeved on the limiting column 23; the draught of the residue baffles 22 is controlled by increasing or decreasing the number of the weight plates 24 at the top ends of the residue baffles 22, so that the weight plates 24 are increased under the condition of more impurities in molten iron, the draught of the residue baffles 22 is increased, and more impurities are blocked; the number of the weight plates 24 is reduced when the impurities are less, so that the draught of the filter residue baffles 22 is reduced, and only the impurities of the molten iron floating layer need to be blocked, thereby accelerating the molten iron pouring speed, and reducing the influence on the molten iron pouring efficiency while filtering the impurities.

At least two limiting columns 23 are arranged; the weight tray 24 is prevented from rotating on the limit column 23, so that the body 10 is unstable, and molten iron is easy to spill.
