Description

Technical Field

[0001] This utility model belongs to the technical field of powder metallurgy equipment, and relates to an intermediate casting ladle device, and more specifically to an external anti-overflow device for an intermediate casting ladle for molten steel. Background Technology

[0002] In the field of powder metallurgy, especially in the atomization of metal powders using medium-frequency furnaces, direct casting can damage the high-pressure atomization device. Therefore, high-pressure atomization of metal powders often utilizes an intermediate ladle for casting atomization. This serves two purposes: firstly, to prevent the high-temperature molten steel from scalding the high-pressure atomization device; and secondly, to control the diameter of the ceramic guide tube's leakage hole, which helps control the atomization flow rate, improving atomization efficiency and powder yield. An external anti-overflow device effectively prevents the high-temperature molten steel from overflowing and scalding the high-pressure atomization device. Furthermore, this external anti-overflow device can hold 1200~3500mL of molten steel. The large-capacity intermediate ladle allows for deoxidation and slag removal. When the molten steel temperature decreases, exothermic deoxidizers (such as charcoal, silicon-calcium alloy, etc.) are added to form a heating source, preventing the molten steel from cooling and clogging the intermediate ladle. Utility Model Content

[0003] This invention provides an external anti-overflow device for molten steel intermediate casting ladles to solve the problem of high-temperature molten steel overflowing and scalding high-pressure equipment.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] An external anti-overflow device for a steel molten intermediate ladle, the intermediate ladle including a sandwich-type 304 stainless steel shell, and an external anti-overflow ring connected to the sandwich-type 304 stainless steel shell.

[0006] Magnesium sand ladle is placed inside the sandwiched 304 stainless steel shell, and the bottom hole of the sandwiched 304 stainless steel shell is the installation position of the corundum guide tube.

[0007] The external anti-overflow ring includes an inner ring and an outer ring connected as one piece. The inner ring protrudes downward and the outer ring protrudes upward. The inner ring has the same diameter as the inner ring of the sandwiched 304 stainless steel shell and is nested in the sandwiched 304 stainless steel shell. The outer ring has the same outer diameter as the sandwiched 304 stainless steel shell. The space between the inner and outer rings is coated with refractory material fused magnesia.

[0008] The sandwich-type 304 stainless steel shell is connected to the left and right sides by pull arms. The front end of the pull arm is hooked to the edge of the outer ring, and the external anti-overflow ring is fixed to the sandwich-type 304 stainless steel shell by the pull arm.

[0009] Furthermore, the pull arm is connected to the outer shell of the sandwich-type 304 stainless steel through a hinge support. The pull arm includes a telescopic screw, a barb, and a nut. The barb is connected to the head end of the telescopic screw and hooks the external anti-overflow ring during use.

[0010] Furthermore, handles are welded and fixed to the left and right sides of the outer wall of the sandwich-type 304 stainless steel shell.

[0011] Furthermore, a flange is connected to the lower part of the outer wall of the sandwich-type 304 stainless steel shell, and the sandwich-type 304 stainless steel shell sits on the high-pressure atomizing device during use.

[0012] The beneficial effects of this utility model are as follows:

[0013] This device facilitates the atomization of molten steel at different cooling temperatures. For molten metal with rapid cooling and fast pouring speeds, high-pressure water atomization ladles require a large amount of molten steel for insulation to ensure smooth atomization. The external anti-overflow ring effectively prevents molten steel from overflowing during pouring, thus preventing safety accidents. This molten steel intermediate pouring ladle external anti-overflow device is made of 304 stainless steel, which has certain high temperature resistance and corrosion resistance. It uses a non-fixed connection, is easy to disassemble, and has a simple structure, which is conducive to the assembly and production of intermediate pouring ladles. Attached Figure Description
