Slag ladle molding technology device and use method thereof

Abstract

The invention discloses forming technique equipment of slag pots, and a using method thereof. The technique equipment comprises a cover box and an inner matrix; molded riser head holes are arranged atthe circumference of the cover box, interlaced box belts are positioned in the middle of the cover box, and square holes left by the box belts are consistent with the positions and sizes of suspenders; the inner matrix is in hollow structure, and four suspenders are welded inside the inner matrix, above which a pin hole is arranged, and the positions and sizes of the four suspenders are consistent with the square holes left by the box belts. The method includes the following steps: the inner matrix is placed into a core box and hardened after being filled with molding sand; the cover box is arranged on the inner matrix to cause the cover box to be connected with the inner matrix, and the cover box is hoisted, and a mud core of an intra-cavity slips off the core box and forms an integral upper box with the cover box; the upper box is assembled on a manufactured lower box, and pouring is carried out, and then the pin is withdrawn; firstly, the cover box is hoisted away, finally, the inner matrix is hoisted out, and waste sand on the surfaces of the cover box and the inner matrix is cleared. The equipment and the method do not need to manufacture the core iron of the inner matrix, thus saving the use amount of the molding sand; the core iron is not used, thus reducing the working hours of operation and improving the production efficiency.

Description

1. Technical field: [0001] The invention relates to a process equipment, in particular to a molding process equipment in the manufacturing process of slag pot castings, and also relates to a method for using the process equipment. 2. Background technology: [0002] Slag tank castings are commonly used and vulnerable castings in iron and steel enterprises, and are used in large quantities. The size of the slag tank is large and has a thin-walled bowl-shaped structure. The general shape is that the opening faces downward and the bottom faces upward. It is difficult to arrange the riser of this shape, and it is difficult to make the inner cavity mud core. The applicant has proposed a novel shape, which adopts a structure with the opening facing upward and the bottom facing downward. The riser of this modeling structure is easy to install, which is conducive to the solidification of the casting and the discharge of gas from the inner cavity core, but the molding process and equ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned problems of complex molding process and equipment, especially when making inner cavity clay cores, a large amount of core bone is used for each piece, a large amount of molding sand is consumed, and a lot of man-hours are spent on making core bone, preparing molding sand, and filling a large amount of molding sand, the present invention A set of molding process equipment is provided. The process equipment does not use core bone, and the inner cavity mud core reduces the amount of molding sand and improves production efficiency.
