AI Technical Summary

Technical Problem

Traditional fixed-size steel molds cannot meet the casting requirements at the ladle opening after deformation, leading to frequent replacement of refractory bricks and castables, increasing maintenance costs.

Method used

Design a modular mold consisting of a template and a support limiting mechanism. Through components such as positioning pillars, positioning seats, limiting adjustment rods, and limiting parts, the template can be detachably connected and adjusted to adapt to different degrees of deformation at the pouring opening, ensuring the stability of the pouring process.

Benefits of technology

It simplifies the maintenance process, reduces maintenance costs, adapts to the pouring requirements of molten iron ladle opening positions with different degrees of deformation, eliminates the need for separate mold making, and ensures the smooth progress of the pouring process.

Abstract

This utility model discloses a casting mold for the ladle opening of molten iron, including a forming mold composed of several templates connected and assembled into a circular structure, and a supporting and limiting mechanism. The supporting and limiting mechanism is coaxially arranged at the center of the forming mold and is detachably connected to the templates of the forming mold. The supporting and limiting mechanism includes a positioning column, a positioning seat, a limiting adjustment rod, a limiting component, an inner support rod, and a clamp. The positioning column is coaxially arranged at the center of the forming mold. At least one positioning seat is arranged in the upper part of the positioning column. Several limiting adjustment rods are radially arranged on the positioning seat. A limiting component is arranged at the end of each limiting adjustment rod, and the limiting component is connected to the corresponding template. An inner support rod is arranged between each template and the steel shell of the ladle opening. A clamp is arranged at the top of the joint of each template. This utility model can meet the casting and maintenance needs of molten iron ladle openings with different degrees of deformation, eliminating the need to make separate molds for different ladle openings.
